Abstract Paratesticular sarcomas are a rare entity and provide a unique clinical challenge due to their slow growing, often painless natural course. Adding to this challenge is the complex anatomy of the scrotum that allows these masses to mimic other conditions, including inguinal hernia, cysts, or fluid collections. We report such a case and our approach to an 83-year-old male with dedifferentiated liposarcoma of the spermatic cord with a history of inguinal hernia. In doing so, we highlight the need for thorough evaluation of scrotal masses and the management of these rare, though well-described, tumors. More >

Abstract Keratinizing desquamative squamous metaplasia (KDSM) in the renal pelvis is a rare condition with unclear malignant potential. Recent reports suggest it is likely benign and favor endoscopic treatment approaches. Medical record review was completed on two cases at our center to obtain history, physical examination, radiographic findings, and management. A literature review was completed to identify all published cases of KDSM. Both patients at our center suffered recurrent urolithiasis, hypothesized to be secondary to KDSM. Both were managed with a percutaneous approach to ensure complete stone and KDSM plaque removal. Our cases highlight that percutaneous More >

Abstract Introduction: Bladder neck contractures (BNC) are an uncommon complication following radical prostatectomy. Occasionally, BNCs can be refractory to endoscopic approaches. We describe the effectiveness of a novel robotic-assisted laparoscopic catheterizable bladder augment in treating recalcitrant BNCs.
Materials and methods: Patients undergoing robotic-assisted radical prostatectomy (RALP) between 2004-2014 who developed a postoperative BNC were identified. We documented our experience with robotic-assisted laparoscopic catheterizable bladder augment for recalcitrant BNCs. Total operative time, robotic time, estimated surgical blood, length of hospital stay, serum creatinine, complications, and postoperative course/upper tract imaging were recorded.
Results: Thirty-six of 2002 RALP patients (1.8%) experienced a… More >

Abstract Introduction: To evaluate the ability of endorectal coil (e-coil) magnetic resonance imaging (MRI) to identify early prostatic fossa recurrence after radical prostatectomy.
Materials and methods: We identified 187 patients from 2005–2011 who underwent e-coil MRI with dynamic gadolinium-contrast enhancement followed by transrectal ultrasound (TRUS) guided prostatic fossa biopsy for possible local prostate cancer recurrence. For analysis, local recurrence was defined as a negative evaluation for distant metastatic disease with a positive prostatic fossa biopsy, decreased prostate-specific antigen (PSA) following salvage radiation therapy, or increased lesion size on serial imaging.
Results: Local recurrence was identified in 132 patients, with… More >

Abstract Introduction: Urinary tract infections (UTIs) are the most common infections affecting women, and often recur. Lactobacillus probiotics could potentially replace low dose, long term antibiotics as a safer prophylactic for recurrent UTI (rUTI). This systematic review and meta-analysis was performed to compile the results of existing randomized clinical trials (RCTs) to determine the efficacy of probiotic Lactobacillus species in preventing rUTI.
Materials and methods: MEDLINE and EMBASE were searched from inception to July 2012 for RCTs using a Lactobacillus prophylactic against rUTI in premenopausal adult women. A random-effects model meta-analysis was performed using a pooled risk ratio,… More >

Abstract Introduction: Partial nephrectomy has a 3%-4% incidence of local treatment failure. This study is to present a series of percutaneous cryoablation for locally recurrent renal cell carcinoma after partial nephrectomy.
Materials and methods: Five consecutive patients were referred to our quaternary center’s multidisciplinary Small Renal Mass (SRM) Center for assessment after failure of partial nephrectomy. Tumor size and location was noted. CT-guided cryoablation was performed using an argon/helium-based system (Healthtronics, Austin, Texas, USA). Patients were admitted overnight for observation. Patients were followed with serial imaging, laboratory tests and examination at our SRM Center. Tumor size, location, and… More >

Abstract Introduction: External beam radiotherapy (EBRT) is widely utilized as primary therapy for clinically localized prostate cancer. For patients who develop locally recurrent disease after EBRT, local salvage therapy may be indicated. The primary modalities for local salvage treatment in this setting include radical prostatectomy, cryotherapy, and brachytherapy. To date, there is little data describing outcomes and toxicity associated with each of these salvage modalities.
Materials and methods: A review of the literature was performed to identify studies of local salvage therapy for patients who had failed primary EBRT for localized prostate cancer. We focused on prospective trials… More >
