Case in brief
A 67-year-old man developed bilateral hydronephrosis from ureteroileal anastomotic strictures after robot-assisted radical cystectomy and ileal conduit diversion. Three years after the original surgery, he underwent robotic conversion of the intracorporeal conduit to a Studer orthotopic ileal neobladder, including resection of stenotic ureteral segments and reconstruction of the urethral outlet. The operation was completed without open conversion; estimated blood loss was 100 mL, and he was discharged on postoperative day 15. At four months, renal function had improved, and he reported satisfactory daytime and nighttime continence with smooth voiding.
What made this case unusual
The case demonstrates intracorporeal conversion of an established ileal conduit to an orthotopic neobladder using the Kangduo 2000 Robotic System despite bilateral ureteroileal strictures and postoperative adhesions.
Diagnostic / clinical pearl
In a patient with an ileal conduit and bilateral hydronephrosis, ureteroileal anastomotic strictures may be the underlying cause; this report also illustrates that robotic conversion to an orthotopic neobladder was technically completed in this setting.
Why it matters
The favorable early outcome is preliminary; longer follow-up and larger cohorts are needed to validate the feasibility, safety, and effectiveness of this approach.
