目的:探讨双重定位法(联合B超、X线进行定位)在经皮肾镜取石术(PCNL)治疗鹿角形肾结石中的应用价值。方法:回顾性分析2008年12月~2013年5月间采用双重定位法的PCNL术治疗136例鹿角形肾结石的临床资料。其中完全鹿角形结石79例,不完全鹿角形结石57例。结果:136例均手术成功。其中一期手术89例次,二期手术45例次,三期手术14例次,单通道72例次,双/多通道76例次。平均手术时间79.8min。结石清除率91.2%(135/148)。无严重并发症病例。结论:应用双重定位法的PCNL术在治疗鹿角形肾结石方面具有有效、安全的特点,能提高清石率,降低并发症发生概率,在有条件实施的情况下值得推荐。
Objective: To investigate the value of dual localization (combined with B-ultrasound and X-ray) in the treatment of antler kidney stones with percutaneous nephrolithotomy (PCNL). Methods: The clinical data of 136 cases of deer horns kidney stones treated with PCNL double positioning method between December 2008 and May 2013 were retrospectively analyzed. Among them, 79 cases were completely staghorn, 57 cases were incomplete staghorn. Results: All 136 cases were operated successfully. There were 89 cases of primary surgery, 45 cases of secondary surgery, 14 cases of tertiary surgery, 72 cases of single-channel and 76 cases of double / multi-channel. The average operation time 79.8min. Stone clearance rate was 91.2% (135/148). No serious complications. CONCLUSION: PCNL with double positioning method is effective and safe in treating antler kidney stones. It can improve the rate of clear stones and reduce the probability of complications, which is worth recommending under the condition of implementation.
