    Partial Nephrectomy of a Horseshoe Kidney With Renal-Cell Carcinoma and Cholecystectomy: a Case Report
    (Trakya Üniversitesi, 2020) Cengiz, Elif; Şişman, Fevzi Oktay; Koçyiğit, Beliz; Arıkan, Mehmet Gürkan; Aktoz, Tevfik
    Aims: Horseshoe kidneys are the most common type of renal fusion anomaly and it may be associated with other anomalies and complications. Our case aims to present the partial nephrectomy of a horseshoe kidney with renal-cell carcinoma and cholecystectomy. Case Report: A sixty-year-old male patient was admitted to our outpatient clinic with a 3 cm suspicious mass in the horseshoe kidney that was detected during an attack of acute cholecystitis. Computed tomography revealed a heteroge- neous hypodense lesion containing millimetric calcific foci of 35x31x33 mm in size at the ventral middle part of the right kid- ney. Partial nephrectomy was performed non-ischemically and then cholecystectomy was performed. Pathological examination revealed stage T1a clear cell renal carcinoma, WHO/ISUP Grade 2 with a negative surgical margin. During follow-up; urea, creatinine, and glomerular filtration rate were found to be normal. Conclusion: Horseshoe kidneys are fairly common among renal anomalies. Cholecystectomy following non-ischemic partial nephrectomy for a tumor in the horseshoe kidney is a rare case.

    Case Report of An Incidental Unicentric Castleman Disease
    (Trakya Üniversitesi, 2021) Cengiz, Elif; Certel, Alperen Taha; Ayrık, Mert Yücel; Arıkan, Mehmet Gürkan; Mercan, Elif; Öz Puyan, Fulya; Atakan, İrfan Hüseyin
    Aims: To emphasize the hardship of diagnosing Castleman disease and present a potential treatment method. Case Report: A sixty-three-year-old male patient was admitted to the outpatient clinic with an attack of acute cholecystitis. The patient’s abdominal computed tomography revealed an incidentally detected lipid dense solid mass (64x53x37 mm) at the level of right renal hilum with 29x13 mm solid components in the middle. The patient was admitted to the urology department and underwent surgery where the mass was totally excised due to suspicion of a malignancy (liposarcoma). Histopathological examination later on resulted with unicentric Castleman disease, hyaline vascular subtype. Conclusion: Since unicentric Castleman disease has an asymptomatic clinical course and is quite rare, it is necessary to rule out many potential possibilities before reaching a proper diagnosis. However, unicentric Castleman disease usually exhibits a good prognosis after the removal of the affected lymph node. Still, Castleman disease should be a candidate considered in the differential diagnosis of patients with incidentally discovered lymphadenopathy. On the whole, for a better understanding of underlying pathophysiology, there still lies a gap to be filled with knowledge acquired through further studies.

    Renal cell carcinoma manifesting after extracorporeal shockwave lithotripsy, percutaneous nephrolithotomy and open surgery for cystine calculus
    (2010) Kaplan, Mustafa; Kleın, Eric
    Böbrek taş hastalığının renal pelvis kanseri için önemli bir risk faktörü olduğu yönünde bir çok araştırma olsa da böbrek taş hastalığı ile renal hücreli karsinom birlikteliği çok iyi bilinmemekte ve bu konuda çok az olgu sunumu tarzında yayın mevcuttur. Biz burada bilateral böbrek taşı nedeniyle daha önce vücut dışı şok dalgaları, perkütan nefrolitotripsi ve açık cerrahi sonrası bilateral renal hücreli karsinom tanısı alan bir olguyu sunmaya çalıştık. Uzun süreli böbrek taşı bulunan olguların uygun yöntemlerle renal parankim tümörü açısından da izlenmesi gerekir.

