Nephroptosis (also called floating kidney or renal ptosis) is an abnormal condition in which the kidney drops down into the pelvis when the patient stands up. It is more common in women than in men. It has been one of the most controversial conditions among doctors in both its diagnosis and its treatments.

Cause

It is believed to result from deficiency of supporting perirenal fasciae.

Symptoms

Nephroptosis is asymptomatic in most patients. However, nephroptosis can be characterized by violent attacks of colicky flank pain, nausea, chills, hypertension, hematuria and proteinuria. Patients with symptomatic nephroptosis often complain of sharp pains that radiate into the groin. Many patients also suggest a weighing feeling on the abdomen. Pain is typically relieved by lying down. The attack of colic pain is called 'Dittel's crisis' or 'renal paroxysm'.

Diagnosis

Diagnosis is contemplated based upon patient symptoms. Diagnosis is confirmed during intravenous urography, by obtaining erect and supine films. The renal DMSA scan may show decreased counts in the sitting position compared with supine scan.

Treatment

Nephropexy was performed in the past to stabilize the kidney, but presently surgery is not recommended in asymptomatic patients. Laparoscopic nephropexy has recently become available for selected symptomatic patients.

Comparative evaluation of hemodynamics in patients with chronic pyelonephritis and symptomatic hypertension in abnormal renal mobility depending on the distribution on the degree of rotation and skeletotopic omission of kidney was performed. According to the data of frequency analysis and correspondence analysis of Statistics 6.0 program, it was determined that kidney rotated in three dimensions, and mainly in II degree descent kidney in study group. It was found that consistent multiple view scanning of patients with abnormal renal mobility allows to accurately assess the violations of tissue blood flow, which determine severity of complications of the disease, and to choose an adequate conservative and surgical treatment in each case.
