Abstract

PURPOSE
We evaluated the correlation of Valsalva leak point pressure, maximum urethral closure pressure, and urethral hypermobility in the diagnosis of genuine stress incontinence.
MATERIALS AND METHODS
From January 1997 to January 1999, one hundred thirteen patients with genuine stress incontinence had undergone three measures determined in a standardized fashion. We compared three parameters with symptom grades of genuine stress incontinence.
RESULTS
Of the total 113 patients, genuine stress incontinence were grade I in 39, II in 43 and III in 31. There were significant difference in the incidence between grade III and grade I or II in Valsalva leak point pressure, maximum urethral closure pressure, and urethral hypermobility(p<0.05). Valsalva leak point pressure was the most significnat correlation with symptom grade(r=0.4), but there were not correlation among Valsalva leak point pressure, maximum urethral closure pressure, and urethral hypermobility in grade III geniune stress incontinence patients and 66.7% of grade III genuine stress incontinence patients had urethral hypermobility.
CONCLUSIONS
With these results, Valsalva leak point pressure is good indicator for intrinsic sphincter deficiency. But intrinsic sphincter deficiency should be diagnosed by composites of historic, urodynamic, anatomic, and other clinical factors.
