“…In all of our cases it was left open, with no adverse consequences. Since our patients did not have antenatal diagnosis, their medium age of treatment was 12 years, in contrast to that described in the literature (from six months to five years) (1,3,12,19). One of them had even been pregnant and had a normal delivery before duplex system with infrasphincteric ectopic ureter was diagnosed.…”

Purpose: Duplex system is one of the most common anomalies of upper urinary tract. Anatomical and clinical presentation determine its treatment. Usually, the upper moiety has a poor function and requires resection, but when it is not signifi cantly impaired, preservation is recommended. Laparoscopic reconstruction with upper pole preservation is presented as an alternative treatment. Materials and Methods: Four female patients with duplex system, one presenting with recurrent urinary tract infection and the others with urinary incontinence associated to infrasphincteric ectopic ureter, were treated. Surgical procedure envolved a laparoscopic ureteropyeloanastomosis of the upper pole ureter to the pelvis of the lower moiety, with prior insertion of a double J stent. Results: Surgical time varied from 120 to 150 minutes, with minimal blood loss in all cases. Follow-up varied from 15 to 30 months, with resolution of the clinical symptoms and preservation of the upper moiety function. Conclusion: Laparoscopic ureteropyeloanatomosis is a feasible and safe minimally invasive option in the treatment of duplex system. Laparoscopic ureteropyeloanastomosis in the treatment

“…Pyeloureteral duplication or duplex system is one of the most common anomalies of the upper urinary tract (1). Embryologically, a complete duplex system arises from two separate ureteric buds and is more common in girls than boys, in a ratio of 6:1.…”

“…Out of 63 children having duplicated systems, they observed that duplicated system was present unilaterally in 81% and bilaterally in 19% of children. 8 Whitaker and Danks also found unilateral duplication more common than bilateral duplication (6:1). 9 Rege VM et al believed bifid ureter was more common in females and was found to be present often on the right side.…”

Duplex collecting system is presence of two pelvicalyceal system which is associated with single or double ureter. Bifid ureter is one of the variations related to congenital anomalies of urinary system which are many times an incidental finding. A bifid ureter may be found in association with other congenital anomalies and defects. In the present case report, we present a case of bifid ureter with duplex collecting system and with no other associated congenital anomaly. The embryological and clinical correlations of duplex collecting system are discussed in present paper.
