The effect of two widely used cyclooxygenase inhibitors (indomethacin and ketoprofen) on the low filling rate cystometrogram was investigated in urethane anesthetized rats. Both indomethacin and ketoprofen significantly increased volume threshold to elicit neurogenic bladder contractions without affecting their amplitude. Also the pressure threshold was unaffected by both drugs while the volume/pressure relationship was significantly flattened compared to controls. These findings indicate that acute suppression of arachidonic acid metabolism along the cyclooxygenase pathway increases the micturition threshold without affecting bladder muscle contractility and/or neurotransmission along the efferent pathway of the micturition reflex.
