    Abstract:
    Twenty-five of 34 patients who underwent pyeloplasty operation for ureteropelvic junction obstruction were able to be followed up for three months or more after operation. Postoperative results were compared in twenty-six kidneys of these patients according to clinical conditions such as age, duration of indwelling nephrostomy tube and splint catheter, operative method (one-stage or two-stage operation), preoperative urinary tract infections, preoperative grade of hydronephrosis and the postoperative period evaluated. Postoperative results evaluated at three months after operation, revealed no case with excellent improvement. At 36 months after operation excellent improvement rate was 46.7% and there was a significant difference in excellent improvement rate between these times. At 3, 6, 12 and 36 months after operation, improvement rate was 35.7, 55.0, 52.9 and 86.7%, respectively. At 3 and 6 months or more, deterioration rate was 29 and 0%, respectively. It is concluded that evaluation of pyeloplasty should be done at least 6 months after operation and even if renal function is stable at this period, more improvement in renal function can be expected at one year or more after operation.
