Aim: To assess the efficacy and safety of two different techniques (Percutaneous nephrolithotomy (PNL) vs Retrograde intrarenal surgery (RIRS)) in the management of stones in patients with horseshoe kidneys (HSK).

Patients And Methods: Departmental files of 88 cases with radiopaque kidney stones in horseshoe kidneys undergoing two different approaches (PNL vs RIRS) were evaluated with respect to the success and complication rates of in a retrospective manner. In addition to the factors related with the procedures (success and complication rates, additional procedures), patient and stone characteristics were all well evaluated.

Objectives: In this study, we aimed to evaluate ciprofloxacin resistance and the presence of extended-spectrum beta-lactamase producing organisms (ESBLs) in the population of patients with indication to undergo prostate biopsy. Our additional aim was to compare the targeted antibiotic prophylaxis and sepsis rates after transrectal ultrasound guided prostate biopsy in patients who received routine ciprofloxacin prophylaxis and to evaluate the predictive factors of antibiotic resistance.

Methods: Between September 2012 and January 2014, 300 patients were randomized to two groups.

Lower pole calyceal stones (LPS) represent lower spontaneous passage rates and, therefore, require several interventional treatment approaches. The aim of this survey study was to investigate the attitudes of the urology practitioners and the factors affecting their decision making in the management of small asymptomatic LPS. A total of 149 urologists participated to the study via email through the internet-based website.

Erectile dysfunction (ED) and urinary incontinence after bilateral nerve-sparing radical prostatectomy (BNSRP) still remain major causes of morbidity. Phosphodiesterase type 5 inhibitors (PDE5-Is) have a role in the treatment of ED after BNSRP. Several studies in patients with ED and lower urinary tract symptoms demonstrated that PDE5-Is could improve both erectile function and urinary symptoms.

The aim of the study is to evaluate the efficacy and safety of retrograde intrarenal surgery (RIRS) to treat renal stones in preschool age (<7 years) children. From September 2005 to May 2013, a total of 65 children (31 boys and 34 girls) with 72 renal stones were treated using RIRS. Patients were considered stone-free when the absence of residual fragments was observed on imaging studies.

The aim of this study was to investigate the effectiveness and reliability of the micro-percutaneous nephrolithotomy (PNL) method for the management of kidney stones. We performed a retrospective analysis of 136 patients (140 renal units) who underwent micro-PNL for renal stones between September 2011 and February 2013 in four referral hospitals in Turkey. The selection of treatment modality was primarily based on factors such as stone size and location.

Introduction: The correlation between erectile dysfunction (ED) and coronary artery disease has been emphasized and ED has been recognized as a potential independent risk factor and/or predictor of coronary artery disease (CAD). We evaluated the association between the number of occluded coronary arteries in myocardial infarction (MI) patients with the severity of ED, and investigated the influence of related risk factors in our study group.

Materials And Methods: 183 male patients who underwent coronary angiography because of acute MI from November 2009 to May 2011 were included.

Background And Objectives: The objectives of this study were to investigate the effectiveness of the applied laparoscopic urology course using a validated checklist and to determine any differences in laparoscopic skills achieved by the participants at the end of the course period based on whether they began their training in a dry or wet laboratory.

Methods: To facilitate the mastering of challenging laparoscopic skills by urologists, a unique 3-day mini-training program was established at the Gulhane Military Academy of Medicine, Surgical Research Center, Ankara, Turkey. Only 30 trainees were accepted in each course, and they were divided into 3 subgroups.

Purpose: The aim of the study was to evaluate the efficacy and safety of bilateral single-session retrograde intrarenal surgery in the treatment of bilateral renal stones.

Materials And Methods: From December 2008 to February 2012, 42 patients who had undergone bilateral single-session retrograde intrarenal surgery (RIRS) and laser lithotripsy were included in the study. The procedures were performed in the lithotomy position on an endoscopy table under general anesthesia, beginning on the side in which the stone size was smaller.
