Project Title: Spontaneous contractions in the bladder muscle and the irritable bladder syndrome

Urgency of micturition( a sense of urgent desire to urinate) is a significant medical problem particularly in older people . The condition is thought to result from an unstable pattern of muscle contraction in the bladder. Whilst little is known about the manner in which the bladder muscle acts to expand its volume to accommodate incoming urine, it is thought that faults in this system cause the pressure to rise and the sense of urgency to develop. Scientists at Massey in Cooperation with a senior consultant Urologist at Palmerston North Hospital are using state of the art imaging techniques to gain an understanding of this process. A technique developed by an engineer and a physiologist called two dimensional spatiotemporal mapping can detect movements of the bladder wall by comparing the movements of irregularities on its surface in successive video frames . The group have just finished an initial trail which showed that these movements occur in patches in a rhythmic alternating manner so that portions of the bladder wall rest whilst others are actively contracting. Further, that the contracting patches seem to occur more frequently near the bottom of the bladder and to migrate outwards and upwards. The next step in the development is to film the bladder wall of people who have urgency of micturition to see if this organisation of contractions has changed. If so then this will allow the technique to be used to evaluate whether and drugs or other procedures can restore the disturbed pattern back to to normal.
