Abstract

PURPOSE
To evaluate the relationship between urethral hypermobility and Valsalva leak point pressure (VLPP), subjective symptom degree in women with stress urinary incontinence.
MATERIALS AND METHODS
229 patients who were diagnosed as stress urinary incontinence and had undergone all of standing cystourethrogaphy, urodynamic study including VLPP, and recording questionnaire of incontinence were included in this study. The subjective degree of stress urinary incontinence was graded to 3 grades by Stamey classification, and urethral mobility more than 2.0 cm on standing cystourethrography was determined as the urethral hypermobility. And patients were stratified 3 groups according to the VLPP of less than 60, 60 to 90 and greater than 90 cmH2O. Correlation between urethral hypermobility and VLPP, subjective symptom degree were evaluated.
RESULTS
According to the VLPP of less than 60, 60 to 90 and greater than 90 cmH2O, urethral hypermobility was noted in 49.4%, 86.6%, 92.4%, respectively. The rate of urethral hypermobility increased according to VLPP does with statistical significance (p<0.05). And in subjective symptom grade I, II, III urethral hypermobility was noted in 75.0%, 79.7%, 61.0%, respectively. There was not significant correlation between urethral hypermobility and subjective symptom degree (p=0.15).
CONCLUSION
Our results suggest that there is significant correlation between urethral hypermobility and VLPP. And in some of patients with stress urinary incontinence urethral hypermobility and intrinsic sphincter deficiency are coexist. However, we suggest that the preoperative evaluation for urethral hypermobility and intrinsic sphincter deficiency is needed to assess the surgical outcome more exactly in the patients with stress urinary incontinence.
