Figure 2: Surgical methods between groups. (a) In group 1, if the infundibular angle was sharp or the infundibular width was narrow, it was favored to cause wider laceration in renal parenchyma in order to reach another calyx. (b) In group 2, the other tracts were smaller than the main tract we first punctured. In some cases, the single incision of multiple-tract approach decreased the muscular and parenchyma laceration on the kidney
