Inverted Y Ureteral Duplication with Distal Obstructing Calculi in the Ectopic Ureter in the Prostatic Urethra and Duplex Kidney

Abstract

Duplication of the ureter and renal pelvis is a relatively common congenital anomaly with an incidence of approximately 1 in 150 births. Different anatomical variations of ureteric duplication exist. Ectopic ureters are usually associated with ureteral duplication and a duplex collecting system. Duplication of the ureter is more common unilaterally, has a female preponderance, and occurs more commonly on the left side. We present the case of a 58-year-old male with inverted Y ureteral duplication who had distal obstructing ureteric calculi in the ectopic distal ureteral opening in the prostatic urethra.
