Objective: Retropubic radical prostatectomy (RRP) is still widely used in clinical practice in localized prostate cancer because of its high oncological success. The aim of this study was to define the continence status in patients where rhabdosphincter was included in the vesicourethral anastomosis.

Materials And Methods: Between November 2004 and September 2010, 90 cases who underwent RRP by the same surgeon in our clinic were taken into the study.

Aims: We validated a Turkish language version of the urethral stricture surgery specific patient-reported outcome measure (USS-PROM) in men undergoing anterior urethroplasty. We also investigated changes in erectile function (EF) and quality of life (QoL) due to oral mucosa graft (OMG) harvesting.

Methods: The USS-PROM captures lower urinary tract symptoms (LUTS), health related QoL (HRQoL) with EQ-5D visual analogue scale (EQ-VAS).

Objective: To evaluate the functional outcomes of ventral inlay labia minora graft urethroplasty (VILGU) for the management of female urethral strictures.

Methods: Data of 7 consecutive women treated with VILGU between 2011 and 2013 were reviewed. Two patients had cystostomy tubes at repair, and 5 had undergone previous urethral dilations and urethrotomies.

Background And Purpose: To compare the advantages of flexible and rigid cystoscopy-assisted ureteral catheter placement before prone percutaneous nephrolithotomy (PCNL).

Patients And Methods: From March to September 2012, a total of 80 patients with kidney stones underwent PCNL by the same surgical team. The patients were randomly assigned into one of the groups according to the technique used for ureteral catheter insertion: Flexible cystoscopy (group 1, n=40) or rigid cystoscopy (group 2, n=40).

Treatment of kidney stones in pelvic ectopic kidneys of children is a challenging procedure for urologists. Herein we report a case of laparoscopy-assisted "microperc" in a 3-year-old girl with a stone in her pelvic ectopic kidney. This micro-optical system is helpful in confirming the percutaneous access and provides the possibility of fragmenting the stone without the necessity of dilating the tract.

Purpose: We present our initial experience with microperc in patients with moderate-size renal calculi.

Patients And Methods: A retrospective analysis of 30 patients (male 14, female 16) with moderate-size (1-3 cm) kidney stones who underwent microperc between August 2011 and July 2012 was performed. The demographic values, perioperative and postoperative measures including age, stone size and location, body mass index, operative and fluoroscopy time, hemoglobin decrease, success and complication rates were prospectively recorded into a patient entry system.

Objective: To present the feasibility and safety of fluoro-less endoscopic treatment of ureteral stones to diminish radiation exposure of the patient and operating team, and to determine circumstances where a fluoroscopic imaging is mandatory.

Methods: Between 2010 and 2011, 93 patients with ureteral calculi who underwent ureteroscopic treatment by experienced urologists were retrospectively evaluated. Manipulations, such as guidewire, ureteral stent insertion, and balloon dilatation were performed with visual and tactile cues.

Purpose Of Review: This review is aimed to provide an update on the surgical techniques and complications of sacrocolpopexy procedures, and determine the role of minimally invasive techniques based on the most recent evidence.

Recent Findings: The minimally invasive laparoscopic and robot-assisted alternatives to open abdominal sacrocolpopexy offer faster recovery, less complications and better cosmesis. However, this is suggested predominantly by retrospective comparative studies and no high-level evidence is available to date.

Objective: To report our results with 1-stage reconstruction in short distal urethral strictures using circular buccal mucosa graft (cBMG).

Methods: The data of 19 patients (median age 41.8 years, range 25-58) operated between 2001 and 2010 were reviewed.

Background And Purpose: Percutaneous nephrolithotomy (PCNL) is regarded as the gold standard for the treatment of patients with renal stones larger than 2 cm in diameter. Creating a percutaneous renal access is the initial and probably the most important step in performing a PCNL. Two primary methods of obtaining proper percutaneous renal access under fluoroscopic guidance are described: The "triangulation" and the "eye of the needle" techniques.

Primary renal mucinous cystadenocarcinoma is a very rare lesion of kidney which originates from the metaplasia of the renal pelvic uroepithelium. Only one case with primary mucinous cystadenocarcinoma has been reported in the English literature. We report second case of mucinous cystadenocarcinoma which was radiologically classified as type-IIF Bosniak cyst in peripheral localization.

A rectovesical fistula (RVF) is an uncommon complication of urooncologic surgery. Although several RVFs have been reported, our case is the first reported RVF in the literature that iatrogenically occurred after transurethral resection of the bladder. A single-stage primary repair with omental flap interposition without a colostomy was successfully performed because of the persistence of the fistula during followup.

Penile fracture is a remarkable but under reported urologic injury. Coitus and penile manipulations are common predisposing factors. Rupture of the superficial vein of penis is an uncommon situation that makes differential diagnosis with other penile lesions.

Objectives: To report our experience with urethroplasty in women with urethral stricture and discuss the therapeutic considerations and outcomes of various flap- and graft-based techniques.

Methods: A total of 17 patients with mid to distal urethral stricture (urethral caliber <14F, maximal urinary flow rate <12 mL/s, and detrusor pressure >20 cm H(2)O during voiding) underwent urethroplasty from 2004 to 2010. Of the 17 patients, 7 had undergone previous instrumentation and 10 were repaired primarily.

Introduction And Hypothesis: Abdominal sacrocolpopexy is the gold standard for advanced uterovaginal/cuff prolapse repair; however, early and late bowel complications are of concern. We report our experience with extraperitoneal sacrocolpopexy (ESCP).

Methods: Twenty-three patients who underwent ESCP between 2007 and 2010 were analyzed in this retrospective cohort study.

We report a 75-year-old female with a primary urethral malignant melanoma. Amass protruding from inside the urethra was detected on physical examination. Abdominopelvic magnetic resonance imaging revealed a mass extending from the urethra with dimensions of 4x2 cm, and periurethral heterogenous fatty planes consistent with infiltration.

Purpose: Standard surgical procedures for hydrocele may cause postoperative discomfort, temporary limitation of normal activities and complications, such as hematoma, infection, persistent swelling, chronic pain and decreased fertility. We describe a new technique in an effort to decrease these complications.

Materials And Methods: Between April 2004 and December 2006, 21 patients underwent hydrocelectomy, which was bilateral in 1.

Purpose: Reconstruction of post-prostatectomy strictures involving the fossa navicularis and external urethral meatus following benign prostatic hyperplasia treatment is challenging in terms of creating a functional and cosmetically appealing penis. We reviewed our results with the use of ventral transverse island fasciocutaneous penile flap in the reconstruction of these strictures.

Materials And Methods: Between 1997 and 2007 a total of 26 men (mean age 59 years, range 49 to 76) with post-prostatectomy distal urethral strictures underwent urethral reconstruction with a ventral transverse island fasciocutaneous penile flap.
