Öğe Acute and Chronic Epididymitis(Elsevier Science Bv, 2017) Cek, Mete; Sturdza, Laura; Pilatz, AdrianEpididymitis is a relatively common clinical condition presenting as acute or chronic forms. Acute epididymitis is the inflammation of epididymitis accompanied by pain and swelling, while chronic epididymitis may present only with pain. Etiological factors may be infectious or noninfectious, for example urinary obstruction, drug induced, or idiopathic. Bacterial ascent through the urogenital tract is the most common etiology in acute epididymitis, with Chlamydia trachomatis being isolated in all adult age groups. Diagnosis is generally based on patient history, symptoms, and clinical findings. Recent data indicate that sexually active patients with acute epididymitis should be screened for sexually-transmitted diseases, regardless of their age. Additional laboratory investigations and imaging may be required for differential diagnosis with other intrascrotal conditions, particularly with testicular torsion. Although no evidence-based recommendations can be given for the antimicrobial treatment of acute epididymitis, >85% of bacterial strains causing acute epididymitis are susceptible to fluoroquinoles and third generation cephalosporins. Chronic epididymitis has not been investigated as thorough as acute epididymitis; however, the development and use of a symptom index is promising in terms of achieving a widely-accepted standardization of diagnosis and evaluation. A conservative approach may be beneficial; medical treatment employing antibiotics, anti-inflammatory agents, pain medication, and others are also being utilized without any evidence-based data. Spermatic cord block with short-term and long-term acting agents as well as surgical treatment including epididymectomy microdenervation of the spermatic cord are other treatment alternatives in patients with chronic epididymitis. Patient summary: In this article, we provide an update on the definition, epidemiology, etiology, diagnostics, and therapy in terms of acute and chronic epididymitis.

Despite regional variations in the bacterial spectrum and antibiotic susceptibility patterns, guideline recommendations are usually given on an international level. Objective: To describe the use of AP in urology departments and relate this to relevant parameters such as country, type of hospital, and European Association of Urology guideline recommendations. Design, setting, and participants: Data from the Global Prevalence Study on Infections in Urology for the period 2005-2010 were analysed to evaluate the use of antibiotics in general and AP for urologic procedures. Of the 13 723 patients enrolled, 8178 received antibiotics on the study days. Outcome measurements and statistical analysis: Study data were imported from the Web-based survey into Microsoft Access and exported into SPSS v. 17.0. The data were then coded and analysed. The Pearson chi-Square test was used to compare categorical data and a probability level of 5% was considered significant. Multiple logistic regression analysis was used to define significantly different variables in multiple set categories. Results and limitations: Questions on AP were answered on 8370 forms and 6306 (75.3%) investigators reported their routine application of AP. Routine AP was highest in Latin America (n = 337; 84%), followed by Asia (n = 1338; 86%), Africa (n = 234; 85%), and Europe (n = 4116; 67%). The antibiotics most frequently used for AP were second-generation cephalosporins, ciprofloxacin, cefotaxime, and amoxicillin plus beta-lactamase inhibitor. Conclusions: There were significant differences between countries/regions and types of hospitals, both in using AP for clean procedures and in the types of antibiotics used. AP was not always consistent with recommended guidelines. (C) 2012 European Association of Urology. Published by Elsevier B.V.

