Objective: To develop a patient-reported outcome measure (PROM) using qualitative patient-centered methods and expert opinion to quantify the impact of ureteral stricture disease (USD) and its management.

Methods: Patients undergoing robotic ureteral reconstruction for USD between 9/2021-4/2023 were enrolled. A novel patient-reported outcome was developed in four steps: (1) Semistructured concept elicitation interviews to evaluate the physical, mental, and social effects of USD; (2) Item generation based on themes identified in the interview transcripts, existing patient-reported outcomes on health-related Quality of Life, and expert opinion; (3) Feedback on the generated items from a panel of external clinicians with high surgical volume for USD; and (4) Cognitive interviews assessing patient comprehension and relevance.

Article Synopsis
  • The study aimed to identify preoperative factors that predict surgical success in patients undergoing robotic ureteral reconstruction (RUR) for distal ureteral strictures by reviewing data from 284 patients.
  • Various surgical procedures were performed, and the team analyzed variables affecting surgical outcomes, particularly focusing on obesity and ureteral rest as significant predictors.
  • Results indicated that patients with obesity had lower odds of surgical success, while those who had ureteral rest prior to surgery significantly improved their chances of a successful outcome.

Article Synopsis
  • The study aims to assess if computed tomography (CT)-based renal parenchymal volumes can be used to predict split renal function (SRF) in patients with ureteral stricture disease (USD) to inform surgical decisions.
  • A retrospective review of patients indicated strong reliability in calculating renal volumes between raters and found a significant correlation between CT-derived SRF estimates and those from nuclear medicine scans.
  • The findings suggest that CT analysis of kidney volume could potentially replace the need for preoperative nuclear scans in some patients, simplifying the evaluation for surgical management.

Objective: To investigate predictors of surgical success for patients undergoing robotic ureteral reconstruction (RUR) for ureteropelvic junction obstruction (UPJO), proximal, and middle ureteral stricture disease.

Methods: We retrospectively reviewed our multi-institutional Collaborative of Reconstructive Robotic Ureteral Surgery database to identify all consecutive patients undergoing RUR for UPJO, proximal and/or middle ureteral stricture disease between April 2012 and December 2020. The specific reconstruction technique was determined by the primary surgeon based on clinical history and intraoperative findings.

Introduction: Fournier's gangrene (FG), is a progressive, necrotizing soft tissue infection of the external genitalia, perineum, and/or anorectal region. How treatment and recovery from FG impacts quality of life related to sexual and general health is poorly characterized. Our purpose is to evaluate the long term impact of FG on overall and sexual quality of life using standardized questionnaires through a multi-institutional observational study.

Objectives: To describe our multi-institutional experience with robotic ureteral reconstruction (RUR) in patients who failed prior endoscopic and/or surgical management.

Materials And Methods: We retrospectively reviewed our Collaborative of Reconstructive Robotic Ureteral Surgery (CORRUS) database for all consecutive patients who underwent RUR between 05/2012 and 01/2020 for a recurrent ureteral stricture after having undergone prior failed endoscopic and/or surgical repair. Post-operatively, patients were assessed for surgical success, defined as the absence of flank pain and obstruction on imaging.

We compared outcomes of robot-assisted simple prostatectomy (RASP) in patients with and without a history of prior prostate surgery for management of symptomatic benign prostatic hyperplasia (BPH). We retrospectively reviewed our multi-institutional database for all consecutive patients who underwent RASP between May 2013 and January 2021. Postoperatively, urinary function was assessed using the American Urological Association symptom score (AUASS) and quality of life (QOL) score.

Surgical treatments for Peyronie's disease and erectile dysfunction are generally straightforward and associated with excellent outcomes. However, severe (>60°) and multidirectional curvature, hourglass deformity, severe penile shortening, and ossified plaque may complicate surgery in patients with Peyronie's disease. Similarly, a history of priapism, prior implant infection, and penile injury can pose challenges to successful implant surgery secondary to severe corporal fibrosis.

Objectives: To describe a systematic method to quantify the severity of renal infarction injury and assess its association with post-traumatic renal function after blunt trauma.

Methods: We retrospectively reviewed all patients who suffered an AAST grade IV renal infarction injury without active bleeding secondary to blunt trauma between 1/2010 and 10/2020. Only patients with a pre-traumatic eGFR within 12 months of injury and post-traumatic eGFR within 3-12 months were included.

Objective: To report our contemporary experience with ureteral injuries secondary to blunt trauma, with diagnostic methods and management stratified according to injury severity.

Materials And Methods: We performed a retrospective 15-year study (4/2005-4/2020) at a regional level I trauma center. Patients were categorized as having a partial or complete transection injury.

To demonstrate feasibility of robot-assisted laparoscopic (RAL) ureteroureterostomy (UU) for benign distal ureteral strictures (DUS) in our robotic reconstruction series with long-term follow-up. In a retrospective review of our prospectively maintained RAL ureteral reconstruction database, we followed patients between June 2012 and February 2019 who underwent a UU for DUS. In addition to patient demographics, we recorded the etiology, stricture length, and recurrence rates.

Since the advent of the robotic surgery, its implementation in urology has been both wide and rapid. Particularly in extirpative surgery for prostate cancer, techniques in robotic-assisted radical prostatectomy have-and continue to-evolve to maximize functional and oncologic outcomes. In this review, we briefly present a historical perspective of the evolution of various robotic techniques, allowing us to contextualize contemporary robotic approaches to radical prostatectomy.

Introduction: To assess whether patients with a large renal mass, treated by radical nephrectomy (RN), could have benefited from preoperative renal mass biopsy (RMB). The decision to perform partial nephrectomy (PN) for an organ-confined > 4 cm renal mass can be complex. Albeit often feasible, oncologic safety of PN in this cohort is debated.

We describe a case of a patient who suffered a grade IV renal injury who demonstrated vicarious excretion of intravenous contrast into the bowel masquerading as a nephroenteric fistula. Despite concerning imaging features, given the patient's lack of clinical symptoms of a nephroenteric fistula, negative oral activated charcoal test, and our understanding of the pharmacokinetics of intravenous contrast, our suspicion for nephroenteric fistula was low. This case highlights the importance of carefully considering the mechanism of injury when developing a differential diagnosis of potential sequela after trauma and understanding the pharmacokinetics of intravenous contrast in the trauma setting.

Surgical management of long-segment radiation-induced distal ureteral strictures (RIDUS) is challenging. Pelvic radiation can damage the bladder, inhibiting the utilization of typical reconstruction techniques such as a psoas hitch and/or Boari flap. Also, radiation can cause scarring that can make ureterolysis difficult.

Purpose: To report our intermediate-term, multi-institutional experience after robotic ureteral reconstruction for the management of long-segment proximal ureteral strictures.

Materials And Methods: We retrospectively reviewed our Collaborative of Reconstructive Robotic Ureteral Surgery (CORRUS) database to identify all patients who underwent robotic ureteral reconstruction for long-segment (≥4 centimeters) proximal ureteral strictures between August 2012 and June 2019. The primary surgeon determined the specific technique to reconstruct the ureter at time of surgery based on the patient's clinical history and intraoperative findings.
