Selective injection allows specific paralysis of the detrusor muscle, which alleviates common urologic conditions, including neurogenic hyperreflexia and overactive bladder. 选择性的注射可以特异性的松弛逼尿肌，舒缓普遍的泌尿道问题，包括神经原性的反射亢进和膀胱无力。
Other commonly used terms such as detrusor instability and detrusor hyperreflexia refer to involuntary detrusor contractions observed during urodynamic studies. 比如逼尿肌反射亢进或是逼尿肌功能不稳定都能导致逼尿肌收缩。