E.; Bartoletti, Ricardo; Cek, Mete; Grabe, Magnus; Kahlmeter, Gunnar; Pickard, Robert; Bjerklund-Johansen, Truls E.[Abstract Not Available]Öğe Antimicrobial resistance in urosepsis: outcomes from the multinational, multicenter global prevalence of infections in urology (GPIU) study 2003-2013(Springer, 2016) Tandogdu, Zafer; Bartoletti, Ricardo; Cai, Tomasso; Cek, Mete; Grabe, Magnus; Kulchavenya, Ekaterina; Koves, BelaPrimary objective was to identify the (1) relationship of clinical severity of urosepsis with the pathogen spectrum and resistance and (2) appropriateness of using the pathogen spectrum and resistance rates of health-care-associated urinary tract infections (HAUTI) as representative of urosepsis. The secondary objective was to provide an overview of the pathogens and their resistance profile in patients with urosepsis. A point prevalence study carried out in 70 countries (2003-2013). Population studied included; 408 individuals with microbiologically proven urosepsis, 1606 individuals with microbiological proof of HAUTI and 27,542 individuals hospitalised in urology wards. Main outcomes are pathogens and resistance identified in HAUTIs and urosepsis including its clinical severity. A statistical model that included demographic factors (study year, geographical location, hospital setting) was used for analysis. Amongst urology practices, the prevalence of microbiologically proven HAUTI and urosepsis was 5.8 and 1.5 %, respectively. Frequent pathogens in urosepsis were E. coli (43 %), Enterococcus spp. (11 %), P. aeruginosa (10 %) and Klebsiella spp. (10 %). Resistance to commonly prescribed antibiotics was high and rates ranged from 8 % (imipenem) to 62 % (aminopenicillin/beta lactamase inhibitors); 45 % of Enterobacteriaceae and 21 % of P. aeruginosa were multidrug-resistant. Resistance rates in urosepsis were higher than in other clinical diagnosis of HAUTI (Likelihood ratio < 0.05). It is not appropriate to use the pathogen spectrum and resistance rates of other HAUTIs as representative of urosepsis to decide on empirical treatment of urosepsis. Resistance rates in urosepsis are high, and precautions should be made to avoid further increase.Öğe Aspects of urinary tract infections and antimicrobial resistance in hospitalized urology patients in Asia: 10-Year results of the Global Prevalence Study of Infections in Urology (GPIU)(Elsevier Science Bv, 2018) Choe, Hyun-Sop; Lee, Seung-Ju; Cho, Yong-Hyun; Cek, Mete; Tandogdu, Zafer; Wagenlehner, Florian; Bjerklund-Johansen, Truls ErikObjectives: To assess Asian data from Global Prevalence Study on Infections in Urology (GPIU study) which has been performed more than 10 years. Methods: Seventeen Asian countries participated in the GPIU study between 2004 and 2013. Data for these countries were collected from the web-based GPIU database. The point prevalence of urinary tract infections (UTI) and antimicrobial susceptibility of representative pathogens were analysed for Asian geographic regions. Results: A total of 6706 patients (5271 male, 1435 female) were assessed during the study period, and 659 patients were diagnosed with a UTI (9.8%). Of these UTI patients, 436 were male and 223 were female. Mean patient age was 54.9 +/- 19.3 years. Pyelonephritis and cystitis were the most common clinical diagnoses, representing 30.7% and 29.9% of patients, respectively. Escherichia coli was the most frequently identified uropathogen (38.7%). For the patients with urinary tract infection, cephalosporins were the most frequently used antibiotics (34.4%), followed by fluoroquinolones (24.1%), aminoglycosides (16.8%). Fluoroquinolone resistance was relatively high (ciprofloxacin 54.9%, levofloxacin 39.0%), and cephalosporin resistance 42% (42.5-49.4%). Of the antibiotics evaluated, uropathogens had maintained the highest level of susceptibility to amikacin and imipenem (24.9% and 11.3% resistance rates, respectively). Conclusion: Uropathogens in many Asian countries had high resistance to broad-spectrum antibiotics. Knowledge of regional and local resistance data and prudent use of antibiotics are important for proper management of UTI in Asian countries.

