Efficacy And Safety Of Anterior Calyces Access PCNL At Oblique Lithotomy Position

Objective: To investigate the efficacy and safety of PCNL by establishing percutaneous renal passage through anterior calyx in oblique position.Methods:72 cases of inclined supine position PCNL surgery form June2019 to February 2020,according to patients with preoperative kidney CT,intravenous renal pelvis and oblique supine position,according to the patient’s neponential fistula The location is divided into two groups of A,B,and the group A is a total of 32 cases;Group B is a renal,40 cases,and intraoperative kinemate Fetraway,postoperative recording operation time,number of renal puncture,postoperative blood routine,kidney CT,abdominal flat.Compare the first stage of calculus clearance,mean syndrome and fever,infection,surrounding organ(liver,spleen)and other safety indicators.Results: Two groups of gender,age,body mass index,surgical side,stones maximum diameter,calculus complexity,and nephrolid water have no significant statistical difference(P> 0.05);two groups of patients an average stone clearance rate,average Surgery time,average postoperative hospitalization time,mean renal puncture fistula,fever,mean hemoglobin change value,renal hematoma,blood transfusion rate,surrounding organ(liver,intestine,spleen)injury,pleural effusion,sepsis difference without statistics Learning significance(P> 0.05),no kidney bleeding during surgery,no renal artery hemostasis case,no colon and spleen injury,1 case of liver injury in patients with the front group(3.1%),after conservative treatment cure discharge.Conclusions: 1.The stone removal efficiency of the anterior approach PCNL in the oblique supine position is similar to that of the posterior group approach PNL;2.Using the "fornix-calyceal neck axis" method for anterior group PCNL will not increase the risk of renal hemorrhage;3.The risk of liver injury in PCNL via anterior approach may be high.
