Malrotation of the Kidney
Definition of Renal Malrotation
The final position of the physiological kidney position in the renal fossa includes the rotation of the kidney with an orientation of the renal pelvis to the medial and the renal calyces to the lateral. Malrotation can be in any direction, with orientation of the pelvis anteriorly, posteriorly and laterally. Renal malrotation is frequent if other abnormalities are present.
Signs and Symptoms of Renal Malrotation
The majority of malrotated kidneys do not cause any symptoms. Due to changes in position, hydronephrosis or stone formation is the most common complication.
