Hydronephrosis - bilateral

Signs of hydronephrosis is generally observed during routine fetal ultrasound studies done during routine pregnancies and as such there are no symptoms in the fetus.

In the newborn, any diagnosed urinary tract infection is reason to suspect some type of obstructive problem in the kidney. In the older child, repeat urinary tract infections are cause for evaluation of possible obstruction.

Unfortunately, with the exception of an increased number of urinary tract infections, obstruction of the urinary tract is often without symptoms.

Bilateral hydronephrosis may be apparent on:

• IVP
• Renal scan
• Ultrasound of the abdomen or kidneys
• CT scan of the abdomen or kidneys
