Defining urge as an uncontrolled micturition explains pathogenesis, informs cure and helps solve the burgeoning OAB crisis.

ABSTRACT:

Background

Parallel with the demographic ageing crisis, is a disabling overactive bladder (OAB) crisis (urgency/frequency/nocturia), 30% prevalence in older women, pathogenesis stated as unknown and, according to some learned societies, incurable.

Hypothesis/aims

To review International Continence Society and Integral System paradigms to test our thesis that OAB per se is not a pathological condition, rather, a prematurely activated uncontrolled micturition; pathogenesis being anatomical damage in a nonlinear feedback control system comprising cortical and peripheral (muscle/ligament) components.

Methods

We examined studies from basic science, anatomy, urodynamics, ultrasonic and video xrays, ligament repairs, from which we created a nonlinear binary model of bladder function. We applied a Chaos Theory feedback equation, X_next = Xc(1 - X) to test our hypothesis against existing concepts and hypotheses for OAB pathogenesis.

Results

The bladder has ONLY two modes, EITHER closed OR open (micturition). Closure is reflexly controlled cortically and peripherally: muscles contracting against ligaments stretch the vagina to suppress afferent signals to micturate from urothelial stretch receptors. "OAB" can be caused by anatomical damage anywhere in the model, by childbirth or age-weakened ligaments, which can be repaired to cure all three OAB symptoms. Urodynamic "DO" graphs are interpreted anatomically and by the feedback equation.

Conclusion

OAB is in crisis. Our thesis of OAB as an uncontrolled micturition from anatomical defects in the bladder control system provides fresh directions for further development of new treatments, nonsurgical and surgical, to help break the crisis and bring hope and cure to 600 million women sufferers.

Project description:What is this summary about? This is a plain language summary of an article published in the journal Advances in Therapy. In 2020, the US Food and Drug Administration (also called the FDA) approved a medicine called vibegron to treat overactive bladder, also called OAB. The key results used to approve vibegron were from the EMPOWUR study. In the EMPOWUR study, participants who took vibegron had fewer urination episodes, urgency episodes, and bladder leaks each day than those who took a pill containing no medicine, called a placebo. At the end of the study, participants also rated how much their overactive bladder symptoms changed overall during EMPOWUR by responding to a survey. Many participants rated their overactive bladder symptoms as improved overall. This study asked if improvements in the number of urination episodes, urgency episodes, and bladder leaks caused by urgency were associated with feeling better overall. This study also looked at how many participants in the EMPOWUR study had improvements in the number of urination episodes, urgency episodes, and bladder leaks that were big enough to matter. A separate group of people with overactive bladder were asked about the magnitude of improvements that would be important to them. This group had not participated in the EMPOWUR study. What were the results? EMPOWUR participants who reported that taking medicine resulted in their overactive bladder symptoms getting better overall also generally reported fewer daily urinations, urgency episodes, and bladder leaks after treatment. Many had changes in their symptoms that were meaningful. Meaningful was defined for each symptom as: at least 15% fewer urinations, 50% fewer urgency episodes, and 75% fewer bladder leaks. Participants who received vibegron had meaningful reductions in the daily number of episodes of urination, urgency, and bladder leaks more often than those who received the placebo (pill with no active medicine). People with overactive bladder who did not participate in the study were interviewed and said that improvements to those symptoms, similar to those seen in the EMPOWUR study, would be important to them. What do the results mean? This study suggests that the results we measured in the EMPOWUR study may also reflect changes in overactive bladder symptoms that are big enough to be important to people with overactive bladder. Many participants who took vibegron in the EMPOWUR study felt that it helped to improve their individual overactive bladder symptoms. This may also help improve quality of life of participants.
