A<unk>  or<unk>  catheter (SPC) (also known as a vesicostomy or epicystostomy) is a surgically created connection between the urinary bladder and the skin used to drain urine from the bladder in individuals with obstruction of normal urinary flow. The connection does not go through the abdominal cavity. Urinary flow may be blocked by swelling of the prostate (benign prostatic hypertrophy), traumatic disruption of the urethra, congenital defects of the urinary tract, or by obstructions such as kidney stones passed into the urethra, and cancer. It is also a common treatment used among spinal cord injury patients who are unable or unwilling to use intermittent catheterization to empty the bladder, and cannot otherwise void due to detrusor sphincter dyssynergia. Initially, a thin tube (catheter) is placed through the skin just above the pubic bone into the bladder, often with the assistance of ultrasound imaging. This catheter initially remains in place for up to a month while the tissue around it scars and forms a tract (sinus) between the bladder and the body exterior. After the formation of scar tissue is complete, the catheter is replaced periodically in order to help prevent infection.
