A ureteral stent, which allows the ureter to drain, or nephrostomy tube, which allows the kidney to drain through the back, bypassing the ureter, will provide temporary relief of the obstruction. However, the underlying cause must be treated to cure this condition.
If signs and symptoms of an infection are present, antibiotics and prompt relief of urinary obstruction is mandatory. Patients who have only one kidney, who have immune-compromising disorders such as diabetes or HIV, or who have received a transplant should be treated promptly.
If hydronephrosis is chronic, preventive antibiotics may be prescribed to decrease the risk of urinary tract infections.
