Sacral nerve stimulation (SNS).
Using an electric stimulator (similar to a pacemaker) under your skin, your doctor can zap your sacral nerve with electric pulses. This can help calm bladder spasms.
If your urethra has a hole that’s letting urine leak, your doctor can inject it with material (like collagen). This material will build up the urethra wall thickness, filling empty space, and creating extra resistance. Your doctor uses a needle through the skin or directly into the urethra to do it. You may need general anesthesia during the procedure.
When you can’t get all the urine out of your bladder on your own, your doctor may want you to use a catheter to help things along. A catheter is a soft, thin tube you insert into the tip of your penis. Your doctor may ask you to do this several times a day, or you may use a catheter that can stay in your urethra all the time.
