Abstract Introduction: To characterize patient reported outcomes for urinary and sexual function using International Prostate Symptom Score (IPSS) and Sexual Health Inventory for Men (SHIM) comparing intensity modulated radiation therapy (IMRT), low dose rate brachytherapy (LDR), post-prostatectomy IMRT (PPRT), and radical prostatectomy (RP).
Materials and methods: Patients treated for prostate cancer from 2001-2012 completed self-reported SHIM and IPSS surveys. Subgroups were created by baseline score. Mean change from baseline was determined at each time point for the cohort and subgroups. Statistical analysis was performed with generalized estimating equation method. Incontinence was not captured in the questionnaires.
Results: A total… More >

Abstract Introduction: Chronic scrotal content pain (CSCP) is a common condition that can be challenging to manage definitively. A cohort of patients with CSCP have referred pain from myofascial abnormalities of the pelvic floor and therefore require treatment modalities that specifically address the pelvic floor such as pelvic floor physical therapy (PFPT).
Materials and methods: Retrospective chart review of all men with a pelvic floor component of CSCP presenting to our tertiary care medical center and undergoing PFPT from 2011-2014. Patients with CSCP and pain/tightness on pelvic floor evaluation with 360° digital rectal exam (DRE) were referred to… More >

Abstract Introduction: This study investigated the polar sub-localization of prostate cancer on needle core biopsy ("polar" defined as tumor ≤ 1 mm from the tissue polar edge) as a predictor of extraprostatic extension.
Materials and methods: Histologic sections from 58 patients who underwent preoperative prostate biopsy and radical prostatectomy at the University of Kentucky from 2006 to 2013 were evaluated. Patients were retrospectively case matched based on pathologic stage (pT2 versus pT3/4) using biopsy Gleason grade and prostate-specific antigen. Histologic sections of needle core biopsies were analyzed for polar involvement. The location of polar involvement was correlated to… More >

Abstract Introduction: To systemically measure the impact of trainees' participation on the perioperative and functional outcomes after holmium laser enucleation of the prostate (HoLEP).
Materials and methods: Benign prostatic hyperplasia patients who underwent HoLEP at our department between January 2007 and January 2013 were classified based on trainee's level. Perioperative outcomes and complications were collected. Functional outcomes were assessed using the Sexual Health Inventory for Men (SHIM), International Prostate Symptom Score (IPSS), and International Continence Society-Short Form (ICSmaleSF) questionnaires. Voiding and incontinence domains of ICSmaleSF were assessed separately. Patients were divided into group 1 if no trainee participated… More >

Abstract Introduction: We sought to investigate the association of preprostatectomy magnetic resonance imaging (MRI) and surgical pathologic findings in patients with prostate cancer.
Materials and methods: All patients with prostate cancer and preprostatectomy MRI available between 2002 and 2015 were included. Age, prostate-specific antigen at diagnosis, Gleason score at biopsy, MRI technique, radiology report suggestive of prostate cancer, extraprostatic invasion and seminal vesicle involvement, lymphadenopathy and final pathology report were retrospectively reviewed. Data was analyzed for sensitivity, specificity, positive and negative predictive values of MRI findings for predicting T3 disease. Consistency of MRI findings with pathology report was… More >

Abstract Introduction: Up to 25% of men with prostate cancer who undergo radical prostatectomy will recur. In this setting, salvage radiotherapy may cure patients with local recurrence, but is unable to cure those with occult metastatic disease. The objective of this study is to examine how prostate-specific antigen (PSA) response to radiotherapy predicts subsequent disease progression and survival.
Materials and methods: Using a prospectively populated database of 3089 men who underwent open radical prostatectomy, 212 patients (7%) were identified who received early salvage radiotherapy for biochemical recurrence. The main outcome was time to disease progression after salvage radiotherapy.… 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 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 Malignant mesothelioma is an uncommon neoplasm that develops from serous surfaces, and rarely from the tunica vaginalis. Although atypical in any location, paratesticular presentation is exceedingly infrequent as only 0.3% to 1.4% of mesothelioma cases arise from the tunica vaginalis. Fewer than 300 cases have been reported with very few descriptions of long term follow up and multimodal therapy. Here we describe a patient with 2 years of follow up for metastatic mesothelioma treated with orchiectomy, chemotherapy and robot-assisted laparoscopic retroperitoneal lymph node dissection. More >

Abstract Benign prostatic hyperplasia (BPH) represents one of the most common conditions encountered in urological practice. For many years, transurethral resection of the prostate (TURP) has been considered the gold standard for surgical management of symptoms in prostates of 30 cc-80 cc. Although TURP provides excellent functional outcomes, there is significant morbidity associated with the procedure, particularly with regards to bleeding, electrolyte imbalance and sexual dysfunction. Emerging technologies aim to maintain the excellent functional results of TURP whilst decreasing the adverse events experienced by the patient.

Abstract Introduction: The aim of this study was to analyze management and outcomes of treatment in patients with acute scrotum.
Material and methods: From January 1990 until January 2015 case records of 558 patients who underwent surgery for acute scrotum were retrospectively reviewed. Mean age was 12 years old. Each patient was analyzed for following parameters: history data, localization of pain, physical examination, operating results and the results of follow up, age, etiology, and the time from initial symptoms to surgery.
Results: Scrotal explorations revealed 142 cases (25%) of spermatic cord torsion, 344 (62%) torsion of the testicular appendage,… More >
