Abstract Introduction: We reviewed the consultation patterns for difficult urethral catheter placement in tertiary care hospitals and developed a treatment algorithm for this common request.
Materials and methods: We identified all urethral catheter consults obtained by urology residents at three tertiary care hospitals from October 2009 through October 2010. Only consults for inability to place urethral catheter by the referring team were included; hematuria or clot retention were excluded. Patient age, date of consultation, consulting service, prior urologic history, initial number of attempts, and final outcome were recorded.
Results: Eighty-one consults were recorded. Seventy-seven (96%) were male; the median… More >

Abstract Introduction: Audience response systems (ARS) have not been used to gauge knowledge transfer and retention in the setting of large medical conferences. In this study, we explore the utility of an ARS as an educational tool in the setting of a large urology conference.
Materials and methods: At the 2011 joint meeting of the Mid-Atlantic and New England sections of the American Urological Association, conference attendees were able to use a web-based and cell-phone accessed ARS. At the meeting, six ARS questions were asked during five point-counterpoint debate topics covering areas of prostate cancer, incontinence, pediatrics, stone… More >

Abstract Introduction: To identify factors associated with the development of chronic kidney disease (CKD) after nephrectomy and to create a clinical model to predict CKD after nephrectomy for kidney cancer for clinical use.
Materials and methods: We identified 144 patients who had normal renal function (eGFR > 60) prior to undergoing nephrectomy for kidney cancer. Selected cases occurred between 2007 and 2010 and had at least 30 days follow up. Sixty-six percent (n = 95) underwent radical nephrectomy and 62.5% (n = 90) developed CKD (stage 3 or higher) postoperatively. We used univariable analysis to screen for predictors… More >

Abstract Introduction: To examine the outcome of deferred permanent seed brachytherapy (BT) for localized low or intermediate risk prostate cancer in order to identify predictors of delayed therapy (DT).
Materials and methods: We studied 714 patients treated with BT with or without external radiotherapy. DT was defined as no treatment for > 350 days after the first biopsy with cancer. Factors influencing DT were analyzed. PSA outcome was assessed only in patients with a follow up ≥ 24 months. Patients with DT were compared to patients treated < 350 days using non-parametric tests. Multivariate analysis was performed using… More >

Abstract Introduction: Inflammation plays a key role in the development of benign prostatic hyperplasia. Prostaglandin E2 (PGE2) is an important inflammation factor found in enlarged prostatic tissue that can be the main cause of inflammatory pain. The aim of this study was to investigate whether epidural anesthesia can block the negative effects of prostaglandin mediators during prostate surgery.
Materials and methods: The study included 60 patients who underwent open prostatectomy. All patients were randomly allocated to one of two study groups. The first group received general anesthesia and the second group a combination of general and epidural anesthesia.… More >

Abstract Introduction: Proton therapy (PT) for prostate cancer is an expensive treatment with limited evidence of benefit over conventional radiotherapy. We sought to study whether online information on PT for prostate cancer was balanced and whether the website source influenced the content presented.
Materials and methods: We applied a systematic search process to identify 270 weblinks associated with PT for prostate cancer, categorized the websites by source, and filtered the results to 50 websites using predetermined criteria. We then used a customized version of the DISCERN instrument, a validated tool for assessing the quality of consumer health information,… More >

Abstract Introduction: Though the prevalence of metastatic prostate cancer is decreasing, the rate of admission from the emergency department (ED) is increasing. Little is known about the implications of metastatic site on a patient's ED course and admission.
Materials and methods: A weighted estimate of 15,367 patients with metastatic prostate cancer who presented to the ED between January 1, 2006 and December 31, 2009 was abstracted from the United States Nationwide Emergency Department Sample (NEDS). Descriptive statistics were used to elaborate patient and hospital characteristics of the metastatic prostate cancer population and logistic regression models were fitted to… More >

Abstract Introduction: Prior studies of volumetric effects of 5α-reductase inhibitors (5ARIs) on the prostate have used transrectal ultrasound which provides poor differentiation of prostatic zones. We utilized high-resolution prostate MRI to evaluate the true dynamic effects of 5ARI in men who underwent multiple MRIs.
Materials and methods: A retrospective study of patients who underwent serial 3.0 Tesla prostate MRI from 2007 to 2012 and were treated with 5ARI were studied. Nineteen patients who had a baseline MRI prior to 5ARI initiation and subsequent MRI follow up were selected. A randomly selected group of 40 patients who had not… More >