    Rare Fibroepithelial Polyp Extending Along the Ureter: A Case Report
    (2018) Akdere, Hakan; Çevik, Gökhan
    Background: Fibroepithelial polyps of the urinary tract are rare tumors, and their occurrence in the upper urinary tract is highly unusual. Case Report: This study reports a 9-year-old boy who presented to our clinic with complaints of unilateral flank pain and macroscopic hematuria. The direct urinary system graph did not show stone formation; therefore, magnetic resonance urography was performed. This revealed a filling defect in the left proximal ureter. On cystoscopy, a polyp was seen in the orifice of the left ureter, extending along the ureter. The polyp was resected by laser ablation and removed from the ureter. Histopathologic examination revealed a fibroepithelial polyp comprising fibrovascular stroma covered with transitional epithelium. Conclusion: Although extremely rare, a fibroepithelial polyp should be considered in the differential diagnosis when a young patient presents with flank pain and macroscopic hematuria. Endoscopic procedures may be the treatment of choice for polyps located in the upper ureter.

    A case of urachal malacoplakia that seems like urachal cancer
    (2015) İnci, Osman; Taştekin, Ebru; Gençhellaç, Hakan; Arabacı, Özcan; İşler, Serap; Atakan, İrfan Hüseyin
    Background: Urachal masses observed in adults should be considered malignant unless they are confuted. It is very difficult to differentiate between malignant or benign lesions, including especially calcified foci and solid areas. Case Report: Our case was a 63-year-old male patient who was diagnosed as Behçet’s Disease 26 years ago. Upon clinical examination, he was also diagnosed with adenocarcinoma of prostate. He was examined by computerized tomography to define the stage of prostatic adenocarcinoma. The existence of a hypodense multiseptated cystic lesion with irregular margins and solid areas located between anterosuperior of bladder and umbilicus was reported. Hence, the lesion was evaluated as urachal carcinoma and locally advanced prostate cancer by the urooncology council. Resection of the mass, partial cystectomy and pelvic lymphadenectomy were performed as one of the surgical approach options in urachal carcinoma. After pathological examination, the mass was diagnosed as malakoplakia and metastasis of prostate adenocarcinoma was also detected in the right obdurator lymph nodule. In the literature, case reports of urachal malakoplakia are extremely rare. It is also interesting to note the absence of specific clinical symptoms for the urachal mass and the existence of concomitant adenocarcinoma in our case. Conclusion: Malakoplakia can only be diagnosed by pathological examination. Particularly, urachal malakoplakia should also be taken into consideration in the differential diagnosis of lesions which include solid areas and are located in the urachus. Keywords: Michaelis Gutmann bodies, urachal malacoplakia, urachal malacoplakia mimicking cancer

    Protective effect of quercetin against renal toxicity induced by cadmium in rats
    (2012) Aktoz, Tevfik; Kanter, Mehmet; Uz, Yeşim Hülya; Aktaş, Cevat; Erboğa, Mustafa; Atakan, İrfam Hüseyin
    Amaç: Çalışmamızda kadmiyumla (Cd) oluşturulan böbrek toksisitesine karşı quercetinin (QE) koruyucu etkinliğini göstermeyi amaçladık. Hastalar ve Yöntemler: Çalışmada 24 adet Wistar albino cinsi erişkin erkek sıçan kullanıldı. Sıçanlar her grupta 8 adet olmak üzere; kontrol, Cd ve Cd+QE olmak üzere 3 gruba ayrıldı. Cd grubuna her gün 1 mg/kg Cd, 2 ml/kg serum fizyolojik içerisinde çözündürüldükten sonra CdCl2 şeklinde 30 gün boyunca subkutan enjeksiyon olarak uygulandı. Cd ile birlikte QE tedavisi verilen gruba, Cd enjeksiyonundan 2 gün önce başlanarak 15 mg/kg QE, deney süresi boyunca intraperitoneal olarak uygulandı. Bulgular: Böbrek dokularının histolojik olarak değerlendirilmesi sonucu, kontrol grubuyla karşılaştırıldığında Cd verilen sıçanlarda mezengial hücrelerde artış, kapsüler, glomerüler ve tübüler basal membranlarda kalınlaşma ile birlikte periyodik asit Schiff (PAS)-pozitif alanların artışı gözlendi. Cd ile birlikte QE tedavisi verilen grupta sadece birkaç glomerüldeki genişleme dışında, Cd’ye bağlı böbrek yapısında oluşan değişikliklere karşı QE’nin belirgin koruyucu bir etkisinin olduğu saptandı. Bulgularımız, Cd ile birlikte QE tedavisi verilen grupta böbrek kortikal dokularında TdT-(terminal deoksinukleotidil transferaz)- aracılı deoksiuridin trifosfat işaretleme (TUNEL) aktivitesinde anlamlı bir azalma ile birlikte prolifere olmuş hücre nükleer antijeninin (PCNA) ekspresyonunda da artış olduğunu göstermiştir. Sonuç: Bu sonuçlar QE’nin Cd ile oluşturulan böbrek toksisitesini azaltabileceğini göstermiştir.

