Obstructive uropathy after inguinal herniorrhaphy with a mesh in a renal transplant patient.

A 67-year-old male renal transplant patient presented with a right inguinal bulging mass, and was diagnosed with a right indirect inguinal hernia. The day following inguinal herniorrhaphy, serum creatinine became elevated. The patient was oliguric and had abdominal pain on the first day after inguinal herniorrhaphy with a mesh. We diagnosed him with acute renal failure and subsequently performed acute hemodialysis. The kidney computed tomography showed hydronephroureter, with distal ureter obstruction. With urgent percutaneous nephrostomy, we were able to relieve the obstructive uropathy with distal ureteral stenosis. Subsequently, hernia repair was performed with removal of the mesh, followed by the antegrade ureteral stent insertion. Renal function was recovered after ureteral stent insertion. This case shows that acute renal failure can occur due to ureteral obstruction, complicated by an inguinal hernia repair, and this can be successfully treated with percutaneous nephrostomy and inguinal hernia repair with mesh removal.
