Non-intubated pyeloplasty for pelviureteric junction obstruction in children.

Sixty-one consecutive patients undergoing pyeloplasty (5 bilateral) were reviewed retrospectively; 54 pyeloplasties were non-intubated (NIP) and 12 were intubated. NIPs were managed by an extrarenal wound drain, which was removed after 2-4 days in 44 repairs with minimal or no urinary leakage and after 6-8 days in 10 with significant leakage. Fifty-two were successful after the primary procedure. One patient who developed a urinoma after drain removal required a percutaneous nephrostomy followed by a revision pyeloplasty. A second revision pyeloplasty was necessary for persistent postoperative obstruction. The results of NIP compared favorably with series where intubation was used routinely and were superior to alternative methods of management such as endopyelotomy.
