Serotonergic 5-HT1A receptor agonist (8-OH-DPAT) ameliorates impaired micturition reflexes in a chronic ventral root avulsion model of incomplete cauda equina/conus medullaris injury

► Chronic incomplete cauda equina injury causes poor lower urinary tract function. ► 5-HT1A receptor agonist prolonged the relaxation of urethral sphincter. ► 5-HT1A receptor agonist improves voiding efficiency after cauda equina injury.
