We aimed to compare the safety and efficacy of gradual dilatation (GD) and balloon dilatation (BD) in supine percutaneous nephrolithotomy (PNL) in patients with obesity. The study was performed on 164 patients with a body mass index (BMI) ≥30 kg/m who underwent supine PNL in the Galdakao-modified Valdivia position. Sixty patients who underwent tract creation with BD were defined as Group 1, and 104 patients who underwent tract creation with GD were defined as Group 2.

Introduction: This study aimed to investigate the relationship between the International Society of Urological Pathology (ISUP) score upgrade and inflammation in transrectal ultrasound-guided prostate biopsy (TRUS-Bx) specimens.

Methods: The data of 340 patients who underwent robot-assisted radical prostatectomy were retrospectively evaluated, and two groups were formed based on the presence (Group 1, n = 168) or absence (Group 2, n = 172) of an ISUP score upgrade. Prostate characteristics, imaging findings, and inflammation on TRUS-Bx were recorded in both groups for statistical analysis.

Objectives: We aimed to investigate the common mechanisms in restless legs syndrome (RLS) and overactive bladder (OAB), the prevalence of OAB in RLS, and the effects of RLS treatment on OAB.

Methods: Sixty patients newly diagnosed with RLS and 60 healthy individuals in the control group were included in the study. The patients completed the RLS-Severity Rating Scale and were started on pramipexole for treatment.

Mini-percutaneous nephrolithotomy (MPCNL), which has a smaller tract size (14-20 Fr) than conventional percutaneous nephrolithotomy, has been shown to be safe and effective in pediatric patients with large and complex upper urinary tract stones. This study aimed to compare the efficacy and safety of MPCNL between the supine and prone positions in a pediatric population. The data of pediatric patients who underwent MPCNL at our center between January 2010 and March 2023 were retrospectively analyzed.

Purpose: This study investigates the frequency of isolated microorganisms and the antimicrobial resistant pattern of inner foreskin and smegma in prepubertal children.

Materials And Methods: This comparative cross-sectional study was conducted between March and November 2019, where 132 prepubertal boys, who were scheduled to receive religious circumcisions at our outpatient clinic, were examined. The patients were divided into the following groups based on the presence of smegma in their subpreputial space: Group I (with smegma, n=58) and Group II (without smegma, n=74).

Background/aim: We evaluate whether transrectal ultrasonography (TRUS)-guided prostate biopsy might lead to spillage of tumor cells into peripheral blood as a result of disruption of the epithelial barrier and ultimately result in metastasis.

Materials And Methods: Eighty-eight patients underwent TRUS-guided prostate needle biopsy due to prostate-specific antigen (PSA) increase or abnormal digital rectal examination at the Samsun Research and Training Hospital (Samsun, Turkey) between April 2016 and September 2018. Approximately 10 mL of whole blood was collected from patients before, 1 week after, and 1 month after biopsy.

Objective: We aimed to investigate the effects of migraine and tension-type headaches (TTH) on female sexual function.

Material And Methods: In this prospective study, sexually active females; 45 who were suffering from migraines, 47 who were TTH patients as diagnosed by a neurology clinic, and 50 who were healthy women that served as the control group were included. Sexual functions of the cases were evaluated through the Female Sexual Function Index (FSFI) with Turkish validation and the results were compared among the groups.

The aim of this study was to evaluate the structural changes in testicles of the patients with varicocele by strain elastography (SE) and to identify the relationship between semen analysis and hormone levels considering SE results. The patients were separated into two groups as varicocele and control, according to their physical examination and the scrotal colour duplex ultrasonography results. All patients underwent examination by hormonal profile, semen analysis, colour duplex ultrasonography and sonoelastography.

Abdominoscrotal hydrocele is a rare entity with unclear etiology which may be diagnosed with general examination and ultrasound imaging. During examination it may misinterpreted as acute urinary retention of the bladder (globe-like) especially if associated with hydronephrosis. It should be treated surgically.

Osteopontin (OPN) is one of the urinary proteins with an important role in stone formation. Recently, OPN Ala250 (rs1126616) polymorphism and other single nucleotide polymorphisms (SNPs) have been studied to define their role in urolithiasis. This study was conducted to examine the impact of OPN Ala250 polymorphism on the risk of stone formation and their association with serum OPN levels.

In this study we report our initial robot-assisted laparoscopic radical prostatectomy (RALRP) experience for organ-confined prostate cancer with the first 112 cases between August 2009 and January 2011. The mean age was 61 (46-76) years. Gleason scores ranged between 4 and 9, and the mean prostate volume was 38.

Objective: We present the transperitoneal and retroperitoneal approaches to laparoscopic partial nephrectomy and compare the outcomes of each technique.

Methods: Between December 2006 and March 2010, retroperitoneal laparoscopic partial nephrectomy (RLPN) was performed in 23 patients and transperitoneal laparoscopic partial nephrectomy (TLPN) in 26 patients. They were compared regarding surgical technique, operative parameters, postoperative recovery and follow-up data.

Background And Purpose: We investigated the incidence of ureteral stricture in patients treated with ureterorenoscopic pneumatic lithotripsy for distal ureteral calculi.

Patient And Methods: Between April 2006 and January 2009, 154 patients requiring ureterorenoscopic pneumatic lithotripsy for distal ureteral calculi were enrolled into the study. We evaluated the stone size, impaction of a stone, the need for ureteral orifice dilatation and the need for application of double-J stent.
