Some patients experience urinary retention after surgery, which may make a catheter necessary even if the patient did not need one during the procedure. Patients may also experience urinary retention after the removal of a Foley catheter.
Catheters can be inserted into a body cavity, duct, or vessel. Functionally, they allow drainage, administration of fluids or gases, access by surgical instruments, and also perform a wide variety of other tasks depending on the type of catheter. The process of inserting a catheter is catheterization. In most uses, catheter is a thin, flexible tube (soft catheter) though catheters are available in varying levels of stiffness depending on the application.
