A newly devised technique for nephrolithotomy was applied in 29 patients with renal calculi, and good results were obtained. The principle of this new approach is the method of suturing the renal pelvis and the renal capsule. In this procedure paired hemostatic sutures are inserted to appose the cut surfaces and then ligated. The time for the disappearance of macroscopic and microscopic hematuria and the ischemic time needed for operation were measured and computerized tomography was performed in the 29 cases operated on by this new method. The results were compared with those obtained from 41 patients treated by conventional vertical interrupted parenchymal suture. These clinical data as well as microangiographic findings in animals have shown that this new procedure is far superior to that using vertical interrupted parenchymal sutures and is simple to use with better preservation of renal function when compared with anatrophic nephrotomy.
