Low amplitude rhythmic contraction frequency in human detrusor strips correlates with phasic intravesical pressure waves

Purpose Low amplitude rhythmic contractions (LARC) occur in detrusor smooth muscle and may play a role in storage disorders such as overactive bladder and detrusor overactivity. The purpose of this study was to determine whether LARC frequencies identified in vitro from strips of human urinary bladder tissue correlate with in vivo LARC frequencies, visualized as phasic intravesical pressure (p ves) waves during urodynamics (UD).
