title: [Long-term results of the surgical treatment of primary obstructive megaureter in children].
abstract: In 1989-1998 reconstructive plastic operations for primary obstructive megaureter (POM) were made in 71 children. Ureterocystoneostomy with antireflux defense was made in 35 children. Prior trocar nephrostomy was performed in 5 patients with bilateral megaureter and decompensation of the upper urinary tracts. Extensive resections of the dilated ureters with their longitudinal modelling were not used. Long-term results were good: 85.7% of the children recovered, 8.6% improved. Morphometric examinations of the distal obturating ureters before surgery and 6 months to 9 years after it showed that after operative reestablishment of ureteral patency diameter of the ureter reduced 6.2- and 5.5-fold, on the average, in children under 5 years and 6-14-year-olds, respectively. It was also demonstrated that recovery of ureteral contractility and diminution of its size need time (at least 1-1.5 years). The author does not recommend to make longitudinal modelling of the ureter in children, especially in infants.
