Apparatus for calibration of a uroflowmeter.
A device has been constructed in order to obtain a flow analogous with the flow during micturition. Sources of error with instruments used in connection with micturition analysis can be determined by using this apparatus.
Urinary flow and flow pattern in paraplegics
This paper deals with uroflowmetry in 34 paraplegics with neurogenic bladder dysfunction.
Micturition cinematography with simultaneous pressure-flow study in infancy and childhood.
Summary A new method of micturition cinematography and simultaneous pressure-flow recordings make it possible, with 1/16 second accuracy, to correlate the radiological picture of micturition obtained in A-P and lateral projections with the intravesical pressure and urine flow. Fifteen to twenty per cent of female children with recurrent urinary tract infection have a rather remarkable dilatation of the bladder neck and urethra, apparently caused by a dysfunction of the primary urinary sphincter and external sphincter. The latter dilates insufficiently possibly because of inflammation and fibrosis.
