  • Title: [New findings on the mechanism of micturation].
    Author: Magasi P.
    Journal: Acta Chir Acad Sci Hung; 1977; 18(3):231-4. PubMed ID: 605719.
    Abstract:
    The nervous and muscular events in the start and process of micturation are analyzed. The experiments have shown that in the start of voluntary micturation the close anatomical link between the perineal cross-striated musculature and the neck of the bladder plays an important role. The fact that the straining of the vesicular musculature leads to the contraction of the detrusor is attributed a major importance in the maintenance of the process of urination. The thrusting force of the vesicular musculature transports the urine into the neck of the bladder where the pressure rises and the muscles of the bladder wall become stressed. The arising stimulation enhances the contraction of the detrusor and this process prevails up to the end of micturation. The experiments support the clinical findings, since they explain the different behaviour of central and partial cystoparalysis, thus the almost normal functioning of the reflex bladder and the atony of the "non-reflex" bladder.
