Open Pyelolithotomy with Concurrent Percutaneous Nephrolithotomy in a Patient with an Ectopic Pelvic Kidney

Introduction: The pelvic kidney is a rare anomaly that is prone to stone formation due to its abnormal position. Performing minimally invasive procedures can be risky because of the abnormal anatomy and uncertain blood supply of these kidneys.Case Presentation: In this study, we present a 43-year-old man who had an 8-cm stone in the right ectopic pelvic kidney concurrent with an obstructive stone in his left kidney. He underwent simultaneous open pyelolithotomy of the right pelvic kidney and percutaneous nephrolithotomy of the left kidney at one stage.Conclusion: If possible, surgery for pelvic kidney stones should be performed using minimally invasive techniques. But in some cases, reasons such as the abnormal position of the kidney and the possibility of damage to the surrounding organs as well as the size of the stone can make open surgery unavoidable.
