Clinical evaluation of the multifunctional suprapubic catheter in patients requiring permanent suprapubic cystostomy: A prospective randomised trial in a single centre

摘要

Aims and objectives To assess the clinical effect of the multifunctional suprapubic catheter (MSC) on occurrence of cystospasm, catheter occlusion, the catheter-related urinary tract infection and remission of overactivity bladder, by comparing with the conventional suprapubic catheter (CSC) in patients with permanent suprapubic cystostomy. Background The conventional suprapubic catheter usually presents with high incidence of catheter-associated complications. Design A prospective randomised clinical trial in a single centre. Methods Between January 2014 and January 2015, a total of 91 consecutive patients with permanent suprapubic cystostomy were prospectively randomised into two groups: the MSC group (n = 43) and CSC group (n = 48). Results Our results showed that the total times of cystospasm in the MSC group were significantly less than that in the CSC group during the follow-up time (p < .001). In addition, the mean spasmodic duration per time in the MSC group was significantly shorter than that in the CSC group (p < .001). Besides, catheter occlusions were observed in 23 (25.27%) patients, including 5 (11.63%) in the MSC group and 18 (37.50%) in the CSC group (p = .005). The lower rate of positive urine culture was also found in the MSC group but with no significant difference (p = .540). Furthermore, the urodynamic measurement data demonstrated that the patients in the MSC group had a greater remission rate of overactivity bladder after catheter change (p < .001). Conclusions The present data showed that the multifunctional suprapubic catheter could significantly reduce the incidence of catheter occlusion, ameliorate the symptom of cystospasm and relieve the overactivity bladder, but have no influence on the catheter-related urinary tract infection. Relevance to clinical practice The application of our self-devised multifunctional suprapubic catheter may result in better management of the patients with permanent suprapubic cystostomy.
