Aims: To determine surgeons' views on invasive urodynamic testing (IUT) prior to surgery for stress (SUI) or stress predominant mixed urinary incontinence (MUI). Methods: Members of British Society of Urogynaecology (BSUG) and British Association of Urological Surgeons Section of Female, Neurological and Urodynamic Urology (BAUS-SFNUU) were sent an email invitation to complete an online “SurveyMonkey®” questionnaire regarding their current use of IUT prior to surgical treatment of SUI, their view about the necessity for IUT in various clinical scenarios, and their willingness to randomize patients into a future trial of IUT. A purposive sample of respondents was invited for telephone interview to explore further how they use IUT to inform clinical decisions, and to contextualize questionnaire responses. Results: There were 176/517 (34%) responses, 106/332 (32%) from gynecologists/urogynecologists and 67/185 (36%) from urologists; all respondents had access to IUT, and 89% currently arrange IUT for most women with SUI or stress predominant MUI. For a variety of scenarios with increasingly complex symptoms the level of individual equipoise (“undecided” about IUT) was very low (1–6%) and community equipoise was, at best, 66:34 (IUT “essential” vs. “unnecessary”) even for the simplest scenario. Nevertheless, 70% rated the research question underlying the proposed studies “very important” or “extremely important;” 60% recorded a “willingness to randomize” score ≥8/10. Conclusions: Most urogynecologists and urologists consider IUT essential before surgery in SUI with or without other symptoms. Most however recognize the need for further research, and indicated a willingness to recruit into multicenter trials addressing this question.
