Preoperative Evaluation of Posterior Deep-Infiltrating Endometriosis Demonstrates a Relationship with Urinary Dysfunction and Parametrial Involvement

Abstract Study Objective To estimate the association between urinary symptoms and quality of life in patients with posterior deep-infiltrating endometriosis (DIE) with anatomical locations of endometriosis. Design Prospective nonrandomized study (Canadian Task Force classification II-2). Setting Tertiary care hospital. Patients One hundred fifty-three patients with DIE and 28 control subjects. Interventions Clinical examination completed using transvaginal ultrasonography and magnetic resonance imaging. Measurements and Main Results Urinary symptoms and quality of life were evaluated using the International Prostate Symptom Score (IPSS) and Bristol Female Lower Urinary Tract Symptoms (BFLUTS) questionnaires. There was a higher incidence of urinary symptoms and a high IPSS in patients with posterior DIE compared with the control group. The IPSS questionnaire detected a relation between parametrial endometriosis and voiding symptoms (p = .03), altered quality of life (p = .02), and a high total score (p = 0.04) in patients with posterior DIE. No difference in urinary symptoms and total BFLUTS score was observed between the groups. A relation was found between parametrial endometriosis and urinary symptoms (p = .02), altered quality of life (p = .04), and high total score (p = .03) in patients with posterior DIE. At multivariable analysis, a correlation was found between parametrial endometriosis and IPSS total score (p = .03), IPSS voiding symptoms (p = .04), and IPSS quality of life (p = .009). Similarly, a correlation was found between parametrial endometriosis and BFLUTS symptoms (p = .003), BFLUTS quality of life (p = .003), and BFLUTS total score (p = .007). Conclusion Patients with posterior DIE have a high incidence of urinary symptoms. Moreover, parametrial endometriosis is associated with altered urinary function and should be systematically evaluated in these patients.
