Urinary incontinence after hysterectomy may be related to the decreased supportive capacity of the pelvic floor muscles, damage to the bladder and ureter, and removal of the pelvic floor muscle nerves. 1. Decrease in the supporting ability of the pelvic floor muscle: it may be related to the decrease in the number of organs in the pelvic cavity after hysterectomy, and the absence of supporting tissues around the urethra, which leads to a decrease in the supporting ability of the pelvic floor muscle tissues for the urethra, and may cause the urethra to move downward, and the phenomenon of stress incontinence occurs. 2. The bladder and ureter are damaged: the bladder and uterus are relatively close to each other in the pelvis. During hysterectomy, it is likely to damage the bladder and ureteral nerves, affecting the urinary system and leading to urinary incontinence. 3. Resection of the pelvic floor muscle nerves: during hysterectomy, due to the large lesion site and the needs of the condition, the pelvic floor muscle nerves may be damaged or removed during the operation, which may easily lead to the loss of sensation in the urinary system and the emergence of urinary incontinence. When urinary incontinence after hysterectomy occurs, it is recommended to consult a doctor for examination in time, and choose a reasonable treatment plan under the doctor’s comprehensive analysis.
