Abstract:
Objective To evaluate the arc renal parenchyma incision of pelvis within renal sinus and renal posterior lib for the removal of complex staghorn renal calculi.Methods Arc renal parenchyma incision of pelvis within renal sinus and renal posterior lib was performed to remove stones in 86 cases (97 sides) with complex staghorn renal calculi.Among the 86 cases,42 had stones on the right side;33,on the left side;11,on bilateral sides.Seventeen cases had concomitantly calculi in the ureter,and 54 had calculi in upper and mid calyx or multiple renal calculi.As for comorbidity,11 cases had hypertensions;4,diabetes; and 5,hepatitis B.Twenty-five cases had renal insufficiency,with BUN of 12.3 -76.0mmol/L and Cr of 231 -1721?mol/L.The procedure was performed as follows:the kidney was dissected free and the pelvis within renal sinus was isolated.Two rows of bottom style sutures were made on the renal parenchyma with 2-0 plain catgut along mid-lower 1/3 of the dorsal surface of kidney free of vessels from the renal posterior lib to the plane of lower major calyx.The renal parenchyma was opened.Then,the incision was developed from the plane of lower through the middle major calyx to the plane of upper major calyx.The renal parenchyma and mid-low calyx along the incision were opened,suturing while incising,so that all the stones could be easily removed with hook.Results The calculi were completely removed in all 86 cases (97 sides).The opera- tive time was 105-187min ( mean,129min).The intraoperative blood loss was 120-460 ml ( mean,220 ml).Forty-three cases needed intraoperative blood transfusion of 120 -200 ml (mean,140 ml).One month after operation,KUB+IVU and ultrasonic findings were normal with improved hydronephrosis,no intrarenal stricture and no residual calculi.Conclusions This procedure has the advantages of less bleeding,slight impairment of renal function,simple handling,clear operative field,high clearance rate,therefore is indica- ted for the removal of complex staghorn calculi.
