    Abstract:
    Neurogenic lower urinary tract dysfunction (NLUTD) is a common urological disease that causes long-term complications and severely reduces patient's quality of life. Sacral neuromodulation has proven to be an effective treatment for NLUTD. However, most previous studies have focused mainly on the efficacy and safety of sacral neuromodulation in the treatment of NLUTD and less on the changes in urodynamic parameters in patients before and after sacral neuromodulation. This study aimed to evaluate the effect of short-term sacral neuromodulation on the results of video-urodynamic parameters in a 63-year-old woman with NLUTD with vesicoureteral reflux. The patient was admitted to the Department of Urology of Beijing Hospital in January 2021 and examined using video-urodynamics. In the same month, the patient underwent the first stage of sacral neuromodulation, with an experience period of 2 weeks. After the experience period ended, video-urodynamics was performed again in February 2021. By comparing the two video-urodynamic results, the effect of short-term sacral neuromodulation on the anatomy and physiology of the lower urinary tract was determined. After 2 weeks of sacral neuromodulation treatment, video-urodynamic parameter analysis showed that while the urine storage period of the patient significantly improved, the voiding period was not significantly changed. This was specifically reflected in the improvement of bladder compliance, safe capacity of the bladder, and significant reduction in vesicoureteral reflux. The improvement of the safe capacity of the bladder effectively helped the patient to control the number of intermittent catheterizations within an acceptable range, which greatly improved her quality of life. Therefore, the patient underwent permanent sacral neuromodulation implantation in February 2021. This study suggests that short-term sacral neuromodulation can significantly improve lower urinary tract function and reduce vesicoureteral reflux in patients with NLUTD with vesicoureteral reflux. In short, we believe that sacral neuromodulation may be a good choice for patients with NLUTD.
