Background: The Optilume paclitaxel drug-coated balloon (DCB) is a relatively new-to-market alternative in the management of male anterior urethral stricture disease. The pivotal trial excluded patients with a history of urethroplasty, although these strictures may be amenable to endoscopic management. Therefore, we sought to assess the efficacy of the DCB in the management of recurrent strictures following urethroplasty.

Background: Three common strategies exist for managing the inflatable penile prosthesis reservoir during revision surgery: the original reservoir can be (a) removed, (b) deactivated and left in situ, sometimes referred to as "drain and retain" (DR), or (c) validated and reconnected to new cylinders, which we have termed "reservoir recycling" (RR).

Aim: To compare the efficacy and safety of the RR approach to penile prosthesis revision against DR and the recommended approach of complete device removal and replacement.

Methods: A retrospective chart review of our single-surgeon inflatable penile prosthesis database between 2007 and 2022 was performed, identifying revision surgeries.

Article Synopsis
  • The study aimed to evaluate the safety and effectiveness of administering high doses of phenylephrine (over 1000 μg) hourly for treating acute ischemic priapism (AIP), while monitoring potential adverse hemodynamic events.
  • A retrospective review of 123 AIP patients showed that 63.9% achieved resolution of their condition with phenylephrine, with no significant difference in resolution rates between low and high dose groups, although some patients experienced hemodynamic changes.
  • The findings suggest that phenylephrine's effectiveness in resolving AIP is not dependent on dosage, and there may be underreported hemodynamic complications; further research is recommended to improve risk assessment and

Purpose: We sought to determine the role of body mass index (BMI) on quality indicators, such as length of stay and readmission. The National Surgical Quality Improvement Program (NSQIP) database was queried to examine the effect of obesity, defined as BMI >30, on outcomes after Minimally Invasive Radical Retropubic Prostatectomy (MI-RRP).

Materials And Methods: Utilizing the NSQIP database, patient records were identified using the Current Procedural Terminology (CPT) code 55866 (laparoscopy, surgical prostatectomy, radical retropubic) during a 10-year period (2007-2017).

Objectives: We hypothesize that men with diabetes mellitus whose inflatable penile prosthesis (IPP) implantation is delayed for unacceptably high hemoglobin A1c (HbA1c) will have durable improvements in their glycemic control after achieving acceptable HbA1c levels for surgery.

Methods: Per institutional protocol, an A1c <9% must be documented prior to IPP placement. After IRB approval, a single surgeon IPP database was retrospectively queried for data specific to diabetes mellitus management.
