目的 探讨经皮微创技术应用股骨近端解剖锁定钢板治疗高龄骨质疏松粗隆间骨折的治疗。方法 我院自2009年12月—2013年6月共收治高龄骨质疏松粗隆间骨折56例,男35例,女21例;年龄76～94岁,平均81岁。所有患者应用股骨近端解剖锁定钢板通过经皮微创置入技术治疗。根据Harris髋关节功能评分对治疗效果进行评定。结果 56例手术时间30～90 min,平均45 min;术中失血量70～250 mL,平均110 mL。全部患者获随访,时间6～13.5个月,平均9.5个月。X线骨折愈合时间3～6个月,平均3.5个月。其中优41例,良12例。结论 对于高龄骨质疏松患者粗隆间骨折,采用经皮微创置入股骨近端解剖锁定钢板内固定治疗,具有手术创伤小、出血少、安全可靠等优点,有良好的临床应用价值。

Objective To study the application of proximal femur anatomic locking plate with minimally invasive percutaneous plate osteosynthesis (MIPPO) techniques in the treatment of senile osteoporosis curative effect of intertrochanteric fractures in elderly patients. Methods We have treated 56 elderly patients of senile osteoporosis intertrochanteric fractures in December 2009 to June 2013, including 35 male and 21 female cases, aged 76~94, the average of 81. All patients were applied in the proximal femur anatomic locking plate with minimally invasive percutaneous plate osteosynthesis technology according to Harris hip joint function scale curative effect. Results 56 cases of operation time 30~90 min, an average of 45 min. Intraoperative blood loss was 70~250 ml, an average of 110 ml. All patients received follow-up from 6 to 13.5 months, an average of 9.5 months. The X-ray fracture healing time was from 3~6 months, 3.5 months on average. According to the Harris hip joint function scale: 41 cases was excellent, 12 cases was good. Conclusion For the senile osteoporosis intertrochanteric fracture, using the proximal femur anatomic locking plate with minimally invasive percutaneous plate osteosynthesis technology can make minimal trauma, less bleeding reliable fixation,and has good clinical application value.

       目的   探讨无管化微创PCNL（经皮肾镜取石术）治疗嵌顿性输尿管上段结石的效果。方法   将中山大学附属第一医院惠亚医院2019年12月—2021年12月收治的95例嵌顿性输尿管上段结石患者按照随机数字表法分组，给予对照组47例患者经尿道输尿管镜碎石术（TURL）治疗、观察组48例患者无管化微创PCNL治疗，观察两组手术一般状况、血清学指标、肾脏血流动力学以及并发症发生情况。结果   观察组手术时间、术后血尿以及住院时间均短于对照组，观察组术中出血量少于对照组，观察组结石清除率高于对照组（P＜0.05）；术后1 d观察组肾损伤分子-1（KIM-1）、中性粒细胞明胶相关脂脂质运载蛋白（NGAL）以及胱抑素C（Cys-C）水平低于对照组（P＜0.05）；两组肾动脉收缩期血流速度（Vs）以及舒张末期血流速度（Vd）对比差异无统计学意义（P＞0.05）；观察组并发症发生率（4.16%）低于对照组（19.15%）（P＜0.05）。结论   无管化微创PCNL可改善嵌顿性输尿管上段结石手术一般状况，减轻患者肾脏损伤，提高结石清除率，不影响肾脏血流，且并发症更少。

       Objective  To explore the effect of tubeless minimally invasive（percutaneous nephrolithotomy，PCNL）in the treatment of impacted upper ureteral stones．Methods  A total of 95 patients with impacted upper ureteral stones admitted to our hospital from December 2019 to December 2021 were grouped according to the random number table method．Control group of 47 cases were treated with transurethral ureteroscopy lithotripsy（TURL），48 patients in the observation group were given tubeless minimally invasive PCNL treatment．The general surgical conditions，serological indicators，renal hemodynamics and complications of the two groups were observed．Results  The operation time，postoperative hematuria and hospitalization time of the observation group were shorter than those of the control group，the intraoperative bleeding volume of the observation group was less than that of the control group，and the stone free rate of the observation group was higher than that of the control group（P＜0.05）．One day after surgery，the levels of kidney injury molecule-1（KIM-1），lipocalin（NGAL）and cystatin C（Cys-C）in the observation groupwere lower than those in the control group（P＜0.05）；the renal artery systolic blood flow velocity（Vs）and end-diastolic blood flow velocity（Vd）had no statistical significance（P＞0.05）；the incidence of complications in the observation group（4.16%）was lower than that in the control group（19.15%）（P＜0.05）．Conclusions  Tubeless minimally invasive PCNL can improve the general conditions of surgery，reduce kidney damage，increase stone free rate，does not affect renal blood flow，and has fewer complications．
