Clinical History: The case is a 17-year-old boy with a history of bilateral grade 4 vesicoureteral reflux and end-stage renal disease who underwent a living-unrelated donor renal transplantation in November 2021. He presented in June 2022 with vague abdominal pain and creatinine 4.3 mg/dL. Physical Examination: Transplant biopsy showed no evidence of acute rejection. Antegrade nephrostogram at the time of nephrostomy tube placement demonstrated hydronephrosis and a focal stricture of the proximal transplant ureter. His anatomy was further complicated because of prior ligation of his native distal right ureter at the time of transplant and intraperitoneal location of his transplant kidney through a peritoneal window. Diagnosis: Focal proximal stricture of transplant ureter. Intervention: Given the complex anatomy, a 3D-printed anatomical model was created to facilitate surgical planning. The 3D model highlighted a complex trajectory of the proximal ureter and strictured segment directly posterior to the transplant hilar vessels. In addition, the transplant kidney was directly overlying the dome of the bladder because of its intraperitoneal location. Given these anatomic considerations, the patient underwent an uncomplicated robot-assisted ureteropelvicostomy between his native left ureter and transplant renal pelvis. Follow-Up/Outcomes: Total robotic operative time was 2 hours 17 minutes. He was dismissed on postoperative day 1 with a creatinine nadir equivalent to his post-transplant baseline at 10-week follow-up. 3D-printed models have utility in select cases with complex anatomy. These models facilitate accurate regional and spatial anatomy of critical structures to enable effective operative planning. No competing financial interests exist.

Objectives: To characterize 30-day morbidity of upper ureteral reconstruction (UUR) and lower ureteral reconstruction (LUR) surgery by comparing open and minimally invasive surgery (MIS) approaches using a national surgical outcomes registry. Methods: The American College of Surgeons National Surgical Quality Improvement Program database was reviewed for patients who underwent UUR and LUR between 2007 and 2017. Primary endpoints included 30-day complications, transfusion, readmission, return to operating room (ROR), and prolonged postoperative length of stay (LOS). Multivariable logistic regression was performed to observe the association of MIS approach on 30-day outcomes. Results: Three thousand forty-two patients were identified with 2116 undergoing UUR and 926 undergoing LUR. Of 2116 patients undergoing UUR, 1733 (82%) were performed through an MIS approach. On multivariable analysis, open approach for UUR was associated with increased odds of any 30-day complication (odds ratio (OR) 1.6 [1.1–2.4]; p = 0.014), major complication (OR 1.8 [1.04–3.0]; p = 0.034), transfusion (OR 3.7 [1.2–11.5]; p = 0.025), ROR (OR 2.0 [1.0–3.9]; p = 0.047), and prolonged LOS (OR 5.4 [3.9–7.6]; p < 0.001). Of the 926 patients undergoing LUR, 458 (49%) were performed through an MIS approach. On multivariable analysis, open approach for LUR was associated with increased odds of any 30-day complication (OR 1.5 [1.1–2.1]; p = 0.028), minor complication (OR 1.7 [1.1–2.6]; p = 0.02), transfusion (OR 8.1 [2.7–23.7]; p < 0.001), and prolonged LOS (OR 4.2 [2.4–7.3]; p < 0.001). Conclusion: Utilization of a national surgical database revealed an open approach was associated with increased 30-day morbidity across multiple postoperative outcome measures. These findings suggest an MIS approach should be considered, when feasible, for upper and lower ureteral reconstruction.

Objective To describe the natural history, reconstructive solutions, and functional outcomes of those men undergoing pubectomy and urinary reconstruction after prostate cancer treatment. Patients and Methods This study retrospectively identified 25 patients with a diagnosis of urosymphyseal fistula (UF) following prostate cancer therapy who were treated with urinary reconstruction with pubectomy. This study describes the natural history, reconstructive solutions, and functional outcomes of this cohort. Results All 25 patients had a history of pelvic radiotherapy for prostate cancer. The median (interquartile range [IQR]) time from prostate cancer treatment to diagnosis of UF was 11 (6, 16.5) years. The vast majority of men (24/25; 96%) presented with debilitating groin pain during ambulation. Posterior urethral stenosis was common (20/25; 80%), with 60% having repetitive endoscopic treatments. Culture of pubic bone specimens demonstrated active infection in 80%. Discordance between preoperative urine and intraoperative bone cultures was common, 21/22 (95.5%). After surgery, major 90‐day complications (Clavien–Dindo Grade III and IV) occurred in eight (32%) patients. Pain was significantly improved, with resolution of pain (24/25; 96%) and restoration of function, the median (IQR) preoperative Eastern Cooperative Oncology Group Performance Status (ECOG PS) was 3 (2, 3) vs median postoperative ECOG PS score of 0 (0, 1). Conclusion Endoscopic urethral manipulation after radiation for prostate cancer is a risk factor for UF. Conservative management will not provide symptom resolution. Fistula decompression, bone resection, and urinary reconstruction effectively treats chronic infection, improves pain and ECOG PS scores.

Abstract Aim Up to 10% of patients who undergo nonurological abdominopelvic operations suffer a ureteral injury. While preoperative ureteral stenting to facilitate identification of the ureter is common, it does not reduce the incidence of intraoperative ureteral injury and is not without risk. As we continue to broaden the application of minimally invasive surgical techniques, a new form of ureteral identification and avoidance that does not rely on tactile feedback is needed. We report our initial experience with intraureteral indocyanine green (ICG) for ureteral identification and avoidance during complex robotic‐assisted colorectal surgery. Method Patients undergoing adjunctive ureteral identification during robotic‐assisted colorectal surgery were prospectively identified. Each patient underwent intraureteral ICG administration using rigid cystoscopy (22 Fr). A 5‐Fr open‐ended ureteral catheter was inserted up to 20 cm and used to inject 5 ml of 2.5 mg/ml ICG as the catheter was withdrawn to the ureteral orifice. Intraureteral ICG was then detected using near‐infrared laser fluorescence technology (Firefly®). Results Successful ICG‐enhanced ureteral identification and avoidance was performed in 15 of 16 (94%) patients undergoing robotic‐assisted colorectal surgery. The median ICG instillation time was 11.5 min (range 4–21 min) and the median operative time with ICG visualization was 489 min (8 h 9 min) [range 268–738 min (4 h 28 min–12 h 18 min)]. No patient experienced intraoperative ureteral injury and there were no adverse sequelae or complications associated with intraureteral ICG administration. Conclusion Intraureteral ICG is a safe and effective method of intraoperative ureteral identification and avoidance during complex robotic‐assisted colorectal surgery. Precise and prolonged ureteral visualization was achieved, allowing for long operative times compatible with complex robotic‐assisted operations.
