Abstract

PURPOSE
After correction of stress incontinence, some patients experience the improvement of overactive bladder symptoms. During urodynamic study of some patients, the leak point pressure has a tendency to decrease at increasing vesical volumes. We evaluated the possibility of a correlation between stress incontinence parameters and bladder capacity or compliance.
MATERIALS AND METHODS
113 stress incontinence patients who received urodynamic study from February 2000 to August 2005, were reviewed retrospectively for this study. In these patients, urodynamic stress incontinence parameters(abdominal leak point pressure: ALPP, maximum urethral closure pressure: MUCP), Q-tip angle and Stamey symptom grade and age were analyzed for a correlation with urodynamic cystometric capacity or compliance. We also compared the cystometric capacity of each symptom grade group to assess the difference among the groups. RESULTS: The mean age of the patients was 49.5+/-10.4 years(29~75), symptom grade was I(37), II(27), III(19), Q-tip angle was 33.6+/-14.0 degrees(10~60), cystometric capacity was 390.2+/-109.7 ml(121~641), compliance was 51.6+/-30.4 ml/cmH2O(9.2~142.5), ALPP was 83.2+/-31.0 cmH2O(24~200), MUCP was 55.4+/-29.3 cmH2O(7~142). In the correlation analysis, cystometric capacity had a correlation of -0.207 with age (p=0.029) and -0.215 with symptom grade(p=0.031). However, bladder compliance had no significant correlation with any of the parameters studied. In each symptom grade, cystometric capacity was 407.0+/-103.1 cc(I), 395.8+/-103.0 cc(II), 324.5+/-124.0 cc(III)(p=0.04) and the age for each symptom grade was 48.5+/-9.7(I), 48.1+/-10.1 (II), 57.3+/-10.1(III)(p=0.005). CONCLUSION: As cystometric capacity decreased, symptom grade of stress incontinence increased and age also increased. However, there were no other correlations between cystometric capacity or compliance and stress incontinence parameters.
