Abstract Introduction: Traditionally, a voiding cystourethrogram (VCUG) has been obtained in patients diagnosed with multicystic dysplastic kidney (MCDK) because of published vesicoureteral reflux (VUR) rates between 10%–20%. However, with the diagnosis and treatment of low grade VUR undergoing significant changes, we questioned the utility of obtaining a VCUG in healthy patients with a MCDK. We reviewed our experience to see how many of the patients with documented VUR required surgical intervention.
Materials and methods: We performed a retrospective review of children diagnosed with unilateral MCDK from 2002 to 2012 who also underwent a VCUG.
Results: A total of 133… More >

Abstract Placement of an artificial urinary sphincter (AUS) remains the gold standard for treatment of stress urinary incontinence after radical prostatectomy. Persistent or recurrent incontinence after AUS placement can occur. Options then include cuff revision or placement of a retrourethral transobturator sling (RTS), among other alternatives. This report describes simultaneous cuff revision and placement of a RTS for management of refractory stress urinary incontinence after radical prostatectomy. This approach obviates the need for additional procedures if one approach fails. This is especially valuable for patients averse to operative intervention and those at high risk for general More >

Abstract Introduction: To inform historical trends and racial disparities in prostate cancer across time and geography.
Materials and methods: Data from 58 autopsy studies of latent prostate cancer from 1898–2013 were identified and analyzed accounting for histopathological methods, which may have varied over time.
Results: Prostate cancer is most prevalent in African descent men, less prevalent in European descent men, and least prevalent in Asian descent men. Fifty percent of Asian men have latent prostate tumors by 90. This 50% prevalence is reached by age 80 in Caucasians, and by age 60 in African descent men. While men are… More >

Abstract Introduction: The role of laparoscopic radical nephrectomy (LRN) in the management of very large renal masses has yet to be determined. Moreover, no studies have considered the total size of the specimen removed. We report our experience managing renal masses ≥ 10 cm with transperitoneal LRN.
Materials and methods: We retrospectively reviewed cases of LRN performed in the context of renal masses from 2006 to 2012 at our institution. LRNs were divided into two groups; tumors 10 cm or larger (n = 24) and tumors smaller than 10 cm (n = 124). Patient demographics, tumor characteristics, operative… More >

Abstract Introduction: To identify and assess predictive factors for positive surgical margins (PSM) in patients undergoing radical prostatectomy (RP).
Materials and methods: An Institution Review Board (IRB) approved retrospective review of 1751 patients that underwent RP from March 2000 to June 2013 was performed. Identified were 1740 patients whom had not received neoadjuvant therapy; these were used for the purpose of this analysis. Univariate and multivariate analysis were performed to determine factors associated with and predictive of PSMs, divided into preoperative and pathological. Variables analyzed include age, body mass index (BMI), race, surgeon, surgical modality, pathologic T-stage and… More >

Abstract Introduction: In obstructive azoospermia, choosing a sperm retrieval method for intracytoplasmic sperm injection (ICSI) depends on the preference and expertise of both the urologist and the reproductive endocrinologist. Generally, a percutaneous epididymal sperm aspiration (PESA) is attempted first. Not uncommonly, multiple PESA's are necessary. This study utilizes a rat model to provide an understanding of sperm parameter and histological changes resulting from repetitive PESA procedures.
Materials and methods: A cohort of 30 male Wistar rats of reproductive age (68-73 days) was divided into three groups of 10 (G1-G3). All three groups underwent a left epididymal head… More >

Abstract Introduction: We compared a single surgeon, single-institution experience with the Wolf Ultrasonic Model #2167.05 (Richard Wolf Medical Instruments Co., Vernon Hills, IL, USA), Lithoclast Ultra (Boston Scientific, Natick, MA, USA), and CyberWand (Gyrus/ACMI, Southborough, MA, USA) lithotripters for percutaneous nephrolithotomy (PCNL). We assessed each lithotripter's performance and durability.
Materials and methods: We conducted a retrospective chart review on 70 sequential PCNLs. Treatments were split into three cohorts based on the type of lithotripter used: Wolf (August 2003 to February 2004), Lithoclast (March 2004 to November 2008), or CyberWand (December 2008 to October 2009). Operative time, repeat… More >

Abstract Introduction: High submuscular (HSM) inflatable penile prosthesis (IPP) reservoir insertion is a new technique that involves placing the reservoir high beneath the muscles of the abdominal wall. We queried a variety of surgeons to assess their impressions of how HSM reservoir placement compares with traditional space of Retzius (SOR) placement.
Materials and methods: A nationwide group of urologists trained in HSM reservoir placement was surveyed to assess preferences and concerns compared to SOR placement. Using a Likert scale survey, we compared HSM to traditional SOR placement with regard to ease of implementation, surgical preference, and patient safety.… More >
