Preoperative and postoperative renal function in a case undergoing retroperitoneal laparoscopic ureterolithotomy

	Preoperative value	Postoperative value
Serum creatinine (mg/dl)	0.87 ± 0.31	0.78 ± 0.30	N.S.
eGFR (ml · min-1 · 1.73 m-2)	66.0 ± 18.39	75.2 ± 23.2	N.S.
Affected/contralateral renal 99mTc-MAG3 clearance (compared to the preoperative value, %)	-	101.8 ± 5.5	N.S.

99mTc-MAG3, 99mTc-mercaptoacetyltriglycine, eGFR, estimated glomerular filtration rate; N.S., no significant difference.
