- Hydronephrosis occurs
when an obstruction to the normal urinary flow (from kidney
to bladder) creates backup pressure, causing the urine to
flow upward toward the kidney, while distending the pelvis
and calyces of the unilateral kidney.
- Kidney Stones, Bladder Stones, or stones in the ureters; tumor (of the ureter); cancers of the structures surrounding the ureters or bladder (e.g., cervix); strictures of the ureter present at birth; neurogenic bladder; and bladder neck obstruction can all increase the risk for Hydronephrosis.
- Symptoms may range from abdominal or flank pain, to abdominal mass, Hypertension, and
kidney failure.
- Surgery may be needed to relieve the problem.
