ObjectiveTo investigate clinical efficacy of percutaneous nephroscope in treatment of patients with severe acute pancreatitis (SAP). MethodsEighty-six patients with SAP in this hospital from August 2012 to November 2015 were selected, which were divided into percutaneous nephroscope treatment group (43 cases) and laparotomy treat-ment group (43 cases) according to the difference of therapy modality. The conventional drug therapy was performed for all of them. The postoperative recovery, content of serum C reactive protein (CRP) on day 14 after operation, and post-operative complications were observed in these two groups. Results① The abdominal pain relief time, postoperative bowel sounds recovery time, normal body temperature recovery time, and postoperative hospitalization time in the percu-taneous nephroscope treatment group were significantly shorter than those in the laparotomy treatment group (P<0.05). ② The contents of serum CRP in the percutaneous nephroscope treatment group and in the laparotomy treatment group on day 14 after operation were significantly lower than those on day 1 before operation[(8.35±2.13) mg/L versus (31.44±3.45) mg/L, P<0.05; (16.42±2.44) mg/L versus (32.09±2.98) mg/L, P<0.05]. On day 14 after operation, the content of serum CRP in the percutaneous nephroscope treatment group was significantly lower than that in the laparotomy treat-ment group[(8.35±2.13) mg/L versus (16.42±2.44) mg/L, P<0.05]. ③ The incidence rate of postoperative complications in the percutaneous nephroscope treatment group was significantly lower than that in the laparotomy treatment group[14.0% (6/43) versus 32.6% (14/43), P<0.05]. ConclusionPercutaneous nephroscope in treatment of patients with SAP is effect, it has advantages of shorter hospital stay and early recovery, which could reduce incidence of postoperative complications, and it's mechanism might be related to systemic inflammatory response.
目的 总结超选择性肾动脉栓塞治疗经皮肾镜取石术后严重出血的临床经验。 方法 回顾分析2009年10月－2012年11月行经皮肾镜取石术后发生严重出血的6例（2.74%）患者的临床资料和对其进行超选择性肾动脉栓塞术的血管造影表现和栓塞疗效。 结果 患者平均年龄67岁，经皮肾镜取石术后急性出血1例，迟发出血5例，均有体外冲击波碎石史或糖尿病、高血压病史。肾动脉造影显示损伤动脉为肾后下段动脉、肾下段动脉分支，表现为假性动脉瘤5例，动静脉瘘1例。使用弹簧圈或聚乙烯醇颗粒超选择性栓塞，栓塞后出血无一例复发。随访6个月，5例肾功能未见下降，1例受损。 结论 经皮肾镜术后严重出血与术中动脉损伤有关，采用超选择性肾动脉栓塞术能够达到迅速止血、尽可能保全患肾功能、有效挽救生命的诊疗效果。
目的 探讨孤立肾肾结石经皮肾镜取石（PCNL）术并发感染性休克的护理。 方法 回顾性分析2010年3月－2012年10月5例孤立肾肾结石患者行PCNL术后并发感染性休克的临床资料，对患者术后出现的休克及时补足血容量，使用有效的抗生素，早期足量应用激素、血管活性药物，同时加强心理疏导、健康教育等护理措施。 结果 5例患者体温均在3 d内降至正常；血管活性药物平均使用时间为1.8 d （2～4 d）；1例因血氧饱和度＜80%，血压＜85/50 mm Hg（1 mm Hg=0.133 kPa）转往重症监护病房行呼吸机辅助呼吸2 d后呼吸循环功能改善；另1例同时出现少尿无尿，及时行血液透析，第4天尿量逐渐恢复；5例患者均痊愈出院。 结论 感染性休克是PCNL术后最危险的并发症之一，对其采取积极预防、及早发现、及时有效的治疗和护理等措施，可有效促进患者康复。
ObjectiveTo explore the perioperative nursing mode for percutaneous nephrolithotomy (PCNL). MethodsA total of 866 patients with PCNL having undergone lithotripsy between January 2012 and December 2013 in our hospital were included in our study. Before surgery, they received position training, health education and psychological nursing. After surgery, patients received an integral medical wound care and pipeline management, as well as management of infectious shock and intercostal neuralgia. At the same time, we gave them dietary guidance and other health guidance. ResultsAll the patients were successfully discharged from hospital. Postoperative infection rate was 2.4%, septic shock rate was 0.2%, bleeding rate was 2.2%, urinary leakage rate was 1.5%, the rate of pneumothorax was 0.6%, subcutaneous emphysema rate was 0.3%, and intercostal neuralgia rate was 0.6%. The average hospital stay was (11.2±2.8) days. ConclusionThe innovative nursing mode and techniques have great significance on the success of PCNL surgery.
