Abstract:
OBJECTIVE:To detect the levels of neutrophil gelatinase-associated lipocalin (NGAL), cystatin C (Cys-C ) in blood and the level of kidney injury molecule 1 (KIM-1) in urine in elderly patients with renal calculi at diff erent times, and to explore the eff ect of percutaneous nephrostolithotomy (PCNL) combined with flexible ureteroscopy (FU) on early postoperative renal function.
METHODS:A total of 46 patients with renal calculi were selected, and their blood or urine specimens were collected respectively at preoperative and postoperative 2, 12, 24, 48, and 72 h. The concentrations of NGAL, Cys-C, KIM-1 were detected.
RESULTS:The levels of NGAL and Cys-C began to increase respectively at postoperative 2 and 12 h, and reached peak at postoperative 12 to 24 h. There was significant difference in the levels of NGAL and Cys-C between the postoperative 12 and 2 h or between postoperative 48 and 24 h (all P<0.05). The levels of NGAL and Cys-C began to decline and eventually returned to preoperative levels respectively at postoperative 48 and postoperative 72 h. The KIM-1 began to increase at postoperative 2 h and peaked at postoperative 24 h, which was significant difference between the postoperative 24 and 12 h or postoperative 48 and 24 h (both P<0.05). The level of KIM-1 began to decline and eventually returned to preoperative levels at postoperative 48 h.
CONCLUSION:After the combined treatment of percutaneous nephrostolithotomy with flexible ureteroscopy, the concentrations of NGAL, Cys-C and KIM-1 are significantly increased, suggesting injuries on renal function. The time of renal tubular injury and recovery is earlier than that of renal glomerulus.
