Urethral Bulking Agents
Urethral bulking agents have a long medical history outside of urology in areas such as aesthetic dermatology, gastroesophageal reflux, as well as for patients with glottis insufficiency. Since urethral bulking agents (UBA) were first introduced, many have come and gone and it is clear from the literature that not one has, as yet, lived up to the expectations and requirements of an ideal UBA. As a result, their place within the treatment armament for women suffering from stress urinary incontinence (SUI), is largely relegated to a last resort treatment. However, in recent years UBA treatment for female urinary incontinence has become increasingly popular due to the minimally invasive nature and improvement in performance, also leading to a demand for a new type of urethral injectable product with additional beneficial characteristics.
