A jump rope will flow urine, then the possible causes are: 1. If it is a woman, it is mostly seen in stress incontinence caused by relaxation of the pelvic floor muscles, which can be seen in women who have given birth several times or have had pelvic floor surgery, such as patients after hysterectomy or rectal surgery. It can also be seen in patients with natural relaxation of the pelvic floor muscles as they age, when there is a downward shift and prolapse of the vesicourethra, resulting in a decrease in urethral closure pressure. When increased abdominal pressure is transmitted to the bladder pressure and exceeds the urethral closure pressure, involuntary overflow occurs. A detailed physical examination and urodynamic examination are needed, and after the disease is clearly defined, oral medication, pelvic floor muscle functional exercises are recommended, and severe patients need to be treated with pelvic floor reconstruction surgery.2. In the case of men, it is mostly seen in patients with acute or chronic urinary retention. A large amount of urine filling in the bladder, when jumping rope when the abdominal pressure rises transmitted to the bladder pressure, more than the urethral closure pressure will also appear incontinence, this situation is called filling incontinence, is due to overfilling of the bladder, pressure rise and incontinence. A residual urine ultrasound, male prostate examination or urethroscopy if necessary is required to clarify.
