We report the first documented case of an inguinal hernia containing bladder, resulting incontralateralallograft hydroureteronephrosis. A 39-year-old male patient presented with allograft dysfunction, a contralateral inguinoscrotal hernia, and marked hydroureteronephrosis on ultrasound (US). Percutaneous nephrostogram and a retrograde cystogram suggested bladder herniation with incorporation of the contralateral ureteroneocystostomy into the hernia. Paraperitoneal bladder herniation was confirmed at surgery and hernioplasty was performed. Six-week follow-up revealed normal renal function with no sign of hernia recurrence. Despite occurring rarely, transplant ureter or bladder herniation should be considered in the differential diagnosis of hydroureteronephrosis. This case illustrates that the contralateral position of hernia to allograft does not necessarily preclude the hernia as the source of ureteric obstruction.

The authors present the first case report of inguinal herniation causing contralateral allograft hydroureteronephrosis.
