DISMEMBERED PYELOPLASTY IN CHILDREN WITH AND WITHOUT STENTS

Objectives: To assess the benefit of performing nonstented pyeloplasty in infants. Methods: Forty-eight consecutive pyeloplasties were perfo rmed by two surgeons using different techniques, from 1987 to 1992. On e used stents in all cases (23) and the other performed a nonstented a nastomosis with external drainage (25 cases). Patients with specific i ndications for internal drainage, i.e. poor renal function, extreme py elocaliectasis, were excluded from the study. Parameters of cost and c omplications were assessed. Results: The group with stents had more fe brile episodes, needed more antibiotics and were hospitalized twice as long as the nonstented group. Pre- and postoperative renal function w as similar in both groups. Conclusions: Performing pyeloplasties in ch ildren without stenting the anastomosis is safe and cost-effective.
