BACKGROUND AND PURPOSE: Little is known about the incidence and treatment of ureteropelvic junction (UPJ) obstruction of renal grafts. We report on three cases treated by endopyelotomy. PATIENTS AND METHODS: Graft function declined in three patients 98, 135, and 144 days after kidney transplantation. Acute rejection was excluded by renal biopsy. Ultrasonography revealed a dilated collecting system, and a percutaneous nephrostomy tube was placed. An antegrade nephrostogram showed UPJ obstruction. Percutaneous antegrade endopyelotomy was performed with the cold-knife technique, and the area was stented for 6 weeks using a 14F/8.2F Smith endopyelotomy stent. RESULTS: No intraoperative or postoperative complications occurred. The endopyelotomies were successful, and the creatinine clearances returned to normal. CONCLUSION: Antegrade endopyelotomy in patients with UPJ obstruction of a renal graft is feasible and effective. Normal kidney function was restored after correction of the obstruction.
