Objective: To introduce a urodynamic classification of male patients with symptoms of overactive bladder (OAB) and discuss its clinical significance in practice.Methods: From January 2015 to January 2017, there were 181 male patients from Peking University People’s Hospital who were diagnosed clinically with OAB and underwent preoperative urodynamic test. Finally 126 male patients were enrolled in the research. Male OAB patients could be stratified into four groups based on the chief complaints (whether or not presenting urgency) and the results of urodynamic test (whether or not presenting detrusor overactivity and the ability to stop the involuntary contraction). The contents of this follow-up study included the basic information, the preoperative and postoperative scores of the OAB symptom score (OABSS), the preoperative and postoperative scores of the international prostate symptom score (IPSS), and the amount of the concomitant diseases.Results: According to the classification, the amounts of the four types of OAB patients were 32 (25.40%) for type Ⅰ, 27 (21.43%) for type Ⅱ, 59 (46.83%) for type Ⅲ, and 8 (6.35%) for type Ⅳ, respectively. The data of their heights showed no statistical significance (P>0.05). The ages, weights and the amount of the concomitant diseases of type Ⅳ were obviously higher than those of the other three types (P<0.05). And the ages, weights and the amount of the concomitant diseases of the other three types had shown no statistical significance (P>0.05). The improvement of the OABSS and IPSS scores of the type Ⅳ were obviously inferior to the other three types (P<0.05). The improvements of the OABSS and IPSS scores of type Ⅲ were obviously higher than those of the other three (P<0.05). The discrepancy of the OABSS and IPSS scores of type Ⅰ and type Ⅱ had shown no statistical significance (P>0.05).Conclusion: Type Ⅳ has the worst outcome and type Ⅲ has the best among the four types of OAB. And this classification system will certainly have a profound significance in guiding and directing our clinical diagnosis and treatments, and evaluating the prognosis of the patients with OAB.
