Correct option is A
Cystocele is the herniation of the bladder into the vaginal wall due to pelvic floor weakness. It often causes stress urinary incontinence, where urine leaks during coughing, laughing, or sneezing. Explanation of each option: • (a) Cystocele – Correct. It is the most common cause of stress incontinence. The bladder bulges and exerts pressure on the urethra, leading to urine leakage during exertion. • (b) Rectocele – Posterior vaginal wall herniation of the rectum; usually presents with constipation or difficulty with bowel evacuation, not urinary symptoms. • (c) Enterocele – Involves small intestine herniation through the vaginal wall; causes pelvic pressure or bulge but not incontinence. • (d) Urethrocele – Prolapse of the urethra; less commonly associated with stress incontinence compared to cystocele.
