[Ligation of the native ureter in kidney transplant].

The urinary tract reconstruction in renal transplantation is usually performed by a ureterocystoneostomy according to Gregoire-Lich technique. In selected patients, native ureteral ligation with nephrectomy was done when end-to-end anastomosis for ureteroureterostomy was performed. Recently, some Authors have proposed the ligation of the native ureter without nephrectomy. We report our experience in the ligation of the native ureter with no associated nephrectomy. MATERIALS AND METHODS. In 978 renal transplantations performed from April 1986 through December 2006, we evaluated 68 recipients (69.5%) who underwent ureteral ligation without nephrectomy. Mean diuresis was 314 cc/day (range 0-1200 cc/day). Follow-up was 1 to 187 months. RESULTS. Only one patient (1.5%) required native nephrectomy for fever and abdominal pain. None of the other patients showed infections involving native kidney or flank pain during the follow-up. DISCUSSION AND CONCLUSION. Our experience confirms the safety and feasibility of native ureter ligation without omolateral nephrectomy. Nephrectomy is indicated in the case of coexistent intrinsic renal disease, such as non-treatable nephrovascular hypertension, symptomatic polycystic kidney disease, chronic renal infection.
