Ureteral Triplication, Occasionally an Isolated Anomaly

Abstract

A case of isolated ureteral triplication is presented, the patient did not have any other urogenital anomaly. This presentation is rare and relevant literature is discussed.

A case of ureteral triplication associated with ureteropelvic junction obstruction

“…Ureteral triplication is a rare congenital anomaly of the ureter [1,2,[4][5][6][7][8][9]. It is a developmental abnormality of the ureteral bud originating from the Wolffian duct at the 50 week of embryological life [1].…”

“…It grows dorsally at first and cranially later and makes contact with the metanephros and the distal end differentiates into the renal pelvis and the major and minor calyces during the 6th-8th weeks. In triplication of the ureter three ureteral buds could arise independently from the mesonephric duct, or from early fission of one or more ureteral buds to join the metanephros [2,5,8,9].…”

Ureteral Triplication Associated with Ipsilateral Ureterocele and Ureterolithiasis - Uncommon Congenital Anomaly

“…Ureteral duplication occurs in 0.3-0.8% of the population, but ureteral triplication has been very rarely described [2]. The most frequently encountered anomalies with ureteral triplication are contra lateral duplications (37%), renal ectopia (28%) and renal dysplasia (8%) [3].…”

Ureteral Triplication And Contralateral Duplication With Vesicoureteral Reflux

“…Only 5 cases of bilateral ureteral triplication have been reported (6). Furthermore, ureteral triplication is occasionally an isolated anomaly (7). It has been reported in the literature that ureteral triplication may be complicated with contralateral ureter duplication, vesicoureteral reflux, ureterocele, crossed ectopic fused kidneys, ureteropelvic obstruction and duplication of the bladder (6,8).…”
