Characterizing and Quantifying Material Fatigue of the Artificial Urinary Sphincter Pressure Regulating Balloon.

Objective: To characterize and quantify changes in elastic properties and in vivo pressure characteristics of pressure regulating balloons (PRB) over time, we conducted an analysis of the mechanical characteristics of the PRB after removal from patients for revision surgery.

Methods: Pressure and elasticity characteristics of new and used 61-70 cm HO PRBs were analyzed. Pressure-volume curves were generated using commercially available urodynamics equipment.

Urethral Stricture Formation After Artificial Urinary Sphincter Cuff Erosion Is Uncommon in the Absence of Pelvic Radiation.

Purpose: Reported rates of urethral stricture development after artificial urinary sphincter erosion are highly variable. We hypothesized that the risk of stricture is commensurate with the degree of erosion.

Materials And Methods: We reviewed our prospectively maintained quality improvement database for all patients with artificial urinary sphincter erosion from 2011 to 2022.

Multi-institutional review of non-hypospadiac penile urethral stricture management and outcomes.

Objectives: Penile urethral stricture disease not associated with hypospadias is rare, and there is a wide range of commonly used surgical repair techniques for this disease. We sought to compile a multi-institutional database of patients who had surgical correction of strictures in the penile urethra not limited to the meatus, and who had no history of hypospadias, for analysis using the Trauma and Urologic Reconstructive Network of Surgeons length, urethral segment and etiology classification system.

Methods: A retrospective database from 13 institutions was compiled of patients who had undergone surgical correction of Trauma and Urologic Reconstructive Network of Surgeons length, urethral segment and etiology urethral stricture segments S2b/S2c and excluding E5, with a minimum follow-up time of 4 months.

A multimodality review of male urethral imaging: pearls and pitfalls with an update on urethral stricture treatment.

Optimum radiological assessment of the male urethra requires knowledge of the normal urethral anatomy and ideal imaging techniques based on the specific clinical scenario. Retrograde urethrography is the workhorse examination for male urethral imaging, usually utilized as the initial, and often solitary, modality of choice not only in the setting of trauma, but also in the pre- and post-operative evaluation of urethral strictures. There is, however, growing interest in utilization of ultrasound and magnetic resonance for evaluation of the male urethra owing to lack of ionizing radiation and improved delineation of the adjacent tissue.

Evaluation of Missed Clinic Visits at an Academic Multi-Provider Urology Clinic.

Introduction: In this study we elucidated patient characteristics and reasons for visit associated with missed appointments for patients in a multi-provider urology clinic.

Methods: We retrospectively reviewed characteristics of clinic patient data for 4 urologists at 0.5 FTE (full-time equivalent) at a single location between March 18, 2014 and March 18, 2015.
