摘要
目的探讨一期经皮肾镜取石术（PCNL）联合二期输尿管软镜手术（retrogradeintra—renalsurgery，RIRS）治疗孤立肾复杂性结石的临床疗效。方法回顾性分析2008年4月至2012年5月收治的21例孤立肾鹿角形结石或多发性结石患者的临床资料，男15例，女6例。年龄19～76岁，平均45岁。其中先天性孤立肾3例，对侧。肾切除孤立肾9例，功能性孤立肾9例。鹿角形结石13例，多发性结石8例。结石最大径3．8～6．8cm，平均4．6cm。全麻下，行C臂x线定位下PCNL，采用第四代EMS超声碎石系统碎石。术后常规留置6F双J管及肾造瘘管。术后1d复查KUB及CT评估残留结石部位及大小。PCNL术后3～30d行RIRS。全麻下，先取截石位，拔除双J管，在C臂x线引导下置入斑马导丝及12～14F输尿管软镜鞘。采用OlympusP5纤维软镜或者电子软镜及200μm钬激光光纤（8～20w）碎石。对于〈2cm残留结石，粉碎后自行排出或套石篮取出。对于〉2cm的残留结石，以钬激光击碎结石后，用套石篮将较大的碎石片转移至肾盂，改俯卧位，行二期PCNL取石，术后均留置双J管。术后1d复查KUB，术后1～2d拔除肾造瘘管，2～3周拔除双J管。术后3个月复查KUB或CT，评估结石清除率。结果本组21例PCNL中采用单通道18例，双通道2例，3通道1例。手术时间45～175min，平均95min。残留结石大小1．0～3．512m，平均1．9cm。结石残留在下盏7例、上盏及下盏4例、中盏及下盏6例、上中下盏均残留4例。PCNL术后发热2例，1例迟发性出血患者采用超选择性肾动脉栓塞治愈。RIRS手术时间35～95min，平均72min。RIRS术后1d结石清除率为85．7％（18／21）。3例残留结石患者中，1例经二期PCNL、2例经ESWL治疗后，结石清除率95．2％（20／21）。2例RIRS术后发热和输尿管石街形成，采用输尿管硬镜取石术治愈。术后3个月随访，患者肌酐为88～230μmol／L，平均（138．7±38．3）μmol／L，平均下降了（16．8±25．4）μmol／L，肾功能改善15例，稳定5例，恶化1例，与术前比较差异有统计学意义（P〈0．05）。结论一期PCNL联合二期RIRS治疗孤立肾复杂性结石安全有效，出血量少，可有效保护肾功能。
Objective To evaluate the efficacy and advantages of the technique by combined PCNL and retrograde intrarenal surgery （RIRS） in a second stage to treat the complex renal stones in solitary kid- ney cases. Methods PCNL most with a single 18 -24 F tract was performed first and RIRS was carried out at a second stage in solitary kidneys of 21 patients, of which congenital in 14.3% （3 cases）, contralat- eral nephrectomy in 42.8% （9 cases） , and functional solitry kidneys in 42.8% （9 cases）. Of the 21 pa- tients, the average age was 45 years with 15 males and 6 females. The stones were 8 multiple, 6 partial stag-horn, and 7 complete staghorn with a mean size of 4.6 （3.8 - 6.8） cm. Results Of the 21 PCNL cases, a single tract, double, triple tracts were established in 18 （85.7%） , 2 （9.5%） , 1 （4.8%） cases, re- spectively. Mean operation time of PCNL was 95 （45 - 175） min. After 1 day of PCNL, all case had resid- ual stones with a mean size of 1.9 （ 1.0 - 3.5 ） cm. Two case occurred fever after PCNL and one case pres- ented bleeding resolved by selective renal artery embolization. The mean operation time of RIRS was 72 （35-95） min. Stone-free rate after RIRS was 85.7% （18/21）. The final stone free rate increased to 95.2% （20/21） after one case received a second-look PCNL and two cases accepted ESWL. Two cases oc- curred fever and steinstrasses after RIRS resolved by rigid ureteroscopy. At the 3 months follow-up, renal function became stable, improved and worse in 71.4% （n=15）, 23.8% （n=5）, and 4.8% （n=l） of patients. Conclusions PCNL combined with RIRS could be an effective and safe option for complex stones in solitary kidneys with less bleeding, reduced tracts, minor complications and good renal function preservation.