Methods: Between January and December 2012, a total of 215 patients applying to our outpatient clinic with lower urinary tract symptoms were evaluated, prospectively. Patients with a prostate-specific antigen level of 2.5-10 ng/mL and/or suspicious digital rectal examination were included in the study. Exclusion criteria were determined as recent pelvic radiotherapy, lower urinary tract surgery, history of acute urinary retention, or indwelling urinary catheter. Biopsies were taken systematically with at least 10 cores considering prostate volume and patient age. According to Vienna nomogram, in patients requiring 6- or 8-core biopsies, tissue sampling was completed to 10 cores (our standard protocol), whereas in patients requiring more than 10 cores additional tissue sampling was performed. Results: After the determination of inclusion/exclusion criteria, 170 patients were enrolled in our study. The median (min-max) age, prostate-specific antigen value, and prostate volume were 65 (48-86) years, 7.6 ng/dL (2.5-10), and 55 cc (17-150), respectively. Prostate cancer was detected in 49 (28.8%) patients with transrectal ultrasound-guided prostate biopsy according to the Vienna nomogram. We found that our standard 10-core biopsy protocol would have diagnosed prostate cancer in 46 (27.1%) patients in the same study group showing no statistically significant difference (p > 0.005). Conclusion: The findings of this study suggest that considering cancer detection rates no statistically significant differences were found between both methods. Further prospective research in this aspect is needed to define the ultimate prostate biopsy protocol.Öğe Condition-specific surveillance in health care-associated urinary tract infections as a strategy to improve empirical antibiotic treatment: an epidemiological modelling study(Springer, 2020) Tandogdu, Zafer; Koves, Bela; Cai, Tommaso; Cek, Mete; Tenke, Peter; Naber, Kurt; Wagenlehner, FlorianBackground Health care-associated urinary tract infection (HAUTI) consists of unique conditions (cystitis, pyelonephritis and urosepsis). These conditions could have different pathogen diversity and antibiotic resistance impacting on the empirical antibiotic choices. The aim of this study is to compare the estimated chances of coverage of empirical antibiotics between conditions (cystitis, pyelonephritis and urosepsis) in urology departments from Europe. Methods A mathematical modelling based on antibiotic susceptibility data from a point prevalence study was carried. Data were obtained for HAUTI patients from multiple urology departments in Europe from 2006 to 2017. The primary outcome of the study is the Bayesian weighted incidence syndromic antibiogram (WISCA) and Bayesian factor. Bayesian WISCA is the estimated chance of an antibiotic to cover the causative pathogens when used for first-line empirical treatment. Bayesian factor is used to compare if HAUTI conditions did or did not impact on empirical antibiotic choices. Results Bayesian WISCA of antibiotics in European urology departments from 2006 to 2017 ranged between 0.07 (cystitis, 2006, Amoxicillin) to 0.89 (pyelonephritis, 2009, Imipenem). Bayesian WISCA estimates were lowest in urosepsis. Clinical infective conditions had an impact on the Bayesian WISCA estimates (Bayesian factor > 3 in 81% of studied antibiotics). The main limitation of the study is the lack of local data. Conclusions Our estimates illustrate that antibiotic choices can be different between HAUTI conditions. Findings can improve empirical antibiotic selection towards a personalized approach but should be validated in local surveillance studies.Öğe The effect of smoking on spontaneous passage of distal ureteral stones(Bmc, 2014) Fazlioglu, Adem; Salman, Yilmaz; Tandogdu, Zafer; Kurtulus, Fatih Osman; Bas, Serap; Cek, MeteBackground: Animal studies have shown that nicotine affects the peristalsis of the ureter. The aim of the study is to analyze the effect of smoking on spontaneous passage of distal ureteral stones. Methods: 88 patients in whom distal ureteral stone below 10 mm diameter diagnosed with helical computerized tomography enhanced images were reviewed. Patients were grouped as either smokers (n:33) or non smokers (n:50). Follow-up for spontaneous passage of stones was limited with 4 weeks. Patients did not receive any additional medical treatment other than non-steroid anti inflamatory drugs only during painful renal colic episodes. Two groups were compared with the chi-square test in terms of passing the stone or not. Stone passage was confirmed with either the patient collecting the stone during urination or by