Hydronephrosis

Abstract

Hydronephrosis is probably caused by a muscular anomaly at the pelvi-ureteric junction. A pyeloplasty technique involving the resection of this anomalous portion has been generally recommended. However, this study shows that procedures which preserve the anatomical continuity might also lead to excellent late results. The immediate postoperative complications were few and minor, and the low incidence of complications was partly the result of the splinting technique, which is therefore recommended. A scheme for evaluation of late results is suggested.
