To evaluate the clinical value of color Doppler flow imaging(CDFI)combined with real-time ultrasound monitoring in percutaneous nephrolithotomy(PCNL),the clinical data of 256 patients with renal/ureteral calculi trea-ted with PCNL from January 2021 to May 2022 were analyzed retrospectively.According to whether the puncture was turned on or not and color Doppler flow imaging was used,the patients were divided into two groups:ultrasound gray scale puncture group(observation group)and color Doppler flow imaging combined with ultrasound gray scale punc-ture group(control group).The establishment of intraoperative passage,operation time,intraoperative bleeding and flushing fluid dosage were compared between the two groups,and the stone removal rate and complications were ob-served after operation to evaluate the surgical effect.All the patients in the two groups completed the operation in I stage.There was no significant difference in the success rate of initial channel establishment(99.2%vs),channel establishment time(3.4±0.6)min vs(3.3±0.7)min,operation time(96.2±18.4)min vs(100.3±16.7)min,multi-channel(18.3%vs 21.5).The hemostatic rate of clamping nephrostomy(3.2%vs 0)and the amount of intraoperative irrigation solution[(13.8±4.1)L vs(12.3±2.6)L]were significantly different(P<0.05).There were significant differences in bleeding rate(5.6%vs 0.8%),perirenal hematoma(3.2%vs 0),blood transfusion rate(4.0%vs 0),interventional embolization rate(3.2%vs 0),hemoglobin decrease[(20.9±10.9)g/L vs(16.7±6.9)g/L]between the two groups.There was no significant difference in fever rate(10.3%vs 9.2%),pneumothorax and pleural effusion rate(0.8%vs 1.5%),and residual stone rate(7.9%vs 9.2%).Color Doppler flow imaging combined with real-time ultrasound monitoring in PCNL can effectively avoid damage to large branches of renal arteries,reduce the proportion of complications of PCNL bleeding,improve the success rate of puncture,reduce the rate of residual stones,and avoid complications such as organ injury.
