[Long-term surgical treatment outcome in ureteral neuromuscular dysplasia in children].

178 patients with ureteral neuromuscular dysplasia (UND) treated surgically were followed up for maximum 8 years. The following operations were made: resection of the stenosed part with antireflux operation by Politano-Leatbetter, Hendren operation, Lopatkin-Kalichinsky operation. Functional results depended on the condition of leiomyocyte regenerative reserves, deficiency of secretory renal function and the surgical method. In ureteral achalasia (by N. A. Lopatkin's classification) it is recommended to perform resection of the stenosed part by Politano-Leatbetter antireflux technique, in megaureter and ureterohydronephrosis Lopatkin-Kalichinsky operation is preferable.
