Possible causes of involuntary urine loss when coughing: First, stress incontinence, which is common in women, especially those who have given birth vaginally several times, or those who suffer from uterine prolapse and pelvic floor muscle relaxation. Because the pelvic floor muscle relaxation after the urethra shifts down, at this time the urethral sphincter pressure decreases and leads to incontinence when the patient uses abdominal pressure, such as coughing, loud talking, laughing, sneezing, etc., can appear urine involuntarily by the urethral orifice outflow. This condition is a functional disease, and if the symptoms are mild, it can be treated with oral medication. But if the symptoms are more serious, affecting life and social life, you can perform surgical treatment and do urethral suspension surgery, which can completely solve this kind of disease. Second, the recovery period after various urethral surgeries, such as male prostatic hyperplasia, after performing prostatectomy, a short-term incontinence state may occur when coughing or talking loudly, which may be related to the incomplete closure of the sphincter after surgery. Regular observation is recommended, and it usually relieves itself or disappears after 2 weeks to 3 months.
