[Interpelvic, ureteropelvic and interureteral anastomoses in duplication of the kidney and the ureter].

The surgery is made to save both halves of the double kidney in mechanic obstruction or vesicoureteral reflux in the accessory or basic ureter. The affected ureter is always removed under anastomosis. The interventions are indicated in anomalies causing ureteral obstruction, ureterohydronephrosis, vesicoureteral reflux, pyelonephritis. They are frequently performed in ectopic ureterocele of the accessory ureter, in vesicoureteral reflux associated with intravesical high ectopy of the basic ureter ostium and normal ostium of the accessory ureter, in low intra- and extravesical ectopy of the accessory ureter ostium. The authors have conducted 21 operations in 20 patients: bilateral transureteroureteral, 2 intrapelvic, 1 ureteropelvic and 18 transureteroureteral anastomoses. The surgery was decided upon because of ectopic ureterocele of the accessory ureter, ectopic ureterocele of the accessory ureter with vesicoureteral reflux via ureterocele, high ectopy of the basic and low ectopy of the accessory ureter ostia with reflux, low ectopy of the accessory ureters ostia. Short- and long-term outcomes of all the operations were good.
