Comparison of urodynamic parameters between the groups.

	Infused vol. (µl)	Void vol. (µl)	Pves max (mmHg)	Voiding efficiency (%)	Non-void contractions
Control	106 ± 11	109 ± 6	17.0 ± 0.5	105 ± 8	0.1 ± 0.1
Constipation	79 ± 5*	72 ± 7†	15.6 ± 2.0	99 ± 7	0.8 ± 0.2*

The constipation group showed a significant decrease in bladder capacity, voided volume, and a significant increase in the number of non-void contractions compared to the control group (N = 4 per each group). Mean ± SE, *p < 0.05 and ^†p < 0.005 vs. the control group, Pves max, maximum intravesical pressure at micturition.
