ABSTRACT
PURPOSE:
The aim of the study was to evaluate the relationship between Valsalva leak-point pressure (VLPP) and cough leak-point pressure (CLPP) in the patients with stress incontinence and to determine the correlation between maximal urethral closure pressure(MUCP) and leak point pressure. MATERIALS ANDMETHODS:
Thirty women with stress urinary incontinence were included. Two women were excluded from the evaluation because of detrusor instability. At the bladder volume of 200-300ml cough leak-point pressure and Valsalva leak-point pressure were measured in the sitting position by using 8Fr intravesical catheter.RESULTS:
Valsalva leak-point pressure was significantly lower than cough leak-point pressure (69.4+/-24.5 versus 86.6+/-28.1cmH2O, p<0.0001). If intrinsic sphincter deficiency was defined as a leak-point pressure of 60cmH2O or less, 21.4% of women fulfilled this criterion using the cough leak-point pressure compared to 42.8% if the Valsalva leak-point pressure is used. Valsalva leak-point pressure and maximal urethral closure pressure were statistically correlated (p<0.05). However, a correlation coefficient of 0.38 demonstrated poor clinical relationship.CONCLUSION:
Cough leak-point pressures were significantly higher than Valsalva leak-point pressures. Cough and Valsalva maneuvers seem to result in a different reaction of the pelvic floor. Valsalva leak-point pressure has more statistical correlation to the maximal urethral closure pressure than cough leak-point pressure. So Valsalva leak-point pressure may have a additional benefit for detecting type III stress urinary incontinence. However, variations in Valsalva leak-point pressure measurement must be precisely descibed, standardized, and validated before a technique can be advocated for clinical use.
