	Total (N. = 135) Median IQR	Lap (N. = 60)		Open (N. = 75)		Mann Whitney test	P value
	Total (N. = 135) Median IQR	Median	IQR	Median	IQR	Mann Whitney test	P value
Hospital stay	4 (3–5)	3.00	2.00–3.00	4.00	4.00–5.00	8.282	< .001 (HS)
Operative time	125 (122–138)	134.50	124.00–141.00	124.00	120.00–130.00	3.623	< .001 (HS)
Warm ischemic time	22 (20–26)	22.00	20.00–26.00	22.00	20.00–25.00	.936	.349
Estimated blood loss	150 (100–200)	125	100–200	160	120–400	3.21	< .001 (HS)

Bold values indicate the accepted level of significance (S) was (p < 0.05), p ≤ 0.001 was considered highly statistically Significant (HS), and p > 0.05 was considered Non statistically Significant (NS)
LPN laparoscopic partial nephrectomy, OPN open partial nephrectomy, HS highly significant
