Comparison of the Effect of Negative Pressure Suction Sheath and Ordinary Flexible Endoscope Sheath in Ureteroscopic Lithotripsy
Objective:To observe and compare the application effect of negative pressure suction sheath and ordinary flexible endoscope sheath in the treatment of flexible ureteroscopic lithotripsy. Methods:106 patients who underwent flexible ureteroscopic lithotripsy in our hospital from May 2022 to May 2023 were selected as the clinical objects. According to the methods used during the operation,they were included in the conventional group (n=53) and the study group (n=53). The patients in the conventional group used ordinary flexible ureteroscopic sheath during the operation,and the patients in the study group used negative pressure suction sheath during the operation. The success rate of sheath placement,stone removal effect,perioperative indicators[intraoperative operation time,perioperative blood loss,hospital stay],intrapelvic pressure,postoperative immediate infection level[white blood cell count (WBC),C-reactive protein (CRP),procalcitonin (PCT)],postoperative visual analogue scale (VAS) score,and complication rate were compared between the two groups. Results:There was no difference in the success rate of sheath placement and stone clearance rate between the study group and the conventional group (P>0.05). The intraoperative operation time,perioperative blood loss and hospital stay of the study group were less than those of the conventional group (P<0.05). The intrarenal pressure and the expression levels of WBC,CRP and PCT immediately after operation in the study group were significantly lower than those in the conventional group (P<0.05). The VAS scores of the study group at 2h,6h,12h and 24h after operation were lower than those of the conventional group (P<0.05). There was no difference in the incidence of postoperative complications such as increased body temperature,bleeding,ureteral injury,renal colic,septic shock between the study group and the conventional group (P>0.05). Conclusion:The application of negative pressure suction sheath and ordinary soft endoscope sheath in the treatment of flexible ureteroscopic lithotripsy can effectively and safely remove stones,but the negative pressure suction sheath can reduce the renal pelvis pressure,reduce intraoperative bleeding,speed up intraoperative operation,relieve pain,and reduce perioperative infection.