Objective To assess the efficacy and safety of the tubeless approach with a ureteral stent versus nephrostomy tube for postoperative drainage following percutaneous nephrolithotomy, and to provide guidance for clinical practice. Methods Randomized controlled trials (RCTs) were identified from PubMed (1966 to August 2008), Ovid (1966 to August 2008), Embase (1966 to August 2008), The Cochrane Library (Issue 3, 2008) and CBM (1978 to 2008). We also handsearched for relevant published and unpublished reports and check their references. The quality of the included trials was evaluated by two reviewers. We used The Cochrane Collaboration’s RevMan 5.0.16 software for meta-analysis. Results Eight studies involving 507 patients were included. We divided the patients into three groups: small (8~9 Fr), medium (16~18 Fr) and large (20~24 Fr) according to the diameter of nephrostomy tube for the analysis. Our meta-analyses showed: ①Hospital stay (hours): There was no statistically significant difference between tubeless and small bore tubes, but a difference was found in the comparison of tubeless versus medium and large bore tubes [WMD (95%CI) –32.4 (–33.64, –31.16) and –39.07 (–67.75, –10.39), respectively]; ② Puncture site urinary leakage: No statistically significant difference was found between tubeless and small bore tubes, of between tubeless versus medium tubes [RR= 0.07, 95%CI (0.00, 1.15), P=0.06]; ③ Visual analogue scale scores for postoperative pain on Day 1: There was no statistically significant difference between tubeless and small bore tubes, but there was a difference in tubeless versus medium and large bore tubes [MD (95%CI) –2.80 (–2.94, –2.66) and –2.04 (–2.29, –1.79), respectively];④No statistically significant difference was found in transfusion, fever or infection and operating time between tubeless and any size of nephrostomy tube. Conclusion No statistically significant difference between tubeless versus small bore tubes is found for any of the outcome measurements we analysed. Compared with medium and large bore tubes, tubeless PCNL of ureteral stent could reduce hospital stay, urine leakage and postoperative pain without an increase in complications. There is a moderate possibility of selection bias, performance bias and publication bias in this review, because of the small number of the included studies, which weakens the strength of the evidence of our results. Better evidence from more high-quality randomized controlled trials is needed.
Objective To systematically review the effectiveness and safety of flexible ureteroscope lithtripsy (fURL) and percutaneous nephrolithotomy (PCNL) in treating renal calculus. Methods Such databases as MEDLINE, EMbase, The Cochrane Library, CNKI, CBM, VIP, and WanFang Data from January, 1990 to August, 2012 were searched to comprehensively collect the clinical trials that compared fURL and PCNL in treating renal calculus. Two reviewers independently screened studies according to exclusion and inclusion criteria, extracted data, and assessed the methodological quality. Then, meta-analysis was performed using RevMan 5.1 software. Results Eight non-randomized controlled trials involving 536 patients were included. The results of meta-analysis showed that, PCNL was better than fURL in stone clearance (OR=0.26, 95%CI 0.15 to 0.46), but fURL was better than PCNL in postoperative pyrexia (OR=0.1, 95%CI 0.42 to 3.35), the incidence of blood transfusion (OR=0.17, 95%CI 0.03 to 1.00), and the duration of hospitalization (P=0.45, I2=0%). Conclusion Current evidence has proved that PCNL is better than fURL in decreasing stone clearance, fURL is better than PCNL in complication, the duration of hospitalization, and medical costs.
