Laparoscopic radical prostatectomy (LRP) is the main treatment method for early prostate cancer, and postoperative urinary incontinence is one of the main complications after LRP. Urologists have applied various new operations in clinical practice to improve the urinary incontinence of patients after LRP surgery, but urinary incontinence is still the main problem affecting the quality of life of patients after surgery. In recent years, we have found that the new bladder neck urethral reconstruction method adopted by our department in LRP surgery can effectively improve the postoperative urinary incontinence of patients. In this study, a randomized controlled trial was intended to verify that the new bladder and neck urethral reconstruction technique could effectively improve early urinary control in patients after radical laparoscopic prostatectomy, and the patients were randomly divided into four groups by factorial design: posterior reconstruction group, posterior reconstruction +anterior suspension group, Sham group, and anterior suspension group to further verify the influencing factors of improved urinary control. The aim is to prove that the new operation can effectively reduce the urinary incontinence rate of patients after LRP, and analyze the mechanism of the new operation to improve the urinary incontinence of patients after LRP, and provide a new idea for the reconstruction of bladder neck and urethra during laparoscopic radical prostatectomy.
