bilateral or unilateral, and different defects often coexist in
an individual patient [1].
Complete or partial duplication of the renal collecting
system also referred to as a duplicated system, is the
most common congenital anomaly of the urinary tract [2].
Autopsy studies report an estimated incidence of 0.8 to 5.0
percent [3]. Double collecting systems are thought to result
from duplication of the ureteric bud, with the superior bud
associated with the upper renal pole, and the inferior bud
with the lower renal pole.
In complete duplication, the kidney has two separate
pelvicalyceal systems and two ureters. The ureter from the
lower collecting system usually enters the bladder in the
trigone, whereas the ureter from the upper collecting system
A 27-year-old, gravida 0 para 0, female presented herself
for an evaluation of recurrent urinary tract infections and
severe dysmenorrhea. The ultrasound revealed a bilateral
small but complex adnexal mass, suggesting endometriosis
(Figure 1). Ca 125 was 88 U. Laparoscopic surgery was
performed, showing evidence of infiltrative endometriosis
and entrapment of the right ureter on the right pelvic
sidewall (Figure 2); During the initial anatomical inspection a
duplicated ureter was diagnosed (Figure 3). The laparoscopic
surgery was performed to liberate both ureters and resection
of the deep endometriosis without any complicated issues
(Figure 4).
Congenital anomalies of the kidney and the urinary tract
(CAKUT) constitute approximately 20 to 30 percent of all
anomalies identified in the prenatal period. Defects can be

can have a normal insertion in the trigone, or it can be inserted
ectopically in the bladder or elsewhere. Ectopic insertion of
the ureter can result in obstruction or vesicoureteral reflux
(VUR) [4]. Depending on the location of the ectopic insertion,
incontinence also may be present.
Partial duplication is more common than complete
duplication. In these cases, the kidney has two separate
pelvicalyceal systems, with either a single ureter or two
ureters that unite prior to insertion into the bladder. Strong
knowledge of the retroperitoneal anatomy will facilitate the
ureteral findings [5].
In patients with asymptomatic uncomplicated (no dilation)

or referral is needed. However, if there is a history of urinary
tract infection (UTI) or dilation (typically due to obstruction)
further interventions must be done, this can be done with
laparoscopic surgery.
