[Bilateral obstructive diseases of the upper urinary tract in children].
The authors examined 371 children aged 4 days to 15 years with obstructive diseases of the urinary tract. In 51 out of them there was bilateral hydronephrosis and 54 had bilateral obstructive megaureter. A new uretero-pelvic anastomosis was made in 47 children with bilateral hydronephrosis, in 31 out of them it was created successively. Resection of the pelvis was performed in 5 cases. Principles of the stepwise operative treatment are described as well as indications to a plasty without drainage in hydronephrosis. Operations were performed on 46 patients (92 ureters) with obstructive megaureter, 8 patients were treated conservatively. The conservative treatment is thought by the authors to be expedient in patients with compensated disturbance of urodynamics of the upper urinary tracts in obstructive megaureter and the every year rentgen-urodynamic control. Ureterocystoneostomy is indicated only in a progressing course of the disease.
