Clinical Study Of Percutaneous Nephrolithotomy In Prone-Split Leg Position For Upper Urinary Calculi

ObjectiveIn order to investigate the feasibility and advantages and disadvantages of prone-split leg position percutaneous nephrolithotomy in the treatment of upper urinary calculi,we compared it with the prone position percutaneous nephrolithotomy.MethodsA total of 200 patients who underwent percutaneous nephrolithotomy for upper urinary calculi in our hospital from December 2018 to December 2020 were retrospectively analyzed.In the observation group,100 patients were given prone-split leg position.After anesthesia,the patient was placed in the prone position,the ureteral catheter was placed first,then a percutaneous access tract was established and the calculi were crushed by holmium laser or pneumatic ballistics.In the control group,100 patients were given a prone position.After anesthesia,the patient was placed in the lithotomy position first,and the ureteral catheter was placed,then the patient was placed in the prone position for percutaneous nephrolithotomy.The operation time,length of hospital stay,stone-free rate,changes in hemoglobin and serum creatinine,complication rate between the two groups were compared.ResultsThe mean operation time of the observation group was 67.01±33.40 min,and the mean operation time of the control group was 91.15±33.70 min,the difference was statistically significant(P<0.005).There were no significant differences in length of hospital stay,stone-free rate,changes in hemoglobin and serum creatinine,complication rate between the two groups(P>0.05).ConclusionIn the treatment of upper urinary calculi,the operation time of prone-split leg position is shortened than the prone position of percutaneous nephrolithotomy,and it can be combined with retrograde ureteroscopic lithotripsy and catheterization,which has obvious advantages and feasibility.
