Curative effect observation of CT three dimensional reconstruction combined with color Doppler ultrasound of the percutaneous renal biopsy in inclined back rock bit

Abstract

Objectives To investigate the curative effect of CT three-dimensional reconstruction combined with color Doppler ultrasound of the percutaneous nephrolithotomy(PCNL) in inclined back rock bit. Methods A total of 104 patients with complex renal calculi who underwent PCNL in our hospital from May 2013 to June 2015 were selected and divided into two groups, according to whether the CT three-dimensional reconstruction combined with color Doppler ultrasound localization puncture. Differences of the surgery condition, postoperative renal blood flow, postoperative stone clearance rate and surgical complications were compared between the two groups. Results The operation time, puncture time, hemoglobin loss in the observation group were lower than the control group, and the difference was statistically significant (P 0.05). The stone clearance rate in the observation group (46 cases, 85.18%) was higher than that in the control group (29 cases, 58%), and the difference was statistically significant (P<0.05). The incidence of postoperative complications in the observation group(3, 5.56%) was lower than that in the control group (10 cases, 20%), and the difference was statistically significant(P<0.05). Conclusions CT three-dimensional reconstruction combined with color Doppler ultrasound localization puncture of PCNL in inclined back rock bit for treatment of complex renal calculi is better than the simple CT three-dimensional reconstruction localization puncture.
