Cystostomy is a commonly used method of urinary excretion in the clinical treatment of acute urinary retention and severe prostatic hyperplasia. Complications and management of cystostomy are as follows: a. Leakage of urine from the cystostomy opening, caused by the oversized cystostomy opening, the thin indwelling ureter, and the continuous leakage of urine down the ureteral gap. Patients can replace the thicker diameter ureter to make the gap between the ureter and the tissue smaller and reduce the symptoms of urine leakage. Second, urinary tract infection, because the bladder is connected to the outside world after the cystostomy, may be placed too long fistula infection of the bladder. Patients are advised to strengthen the disinfection at the fistula opening, give intravenous infusion of levofloxacin and strengthen anti-infection treatment. In most patients, the inflammation of the bladder can subside relatively quickly after 5-7 days and absorb on its own.
