Voiding dysfunction is a common disease that contributes to a lower quality of life and has an increased prevalence in the elderly population. Noninvasive and objective methods such as uroflowmetry (UFM) and voiding diaries (VDs) are essential for exact diagnosis and effective treatment of this condition because patients with different causes of voiding dysfunction can complain of the same lower urinary tract symptoms. Further, different treatment options can be determined based on the diagnosis made from these symptoms...

REVIEW
Karl Erik Andersson
The clinical success of mirabegron as the first β3-adrenoceptor (AR) agonist for treatment of the overactive bladder (OAB) syndrome, has resulted in substantial interest in its site and mechanism of action. Even if the adrenergic innervation of the bladder and urethra has been well studied, the location(s) of β3-ARs in different structures within the bladder wall and urethra, and the mode(s) of action of β3-AR stimulation have still not been established. The recent demonstration of β3-ARs on cholinergic nerve terminals with no immunoreactivity in urothelium or detrusor smooth muscle, is not in agreement with previous morphological studies, and functional data strongly suggest that β3-ARs can be found these structures...

PURPOSE: The aim of this study was to assess the potential involvement of a specific subtype of 5-hydroxytryptamine (5-HT), 5HT2 receptors in neurally-induced contractions of the human detrusor. METHODS: Contractile responses to electrical field stimulation (EFS) were examined in human isolated urinary bladder muscle strips. The potentiation of EFS-induced detrusor contraction was examined by adding cumulative concentrations of a 5-HT and 5-HT2 receptor agonist, α-methyl-serotonin (α-Me-5-HT) (1nM-100μM) in the presence or absence of a 5-HT2 antagonist, ketanserin (5-HT2A>5-HT2C) or naftopidil (5-HT2B>5-HT2A) (0...
