Abstract Introduction: To evaluate erectile function recovery following robotic-assisted radical prostatectomy (RARP) according to preoperative sexual health inventory for men (SHIM) score stratification.
Materials and methods: We prospectively collected data on 250 consecutive patients who underwent RARP by a single surgeon between October 2006 and October 2012. Thirty-six patients were excluded because of lack of preoperative SHIM score. All patients had a minimum follow up of 2 years. Patients were divided into four groups according to their preoperative SHIM score: group 1 with normal potency (SHIM 22-25), group 2 with mild ED (SHIM 17-21), group 3 with mild-moderate… More >

Abstract Introduction: Indwelling stents produce symptoms and urinalysis findings mimicking urinary tract infection (UTI). In this study, we investigated the correlation of urinalysis findings with urine culture in patients with indwelling ureteral stents.
Materials and methods: All patients with ureteral stents who underwent stent removal in urology clinic from July 2013 to January 2015 and had urine culture available immediately prior to stent removal were included in this study. Urine culture results as well as age, gender, duration of indwelling stent, and reason for stent placement were collected.
Results: A total of 122 patients were included in this study.… More >

Abstract Introduction: Non-contrast CT (NCT) is commonly used to evaluate flank pain (FP). We sought to evaluate incidence of ureteral calculi on NCT in patients with FP, and to determine if clinical variables are associated with higher detection rates.
Materials and methods: Retrospective review identified 613 patients undergoing NCT for FP. Patient clinical data, NCT findings, and intervention were analyzed. Focus was placed on variables commonly associated with urolithiasis (V_stone), comprising hematuria, nausea/vomiting, and prior stone history. Statistical analysis was performed to identify risk of ureteral stones based on number and type of V_stone.
Results: No stone disease was identified… More >

Abstract Introduction: Robotic-assisted laparoscopic radical nephrectomy (RRN) is an increasingly utilized alternative to laparoscopic radical nephrectomy (LRN); however, there is little data on comparative effectiveness and cost of these procedures. We analyzed perioperative outcomes and hospital charge differences among patients undergoing laparoscopic radical nephrectomy (LRN) and robotic radical nephrectomy (RRN).
Materials and methods: Our institutional renal mass registry was queried for patients who underwent either LRN or RRN from 2010 to 2014. Demographic, perioperative outcomes and hospital charge data were compared between surgical approaches.
Results: Overall, 319 minimally invasive radical nephrectomies were performed during the study period. Of these,… 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 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 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 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: 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 >
