The experience on management of abnormal blood vessels in 128 cases of donor kidney during the tailoring operation was reported. The various techniques used for different types of abnormal arteries and veins, and the critical points which should be paid attention to have been discussed. It was concluded that the multiple renal arteries should be treated in a single renal artery and anastomosed with internal iliac artery or/and external iliac artery. The appropriate management given to abnormal renal blood vessels during the tailoring operation may shorten the warm ishemia time, ensure the renal blood supply, reduce the renal vasular complication, and promote the recovery of renal function.
Studies of evidence-based medicine have provided much important evidence, clarified problems, and guided the clinical practice in the treatment of renal diseases. As examples, several therapeutic problems in renal hypertension, renal anemia and low protein diet for the patients with chronic kidney disease are discussed in this paper.
Objective To evaluate the safety of mycophenolate mofetil (MMF) versus azathioprine (AZA) for rejection after renal transplantation. Methods We searched MEDLINE (1966 to Jun. 2004), EMBASE (1984 to Jun. 2004), The Cochrane Library (Issue 2, 2004) and Chinese Biomedical Database (CBM, 1979 to Jun. 2004). Randomized controlled trials (RCTs) comparing MMF with AZA for rejection after renal transplantation were included. The quality of included studies such as randomization, blinding, allocation concealment was evaluated and meta-analysis was performed using RevMan 4.1.1 software. Results Twenty-Four RCTs comparing MMF (2 g/day or 3 g/day) with AZA for rejection after renal transplantation were identified. The digest system morbidity of MMF group was higher than that of AZA group. The incidence of vomiting, bellyache and diarrhea of MMF 3 g/day group was statistical by higher than that of AZA group (P＜0.05). The cytom egalovirus (CMV) infection morbidity of MMF 3 g/day group during 6 months, 1 year and 2 years follow-up was higher than AZA group with statistical difference, but for MMF 2 g/day group, this difference was only seen during 1 year follow-up. Leukopenia incidence of MMF 3g/day group was higher than AZA group with statistical difference, but this difference was not seen in MMF 2 g/day group. Thrombocytopenia incidence of MMF 3 g/day group was lower than AZA group with statistical difference. For skin carcinoma morbidity, no statistical difference was found among MMF 3 g/day, MMF 2 g/day and AZA groups. Conclusions Compared with AZA, MMF represents higher digest system side-effects incidence, higher morbidity of leucopenia and CMV infection and lower incidence of thrombocytopenia. The dose-response relationship of adverse drug reaction is found.
Objective To evaluate factors such as renal injury grade （Sargent Method）, blunt or penetrative renal injury, injury severity score（ISS）, and shock influencing the need for operation or nephrectomy, and predictive of mortality in renal injury. Methods A well~tesigned questionnaire was used to collect medical records retrospectively. Two hundred and twenty-one cases of renal injury in West China Hospital from 1998 to 2002 were included, logistic regression analysis was used for multi-factors analysis. Results The average age of the 221 cases was 31.6, with 191 males （86.4%） and 30 females （13.6% ）, 175 blunt injuries （79.2%） and 46 penetrative injuries （20.8%）, and 101 concomitant injuries （45.7%）. Six cases died of renal injury （2.7%）. The results of logistic regression showed that the need of operation was related to injury grade, Type of renal injury, and shock significantly. ORs （odd ratios） were 5. 965 with 95% CI 2. 767 to 12. 859, 4. 667 with 95% CI 1. 725 to 12. 628, and 2. 547 with 95% CI 1. 684 to 3. 936 respectively. The need of nephrectomy was significantly related to injury grade with OR 11. 550 and 95% CI 4. 253 to 31. 366. The death was significantly related to ISS with OR 1. 263 and 95% CI 1. 082 to 1. 411. Conclusions The results of our data suggest the need of operation depends on injury grade, blunt or penetrative renal injury, and shock. The need of nephrectomy depends on injury grade. The death is related to ISS.
