Effect of different traction weight on preventing leakage of urine in elderly patients with indwelling urethral catheterization

Objective To explore the appropriate traction weight of traction method for the prevention of leakage of urine in elderly patients with indwelling urethral catheterization so as to provide a theoretical basis for clinical work. Methods A total of 120 indwelling urethral catheterization patients with leakage of urine in department of geriatrics of Jiangdu People's Hospital of Yangzhou (affiliated Hospital of School of Medicine, Yangzhou University) were selected by convenient sampling from January 2014 to August 2016. They were randomly divided into four groups and accepted traction method for the prevention of leakage of urine involving traction weight with 50, 100, 150, 200 g. The preventive effect and situation of comfort of patients were compared among four groups. Results The effective rate in prevention of leakage of urine of traction weight with 50, 100, 150, 200 g was 16.7%, 100%, 100%, 100% with a statistically significant difference among four groups with different traction weight (Hc=73.849, P<0.001) . The results of intercomparsion showed that the effects of groups with traction weight of 100, 150, 200 g were statistically better than that of the group with traction weight of 50 g (χ2 = 42.857, P<0.001) . There were statistically significant differences in degree of comfort among four groups with different traction weight (Hc=57.674, P<0.001) . Compared with the group with traction weight of 150 g, the incidence of moderate or severe discomfort was 70% in the group with traction weight of 200 g with a significant difference (χ2=19.817, P<0.001) . There was no statistically significant difference in the incidence of moderate or severe discomfort between the group with traction weight of 100 g and 150 g (χ2= 0.162, P=0.688) . Conclusions The optimum traction weight for the prevention of leakage of urine in elderly patients with indwelling urethral catheterization is 100-150 g.