helical CT. Results: Smoking habits was present in 30(34%) patients and the frequency in both groups were similar (smokers: 23(76%) vs non-smokers: 46(79%)). Spontaneous passage of the stone was observed in 69(78%) patients. The two groups were comparable in terms of patien age, male to female ratio and stone size. Stone passage decreased as stone diameter increased. Total stone passage rates were similar in both groups (smokers: 76% vs. non-smokers: 79%) (p > 0.05). Passage of stones > 4 mm was observed in 46% and 67% of smokers and non-smokers respectively. However passage of stones with a diameter <= 4 mm were similar in both groups (smokers: 100% vs non-smokers: 92%) (p > 0.05). Conclusion: Smoking has neither a favorable nor un-favorable effect on spontaneous passage of distal ureteral stones. However, spontaneous passage rates in patients with a stone diameter > 4 mm was lower in smokers. These results should be further confirmed with studies including larger numbers of patients.Öğe Epidemiology, treatment and prevention of healthcare-associated urinary tract infections(Springer, 2012) Wagenlehner, F. M. E.; Cek, Mete; Naber, Kurt G.; Kiyota, Hiroshi; Bjerklund-Johansen, Truls E.Objectives Healthcare-associated urinary tract infections (HAUTIs) are the most frequent healthcare-associated infections in general hospitals. They are almost exclusively complicated UTIs, although complicating factors are very heterogenous. HAUTIs are mainly catheter associated. Most of them are asymptomatic and do not need antimicrobial therapy. However, cross-contamination and cross-infection may contribute to distribution of resistant uropathogens. The bacterial spectrum of HAUTI is broad, and antibiotic resistance is common. Methods The authors reviewed the literature from 2000 to 2010 to determine the epidemiology, prevention and best treatment strategies for HAUTI. The recommendations were summarized by determining the level of evidence and grading each recommendation. Results The treatment for HAUTI encompasses treatment for complicating factors as well as antimicrobial chemotherapy. At least in serious UTI, adequate initial antibiotic therapy results in lower mortality. Therefore, the initial antibiotic regimen must provide sufficient antibiotic coverage. This can only be achieved if the local or regional bacterial spectrum and antibiotic resistance patterns of uropathogens are followed continuously. Provisional microbiological findings, such as reports on Gram-stain or certain biochemical results, can lead to early stratification of pathogens and allow a more tailored empiric antibiotic therapy. Antibiotic therapy of HAUTI has to consider therapeutic success in the individual patient and prevention of emergence of antibiotic-resistant mutants. For both aspects, adequate drug selection and dosing are paramount. Discussion Antibiotic treatment for HAUTI should follow prudent antibiotic use to prevent emergence of antibiotic resistance.Öğe The Global Prevalence of Infections in Urology (GPUI) Study: A Worldwide Surveillance Study in Urology Patients(Elsevier, 2016) Wagenlehner, Florian; Tandogdu, Zafer; Bartoletti, Riccardo; Cai, Tommaso; Cek, Mete; Kulchavenya, Ekaterina; Koves, Bela[Abstract Not Available]Öğe The Global Prevalence of Infections in Urology Study: A Long-Term, Worldwide Surveillance Study on Urological Infections(Mdpi, 2016) Wagenlehner, Florian; Tandogdu, Zafer; Bartoletti, Riccardo; Cai, Tommaso; Cek, Mete; Kulchavenya, Ekaterina; Koeves, BelaThe Global Prevalence of Infections in Urology (GPIU) study is a worldwide-performed point prevalence study intended to create surveillance data on antibiotic resistance, type of urogenital infections, risk factors and data on antibiotic consumption, specifically in patients at urological departments with healthcare-associated urogenital infections (HAUTI). Investigators registered data through a web-based application (http://gpiu.esiu.org/). Data collection includes the practice and characteristics of the hospital and urology ward. On a certain day in November, each year, all urological patients present in the urological department at 8:00 a.m. are screened for HAUTI encompassing their full hospital course from admission to discharge. Apart from the GPIU main study, several side studies are taking place, dealing with transurethral resection of the prostate, prostate biopsy, as well as urosepsis. The GPIU study has been annually performed since 2003. Eight-hundred fifty-six urology units from 70 countries have participated so far, including 27,542 patients. A proxy for antibiotic consumption is reflected by the application rates used for antibiotic prophylaxis for urological interventions. Resistance rates of most uropathogens against antibiotics were high, especially with a note of multidrug resistance. The severity of HAUTI is also increasing, 25% being urosepsis in recent years.