Postoperative stress urinary incontinence (SUI) after Holmium Laser Enucleation of the Prostate (HoLEP) has improved with the early apical release (EAR) technique. However, some patients develop SUI despite using EAR HoLEP. The aim of this study is to investigate whether a novel classification of the external sphincter is correlated with postoperative SUI.

Background: Low-intensity shockwave therapy for erectile dysfunction is emerging as a promising treatment option.

Aim: This randomized sham-controlled crossover trial assessed the efficacy of low-intensity shockwave therapy in the treatment of erectile dysfunction.

Methods: Thirty-three participants with organic erectile dysfunction were enrolled and randomized to shockwave therapy (n = 17) or sham (n = 16).

Objective: To compare the oncological and renal function outcomes of microwave ablation (MWA) compared to partial nephrectomy (PN) in two small renal mass (SRM) tumor size cohorts, <3 cm and 3-4 cm.

Materials And Methods: This study included retrospective data from 2009 to 2015 and prospective data since 2015 from a single-institution database. Patient demographics, renal mass characteristics, and treatment outcomes were collected.

Purpose: To compare the oncological and renal function outcomes for patients receiving microwave ablation (MWA) in tumors < 3 and 3-4 cm.

Methods: Retrospective analysis of a prospectively maintained database identified patients with < 3 or 3-4 cm renal cancers undergoing MWA. Radiographic follow-up occurred at approximately 6 months post-procedure and annually thereafter.

Objective: To characterize academic productivity for underrepresented minorities (URMs) vs non-URMs and by gender in Urology.

Methods: A database was created from 145 Urology residency programs. URM status was determined by origin of name, photo, biography, Twitter, LinkedIn, and Doximity.

Purpose: The majority of newly diagnosed renal tumors are masses < 4 cm in size with treatment options, including active surveillance, partial nephrectomy, and ablative therapies. The cost-effectiveness literature on the management of small renal masses (SRMs) does not account for recent advances in technology and improvements in technical expertise. We aim to perform a cost-effectiveness analysis for percutaneous microwave ablation (MWA) and robotic-assisted partial nephrectomy (RA-PN) for the treatment of SRMs.

Introduction: We sought to determine and compare the perioperative cost associated with percutaneous microwave ablation (MWA) and robot-assisted partial nephrectomy (RA-PN) for treatment of localized renal masses (LRMs).

Methods: We conducted a retrospective cohort analysis of a prospectively maintained IRB-approved LRM database. The database was queried for patients treated with microwave ablation or partial nephrectomy from 2015 to 2020.

Objectives: To define the prevalence of cognitive impairment and sphincter misuse among men who had undergone AUS placement.

Methods: Men who had previously undergone AUS placement from 2004 to 2019 were assessed through comprehensive telephone surveys. The primary survey outcome was cognitive function, assessed via validated Telephone Mini-Mental State Examination.
