Ureteral triplication combined with right renal ectopia and ureteral cyst.

Ureteral triplication is one of the rarest malformations of the upper urinary tract. We report the case of a 12-year-old girl with right ureteral triplication combined with renal ectopia and ureteral cyst with stenosis at the junction of the ureteral cyst and distal ureter. The ureteral cyst was tailored and tubularized, and the tight junction was removed, as in Hynes-Anderson ureteropyeloplasty; on reevaluation almost 4 years later, kidney function was normal and computed tomography showed a normal kidney and ureter.
