Objective To evaluate the effectiveness and safety of sacral neuromodulation(SNM) in the treatment of non-neurogenic and non-obstructive dysuria in elderly patients.Methods Six elderly patients with non-neurogenic and non-obstructive(2 males and 4 females)treated with SNM were recruited from multiple medical centers across the country in this retrospective study from January 2012 to December 2016.All patients received two or more conservative treatments including behavior therapy,oral therapy,etc.,with no good effect.Data of the average residual urine volume,average urine volume,maximum urine volume,average urinary frequency and quality of life score before operation,after implantation of stage Ⅰ tined lead,and at the end of follow-up after implantation of stage Ⅱ implanted pulse generator(IPG) were compared.Results The average age in the 6 patients was 69.5 (65 ~ 79) years.The results of SNM treatment showed that the objective findings and/or subjective symptoms in all patients were significantly improved in more than 50% of indexes before treatment.All patients chose embedding of IPG at the end of stage Ⅰ,with 100.0% of the conversion rate from stage Ⅰ to stage Ⅱ.The curative effect was stable in general.At stages of baseline,personal experience and end of follow-up respectively,the average residual urine volumes were (161.7±110.2)ml,(70.0±52.2) ml,and(50.0±44.7)ml,the average urine volume were(105.0± 74.0)ml,(163.3 ± 93.1) ml,and (155.0 ± 92.3) ml,and the maximum urine volume were (146.7 ± 81.2) ml,(216.7 ± 93.1) ml,and (206.7 ± 112.7) ml,which showed continuously significant improvements with patients' great satisfaction.The mean duration of fellow-up in 6 cases was 17.5 months(7-57 months).No severe adverse reactions such as wound infection,electrode dislocation and hematoma were observed.Conclusions SNM treatment is safe and effective for elderly patients with non-neurogenic and non-obstructive dysuria who are refractory to other treatments.SNM has a stable medium-term curative effect and a high-transfer-rate from stage Ⅰ to stage Ⅱ,which is appropriate for non-neurogenic and non-obstructive dysuria.The duration of SNM may be positively correlated with the improvement of residual urine volume and urination frequency.
