Application of modified method in replacing urine-collecting bags among urethral stricture patients with indwelling catheter

Abstract

Objective To investigate the effect of modified method of replacing urine-collecting bags in urethral stricture patients with indwelling catheter.Methods One hundred and sixty patients were randomly assigned to experiment group and control group (80 patients in each group).Patients in experiment group were replaced urine-collecting bags by improved method. In control group,traditional method was used.The incidence of side-effect,awareness on indwelling catheter cautions,earlier recovery exercise of bladder function by correct pipe-griping method as well as the urine culture result were evaluated.Results None of patients in experiment group showed difficulty in decannulation,and there was statistical difference among two groups (0 vs 4,x2 =4.103,P ＜0.05).The positive rate of urine culture in experiment group was 7.50％ and it was significantly lower than that in control group (21.25％),and there was statistical difference among two groups (x2 =6.144,P ＜0.05 ).Awareness on indwelling catheter cautions in experiment group was superior to control group( P ＜ 0.05 ).Conclusions For patients indwelling catheter with complex urethral stricture,the application of improved method in replacing urine-collecting bags can reduce the incidence of side effects in indwelling catheter and alleviate patient' s discomfort. It makes the method of replacing urine-collecting bags more reasonable,and improves the quality of medical care and degree of patients' satisfaction.
