different types of catheters urinary
Catheter insertion is performed by placing the catheter into the urethra and allowing urine to drain from the bladder freely and may be attached to an external urine collection bag to store the urine. There are primarily three types of catheters: â¢ Indwelling or foley catheters. â¢ Intermittent catheters. â¢ External catheters. Indwelling or foley catheters are flexible tubes placed into the bladder to drain urine. Patients who require long-term catheterization use them.
