Primary obstructive megaureter (P.O.M.) is a dilatation, different in size, of upper urinary tract without reflux and secondary to a functional obstructive malformation of terminal segment of ureter. Infection and renal function impairment complicate P.O.M. in a rather high percentage of cases. In Authors' experience, in about 22% another urinary malformation and in more than 8% an extraurinary malformation are associated. Authors' experience in the treatment of 119 P.O.M. (102 patients) is reported. 14 P.O.M. (9 patients) were not operated on. In 104 megaureters (92 patients) an ureteric reimplantation with shortening and tailoring without preoperative temporary urinary diversion was carried out. In 4 megaureters a V.U.R. and in another 4 an ureteric stenosis taken place as postoperative complications. In 96 ureters (92.3%) positive results were obtained with normalisation or impressive improvement of upper urinary tract and improvement of renal function.
