Extrarenal calyces in a pelvic kidney with ureteropelvic junction obstruction in an adult male – A rare case report

Abstract

Extrarenal calyces (ERC) is a rare renal anomaly. First described in 1925, and till now, >60 cases have been reported worldwide. The association of ERC in ectopic kidneys with ureteropelvic junction obstruction (UPJO) is a very rare presentation. We encountered a case of an adult male with ERC in a pelvic kidney with UPJO, in which the dilated ERC mimicked the ureter and created intraoperative confusion.
