The spectrum of ureteropelvic junction obstructions occurring in duplicated collecting systems.
The authors reviewed four cases of ureteropelvic junction obstruction (UPJ) in duplicated systems. Associated abnormalities included contralateral duplication, vesicoureteral reflux, and a case of ipsilateral upper pole ectopic ureter with a dysplastic upper pole moiety. Surgical management included dismembered pyeloplasty, ureteral reimplantation, end-to-side pyeloureterostomy to the upper-pole ureter, and upper-pole heminephrectomy with lower-pole dismembered pyeloplasty. UPJ obstructions occurring in duplicated systems often are associated with other anomalies.
