Thermographic imaging is a technique to measure infrared radiation to report temperature and has been used in prior research to assess sexual arousal by measuring genital temperature. We hypothesized this can be used quantitatively to assess erectile function. We conducted an observational clinical trial of this technique by performing thermographic imaging in the flaccid and erect state and compared these values with hemodynamic measurements performed by penile Doppler/duplex ultrasound (PDDU).

Purpose: Holmium laser enucleation of the prostate (HoLEP) is a surgical treatment option for benign prostatic hyperplasia (BPH). Many men develop retrograde ejaculation postprocedure, but there is conflicting evidence regarding sexual function outcomes post-HoLEP. We sought to examine significant variations in patient-reported erectile and ejaculatory function within 12 months post-HoLEP.

Purpose Of Review: Benign prostatic hyperplasia affects the quality of life of a significant number of men, especially as they age. There are continuous innovations in the surgical management of benign prostatic hyperplasia, but many of these innovations are studied in the core population of men 50-70 years of age. This review focuses on the outliers of men aged 18-50 and 70 and older.

Holmium laser enucleation of the prostate (HoLEP) has become a new surgical gold standard treatment for benign prostatic hyperplasia (BPH). It is known that untreated BPH can lead to bladder outlet obstruction (BOO). A positive correlation exists between BOO and chronic kidney disease (CKD), but stability or recovery of renal function after HoLEP remains unknown.

Objective: To compare the quality of robotic prostatectomy surgical videos on the popular website YouTube with more curated, professional sources using the Global Evaluative Assessment of Robotic Skills (GEARS) criteria.

Methods: A search was performed on YouTube for robotic prostatectomy. Results were sorted by views and the first ten that met inclusion criteria were selected for review.

Introduction: Multiple studies have linked preoperative nutrition status to postoperative outcomes. This relationship has been little studied in urology. We used a standardized, national, risk-adjusted surgical database to evaluate 30-day outcomes of patients undergoing common urologic oncologic procedures as they related to preoperative albumin.

Purpose: We describe the efficacy of radical prostatectomy to achieve complete primary tumor excision while preserving erectile function in a cohort of patients with high risk features in whom surgical resection was tailored according to clinical staging, biopsy data, preoperative imaging and intraoperative findings.

Materials And Methods: In a retrospective review we identified 584 patients with high risk features (prostate specific antigen 20 ng/ml or greater, clinical stage T3 or greater, preoperative Gleason grade 8-10) who underwent radical prostatectomy between 2006 and 2012. The probability of neurovascular bundle preservation was estimated based on preoperative characteristics.

Introduction: Complication rates of open radical prostatectomies (ORPs) and laparoscopic radical prostatectomies (LRPs) performed by highly experienced surgeons in centers of excellence are well known. Using a standardized, national, risk-adjusted surgical database, we compared 30-day outcomes following ORP and LRP and analyzed how trainee involvement influenced outcomes.

Methods: The American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) is a risk-adjusted data collection analyzing preoperative risk factors, demographics, and 30-day postoperative outcomes.
