Abstract Introduction: To determine whether quantifying the proximity of positive prostate biopsy cores to the capsular edge may aid in identifying patients at risk for extracapsular extension (ECE) at the time of radical prostatectomy (RP).
Materials and methods: We reviewed a single-surgeon experience of 429 systematic transrectal prostate biopsies from 2010-2014. Marking ink was applied to the capsular edge ex vivo following specimen acquisition, and the proximity of cancer to the stained capsular edge was measured. Primary outcome was ECE at RP. Demographics, PSA, DRE findings, Gleason score, core location and involvement, and RP pathology were recorded. Predictors… More >

Abstract Introduction: Neurovascular bundle (NVB) preservation during robot-assisted radical prostatectomy (RARP) directly affects patient functional outcomes. Despite careful surgical planning, many NVB preservation techniques are changed intraoperatively from their preoperative plan. Our objective was to identify risk factors predicting intraoperative change in NVB preservation technique during RARP.
Materials and methods: Prospective data from 578 RARPs performed by a single surgeon between 2010 and 2017 at a tertiary care center. Side-specific NVB preservation technique was planned preoperatively. Surgical techniques were either complete nerve sparing (CNS), or incomplete nerve sparing (INS). Variables included age, tumor grade, prostate volume, number of… More >

Abstract Introduction: To evaluate the reasons leading to an extended hospital stay (EHS) in patients undergoing radical cystectomy (RC) with postoperative enhanced recovery after surgery (ERAS) protocol.
Materials and methods: A total of 509 patients underwent RC and urinary diversion with ERAS between May 2012 and March 2017. The protocol includes no bowel preparation, early feeding, predominantly non-narcotic pain control, and μ opioid antagonists. Non-consenting/lost to follow-up patients, and those with non-urothelial carcinoma were excluded. We defined EHS as ≥ 5 postoperative days and compared the cohort to those with a length of stay (LOS) of ≤ 4… More >

Abstract Introduction: To assess whether urologists are able to accurately estimate the cost of commonly used endourologic disposable devices.
Materials and methods: An anonymous questionnaire was presented to resident and attending urologists in one academic healthcare system. Respondents estimated the cost of 15 disposable devices commonly used in ureteroscopy. Twenty-five surgeons (9 residents and 16 attending urologists) participated, for a response rate of 96.2%. Respondents’ cost estimates were compared to actual institutional costs and considered accurate if the absolute percentage error was within 20%. Additional information obtained included: years in practice, participation in purchasing activities, practice setting, number… More >

Abstract Introduction: The optimal patient positioning for percutaneous nephrolithotomy (PCNL) based on the complexity of stone burden is not yet defined. Thus, we aimed to evaluate the intraoperative parameters, effectiveness and complications of patients undergoing PCNL between the endoscopic-guided prone split-leg PCNL (ePSL) and the supine PCNL by stratifying patients according to Guy’s stone score (GSS).
Materials and methods: A retrospective chart review was conducted of patients undergoing PCNL at two high-volume tertiary referral centers. At one center, patients underwent PCNL using the ePSL technique, while at the second center, patients underwent PCNL in supine. Patient demographics and… More >

Abstract Introduction: 2-octylcyanoacrylate (OC) has been shown to be a viable option for usage following standard circumcision, but data on its utilization following hypospadias repair is limited. Both OC and a standard waterproof transparent dressing (WD) are used following hypospadias repair at our children’s hospital. Our hypothesis is that patients with distal hypospadias repair using OC for surgical dressing have similar outcomes as compared to patients with WD.
Materials and methods: A retrospective study was performed evaluating all patients with distal hypospadias repair during a 2-year period. OC was primarily used by one of the three physicians in… More >

Abstract Corynebacterium urealyticum is an organism associated with a rare chronic urinary tract infection, which can lead to calcification of the urinary tract and promote rapid lithogenesis. This case illustrates the serious complications that can arise from chronic infection with C. urealyticum, which include rapid progression of luminal and parenchymal urinary tract calcification and concomitant renal failure. This case and a review of the literature demonstrate the need for an increased awareness of this organism with early identification, aggressive management, and test of cure that may help avoid the sequela of these infections.

Abstract Primary spindle cell sarcoma of the prostate is exceedingly rare and accounts for 0.1% of all prostatic cancers. Typically, the disease course is rapid and portends a short and dismal prognosis. We report a case of prostatic stromal sarcoma (PSS) which likely lay dormant for several years after a transurethral resection of the prostate. This case is unique in that this cancer did not display the rapid growth of PSS in prior reports. Our patient received a cystoprostatectomy and an ileal conduit. This article describes a rare presentation of a rare tumor and a brief More >
