Common risk factors in the development of hydronephrosis include renal calculi, external compression from abdominal and pelvic masses and tumors such as prostate enlargement and cancer, cervical cancer, diabetes mellitus and neurogenic bladder, congenital anomalies of the kidney and urinary tract (CAKUT) such as vesicoureteric reflux, ureteropelvic junction obstruction and posterior urethral valves.
