Pancake kidney is a rare renal fusion anomaly with increased risk of complications, such as stone disease and infections, due to altered urodynamics. Image-guided (ultrasonography and fluoroscopy) percutaneous nephrostomy (PCN) is performed to decompress an obstructed pancake kidney. However, routine image guidance may be unable to provide a suitable access in complex clinical scenarios. The approach for PCN in a low-lying fused kidney is difficult due to a limited safe posterior retroperitoneal paraspinal route, and anterior transperitoneal approach poses risks of urine leak and peritonitis. We report a case of an obstructed pancake kidney managed by CT-guided PCN through a transiliopsoas approach.
