Abstract Introduction: To evaluate erectile function among men who had undergone laparoscopic radical prostatectomy and received postoperative medical therapy for erectile dysfunction.
Materials and methods: We performed a prospective study in men who underwent laparoscopic radical prostatectomy between September 2003 and November 2005 at our center and who received penile rehabilitation after surgery. All patients had antegrade interfascial dissection. They received 10 mg tadalafil on the fifth postoperative day and continued to receive it every other day, regardless of erectile function. Intracavernous injection of alprostadil was initiated at 3 or 6 months depending on response to treatment with… More >

Abstract Introduction: The effect of gender on complications after surgery is controversial. We examine the effect of gender on five short term nephrectomy outcomes.
Materials and methods: Within the Health Care Utilization Project, Nationwide Inpatient Sample (NIS) we focused on nephrectomies performed within the most contemporary years (1998-2007). We tested the rates of blood transfusions, extended length of stay, in-hospital mortality, as well as intraoperative and postoperative complications, stratified according to gender. Multivariable logistic regression analyses fitted with general estimation equations for clustering among hospitals further adjusted for confounding factors. Separate multivariable analyses were performed for open radical… More >

Abstract Introduction: Bladder cancer diagnosis and surveillance is costly and frequent. Urinary cytology is used with cystoscopy in the diagnosis and surveillance of bladder cancer, with little evidence to support this practice. Nuclear Matrix Protein-22 (NMP-22) is a marker of urothelial cell death and is elevated in the urine of patients with bladder cancer. Our study compares the performance of NMP-22, urinary cytology, and office cystoscopy when utilized in a Veteran Affairs urology practice over a 1-year period.
Materials and methods: A total of 391 consecutive office cystoscopy procedures performed over 1 year were included in the study.… More >

Abstract Introduction: The emergency department (ED) is a common setting for evaluation of patients with urolithiasis based on acute symptoms and a propensity for recurrent disease. We sought to characterize practice patterns in the emergency treatment of stone disease, and to identify potential disparities in care based on non-medical factors.
Materials and methods: We performed a cross-sectional analysis of ED visits using the National Hospital Ambulatory Medical Care Survey from 2005-2009. Visits with a diagnosis of urolithiasis were identified. The associations between patient, provider, and institutional characteristics were analyzed with regard to timing of clinical assessment, use of… More >

Abstract Introduction: To compare the safety and efficacy of multiple-tract percutaneous nephrolithotomy (PCNL) with single-tract PCNL for complex renal stones.
Materials and methods: A total of 109 consecutive PCNL procedures for unilateral complex renal calculi (staghorn or complex caliceal calculi) were performed at our institution. Thirty patients received multiple-tract PCNL and 79 patients underwent single-tract PCNL. The two groups had comparable demographic data, except for a smaller stone burden and fewer complete staghorn calculi in those undergoing single-tract PCNL. Variables of interest included operative time, blood loss, change in serum creatinine, transfusion rates, length of hospital stay, stone… More >

Abstract Introduction: To determine the accuracy of a 12-core biopsy protocol in assessing the location of prostate tumors within radical prostatectomy (RP) specimens.
Materials and methods: A consecutive series of patients with T1c stage prostate cancer who had undergone 12 ultrasound-guided prostate biopsies prior to RP was considered. The locations of the biopsies from prostate gland mapping were compared with the locations of tumor tissues obtained after analysis of the prostate specimens.
Results: Overall, 78 patients (27.4%) were included. The median PSA level was 6 ng/mL. The median prostate weight was 45 g (range 22 to 102). Overall, 936… More >

Abstract Introduction: Most patients survive many years following external beam radiotherapy (RT) for nonmetastatic prostate cancer and are therefore at risk for late treatment sequelae. The relationships between RT dose, treatment technique, and late toxicity rates are incompletely understood. Here we perform a meta-analysis and systematic review to characterize those effects.
Materials and methods: We performed a review of published series that report late gastrointestinal (GI) and genitourinary (GU) toxicity rates following definitive RT for prostate cancer using the RTOG Late Radiation Morbidity Scoring Schema. Univariate analyses were performed to test RT technique, RT dose, pelvic irradiation, and… More >

Abstract Introduction: The prevalence of nocturnal enuresis (NE) in pediatric populations varies between 1% to 20%. The aim of this study was to determine the prevalence of NE in schoolchildren living in Tekirdag, a city in Western Turkey.
Materials and methods: We distributed a questionnaire to 11324 schoolchildren aged 7 to 14 years who were living in Tekirdag. The questionnaires were filled in by the children's parents. The main study endpoints were the prevalence of NE, and its association with sociodemographic factors of the children and their parents.
Results: The results from 9210 children (81.4%) who returned fully completed… More >

Abstract Paraganglioma of the urinary bladder is a rare tumor that often presents with hypertensive crisis during micturition. We herein present the unusual case of a 45-year-old female with metastatic paraganglioma treated with robotic-assisted partial cystectomy and pelvic lymphadenectomy. We review the literature regarding the evaluation and management of paraganglioma of the bladder. More >

Abstract Clear-cell renal cell carcinoma (RCC) is a common urological tumor known for its potential to metastasize. Common sites of metastasis include the lungs, lymph nodes, liver and bones but rare sites of metastasis are described. Gallbladder metastasis from RCC is very rare and occurs mostly in men. It is admitted that most cases are asymptomatic. Cholecystectomy has been performed as the treatment for solitary lesion. We describe a case of RCC metastasis diagnosed after lithiasic pancreatitis in a 68-year-old male. To our knowledge, this is the first case of a metachronous RCC metastasis to the More >

Abstract Penile cancer is a rare cutaneous malignancy that frequently spreads to the regional inguinal lymph nodes with a prolonged locoregional phase. An inguinal lymph node dissection may be both diagnostic and therapeutic, even in the setting of advanced disease. Despite its proven oncologic importance and efficacy, an inguinal lymphadenectomy remains underutilized, even with the publication of guidelines advocating its use. Failure to apply this modality is most likely due to the significant morbidity associated with a traditional open approach, including flap necrosis, wound infection and debilitating lymphedema.
