Sacral nerve magnetic stimulation combined with rehabilitation training in the treatment of primary nocturnal enuresis in children

Objective: To explore the clinical value of sacral magnetic stimulation (SMS) combined with rehabilitation training in the treatment of primary nocturnal enuresis (PNE) in children. Methods: The clinical data of 57 children with PNE admitted to the Department of Rehabilitation Xuzhou Rehabilitation Hospital, Xuzhou Central Hospital and Xuzhou Children's Hospital from October 2019 to September 2020 were collected and analyzed. The children were divided prospectively into observation group and control group by using random number table method. Bladder function training, awakening training and life and psychological intervention were performed in both groups, while the observation group was treated with SMS based on the above treatment methods. Before and after treatment, the degree and the frequency of enuresis (normal, mild, moderate, severe), therapeutic evaluation and bladder volume were compared. Chi-square test and T test were used for comparison between the two groups. Results: Finally, 28 cases in the observation group and 29 cases in the control group were included. There was no significant difference in age, sex, degree and of frequency enuresis of children between the two groups (all P>0.05).The degree of enuresis in the observation group after 1 month of treatment was better than that in the control group (12 vs. 7 cases, 8 vs. 8 cases, 5 vs. 9 cases, 3 vs. 5 cases, χ2=-2.269, P=0.030). Enuresis times in observation group was lower than that in the control group [(4.2±1.8) vs. (8.1±2.0), t=4.475, P<0.01). The total effective rate and bladder capacity of efficacy evaluation were higher than those of control group [82%(23/28) vs. 48%(14/29), (225±25) vs. (199±21) ml, Z=11.238, t=-2.249, both P<0.05]. Conclusions: SMS is an effective method for the treatment of PNE in children, which can reduce the degree and frequency of enuresis in children, increase the bladder volume and improve the total effective rate of treatment. It is worthy of clinical promotion and application.
