Compared to baseline what was the result of onabotulinumtoxinA (100 U)  on voided volume?
Nevertheless, significant improvements in videourodynamic parameters including detrusor pressure (from 40.3 ± 23.0 to 31.6 ± 22.3 cmH2O), maximum flow rate (from 6.4 ± 5.4 to 11.1 ± 10.1 mL/s) and voided volume (from 119.9 ± 82.2 to 191.0 ± 140.1 mL) were only found in the onabotulinumtoxinA group.
