  • CONCLUSIONS: The results indicate that, in female rats anaesthetized with urethane, the nNOS inhibitor administrated through the intrathecal route inhibits urethral sphincter relaxation, while intracerebroventricular injection increases the sphincter tonus, without changing bladder function. These changes were reverted by L-Arginine administration. These findings suggest that the urethral sphincter and detrusor muscle function is modulated by nitric oxide.
  • Application of shear wave elastography to estimate the stiffness of the male striated urethral sphincter during voluntary contractions. [Journal Article]
  • BIBJU Int 2016 Oct 18
  • Stafford RE, Aljuraifani R, … Hodges PW
  • CONCLUSIONS: Voluntary contraction of the pelvic floor muscles in men is associated with an area of stiffness increase measured with shear wave elastography, which concurs with the expected location of the striated urethral sphincter. The increase in stiffness occurred in association with an increase in perineal surface EMG activity, providing evidence that stiffness amplitude relates to general pelvic floor muscle contraction intensity. Future applications of shear wave elastography may include investigations of patient populations in which dysfunction of the striated urethral sphincter is thought to play an important role, or investigation of the effect of rehabilitation programmes that target this muscle.

  • Urologic symptoms and functional neurologic disorders. [Journal Article]
  • HCHandb Clin Neurol 2017; 139:469-481
  • Hoeritzauer I, Phé V, Panicker JN
  • The term functional urologic disorders covers a wide range of conditions related broadly to altered function rather than structure of the lower urinary tract, mainly of impaired urine voiding or stor...
