Comparison of the pre-post-change of IPSS between the two groups.

Item (pre-post-change)	DI group (n = 60)	SI group (n = 60)	value
Total IPSS	10.52 ± 6.71	5.33 ± 5.48	<0.001
Incomplete emptying	2.03 ± 1.94	1.62 ± 1.80	0.226
Frequency	1.72 ± 1.87	0.65 ± 1.66	0.001
Interruption	1.25 ± 2.18	0.50 ± 2.18	0.062
Urgency	1.58 ± 1.94	0.40 ± 2.07	0.002
Weak stream	1.22 ± 2.42	0.78 ± 1.87	0.274
Hesitancy	1.55 ± 2.20	0.95 ± 2.20	0.138

Notes: DI group: EA with deep insertion about 60–75 mm. SI group: EA with shallow insertion about 25–40 mm. IPSS: International Prostate Symptom Score; IPSS contains 7 urinary factors including incomplete emptying, frequency, interruption, urgency, weak stream, hesitancy, and nocturia. value: differences in degree of change between two groups.
