| 摘 要： | Objective To evaluate the sickle renal parenchyma incision for the removal of complex staghorn renal calculi. Methods Sickle parenchyma incision was used to remove stones in 37 patients with complex staghorn renal calculi. The procedure was as follows; the kidney was disected free and the pelvis within sinus renalis was isolated. Two of botton 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 (Brodie' s line) 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 major calyx through the middle major calyx to the plane of upper major calyx. The shape of this incision appeared like a sickle. The renal parenchyma and each calyx along this incision were opened and so was all the stones could then be easily removed. The calyces could well be observed. Results The calculi were completely removed in all the 37 cases. 21 neede
