Urinary Incontinence Catheters. A catheter is a long, thin tube inserted up the urethra or through a hole in the abdominal wall into the bladder to drain urine (suprapubic catheter). Draining the bladder this way has been used to treat incontinence for many years. Bladder catheterization may be a temporary or a permanent solution for urinary incontinence. In cases of overflow incontinence resulting from obstruction, some people respond well to temporary continuous Foley catheter drainage.
