Pyeloureterostomy in the management of the lower pole pelvi-ureteric junction obstruction in incomplete duplicated systems.
OBJECTIVE
To report our experience with the pyeloureterostomy (PU) for the treatment of the lower pole PUJO in incomplete duplex systems. The combination of the duplicated collecting system and pelviureteric junction obstruction (PUJO) is a rare association and infrequently reported. Surgical treatment can be challenging in such cases.


METHODS
We retrospectively reviewed the medical data of the patients who had surgery from 2001 to 2009, with a diagnosis of PUJO of the lower pole moiety in incomplete duplex system. Demographic, diagnostic, and procedural data were recorded.


RESULTS
Seven patients were identified with the lower pole PUJO associated with incomplete duplex systems. Their median age was 49 months (range 2-108 months). Prenatal hydronephrosis was detected in 3 patients, and 4 had a febrile urinary tract infection. PU was performed in 6 patients because of short ureteral length between the ureteropelvic junction and junction of lower and upper pole ureters. One patient was treated with the dismembered pyeloplasty because of sufficient ureteral length of the lower pole. No complications were detected during 14 months of follow-up.


CONCLUSIONS
The management of the lower pole PUJO in incomplete duplex systems should be individualized for every patient. PU is a good surgical option in the management of the lower pole PUJO associated with incomplete ureteral duplication.
