Abstract: This study explored the changes of pelvic floor ultrasound parameters and urodynamic parameters before and after total hysterectomy in patients with cervical cancer and the effect of pelvic floor rehabilitation. 137 cases of cervical cancer patients undergoing total hysterectomy were selected for clinical research. All patients were tested for pelvic floor ultrasound parameters and urodynamic parameters before and 3 months after surgery, among them, 120 patients received pelvic floor rehabilitation after surgery. The results showed: the measured value of the bladder neck reduction, the urethral rotation angle, the posterior angle of the bladder neck in the resting state, the posterior angle of the bladder and the urethra in the maximum Valsalva state, and the vertical distance between the bladder neck and the underside of the pubic symphysis (BSD) all increased to a certain extent compared with those before the operation (P<0.05). After the operation, the patient’s bladder compliance, maximum urine flow rate, and maximum detrusor pressure were significantly lower than those before the operation (P<0.05), and the maximum bladder volume was significantly increased (P<0.05). Total hysterectomy will have obvious adverse effects on the pelvic floor function and bladder voiding function for patients with cervical cancer. This part of patients should be given appropriate rehabilitation after the operation to promote the recovery of function and improve the quality of life.
