Clinicopathological characteristics and typing of multilocular cystic renal neoplasm of low malignant potential

Table 2 Comparison of postoperative pathological positive rates between simple renal cysts and cysts combined with renal tumors diagnosed preoperatively, n (%)

Index1	Group	Benign	MCRNLMP	P value
Preoperative diagnosis	Simple renal cyst (type I)	735 (98.52)	11 (1.48)	< 0.001
	Complex renal cyst (type II)	397 (94.74)	22 (5.26)
	Cysts combined with renal tumors (type III)	312 (87.89)	43 (12.11)

¹The above results with χ² test showed significant difference in the pathological positive rate of various preoperative diagnosis (P < 0.001).
