PURPOSE Fetal hydronephrosis is a frequent finding due to advances in prenatal ultrasonography. The definition of fetal and neonatal urinary tract obstruction is a very difficult task requiring confirmation of reduced renal function and hydronephrosis. In this study we followed a series of consecutive patients with intrauterine hydronephrosis that persisted during post-natal life. METHODS 116...

A 4-year-old girl presented with progressive distension of the abdomen and bowing of the legs (genu valgum) since birth. She was anemic, with a blood pressure of 180/110 mmHg. The serum level of creatinine was 1.7 mg/dL. She had hypocalcemia, and elevated serum level of phosphorous and parathyroid hormones. Ultrasonography revealed bilateral grossly hydronephrotic kidneys with thinned out paren...
