Open pyelolithotomy in an ectopic kidney: A case report.

Renal ectopia with stone is a rare case with no specific reported incidence rate. The treatment of kidney stone in ectopic kidneys poses a challenge to urologists. A 48-year-old male presenting with colicky pain on the right flank since one year ago. CT urography revealed an right-crossed renal ectopia and hyperdense lesions (25 × 20 mm and 10 × 10 mm) in the ureteropelvic junction of the right kidney. Under general anesthesia, we performed open pyelolithotomy for the patient and removed two stones completely. Open surgery could be the choice for patients with complex stone burden and associated renal anomalies such as ectopic kidney.
