Renal pelvis stone in reverse kidney: A case report and literature review.

In neonates, kidney and urinary tract anomalies, like rotation anomalies, may be observed at rates of 3-11%. During rise to the lumbar region, the kidney completes rotation from left to right around the long axis from top to bottom and the renal hilum turns toward the medial direction. However, generally due to vascular causes, this rotation around the long axis of the kidney (renal axis, pole to pole) may be incomplete or may not occur. In this case report, we present a 45-year old male patient with stone in a kidney with renal hilum facing fully lateral.
