摘　　要：<strong>Objective:</strong> To evaluate the efficacy and safety of Combined detrusor and external urethral sphincter BTX-A injections for detrusor overactivity (DO) and detrusor external sphincter dyssynergia (DESD) secondary to spinal cord injury. <strong>Study Design:</strong> Prospective study. <strong>Methods:</strong> The study was carried out in 18 SCI patients with detrusor overactivity (DO) and detrusor external sphincter dyssynergia (DESD) receiving Combined detrusor and external urethral sphincter BTX-A injections treatment. Contain 200 U botulinum toxin intradetrusor and 100 U external urethral sphincter injections. The effective outcomes included maximum detrusor pressure at first DO and DESD (PdetmaxDO-DESD), volume at first DO and DESD (VDO-DESD), maximum urethral closure pressure (MUCP), and Incontinence-Specific Quality-of-Life Instrument (I-QoL). Adverse events were recorded. <strong>Results:</strong> All patients experienced a significant mean reduction in PdetmaxDO-DESD (50.75%), maximum urethral closure pressure (26.34%) and a significant mean increase in VDO-DESD (63.00%) 12-weeks post-injection. Significant (p < 0.001) improvement in mean Incontinence-Specific Quality-of-Life Instrument was also found. No obvious adverse event and toxic effect was observed. <strong>Conclusion:</strong> Combined detrusor and external urethral sphincter BTX-A injections is a good choice for patients with DO and DESD secondary to spinal cord injury. It could not only protect the upper urinary tract but also improve quality of life.<strong>Objective:</strong> To evaluate the efficacy and safety of Combined detrusor and external urethral sphincter BTX-A injections for detrusor overactivity (DO) and detrusor external sphincter dyssynergia (DESD) secondary to spinal cord injury. <strong>Study Design:</strong> Prospective study. <strong>Methods:</strong> The study was carried out in 18 SCI patients with detrusor overactivity (DO) and detrusor external sphincter dyssynergia (DESD) receiving Combined detrusor and external urethral sphincter BTX-A injections treatment.
