The abnormalities of the renal collecting system represent a complex subset of urogenital anomalies. They could manifest in many ways and often are not diagnosed by preoperative imaging or the anomaly could be missed. Extrarenal calyces is one such rare anomaly of the collecting system. This anomaly may be associated with other anomalies of the urogenital system such as hydronephrosis, ectopic kidney or horseshoe kidney and could lead to complications such as stasis, infection and stones. We report a case of ectopic kidney with extra-renal calyces complicated with stones and infection.
