Abstract

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).

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 Figure 1: US findings: Right ovary within the normal size but with a complex solid mass. Left ovary with complex mass with a solid lesion measured 3 cm. Doppler negative.

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].
