Size up, not down, when choosing a catheter for a man

When a male patient is in need of a catheter, "Bigger is better for boys." For example, if a patient has known benign prostatic hyperplasia and you try an 18F catheter without luck, go a size or two bigger rather than smaller. The larger catheter is stiffer and can pass through the prostatic urethra more easily. — Charlene Kreiensieck, PA-C, Laconia, N.H. (158-16)
