Objective To explore the effect of comprehensive rehabilitation management of bladder function on neurogenic bladder after spinal cord injury.Methods Seventy-two patients with neurogenic bladder after spinal cord injury admitted to our hospital from January 2018 to December 2021 were randomly divided into an observation group of 36 cases and a control group of 36 cases.The control group was given routine nursing intervention,including indwelling catheterization,psychological counseling,etc.The observation group,based on the control group,adopted comprehensive rehabilitation management of bladder function,including intermittent catheterization,drinking water planning,and bladder function training.All patients of both groups were observed for 4 weeks.The urination status of the two groups was compared,including the average urine volume per time,the average number of urination per day and the residual urine volume.The bladder function indicators after 4 weeks of intervention were observed,including maximum manometric volume(MCC),maximum urine flow rate(MFR)and the incidence of urinary tract infection.And the effectiveness of treatment for neurogenic bladder after 4 weeks was compared.Results The average urine volume per time in the observation group was significantly higher than that in the control group(P<0.01),and the average number of urination and residual urine volume per day were significantly lower than those in the control group(P<0.01).MCC and MFR in the observation group were significantly better than those in the control group,and the incidence of urinary tract infection was significantly lower than that in the control group(P<0.01);The cure rate of neurogenic bladder in the observation group was higher than that in the control group(P<0.05).Conclusion Comprehensive rehabilitation management of bladder function for patients with neurogenic bladder after spinal cord injury can improve the patients'urination disorder,promote the recovery of bladder function,reduce the incidence of urinary tract infection,and improve the quality of life
