OBJECTIVE To evaluate the ability of preoperative neutrophil-lymphocyte ratio (NLR) to predict pathologic upstaging and nonorgan-confined (NOC) (≥pT3) disease. METHODS AND MATERIALS After institutional review board approval, the records of consecutive patients undergoing radical cystectomy (RC) for urothelial carcinoma from 2002 to 2012 at the University(More)
PURPOSE OF REVIEW Urolithiasis is a common urological problem, often requiring efficient workup, accurate diagnosis, and treatment. The purpose of this review is to summarize the imaging modalities employed for the diagnosis of calculi and the caveats of different clinical situations. RECENT FINDINGS Noncontrast computed tomography has become the most(More)
INTRODUCTION/OBJECTIVE Robotic-assisted partial nephrectomy (RPN) offers a mean length of stay (LOS) of 2 to 3 days. The purpose of this study is to determine the impact of modifiable and nonmodifiable risk factors on hospital LOS after RPN. PATIENTS AND METHODS We retrospectively reviewed our prospectively maintained database to identify all patients(More)
OBJECTIVE To describe, categorize, and determine the outcomes of repairs of genitourinary (GU) injuries that occur during colorectal surgery. Presently, little is known regarding these injuries or the long-term outcomes of their repair. METHODS We performed a retrospective review of patients undergoing colorectal surgery between 2003 and 2013 who(More)
Male urethral "play" has been described for centuries. There are serious potential complications in this. We present a bizarre case of a variant of such play. A 49-year-old man presented with abdominal pain and incontinence. He had created a "neovagina" at the perineum for self-pleasure. The handle of a toilet brush was placed in the neovagina for(More)
OBJECTIVE Computed tomography (CT) is a common research procedure for measuring abdominal fat distribution, but little is written about the software used to analyze images. Our objective was to compare in-house and commercially available software for quantitative measurement of abdominal fat distribution. In the process, we encountered some unexpected(More)
OBJECTIVE To develop an evidence-based approach to the diagnostic workup of suspicious upper urinary tract lesions. METHODS The PubMed database was searched using the following terms with a filter for English language: "upper tract urothelial carcinoma" and "upper tract transitional cell carcinoma," along with the following corresponding terms: "cost,"(More)
OBJECTIVE To evaluate the incidence of and risk factors for a urine leak in a large multicentre, prospective database of robot-assisted partial nephrectomy (RPN). PATIENTS AND METHODS A database of 1 791 RPN from five USA centres was reviewed for urine leak as a complication of RPN. Patient and tumour characteristics were compared between patients with(More)
Is robotic partial nephrectomy (RPN) a superior operation to laparoscopic partial nephrectomy (LPN)? In the article by Choi et al [1] in this month’s issue of European Urology, a total of 23 studies with 2240 patients were evaluated and revealed that RPN has numerous superior outcomes compared with LPN. RPN was found to provide a better postoperative(More)
OBJECTIVE To review our experience with neurogenic bladder (NGB) patients who developed urinary-cutaneous fistulae (UCF). Patients with NGB can form UCF of multiple etiologies; however, little is known about the characteristics or long-term outcomes of these defects. MATERIALS AND METHODS We reviewed 21 patients with NGB who developed UCF between 1998 and(More)
