Inguinal Herniation of the Transplanted Ureter: A Systematic Review

Résumé fourni par la source

Herniation of the transplanted ureter into the inguinal canal is an exceptionally rare complication following renal transplantation. Most cases present as delayed-onset obstructions, typically occurring more than one year post-transplant and often involving the ipsilateral inguinal canal. We presented the case of a 49-year-old male kidney transplant recipient who developed obstructive uropathy due to herniation of the graft ureter into the ipsilateral inguinal canal. Diagnosis was confirmed by computed tomography (CT), which proved superior to ultrasonography in delineating the ureteral course. A JJ ureteral stent was successfully placed, followed by inguinal hernia repair using the Lichtenstein technique. The postoperative course was uneventful, with complete resolution of symptoms and preservation of graft function. Transplanted ureteral herniation is a rare but important cause of late post-transplant obstruction. Cross-sectional imaging, particularly CT, offers greater diagnostic accuracy than ultrasound alone in identifying ureteral displacement. When feasible, primary ureteral stenting may obviate the need for nephrostomy, thereby reducing patient morbidity.
