Surgery to repair a bladder fistula can be successful if enough healthy tissue is available to close the area of the fistula. After surgery, you will face several weeks of recovery. For a few weeks following surgery, you will be required to have an indwelling (inside the body) catheter in place while your bladder heals. This catheter is a tube that allows urine to flow directly from the bladder and out of the body through the tube. Care of the catheter is very important. It should be kept clean, according to your doctor's instructions. The skin around the catheter must also be cared for, kept clean, and remain free of powders and lotions.
