Your treatment will depend on what's causing the condition and how severe it is. the first stage of treatment is often to drain the urine out of your kidneys by inserting a tube called a catheter into your bladder or kidney(s). This will help relieve the pressure on your kidneys. Once the pressure has been relieved, the cause of the build-up of urine may need to be treated. The treatments used will depend on why the condition developed.
