For female patients, catheterization also costs about$60, which is the rate for trying the most common catheterization. Female catheterization and male patient catheterization both require catheterization kits as well as catheterization charges. The catheterization kit is usually about$38 and the catheterization charge is about$12. For female patients, the perineum should be fully cleaned before catheterization, and disinfection should be given attention here, first from the outside to the inside, then from the inside to the outside, and then again to the urethral opening, so that local disinfection treatment can be carried out effectively. After catheterization, 300ml of urine should be exported and then effectively clamped and the residual urine in the bladder should be released gradually to prevent bleeding caused by catheterization.
