A suprapubic catheter (SPC) is a hollow, flexible silicone tube placed directly into the bladder through a small opening in the lower abdomen, a few inches below the navel. A small balloon at the tip of the catheter is inflated inside the bladder to hold the catheter in place. Urine drains continuously into a bag, or into the toilet via a catheter valve.
The first suprapubic catheter is placed by a urologist in the operating room or procedure suite under local anesthesia with sedation, or under a brief general anesthetic. After it has been in place for several weeks and the tract is well established, the catheter can be changed at home or in clinic on a regular schedule.
