Abstract:
【Objective】 To compare the clinical application value of controllable negative pressure suction outer sheath and ordinary flexible endoscope outer sheath in flexible ureteroscopic lithotripsy with holmium laser in the treatment of renal calculi less than or equal to 2 cm in diameter. 【Methods】 A total of 85 patients with renal calculi were selected and randomly divided into negative pressure group (n=45) and ordinary group (n=40). The operation time, complications, infection indexes 2 h after operation, adverse reactions, treatment efficacy and stone-clearance rate were compared between the two groups. 【Results】 The sheath was successfully implanted and holmium laser lithotripsy was performed in both groups. The negative pressure group had significantly shorter operation time than the ordinary group [(43.3±4.9) min vs. (66.2±5.8) min, P<0.05] . There were 1 case of renal pelvis perforation and 1 case of ureteral laceration in the ordinary group (P>0.05). The increase of infection indexes (procalcitonin and leukocyte) 2 h after operation were significantly lower in the negative pressure group than in the ordinary group (P<0.05). The efficacy in the negative pressure group was 91.11% (41/45) and the stone-clearance rate was 95.56% (43/45), which were significantly better than those in the ordinary group (72.50% (29/40) and 80% (32/40), respectively. The total incidence of adverse reactions such as renal colic, gross hematuria and ureteral stone street was higher in the ordinary group than in the negative pressure group (P<0.05). 【Conclusions】 Controllable negative pressure suction sheath in flexible ureteroscopic lithotripsy is more effective, as the circulation perfusion keeps the operation field clear, reduces the operation time and improves the stone-clearance rate, while the negative pressure suction lowers the pelvis pressure to prevent infectious urine from entering the blood.
