[Study on prevention of catheter associated urinary tract infection by using JUS long-acting antibacterial material]

To observe the effect of reducing the incidence of CAUTI by spraying the long-acting antibacterial material JUS on the surface of catheter and urethral orifice.

Sixty male patients, aged from 68 to 79, with indwelling catheter after TURP were divided randomly into two groups (control group and treated group), each consisting of 30 patients. For the control group, their urethral orifice was treated conventionally twice a day; while for the treated group, in addition to the conventional treatment of their urethral orifice, the catheter and their urethral orifice were sprayed with the long-acting antibacterial material JUS twice a day.

The number of cases of urinary tract infection in the treated group during catheterization was evidently less than those of the control group (P < 0.01), so the difference was of remarkable significance.

The long-acting antibacterial material, after spraying on the wall of catheter and urethral orifice of the patients with indwelling catheter, may form a layer of physically antibacterial molecular film to prevent the formation of a bacterial biological film and effectively reduce the incidence of CAUTI.
