Introduction
Ileal conduit diversion is commonly performed after cystectomy and is considered the gold standard. However, late complications can occur.
Case Presentation
A 74‐year‐old woman had undergone cystectomy with ileal conduit diversion for neurogenic bladder dysfunction 47 years earlier. She presented with recurrent urinary tract infections and bilateral hydroureteronephrosis. Imaging revealed conduit stenosis and impaired bilateral renal function. Endoscopy of ileal conduit revealed a pinhole‐like stenosis on the proximal side. A 10‐Fr catheter was advanced across the stenotic segment, resulting in pyelonephritis resolution and renal function improvement. After 1 month, the catheter was upsized to 16‐Fr. Five months later, the catheter was spontaneously expelled, and good urine flow was maintained, with no recurrence over 2 years of follow‐up.
Conclusion
Ileal conduit stenosis can occur even decades after urinary diversion and can be managed effectively by stepwise dilation. The present case highlights the need for lifelong surveillance in ileal conduit patients.
