Objective: To evaluate usefulness and safety of an indwelling contemporary balloon catheter, we compared complication rates among five methods of urinary tract management.
Patients and methods: History of febrile episode, bladder stones, pyuria and the miscellaneous urinary tract problems of 114 patients were retrospectively reviewed. The rates of complications were compared among five types of urinary tract management as clean intermittent catheterization dry (not incontinent) (CIC-dry: n = 33), clean intermittent catheterization with incontinence (CIC-wet: n = 16), clean intermittent catheterization with a contemporary balloon catheter indwelling at night (Contemporary catheter: n = 20), a suprapubic cystostomy catheter indwelling (Cystostomy: n = 22) and permanent urethral balloon catheter indwelling (Urethral catheter: n = 24). The contemporary balloon catheter used consisted of a reusable balloon catheter and a reservoir to inflate the balloon. The patients in the Contemporary catheter group self-inserted the catheter every night before sleeping, and then removed it in the next morning. After use, the catheter was washed with tap water, and stored in a special purpose case filled with disinfectant.
Results: The mean follow up period was 41 months. The incidence of febrile episode in CIC-wet was 3.36 times/100 months, Urethral catheter was 2.96, Cystostomy was 1.26, Contemporary catheter was 0.57, and CIC-dry was 0.42. The incidence of febrile episode in CIC-wet and Urethral catheter were significantly higher than in CIC-dry (p<0.05). The incidence of bladder stone in Urethral catheter was 1.11 times/100 months, Cystostomy was 1.05, Contemporary catheter was 0.96, CIC-wet was 0.61, and CIC-dry was 0.21. The Urethral catheter group had significantly higher incidence of bladder stone than CIC-dry (p<0.05).
Conclusions: The indwelling contemporary balloon catheter is recommended for long-term use in CIC-wet group.
