Currently, the incidence of stress urinary incontinence (SUI) in females is increasing year by year, and the disease has become one of the common diseases among middle-aged and old females in the world, exerting a great influence on their normal life, work, and social activities.At present, the consensus of domestic and foreign scholars on the treatment of this disease is that female patients with Grade III SUI, or patients with grade I-II ineffective conservative treatment should receive surgical treatment. The surgical treatment of SUI in females has gone through a hundred years of exploration, and the initial surgical method has a low cure rate and is prone to complications. In the past 20 years, with the invention and development of mid-urethral sling (MUS), the cure rate of SUI surgery in females has been obviously increased, but some patients still fail to effectively improve their symptoms or suffer from complications. The purpose of this paper is to summarize and analyze the effect of different MUS surgical procedures on female SUI and the influence of patients′ own factors on the surgical efficacy.
