Internal inguinal hernia on the transplant side after kidney transplantation: a case report.

The patient was a 52-year-old man who presented with right inguinal swelling and pain. He had undergone kidney transplantation in 2005 and bypass surgery using a vascular prosthesis from the left axillary artery to the bilateral femoral arteries in 2008. The vascular prosthesis had invaded the right inguinal canal ventrally. The transplanted ureter had a hazy appearance on a non-enhanced abdominal CT scan. A Lichtenstein operation was performed under a diagnosis of inguinal hernia. A skin incision with pulling of tissue and subcutaneous fat was devised to avoid exposure of the vascular prosthesis. The inguinal canal and spermatic cord were found to have coalesced. The hernia was diagnosed as a supravesical hernia, class II-1. This case shows that a Lichtenstein operation is a suitable procedure for avoidance of damage to the transplanted ureter in treatment of a transplant-side inguinal hernia in a kidney transplant recipient.
