Cystocele is the most common type of genital prolapse because it involves the anterior vaginal wall, where the bladder descends into the vagina due to weakening of the pubocervical fascia. This type of prolapse is frequently seen in women with childbirth trauma, chronic straining, or pelvic floor muscle weakness. Surgically, repair focuses on reinforcing the pubocervical fascia and performing an anterior colporrhaphy to restore support. This approach addresses the primary defect and reduces symptom recurrence, making it the cornerstone of surgical management for cystocele.