Öğe Healthcare-associated urinary tract infections in hospitalized urological patients-a global perspective: results from the GPIU studies 2003-2010(Springer, 2014) Cek, Mete; Tandogdu, Zafer; Wagenlehner, Florian; Tenke, Peter; Naber, Kurt; Bjerklund-Johansen, Truls ErikEuropean Section for Infections in Urology has been conducting an annual prevalence survey investigating various aspects of healthcare-associated urinary tract infections (HAUTI) since 2003. The data on various clinical categories of HAUTI, the contamination status of HAUTI patients who underwent any urological intervention with regard to microorganisms isolated, resistance status and antibiotics used to treat HAUTI will be presented. Of a total of 19,756 patients screened, 1,866 patients had HAUTI (9.4 %); 1,313 males (70.4 %) and 553 (29.6 %) females. Mean age was 59.9 +/- A 18.2. Asymptomatic bacteriuria (ASB) and cystitis were the most frequent clinical diagnoses representing 27.0 and 26 % of all HAUTI, respectively. Echerichia coli was found to be the most frequent uropathogen (544 of 1,371 isolates) (39.7 %). Fluoroquinolones were preferred in 26.6 % of cases followed by cephalosporins (23.3 %), aminoglycosides (14.1 %) and penicillins (13.8 %). High global resistance rates to ciprofloxacin (> 50 %), cephalosporins (35-50 %) and penicillins (50 %) were found in the GPIU studies 2003-2010. We showed that around 10 % of hospitalized urological patients are at risk to develop HAUTI often caused by multiresistant uropathogens. Increased antibiotic use often with broad-spectrum antimicrobials will inevitably be followed by increasing bacterial resistance. To interrupt such a vicious cycle, our results suggest (1) there is still room for improvement in surgical prophylaxis in terms of limiting exposure to antibiotics and (2) far too many patients with ASB are being treated which shows that the new proposal of classification should be adopted where ABS is regarded as colonization and not as an infection to be treated.Öğe Infective Complications After Prostate Biopsy: Outcome of the Global Prevalence Study of Infections in Urology (GPIU) 2010 and 2011, A Prospective Multinational Multicentre Prostate Biopsy Study(Elsevier, 2013) Wagenlehner, Florian M. E.; van Oostrum, Edgar; Tenke, Peter; Tandogdu, Zafer; Cek, Mete; Grabe, Magnus; Wullt, BjornBackground: Infection is a serious adverse effect of prostate biopsy (P-Bx), and recent reports suggest an increasing incidence. Objective: The aim of this multinational multicentre study was to evaluate prospectively the incidence of infective complications after P-Bx and identify risk factors. Design, setting, and participants: The study was performed as an adjunct to the Global Prevalence Study of Infections in Urology (GPIU) during 2010 and 2011. Men undergoing P-Bx in participating centres during the 2-wk period commencing on the GPIU study census day were eligible. Outcome measurements and statistical analysis: Baseline data were collected and men were questioned regarding infective complications at 2 wk following their biopsy. The Fisher exact test, Student t test, Mann-Whitney U test, and multivariate regression analysis were used for data analysis. Results and limitations: A total of 702 men from 84 GPIU participating centres worldwide were included. Antibiotic prophylaxis was administered prior to biopsy in 98.2% of men predominantly using a fluoroquinolone (92.5%). Outcome data were available for 521 men (74%). Symptomatic urinary tract infection (UTI) was seen in 27 men (5.2%), which was febrile in 18 (3.5%) and required hospitalisation in 16 (3.1%). Multivariate analysis did not identify any patient subgroups at a significantly higher risk of infection after P-Bx. Causative organisms were isolated in 10 cases (37%) with 6 resistant to fluoroquinolones. The small sample size per participating site and in compared with other studies may have limited the conclusions from our study. Conclusions: Infective complications after transrectal P-Bx are important because of the associated patient morbidity. Despite antibiotic prophylaxis, 5% of men will experience an infective complication, but none of the possible factors we examined appeared to increase this risk. Our study confirms a high incidence of fluoroquinolone resistance in causative bacteria. (C) 2012 European Association of Urology. Published by Elsevier B.V.

