Table 2. The mean Q_max and post voiding residual urine values in preoperative and postoperative follow-up.

	Pre-op (n=28)	Post-op	After stent removal				p value
		3 months (n=25)	3 months (n=23)	1 year (n=15)	2 years (n=9)	3 years (n=4)
Q_max (mL/sec)	6.24^*	19.12	19.01	18.40	18.56	17.26	<0.001
PVR (mL)	142.51^*	40.12	44.14	46.85	41.56	48.89	<0.001

PVR = Post voiding residual urine;

There were significantly differences between pre-op and post-op (both before and after stent removal)

Q_max and PVR values. There were no differences between post-op Q_max and PVR values.
