Weakening of Pelvic Floor Muscles and Ligaments
These muscles and ligaments support the urethra and bladder neck. When they weaken, they cannot maintain the urethra and bladder in the correct position, resulting in incontinence.
Pregnancy and Childbirth
Pregnancy and childbirth are major risk factors. During pregnancy, the baby's weight puts pressure on the pelvic floor muscles. Pregnancy, childbirth, and especially vaginal delivery can cause trauma to the muscles and nerves of the area.
Menopause and Hormonal Changes
Menopause often worsens incontinence due to decreased estrogen. This hormonal change affects the elasticity and strength of tissues around the urethra and bladder.
Other Risk Factors
- Obesity: Extra weight increases pressure on the bladder
- Aging: Natural weakening of muscles with age
- Heredity: Family history of incontinence (collagen and tissue quality)
- Chronic cough: From smoking or allergies
Conservative Management
• Kegel exercises are the first line of treatment for mild forms of incontinence. These exercises strengthen the pelvic floor muscles.
• Lifestyle changes such as weight loss that helps reduce pressure on the bladder and smoking cessation which reduces chronic cough
Surgical Treatment
When conservative methods are insufficient, surgical options are considered:
- Urethral Bulking Injections
This is the least invasive method without complications, lasts 5-10 minutes, and success rates exceed 50%
- Tension-Free Tapes (TVT, TVT-O, Autologous Fascial Sling AFS)
This is the most common surgical procedure for stress incontinence. It involves placing a synthetic tape that supports the bladder neck. The success rate of this procedure is approximately 90%.
- Burch Colposuspension
A surgical procedure that lifts and stabilizes the bladder neck. Similar to tapes, the success rate is approximately 90%.