The study aims at the translation of the ACSS into Turkish from the original Uzbek including its linguistic, cognitive and clinical validation.Materials and Methods: After forward and backward translation of the ACSS from Uzbek to Turkish and vice versa, the cognitive assessment of the Turkish ACSS was performed on 12 female subjects to achieve the final study version.Results: The clinical validation was performed on a total of 120 female respondents including 64 Patients with AC and 56 controls without AC. For clinical diagnosis of AC, the predefined summary score of the typical symptoms of >6 showed high values (95% confidence interval) for sensitivity (0.88 [0.77-0.94]), specificity (0.98 [0.91-1.00]), and diagnostic accuracy (0.93 [0.86-0.97]). All patients were followed up between five to nine days after the baseline visit. Forty-four (68.75%) patients used antimicrobial treat-ment, whereas the rest (31.25%) preferred non-antimicrobial treatment. The severity scores of the typical symptoms and the qual-ity of life were reduced significantly at follow-up. Using different (favored) thresholds for successful and non-successful treatment a clinicalsuccess rate between 54.7% and 64.1% (60.9%) was achieved.Conclusions: After translation from the original Uzbek and cognitive assessment, the Turkish ACSS showed similar good results for clinical diagnosis and patient-reported outcome as in other languages validated so far and could therefore now be used for clinical studies as well as in everyday practice.Öğe Preoperative assessment of the patient and risk factors for infectious complications and tentative classification of surgical field contamination of urological procedures(Springer, 2012) Grabe, Magnus; Botto, Henry; Cek, Mete; Tenke, Peter; Wagenlehner, Florian M. E.; Naber, Kurt G.; Johansen, Truls E. BjerklundPurpose To assess the patient and identify the risk factors for infectious complications in conjunction with urological procedures and suggest a model for classification of the procedures. Method Review of literature, critical analysis of data and tentative model for reducing infectious complications. Results Risk factors are bound to the patient and to the procedure itself and are associated with the environment where the healthcare is provided. Assuming a clean environment and sterile operation Weld, a five-level assessment ladder related to the patient and type of surgery is useful, considering: (1) the ASA score, (2) the general risk factors, (3) the individual endogenous and exogenous risk factors, (4) the class of surgery and the potential bacterial contamination burden and (5) the level of severity and difficulty of the surgical intervention. A cumulative approach will identify the level of risk for each patient and define preventive measures, such as the type of antibiotic prophylaxis or therapeutic measures before surgery. There are data suggesting that the higher the ASA score, the higher is the risk of infectious complication. Age, dysfunction of the immune system, hypo-albuminaemia/malnutrition and overweight, uncontrolled blood glucose level and smoking are independent general risk factors, whilst bacteriuria, indwelling catheter treatment, urinary tract stone disease, urinary tract obstruction and a history of urogenital infection are specific urological risk factors. There is inconclusive evidence for most other reported risk factors. The level of contamination of the surgical Weld is of utmost importance as are the procedure-related factors, and the sum of these have to be reflected on for the subsequent perioperative management of the patient. Conclusions It is essential to identify and control risk factors to minimize infectious complications in conjunction with urological procedures. Our knowledge is limited and clinical research and quality registries analysing risk factors must be undertaken. We propose a working basis for assessment of patients' risk factors and classification of urological procedures.Öğe Reply from Authors re: Riccardo Bartoletti, Tommaso Cai. Prostate Biopsies Should Be Performed According to a Standard of Care. Eur Urol 2013;63:528-9(Elsevier Science Bv, 2013) Wagenlehner, Florian; van Oostrum, Edgar; Tenke, Peter; Tandogdu, Zafer; Cek, Mete; Grabe, Magnus; Wullt, Bjorn[Abstract Not Available]Öğe Resistance patterns of nosocomial urinary tract infections in urology departments: 8-year results of the global prevalence of infections in urology study(Springer, 2014) Tandogdu, Zafer; Cek, Mete; Wagenlehner, Florian; Naber, Kurt; Tenke, Peter; van Ostrum, Edgar; Johansen, Truls BjerklundTo present the worldwide antibiotic resistance rates of uropathogens reported in nosocomial urinary tract infections (NAUTI) during the period of 2003-2010. Data from the Global Prevalence Study of Infections in Urology from the period of 2003-2010 were analyzed to evaluate the resistance rates of