Abbreviations: BMI, body mass index; IQR, interquartile range; ISD, intrinsic sphincter deficiency; OABq, Overactive Bladder Questionnaire, Short Form; OABq, HRQL, health-related quality-of-life component of the bother component of the Overactive Bladder Questionnaire, Short Form; SCH, supracervical hysterectomy; TAH, total abdominal hysterectomy.
Values are presented as number and percentage of patients unless specified otherwise.
Race was based on patient self-report.
The OABq symptom severity, ranges from 0 to 100, with higher scores representing greater symptom severity or bother.
The OABq, HRQL scores range from 0 to 100, with higher scores representing better health-related quality of life.
ISD was defined as an abdominal leak point pressure <60 cm H2O or a maximum urethral closure pressure <20 cm H2O.
Detrusor contracting during the cystometry phase of the urodynamics examination. Results are based on those patients with complex urodynamics only.
Please see Appendix 1 for definition.
