Predictive Value of Additional Clinical and Radiological Parameters for Discrimination of Malignancy in Bosniak 3 Cysts.

Introduction: Almost half of the cystic renal lesions are still overdiagnosed and overtreated. New clinical and radiological parameters are needed to distinguish the malignant Bosniak 3 lesions from the benign ones. We aimed to evaluate the clinical and radiological parameters that may be related to malignancy risk for Bosniak category 3 renal cysts.

Immunohistochemical evaluation of Cajal-like cells and Caveolin-1 levels at ureteropelvic junction obstruction.

Objective: To compare c-kit-positive interstitial Cajal-like cells (ICC) and Caveolin-1 protein levels as a pacemaker and signaling molecules, on ureteropelvic junction (UPJ) specimens, between two groups of pediatric patients with and without ureteropelvic junction obstruction (UPJO).

Methods: We evaluated the UPJ specimens of 45 pediatric patients operated between 2005- 2012 retrospectively. Group 1 included 37 patients who underwent dismembered pyeloplasty due to UPJO.

The Histopathologic Correlation of Bosniak 3 Cyst Subclassification.

Objective: To evaluate the histopathologic correlation of recently described subclassification of Bosniak category 3 cysts (3s and 3n).

Materials And Methods: A total of 106 patients who underwent partial/radical nephrectomy due to a complex renal cyst (≥Bosniak 3) were retrospectively reviewed. All the scans of the patients were reevaluated by 2 experienced uroradiologists.

Influence of preoperative hydronephrosis and ureteral orifice involvement in the survival of patients undergoing radical cystectomy: A retrospective comparative study.

Objective: The aim of the present study was to evaluate the influence of preoperative hydronephrosis and ureteral orifice involvement (UOI) on survival of patients undergoing radical cystectomy (RC) for bladder cancer (BC).

Material And Methods: A total of 162 patients with BC underwent RC between January 2006 and March 2017. Patients were divided into two groups for both presences of preoperative hydronephrosis and orifice involvement at final pathology.

Colonizations on biofilm layers of D-J catheters under sterile urine conditions.

Objective: To evaluate colonizations onbiofilm layers of Double J (D-J) catheters implanted forkidney stones or ureteral stones under sterile conditions.

Methods: D-J catheters implanted between January2012 and February 2014 and removed in 0-90 days,were examined in microbiology laboratory prospectively.Fifty two patients divided into three groups regardingthe duration of the D-J catheters as; 0-30 days, 31-60days, 61-90 days.

Hydronephrosis due to a Migrated Intrauterine Device into the Ureter: A Very Rare Case.

Intrauterine device (IUD) insertion is a long-acting and one of the most effective modes of reversible contraception. Complications that most commonly arise following IUD insertion are failed insertion, pain, vasovagal reactions, infection, menstrual abnormalities, and expulsion. In this paper, we present the case of a woman who experienced hydronephrosis due to the migration of IUD into the ureter after 30 years of insertion.

Methods: We retrospectively evaluated patients who had stone analysis, NCCT images, and underwent percutaneous nephrolithotomy between 2013 and 2016. Patient characteristics, stone measurements on NCCT images, and stone analysis results were evaluated.

Does leaving residual fragments after percutaneous nephrolithotomy in patients with positive stone culture and/or renal pelvic urine culture increase the risk of infectious complications?

The residual fragments in patients with preoperative and intraoperative culture positivity may serve as an infection focus. The aim of this study was to assess the importance of residual fragments for developing SIRS in patients with stone culture and/or RPUC positivity. After obtaining institutional review board approval, a total of 729 patients who undergone PCNL for renal stones were included in this study.

Endourological treatment of bilateral ureteral stones in bilateral ureteral duplication with right ureterocele.

Bilateral collecting system duplication is a very rare abnormality, including the splitting of the ureteric bud. Complete ureteral duplication with two separate openings in the urinary bladder is also extremely rare. To the best of our knowledge, we present the first case of bilateral ureteral stones in bilateral duplicated collecting system.
