Abstract: Objective To explore the application and effect of Buzhong Yiqi Decoction in the treatment of dysuria after prostatectomy in patients with clinical benign prostatic hyperplasia （BPH）. Methods A digital randomization method was used to divide the 108 patients into two groups, with BPH who were unable to urinate after treatment with electrosurgical prostatectomy in Rizhao Hospital of Traditional Chinese Medicine from October 2019 to September 2021. Each group included 54 patients. They were given routine treatment and Buzhong Yiqi treatment respectively. The treatment effects of the two groups were compared and analyzed. Results After corresponding treatment, the total effective rate of treatment in group A was significantly lower than the group B’s. There was a significant difference between the two groups （P<0.05）. Before treatment, the maximum urine flow (Qmax) of the two groups was comparative, and the analysis of Residual Urinary Volume of Bladder (RUV) and International Prostate Symptoms (IPSS) scores and quality of life showed no significant difference （P>0.05）. After treatment, the Qmax and quality of life scores of group B were both significant higher than that of group A, while the scores of RUV and IPSS were significantly lower than that of group A （P<0.05）. Conclusion According to the situation of BPH patients with weak micturition after prostatectomy, the application of Buzhong Yiqi Decoction can significantly improve the urodynamics of patients, the symptoms of weak micturition, and the quality of life of patients. The overall effect is remarkable, which is worthy of application in clinic.
