LATITUDE An Observational Study of Patient Choice and the Urethral Bulking Agent Bulkamid


Brief description of study

Latitude is an observational study exploring how effective Bulkamid is as a first line treatment for women with stress urinary incontinence. Women who choose to have Bulkamid as part of their standard clinical care will be asked to complete questionnaires before and after their surgery so that we can assess how their urinary symptoms change.

As a second part of the study, we are asking all patients having any first line treatment for stress incontinence to complete a short questionnaire telling us how they decided what treatment to have. A small number of these women will be contacted via telephone and asked whether they would mind being interviewed to tell us more about this.

We will also interview a number of doctors taking part in Latitude to find out how they counsel patients about different treatment options for stress urinary incontinence.

Detailed Study Description

This is a multi-centre observational study to investigate the effectiveness of the urethral bulking agent, Bulkamid, as a primary treatment for stress urinary incontinence (SUI). It also contains an embedded qualitative sub-study to investigate factors that influence patient choice of surgical treatment for SUI.

Bulkamid is a non-toxic hydrogel that is injected under the lining of the urethra. It increases the urethral 'bulk', hence increasing resistance against leakage of urine. It is being increasingly offered as a primary treatment for SUI due to the reduced associated risks, ability to administer in the outpatient setting and recent controversy surrounding polypropylene mesh. However, there is currently limited data on how effective it is as a first line treatment, both in the short and long term, and what effect it may have on secondary continence procedures.

This study aims to collect data from 220 women who choose Bulkamid as their primary treatment over a total of 60 months to review its effectiveness. Telephone consultations will take place at regular intervals using validated questionnaires to assess SUI symptoms.

It is not known how easy women find it to choose between the surgical treatment options for SUI, what factors they weigh up or what information would help them make this decision. The embedded qualitative study of patient choice will use a combination of questionnaire and 2 in-depth semi structured interviews to investigate this further. Consultant Urogynaecologists will also be interviewed to compare factors they think are important to their patients' treatment decision with what is expressed by women with SUI. The overall aim is to develop a prototype decision aid to better support women when making this treatment decision.
