Kidney Transplantation in a Child with Posterior Urethral Valve from a Hepatitis B Virus-Carrier Mother

Abstract

The case of a 7-year-old boy with posterior urethral valve (PUV) who underwent successful kidney transplantation for progressive renal failure is reported. He required complex reconstructive surgery for PUV-related disorders, and also specific serological preparation for hepatitis B (HB) as his living donor mother was a proven carrier. By carefully executing the principles of reconstructive surgery and with well-planned seroimmunological preparation, we have demonstrated that successful kidney transplantation can be done from an HB Ag-positive mother to an HB Ag- and HB Ab-negative son, even when his urinary tract is severely dysfunctional due to PUV.
