The measurement of urinary How rate is clearly the most important objective screening test for evaluations of normal or abnormal urodynamics in the lower urinary tract. The various types of flowmeters have been reported for this purpose. We have used mictiometer 14-F-40 in DISA urological investigation system which has been tested for its accuracy, In this study 177 normal urinary How curves in 8 adult males were statistically analysed using 10 parameters in the urinary How curves. The results obtained were as follows; 1. Maximum How rate (MFR) increased propotionally with volumes below 200 ml (r=0.8623, p<0.01), so that it is difficult to determine the normal range of MFR in these volumes. Therefore calculation of voided volume/MFR (caluculated minimal time of micturition) were enhanced. This normal range was calculated as less than 10 seconds. MFR were almost constant with volumes over 200 ml (27.7±3.8 ml/sec, mean±s.d.).
