[Surgical correction of primary nonrefluxing megaureter in children and its remote results].

Correction of primary non-reflux megaureter (153 ureters) was made in 136 patients aged 3 months to 14 years. Bilateral disease was in 17 patients. Non-reflux non-obstructive megaureter was in 113 cases, obstructive in 40 cases including association with ureterocele in 23 cases. Resection of distal ureter with its neoimplantation into the urinary bladder according to the antireflux technique was made in 146 patients, endovesical electroperforation and resection of ureterocele were made in 5 and 2 patients, respectively. Good results were obtained in 88.3% (135 ureters), satisfactory in 2.6% (4 ureters), unsatisfactory in 9.1% (14 ureters). After effective correction of megaureter, the treatment should be focused on adequate therapy of pyelonephritis present in 90% examinees, on improvement of urodynamics and stabilization of sclerotic process in renal parenchyma. The patients need long-term follow-up and more effective treatment.