    Bilateral same-session flexible ureterorenoscopy for renal and/or ureteric stone disease treatment
    (Arab Assoc Urology, 2018) Arda, Ersan; Cakiroglu, Basri
    Objective: To evaluate the effectiveness and safety of bilateral same-session flexible ureterorenoscopy (f-URS) in the treatment of bilateral renal and/ or ureteric stone disease. Patients and methods: From October 2007 to December 2015, 62 patients who had undergone bilateral, same-session f-URS were included in the study. The procedures were performed under general anaesthesia, in lithotomy, and initiated on the side in which the patient was clinically symptomatic or on the side in which the stone was smaller. Plain abdominal radiography, intravenous urography, renal ultrasonography and/or non-contrast computed tomography scans were conducted in all patients. The success rate was defined as, patients who were stone-free or only had residual fragments of < 3 mm. Results: A total of 62 patients (43 male, 19 female), with a mean (SD) age of 39 (15.1) years, were included. The mean (SD) stone size was 23.2 (6.11) mm with a mean (SD) operative time of 58.8 (16.24) min. The stone-free rates were 90.3% and 100% after the first and second procedures, respectively. The mean (SD) hospital stay was 1.58 (0.72) days. There were minor complications (Clavien-Dindo grade I-II) in 10 (16%) patients and major complications (Clavien-Dindo III-IV), e.g. distal ureter laceration and laser injury of the ureter, in two patients. Conclusion: Same session bilateral f-URS is a successful and safe method for bilateral renal and/or ureteric stones.

    Chronic Bacterial Prostatitis in a Turkish Population: The Microbiological Etiology and Distribution
    (Aves, 2018) Arda, Ersan; Cakiroglu, Basri; Arikan, Mehmet Gurkan (Trakya author); Gozukucuk, Ramazan
    Objective: To investigate the category 2 frequency and microorganism distribution of patients diagnosed with chronic prostatitis in a Turkish population. Methods: Data of 3200 patients diagnosed with chronic prostatitis in the urology outpatient clinic between 2009 and 2014 were retrospectively reviewed. The symptom scores were calculated considering the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) according to pain (0-21 points), quality of life (0-12 points), and urinary (0-10 points) subdomains to a total score of 0-43 points. All patients were checked for symptoms, urinalysis, expressed prostatic secretion (EPS), or urine after prostatic massage (VB3) culture and PCR (Polymerase Chain Reaction) of EPS or VB3 for Chlamydia trachomatis, Ureaplasma urealyticum, Mycoplasma hominis, Mycoplasma genitalium, and Trichomonas vaginalis. Results: The mean age of the patients was calculated as 37.7 +/- 7.4 (range 22-65) years. The average of total NIH-CPSI score was determined as 9.08 (range 1-40). In 223 of 3200 patients, positive culture and/or PCR results were observed. The results were as follows: E. coli 27 (12.1%), E. faecalis 18 (8.1%), S. epidermidis 15 (6.7%), S. haemolyticus 10 (4.5%), S. aureus 5 (2.2%), S. agalactiae 4 (1.8%), Pseudomonas 3 (1.3%), C. trachomatis 24 (10.8%), U. urealyticum 95 (42.6%), M. genitalium 6 (2.7%), M. hominis 14 (6.3%), and T. vaginalis 2 (0.9%). Conclusion: In a Turkish population, category 2 patients constitute 7% of all chronic prostatitis patients. This ratio is consistent with the NIH classification of prostatitis data, but it differs etiologically with U. urealyticum, E. coli, and C. trachomatis being the most proliferated pathogens in our study.
