Nephroptosis is a rare condition where the kidney drops into the pelvis when standing due to deficient supporting tissues. It is usually asymptomatic but can cause colicky flank pain, nausea, chills, high blood pressure, blood in the urine, and protein in the urine. Diagnosis involves patient symptoms and X-rays of the kidney in both upright and lying positions. Surgery to stabilize the kidney is no longer recommended for asymptomatic patients.
