detrusor (plural detrusors or detrusores)

1. (anatomy) A smooth muscle in the wall of the bladder that relaxes to allow urine to be stored and contracts to expel it; often used attributively.
   • 1998, Bonny L. Johnson, Jody Gross, editors, Handbook of Oncology Nursing, 3rd edition, Jones & Bartlett, page 559:

     The brain contains multiple centers that modulate detrusor control. Although the exact mechanism remains unclear, the net effect of the brain's influence on the bladder is to inhibit detrusor contractions until an appropriate time and place for urination.

   • 2004, Nico J. M. Rijkhof, “Chapter 7.4: Emerging FES Applications for Control of the Urinary Bladder”, in Kenneth W. Horch, Gurpreet S. Dhillon, editors, Neuroprosthetics: Theory and Practice, World Scientific, page 1057:

     Detrusor overactivity is defined by the ICS as a urodynamic observation characterised by involuntary detrusor contractions during the filling phase which may be spontaneous or provoked.

   • 2009, Christopher R. Chapple, Scott A. MacDiarmid, Anand Patel, Urodynamics Made Easy, Elsevier (Churchill Livingstone), 3rd Edition, page 88,
