Objective. To assess the quality of life and sexual function in women with symptomatic cystocele. Patients and methods. A prospective cross-sectional controlled study was conducted. It included 105 women: 70 patients with isolated symptomatic cystocele (N81.1) stage II-III according to the POP-Q classification and 35 women without signs of pelvic organ prolapse. All patients were matched for age and parity. The mean age of participants was 45.9 ± 8.0 years. Quality of life was assessed using validated questionnaires: PFDI-20 (Pelvic Floor Distress Inventory), P-QOL (Prolapse Quality of Life Questionnaire), PISQ-12 (Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire). Results. Patients with cystocele showed statistically significant pelvic floor dysfunction: total PFDI-20 score was 142.8 ± 52.4 vs. 18.6 ± 12.3 in the control group (p < 0.001, Cohen’s d = 2.86). The most severe disorders were noted in the domains of urinary symptoms (58.7 ± 24.1 vs. 6.2 ± 8.4, p < 0.001) and prolapse symptoms (52.7 ± 19.6 vs. 7.3 ± 6.8, p < 0.001). Cystocele had a systemic negative impact on all aspects of quality of life (P-QOL): the largest effect size was found in the “prolapse impact” domain (Cohen’s d = 4.35). The analysis of sexual function in women with cystocele demonstrated a significant negative impact on all aspects of sexual function (total PISQ-12 score 31.8 ± 6.2 vs. 37.4 ± 4.9, p < 0.001). Strong correlations were found between the anatomical degree of prolapse and specific perineological symptoms (r = 0.608–0.623). Multifactorial analysis showed that prolapse stage is the only independent predictor of deterioration in quality of life (β = 42.3, p < 0.001). Conclusion. Isolated symptomatic cystocele has a significant negative impact on women’s quality of life, affecting physical, psychological, social aspects of well-being, and sexual function. The anatomical degree of cystocele is the main predictor of functional disorder severity. © 2025 Elsevier B.V., All rights reserved.
