Bilateral hydronephrosis oocurs when urine is unable to drain from the kidney down the ureters into the bladder. Hydronephrosis is not itself a disease, but rather a physical result of whatever disease is keeping urine from draining out of the kidneys, ureters, and bladder.
Disorders associated with bilateral hydronephrosis include:
Signs of hydronephrosis is generally seen during pregnancy ultrasound studies 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.
