The female patient with a catheter

Catheters are measured in 'French' gauge (Fg) or 'Charriere' (Ch). Catheters used in women should range from size 12Ch to 16Ch, with a 10ml balloon. Catheters can be either connected to a drainage bag or a valve. Whenever possible, intermittent catheterization should be taught to patients to facilitate bladder emptying. Long-term indwelling catheterization should be a last resort as 'treatment' for women with lower urinary tract dysfunction.
