Clinical Practice Patterns for Surgical Shunts and Penile Prosthesis Placement in Men With Priapism: A Retrospective Large Claims Database Analysis

Abstract

Introduction: The objective of this study was to assess the rates of surgical shunting and prosthesis placement for acute ischemic priapism using a large multi-institutional claims database.

Methods: A US claims database network (TriNetX Diamond Network) was queried from 2010 to 2020. We constructed a cohort of men ages ≥ 16 years who (1) had a diagnosis of priapism and (2) underwent an irrigation of the corpora cavernosa for priapism. We assessed the number of men who then had a surgical penile shunt or penile prosthesis placement. Demographics, time to surgical procedure, and order of procedures were collected.

Results: A total of 6392 men were identified with the diagnosis of priapism and the procedure of corpora cavernosal irrigation. Of these men, 693 (11%) proceeded to surgical shunt. One hundred forty-four men (2%) underwent initial penile prosthesis placement. Of the men undergoing initial penile prosthesis, only 17 of 144 (12%) cases occurred within the first month of corpora cavernosal irrigation. Finally, when assessing choice of initial shunts vs initial penile prosthesis before and after 2015, overall rates of initial shunt (10.0% vs 8.5%, P < .0001) and initial prosthesis (3.1% vs 2.1%, P < .0001) were lower after 2015 when compared with rates prior to 2015.

Conclusions: In this US claims-based analysis of men presenting with ischemic priapism and treated with initial irrigation, a small percentage (11%) of men went on to receive surgical shunting, and only 2% received an initial prosthesis. Men receiving initial prostheses were more likely to have more comorbidities, and overall surgical management of priapism has decreased over time.
