Case 1: 24-year-old female complaining of fever and back pain. Excretory urography disclosed absence of left kidney and right hydronephrosis due to UPJ stricture. The lower calyx was tapering into the renal pelvis and the infundibula of the other major calyces were not visualized. A diagnosis of extrarenal calyces was made at pyeloplasty.
Case 2: 28-year-old female having recurrent acute pyelonephritis. Excretory urography showed bilateral hydroephrosis due to UPJ stricture. The minor calyces were few in number and pyelectasis was milder than calyectasis. The left renal pelvis was distended longitudinally, branching out into the major calyces like a rake. The diagnosis of bilateral extrarenal calyces was confirmed at pyeloplasty.
Case 3: 34-year-old female complaining of left flank pain. Excretory urography showed left hydronephrosis due to UPJ stricture. The upper major calyces was elongated and the infundibula of the other major calyces were not visualized. Pyeloplasty settled the diagnosis of extrarenal calyces.
Including our 3 cases, a total of 28 cases of extrarenal calyces have been reported in the world literature. Combined anomalies, X-ray findings and clinical significance of this anomaly are discussed.
