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.
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 We also handsearched for relevant published and unpublished reports and check their references.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.

Methods From September 2007 to October 2010, 138 patients with upper urinary tract calculi were treated with mini PCNL with holmium laser under the conduction by type-B ultrasonography. Of the 138 cases, 64 patients had staghorn calculi, 38 had single renal pelvis or renal calyx stones, eight had bilateral renal calculi, 28 had upper-ureteral calculi, and two had solitary kidney calculi. Results Successful stone removal was achieved in 136 cases, among which there were 95 cases of stage-one nephrolithotomy (double tracts were used in five cases) and 41 cases of sfage-two neploolithotomy. Two cases were changed to open operation due to failures of percutaneous nephrolithotory. Extracorporeal shock-wave lithotomy was used in 27 cases after operation. The average stone removal rate was 78.9% (109/138). The average operation time was 112 minutes. The average hospital stay was 10 days. The average nephrostomy tube stay was four days. The average double J tube stay was four weeks. Five patients needed blood transfusion in operations due to a large amount of blood loss. Eleven patients suffered from massive hemorrhage one week after operation and blood transfusion was performed in three patients. Urine exosmosis happened in 12 cases. And there were seven cases of high fever (gt;39 ℃) after operation. Follow-up was done for 98 patients accompanied by hydronephrosis for a time period ranged from three to six months averaging at four months. Hydronephrosis disappeared in 24 patients, alleviated in 68 cases, and did not change in six cases. Twenty-two cases of residual calculi were followed up for a period ranged from four to nine months averaging at six months. Enlarged calculi occurred in six cases and no change happened to the calculi in 16 cases. Eighty-seven patients without residual calculi were followed up for 12 months, and there were seven cases of reoccurrence. Conclusion Treatment of upper urinary tract calculi with minimally invasive percutaneous nephrolithotomy with holmium laser is a simple and safe method with little injury, quick recovery, few complications and satisfactory results.
【摘要】 目的 探讨微创经皮肾镜碎石术后并发感染性休克的原因和防治措施。 方法 回顾性分析2005年1月-2010年12月5例经皮肾镜术300例，其中术后并发感染性休克5例的临床资料。男1例，女4例，均表现为术后2~8 h内出现寒战、高热、烦燥不安，血压降至80/50 mm Hg（1 mm Hg=0.133 kPa）以下，心率超过120次/min。所有患者均行抗感染和抗休克治疗。 结果 所有患者均在72 h内停用升压药，1周内体温及血常规恢复正常，术后15 d治愈出院。 结论 感染性休克是微创经皮肾镜碎石术严重的并发症之一，术前有效抗感染、术中低压灌注、术后加强生命体征的监测、早期发现并合理处理，可有效防治感染性休克的发生。【Abstract】 Objective To explore the etiology and treatment of septic shock after percutaneous nephrolithotomy. Methods From Janurary 2005 to December 2010, the clinical data of five patients with septic shock after percutaneous nephrolithotomy in our hospital were retrospectively analyzed. The patients, including one male and four females, had chillness and high temperature after the nephrolithotomy. The blood pressure decreased to under 80/50 mm Hg （1 mm Hg=0.133 kPa）, and the heart rate was more than 120 per minute. All patients underwent anti-shock and anti-infection therapies rapidly. Results Five patients were cured in the end, their temperature and blood routine tests returned to normal within one week. Conclusions Septic shock is one of the serious complications after percutaneous nephrolithotomy. Effective preoperative preparation, low pressure irrigation during operation, early diagnosis and treatment postoperatively are the effective ways to prevent the septic shock.
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.
