Abstract

Crossed renal ectopia is a rare congenital anomaly that is frequently associated with gastrointestinal, cardiovascular, genital, and bone malformations. To best of our knowledge, there aren't many cases of inferior crossed fused renal ectopia of the right kidney documented in the literature at this time. A case of crossed-fused renal ectopia is presented here. A 32-year-old man arrived at our hospital complaining of pain in the right flank. Diagnosis: We suspected a single right kidney based on abdominal ultrasonography. An inferior left to right crossed-fused ectopic kidney with calculus in the right (normal) renal pelvis was the patient's diagnosis when combined with 3D computed tomography. Interventions: percutaneous nephrolithotomy with DJ stenting. Because the management of renal stone in this uncommon malformation is complicated, a preoperative assessment with contrast computed tomography is required before moving forward with surgery in order to explore a single kidney with calculi and avoid missing the diagnosis of crossed fused renal ectopia.
