Renal ptosis, also known as nephroptosis, is a condition in which one or both kidneys descend lower than their normal position in the abdomen. This typically occurs when the supporting ligaments that hold the kidneys in place stretch or weaken. Nephroptosis can be caused by various factors, including genetic predispositions, trauma, or physical exertion. Symptoms may include back pain, but often there are no characteristic symptoms. In more severe cases, renal ptosis can lead to complications such as hydronephrosis or urinary tract infections.

The diagnosis of renal ptosis usually begins with a medical examination and history taking. Additional tests such as kidney ultrasound, CT scans, or intravenous urography may be required to confirm the diagnosis. These tests help doctors determine the exact position of the kidneys and assess the degree of ptosis.

Nephropexy is a surgical procedure used to correct renal ptosis. During this procedure, the surgeon repositions the kidney to its normal location and secures it in place to prevent further descent. This can be achieved using various techniques and fixation materials, including meshes or supports. After nephropexy, patients typically experience relief from symptoms and a reduction in the risk of complications associated with renal ptosis.
