Abstract Introduction: Urinary fistulae develop as abnormal connections between the gastrointestinal (GI) and genitourinary (GU) tracts, and occur in multiple disease processes including diverticulitis, malignancy, and Crohn’s disease. Crohn’s disease is now the most common cause of fistula formation between the ileum and bladder and the third most common cause of fistulae between the colon and the bladder. Few articles provide a comprehensive review of this process.
Materials and methods: We performed a PubMed search using such terms as “fistula” and “Crohn’s disease” and/or “enterovesical fistula.” We reviewed references from selected papers and relevant articles were used for… More >

Abstract The prestigious Jackson Hole Seminars (JHS) successfully gathered several world leaders in academic urology and urologists in private practice for a unique scientific experience in Wyoming, USA. Unfortunately, this year Dr. Ralph Hopkins’ seat was empty but his spirit continue to be the driving force for the meeting’s excellence and friendship. The JHS has pioneered the concept of a Critique Panel comprised of previous speakers that would discuss in depth the presentations of the faculty chosen by the scientific board of the JHS. The 2014 JHS featured Dr. Fernando J. Kim, the President of JHS, More >

Abstract Introduction: Clean intermittent catheterization (CIC) theoretically reduces incontinence, urinary tract infections (UTIs) and lower urinary tract symptoms (LUTS) in the face of poor emptying. It is unclear whether all patients realize these benefits or if CIC is only helpful for some.
Materials and methods: A retrospective review of 321 patients all of whom underwent urodynamic study prior to starting CIC for impaired emptying. Success was considered to be no incontinence, no UTIs, and no LUTS while performing CIC. Patients who did not meet these criteria or who stopped CIC for whatever reason were classified as failures.

Abstract Introduction: To evaluate the clinical phenotypes of patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) using a web based online tool and to compare these clinical features with patients evaluated in a tertiary referral clinic.
Materials and methods: Data was collected from 720 men who gave complete online responses on a website which determines the UPOINT clinical phenotype in CP/CPPS and measures symptom severity with the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI). This was compared to phenotype and symptom severity of 220 patients evaluated in person at a tertiary referral clinic.
Results: The web-based cohort… More >

Abstract Introduction: Penile cancer is a rare malignancy, and few guidelines are available to define treatment paradigms. For greater understanding of the natural history of surgically treated penile cancer, we analyzed the experience at our institution.
Materials and methods: Using an institutional database, we identified 127 patients treated for squamous cell carcinoma of the penis from 1995-2011. Cancer-specific survival (CSS) was calculated using the Kaplan-Meier method. Survival data were compared using the log-rank test. The difference in risk of cancer-specific death by lymph node status and histological grade was determined by univariate Cox regression analysis.
Results: Five… More >

Abstract Introduction: Major kidney stones have traditionally been treated with percutaneous nephrolithotomy. However, retrograde intrarenal surgery (RIRS), which until a few years ago was considered inappropriate for this purpose, is becoming a viable, attractive alternative. The aim of the current study was to assess the efficacy and safety of RIRS combined with holmium laser lithotripsy for the treatment of stones >2 cm in diameter in a large series of patients, reporting complications according to the Clavien-Dindo classification.
Materials and methods: By retrospective analysis, we identified a total of 162 patients who were affected by stones greater than… More >

Abstract Introduction: We assessed the efficacy of onabotulinumtoxinA (Botox, Allergan Inc., Irvine, CA, USA) in patients with refractory overactive bladder (OAB) after treatment for benign prostatic hyperplasia (BPH).
Materials and methods: This was a two-center, randomized, double-blinded pilot study conducted in patients with OAB secondary to bladder outlet obstruction (BOO), refractory to anticholinergic medication and persistent for greater than 3 months after surgical intervention to relieve obstruction, with an International Prostate Symptom Score (IPSS) >12. Patients were randomized in 1:1 fashion to either 200 units of onabotulinumtoxinA versus placebo. Fifteen patients received onabotulinumtoxinA versus 13 who received… More >

Abstract Introduction: Radical cystectomy is associated with significant morbidity and cost, with rates of gastrointestinal complications as high as 30%. Alvimopan is a mu opioid receptor antagonist that has been shown in randomized-control trials to accelerate gastrointestinal recovery in patients undergoing bowel resection with primary anastamosis. We report our experience with gastrointestinal recovery for patients undergoing cystectomy with urinary diversion treated with alvimopan and cost benefit associated.
Materials and methods: Between January 2008 and October 2012, 80 patients underwent radical cystectomy with urinary diversion at two institutions. Forty-two patients in our study did not receive alvimopan preoperatively.… More >

Abstract Introduction: Involvement of the prostatic urethra by bladder cancer directly impacts prognosis, risk of urethral recurrence, and timing of radical cystectomy (RC); it also affects the type of urinary diversion chosen. Both cold cup biopsies and transurethral (TUR) loop biopsies have been used to evaluate the status of the prostatic urethra. We report our 20 year experience with preoperative and intraoperative prostatic urethral biopsies to determine relative efficacy and associated treatment implications.
Materials and methods: The Columbia University urologic oncology database was reviewed and yielded 234 men who underwent preoperative endoscopic biopsies of the prostatic urethra… More >

Abstract Introduction: To provide an effective form of birth control, men may choose a reversible or permanent form of contraception. Vasectomy is presently offered as a permanent option for male contraception. We have had patients who were interested in vasectomy and reversal as a temporary birth control option. The purpose of this paper is to determine if vasectomy should be offered for selected couples as a temporary form of contraception and under which circumstances.
Materials and methods: A literature review was conducted to determine the available reversible contraceptive options, risks, failure rates and contraindications to each, and… More >

Abstract Introduction: Since its first description in 1994, tubularized incised plate (TIP) technique has become the most commonly performed hypospadias procedure and involves incision of the urethral plate with subsequent tubularization. Glans wings are then developed to cover the neourethra, thereby creating a cosmetically appealing repair. In some distal hypospadias cases, mobilization and approximation of glans wings is sufficient to create a normal appearing urethral meatus.
Materials and methods: A retrospective chart review of all pediatric urology patients who underwent hypospadias repair by a single surgeon at the University of Kentucky between July 1, 2010 and April… More >

Abstract Artificial urinary sphincter (AUS) erosion often involve the urethral cuff and is managed by complete or partial device removal. Abdominal wall erosion of AUS tubing has not been previously reported and its management is unknown. We report tube erosion (TE) of AUS successfully managed without device explant. An 81-year-old male with AUS for post-prostatectomy incontinence presented with TE at the site of inguinal incision without signs or symptoms of infection. The exposed tube was reduced and wound was closed after copious antibiotic solution irrigation. No complications were noted at 2 month follow up. AUS-TE can More >

Abstract Renal lymphangiomatosis is a disease characterized by abnormal formation of perirenal lymphatic vessels that fail to communicate with other retroperitoneal lymphatics; as a result, perirenal lymphatics dilate and form cysts. While typically an asymptomatic incidental finding, renal lymphangiomatosis rarely presents as flank or abdominal pain, ascites, impaired renal function, hypertension, hematuria, or proteinuria. Here we present the first known case of renal lymphangiomatosis found to spontaneously resolve following cardiac transplantation. More >

Abstract Prostate cryoablation (PCry) is a well-established minimally invasive therapy for the treatment of prostate cancer. Unfortunately, PCry still carries the stigma of a high rate recto-urethral fistula procedure but with the advent of argon/helium gas technology, urethral warmer and high quality transrectal ultrasound imaging, complications decreased and efficacy increased. The Denver Health Medical Center’s technique in prostate cryoablation is described as follows. More >
