title: Early and late complications of ureteropyeloplasties at the junction.
abstract: In 282 patients with stenosis of the pyeloureteral junction who underwent surgical treatment the following postoperative complications occurred: urine leak, immediately after operation, in 16.6%, and acute renal infection resulting in nephrectomy, in 0.7%. During check-up examinations conducted in 181 patients within a period of one to seven years the following late and recurrent complications were observed: recurrent constrictions (stenoses) at the point of anastomosis, as well as renal calculi. Secondary stenoses with hydronephrosis occurred in 8.2%, renal calculi in 7.7%, whereas the coexistence of lithiasis with secondary subpelvic stenosis in 2.2% of patients. The best results were achieved in those operated on by the Anderson-Hynes method, without leaving a catheter in the ureter.
