Ureteroptosis is a medical condition characterized by the abnormal downward displacement or prolapse of the ureter, which is the tube that carries urine from the kidney to the bladder. This condition can lead to urinary obstruction and may result in complications such as hydronephrosis, where the kidney becomes swollen due to the accumulation of urine. Ureteroptosis can occur due to factors like congenital abnormalities, trauma, or significant weight loss. Treatment often involves addressing the underlying cause and may include surgical intervention in severe cases.
