3.4 TOT increases voiding resistance
For TOT is well-recognized to increase the resistance of the urethra during urine storage,23 we examined if TOT also affects outlet resistance during urine voiding by assaying if TOT affect the mean urethra resistance (Rv).
As anticipated, TOT increased individual Rv in most patients (21 out of 26, 80%; Figure 4A) as well as significantly increased the mean value of Rv of patients when compared with the pre-operative control, indicating TOT did increase the outlet resistance during voiding.