pathogens causing NAUTI. The web-based application was used to record data of investigators from urology departments participating in the study every year during the days allocated in November. Each center was allowed to enter data on a single day of the study. The point prevalence data was used to find differences among geographic regions and years by utilizing multiple logistic regression analysis. A total of 19,756 patients were hospitalized during the study period, and in 1,866 of them, NAUTI was reported. Proof of infection was reported in 1,395 patients. Resistance rates of all antibiotics tested other than imipenem against the total bacterial spectrum were higher than 10 % in all regions. Resistance to almost all pathogens was lowest in North Europe, and there is no single year where an outbreak of resistance has been detected. The resistance rates of most of the uropathogens against the antibiotics tested did not show significant trends of increase or decrease with Asia exhibiting the highest rates in general. The only antibiotic tested with an overall resistance rate below 10 % was imipenem. Knowledge of regional and local resistance data and prudent use of antibiotics are necessary to optimize antibiotic therapy in urological patients with NAUTI.Öğe Semirigid ureteroscopy: the effect of previous ipsilateral intraureteral manipulations on stone clearance(Springer, 2012) Kurtulus, Fatih O.; Avci, Egemen; Tandogdu, Zafer; Gungor, Ruhi; Karaca, Sener; Fazlioglu, Adem; Cek, MeteWe investigated whether previous intraureteral manipulations had an effect on the stone-free rates (SFR) after semi-rigid ureteroscopy (URS) with pneumatic lithotripsy. A retrospective review of all patients who were treated for ureteral stones at two different institutions from June 2003 through January 2010 was performed. Data of 161 URS procedures were analyzed. Stone size, location (distal, mid and proximal) and number (single and multiple), patient demographics and previous intraureteral manipulations were recorded. Patients were grouped as having undergone a previous ipsilateral intraureteral manipulation (Group 1) or not (Group 2). Stone location and number, stone clearance and ancillary procedures were compared. There were no significant differences between Group 1 versus Group 2 for age (p > 0.05), gender (p > 0.05), stone site (p > 0.05) and stone size (p > 0.05). Stones with multiple locations were more frequent in Group 1 (18.5%); however, the difference did not reach statistical significance between the two groups. Similarly, the frequency of multiple stones was also higher in Group 1 (29.6%). Stone site, diameter and gender were comparable in both groups. Stone-free rate of all patients was 84.6% after the first intervention. This rate increased to 98.1% after secondary procedures. Univariate analysis revealed that SFR after URS were low in patients who underwent previous intraureteral manipulations (Group 1:55.6% vs. Group 2:89.1%). SFR after the first intervention were related with stone size, location and number. Additionally, multiple logistic regression analysis indicated a relationship between previous intraureteral manipulations and initial stone clearance rates. Spontaneous passage of stone fragments after URS was associated with stone burden, location, number and previous intraureteral manipulations. Further multiple logistic regression analysis showed that only previous intraureteral manipulations were associated with the expulsion of the stones left for passage.Öğe The therapy for urogenital tuberculosis(Marmara Univ, Fac Medicine, 2023) Kulchavenya, Ekaterina; Cek, MeteTuberculosis (TB) is a communicable disease that is a major cause of ill health. Urogenital TB was a frequent urological disease in the pre-antibiotic era: about 20% of patients in urological hospitals had renal TB, mostly in the form of pyonephrosis. We composed a narrative review of the literature with keywords urogenital tuberculosis', prostate tuberculosis kidney tuberculosis, treatment of tuberculosis.Urogenital TB (UGTB) includes TB of the kidney and the urinary tract and male and female genital TB. Each clinical presentation requires tailored antibiotic therapy depending on stage and general management. Anti-TB therapy should be multicomponent, continuous, long-lasting and controlled with a follow-up for 2-3 years. Otherwise, the risks of development of drug-resistance and relapse increase.Index of suspicion on UGTB is generally low, causing a delay in diagnosis; consequently, complicated forms of UGTB respond poorly to anti-TB therapy, while timely diagnosed minor forms are curable medically without surgery. Even with timely diagnosed UGTB, non-optimal therapy may result in over-fibrosis, scarring and strictures of the urinary tract, making surgical repair inevitable. Nevertheless, we have a wide enough spectrum of anti-TB drugs to cure urogenital TB.
