Abstract

Objectives. To determine whether knowledge about previous surgical history for incontinence and responses to a validated lower urinary tract symptom questionnaire for women could identify those who should undergo urodynamic testing before surgery for stress urinary incontinence (SUI). Methods. A retrospective analysis of all women who completed the Urogenital Distress Inventory-6 questionnaire (UDI-6) and then underwent complete urodynamic studies was conducted. The critical urodynamic diagnoses to determine before anti-incontinence surgery were defined as coexisting SUI and detrusor instability (DI), Valsalva leak point pressure less than 60 cm H2O, and DI alone in women suspected clinically of having SUI. Models were established for deciding who should undergo urodynamic studies on the basis of questionnaire responses and information about previous surgical history. Cost savings and the ability of the various models to identify patients with critical urodynamic diagnoses were calculated. Results. A total of 174 women completed the UDI-6 and underwent urodynamics studies. Sixty-two had SUI (36%), 54 had DI (31%), 18 had both SUI and DI (10%), and 19 women suspected of having SUI were found instead to have DI (11%). Among women with SUI, 39 had a Valsalva leak point pressure less than 60 cm H2O (63%). No group of question responses or combination of question responses and presence of previous incontinence surgery was able to identify all three critical urodynamic diagnoses with statistical significance. Still, the combination of a response of '2' or '3' to question 3 on the UDI-6 and a positive history of previous surgery would have identified 91% of the critical diagnoses, and a substantial cost savings would have been realized. Conclusions. Using the UDI-6 and information obtained from the patient's history to determine who should undergo urodynamic testing before surgery for SUI can result in substantial cost savings without sacrificing patient care.
