Data are reported as median (min-max/range).

Q_max: Maximal flow rate (mL/sec); PVR: Post-void residual urine (mL).

^*Q_max; Preoperative versus 1, 6, 12 months postoperative: statistically significant (p<0.001).

^**PVR; Preoperative versus 1, 6, 12 months postoperative: statistically significant (p<0.001).
