Correlation between the female pelvic floor biomechanical parameters and the severity of stress urinary incontinence

Table 2 Examination of bivariate associations between selected VTI parameters and MESA SUI index, MESA SUI score

VTI parameter				MESA SUI Index	MESA SUI Score
No.	Description	Interpretation		MESA SUI Index	MESA SUI Score
4	The maximum value of posterior gradient (change of pressure per posterior wall displacement in the orthogonal direction to the vaginal channel)	The maximum value of tissue elasticity in the posterior compartment behind the vaginal at a specified location	r	0.373	0.376
4			P	0.039	0.037
27	Displacement of the maximum pressure peak in the anterior compartment	Mobility of anterior structures Valsalva maneuver	r	0.366	0.363
27		Mobility of anterior structures Valsalva maneuver	P	0.043	0.044

Simple correlation analyses were used, and Pearson Correlation Coefficient (r) was calculated. Pearson correlation coefficient ‘r’ corresponds to the direction of the relationship. Probability values (P) less than 0.05 were considered significantly different. Only those parameters are shown for which a significant correlation could be found (P < 0,05)
