People who have only one kidney, who have immune system disorders such as diabetes or HIV, or who have had a transplant will need treatment right away.
People who have long-term hydronephrosis may need antibiotics to reduce the risk of UTI.
Loss of kidney function, UTI, and pain may occur if the condition is left untreated.
If hydronephrosis is not treated, the affected kidney may be permanently damaged. Kidney failure is rare if the other kidney is working normally. However, kidney failure will occur if there is only one functioning kidney. UTI and pain may also occur.
When to Contact a Medical Professional
Call your health care provider if you have ongoing or severe flank pain, or fever, or if you think you may have hydronephrosis.
Prevention of the disorders that cause this condition will prevent it from occurring.
