Management of pyeloureterotomy incision.

We reviewed 122 cases of pyeloureterolithotomy. The pyeloureterotomy incision was closed loosely in 70 cases and not closed in 52 cases. The duration of urinary leakage had no difference statistically between no closure and loose closure (p greater than 0.01). The duration of urinary leakage from the renal pelvis and the upper ureter was shorter than that from the lower ureter in both loose and no closure (p less than 0.05). There was no postoperative stricture. In difficult closures it is not necessary to close the pyeloureterotomy incision.
