OBJECTIVES: To introduce a new, simple, non-invasive test to quantify urethral hypermobility.
METHODS: We reviewed data of women with urinary incontinence who were examined at the Department for General Gynaecology and Urogynaecology, Clinic for Gynaecology and Perinatology, Maribor, Slovenia, between October 2010 and March 2014. Patients' age, diagnosis, results of the Q-tip test and Pelvic Organ Prolapse Quantification measurements were collected. In addition, a new parameter was defined as anterior compartment descent, a midline distance between the external urethral meatus and maximum descent of the anterior vaginal wall when performed the Valsalva maneuver. Statistical analysis was performed with spss software using the Mann-Whitney test, correlation, regression and receiver operating characteristic curve analysis. The analysis was also carried out separately for patients with anterior compartment prolapse stage 0 or I.
RESULTS: A total of 472 women were included, 323 of them with anterior compartment prolapse stage 0 or I. Women with urethral hypermobility had significantly higher anterior compartment descent values than patients without urethral hypermobility (3.7 cm vs 2.6 cm, P < 0.001). A moderate correlation was found between anterior compartment descent and the Q-tip test (Spearman's rho = 0.55, P < 0.001). Age and anterior compartment descent were identified as independent variables for the presence of urethral hypermobility. When the cut-off value is set at 3.5 cm, anterior compartment descent represents a test for urethral hypermobility assessment with sensitivity of 65.2%, specificity of 88.6%, positive predictive value of 97.0% and negative predictive value of 30.7%. Anterior compartment descent values were also significantly higher in patients with anterior compartment prolapse stage 0 or I (3.4 ± 0.7 cm vs 2.6 ± 0.7 cm, P < 0.001).
CONCLUSIONS: The anterior compartment descent could be a valuable tool for the assessment of urethral hypermobility. Further effort should be directed into the standardization of the technique, determination of the normal range of anterior compartment descent, and its intra- and interobserver reliability.
