Successful Multidisciplinary Repair of Severe Bilateral Uretero-Enteric Stricture with Inflammatory Reaction Extending to the Left Iliac Artery, after Robotic Radical Cystectomy and Intracorporeal Ileal Neobladder
Bibliographic record
Abstract
Uretero-enteric anastomotic strictures (UES) after robot-assisted radical cystectomy (RARC) represent the main cause of post-operative renal dysfunction. The gold standard for treatment of UES is open uretero-ileal reimplantation (UIR), which is often a challenging and complex procedure associated with significant morbidity. We report a challenging case of long severe bilateral UES (5 cm on the left side, 3 cm on the right side) after RARC in a 55 years old male patient who was previously treated in another institution and who came to our attention with kidney dysfunction and bilateral ureteral stents from the previous two years. Difficult multiple ureteral stent placement and substitutions had been previously performed in another hospital, with resulting urinary leakage. An open surgical procedure via an anterior transperitoneal approach was performed at our hospital, which took 10 h to complete, given the massive intestinal and periureteral adhesions, which required very meticulous dissection. A vascular surgeon was called to repair an accidental rupture that had occurred during the dissection of the external left iliac artery, involved in the extensive periureteral inflammatory process. Excision of a segment of the external iliac artery was accomplished, and an interposition graft using a reversed saphenous vein was performed. Bilateral ureteroneocystostomy followed, which required, on the left side, the interposition of a Casati-Boari flap harvested from the neobladder, and on the right side a neobladder-psoas-hitching procedure with intramucosal direct ureteral reimplantation. The patient recovered well and is currently in good health, as determined at his recent 24-month follow-up visit. No signs of relapse of the strictures or other complications were detected. Bilateral ureteral reimplantation after robotic radical cystectomy is a complex procedure that should be restricted to high-volume centers, where multidisciplinary teams are available, including urologists, endourologists, and general and vascular surgeons.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
