Surgical operation on 30 kidneys was carried out for branched renal calculi, with no operative mortality. Of 23 kidneys in which conservative surgical procedures were used, 83 percent are now stone-free. When all stones were successfully removed, cultures of urine were sterile in 80 percent of cases, but when fragments remained, no patient was infection-free. It was found that impaired renal function need not be a contraindication to surgical operation, and indeed that in five of seven patients with impaired renal function, serum creatinine levels either remained stable or improved. We believe that surgical removal is the most conservative management of branched renal calculi.
对30个肾脏进行了分支肾结石手术，无手术死亡病例。在采用保守手术方法的23个肾脏中，83%的肾脏现在已无结石。当所有结石都成功取出时，80%的病例尿液培养无菌，但当有结石碎片残留时，没有患者无感染。研究发现，肾功能受损不一定是手术的禁忌证，事实上，在7例肾功能受损的患者中，有5例血清肌酐水平保持稳定或有所改善。我们认为手术切除是分支肾结石最保守的治疗方法。
