Comparison Of Ambulatory And Conventional Urodynamics In Females With Stress Urinary Incontinence

ObjectiveTo compare the application of ambulatory urodynamic (AUM) and conventional urodynamic (CUD) in detecting stress incontinence (SUI) and the detrusor overactivity in females.MethodsIncontinence questionnaire short form (ICI-Q-SF), CUD and AUM were administrated in30female patients,the age was32～63(49.4±9.449) years old, and duration of symptom was1～9(4.7±2.784) years. Patients were divided into3groups of mild (n=9), moderate (n=15) and severe (n=6) according to ICI-Q-SF. Three micturition cycles were recorded during AUM.ResultsSUI and detrusor overactivity (DO) detected by AUM were90%and37%, significantly more than those by CUD70%and10%(p<0.05). Twenty-one moderate and severe SUI patients diagnosed by ICI-Q-SF, detected by AUM and CUD simultaneously showed that abdominal leak point pressure(ALPP) and voided volume were lower, and detrusor pressure was higher recorded by AUM than those by CUD significantly (p<0.05).ConclusionOur findings suggested that SUI and DO detected by AUM were easier than those by CUD. The reason for this may be related to the lower ALPP exited during the AUM. Moreover, in the absence of AUM, many patients would have been misdiagnosed on their CUD results. AUM was an useful additional tool in clinical urological practice for those patients where CUD had failed to explain their symptoms.
