Malrotated Ectopic Kidney with Hydronephrosis: A Case Report

Congenital renal anomalies cover a significant portion of abnormalities, which may be due to variations in number, position, shape, and size of the kidney(s). Most studies are based on structural, local, and vascular abnormalities, while few of them, to the best of our knowledge, were conducted on abnormal renal rotation (renal malrotation).

The patient was a 25-year-old woman who presented with right kidney pain with a history of pain in the same area. Examinations and tests were normal. The patient underwent retrograde pyelography. The right and the left kidneys were observed with excessive rotation and below the normal location, and severe hydronephrosis, respectively.

Ectopic kidneys are accidentally diagnosed and are prone to complications such as hydronephrosis, kidney stones, Urinary Tract Infections (UTI), and urologic problems.