Objective To systematically review the prognostic and clinicopathological value of plasma fibrinogen in renal cell carcinoma (RCC). Methods An electronic search of the PubMed, EMbase, The Cochrane Library (Issue 5, 2016), CNKI, CBM and WanFang Data databases was performed to collect cohort studies about the prognostic value of plasma fibrinogen in RCC from inception to May 2016. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then meta-analysis was performed by using RevMan 5.3 software. Results A total of 3 744 RCC patients from 7 cohort studies were included. The results of meta-analysis showed that the lower plasma fibrinogen expression group was superior to the higher expression group in overall survival (HR=2.13, 95%CI 1.74 to 2.61,P<0.00 001) and cancer-specific survival (HR=3.12, 95%CI 2.19 to 4.44,P<0.00 001). Subgroup analysis showed that plasma fibrinogen expression was higher in stage Ⅲ to Ⅳ than stage ⅠtoⅡ (OR=0.27, 95%CI 0.13 to 0.55,P=0.000 3) and was higher in Fuhrman grading G3+G4 than grading G1+G2 (OR=0.49, 95%CI 0.40 to 0.59,P<0.000 01). However, the level of plasma fibrinogen was not found to be associated with gender (OR=0.85, 95%CI 0.69 to 1.05,P=0.14). Conclusion Current evidence shows plasma fibrinogen expression is associated with the prognostic and clinicopathological value of RCC. Due to limited quantity and quality of included studies, the above conclusions are still needed to be verified by more high quality studies.
ObjectivesTo systematically review the efficacy and safety of laparoscopic pyelolithotomy (LP) versus percutaneous nephrolithotomy (PNL) in treating large (>2 cm) renal pelvic calculi.MethodsDatabases including PubMed, EMbase, Web of Science, The Cochrane Library, CBM, CNKI and WanFang Data were searched for relevant randomized controlled trials (RCTs) comparing LP with PNL for the treatment of large renal pelvic calculi from inception to September 23th, 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of eligible studies. Meta-analysis was then performed by using RevMan 5.2 software.ResultsFive RCTs with 447 patients were included. The results of meta-analysis showed that: compared with PNL group, LP group provided a significantly higher stone-free rate (RR=1.07, 95%CI 1.01 to 1.13, P=0.01), lower auxiliary procedure rate (RR=0.36, 95%CI 0.13 to 1.01, P=0.05), less hemoglobin decrease (MD=–0.83, 95%CI –1.05 to –0.61, P<0.000 01) and lower postoperative fever rate (RR=0.36, 95%CI 0.18 to 0.72,P=0.004). However, no significant differences were detected in conversion rate (RR=0.76, 95%CI 0.19 to 3.07, P=0.70), blood transfusion rate (RR=0.40, 95%CI 0.14, to 1.12, P=0.08), postoperative leakage rate (RR=1.87, 95%CI 0.67 to 5.21, P=0.23), operative time (MD=10.49, 95%CI –17.14 to 38.13, P=0.46) and hospital stay (MD=0.53, 95%CI –0.22 to 1.28, P=0.17).ConclusionsLP is superior to PNL with regard to stone-free rate, auxiliary procedure rate, hemoglobin decrease and postoperative fever rate. Due to limited quality and quantity of included studies, more high quality studies are required to verify above conclusions.
Rheumatoid arthritis (RA) is one of the most common chronic inflammatory diseases. It mainly involves joints, as well as extra-articular organs. The extra-articular manifestations (EAM) are more common in patients with severe active disease, and the mortality of RA patients with EAM is 2.5 times of RA patients without EAM. Renal damage is rare in EAM, which mainly includes renal damage associated with RA itself, renal amyloidosis, and drug-induced secondary renal damage. In recent years, researches on RA renal damage have gradually increased, and mainly focused on therapy and prognosis. The recent research progress of RA renal damage are summarized in this review.
ObjectiveTo investigate the decision of combined liver and kidney transplantation (CLKT) after renal transplantation, provide surgical therapeutic experience for those patients with liver and renal insufficiencies and hepatorenal syndrome and summarize the risk factors, demerits and merits, and operative indications of CLKT. MethodsThe data of three successful CLKT cases of our centre from Feb. 2014 to Jan 2015 were retrospectively analyzed, and these three patients had kidney transplantation before. We also reviewed the latest associated literatures. ResultsThree patients got successful operations of CLKT and had very good recovery of renal function several days ofter operaton. Two of them discharged a few weeks after surgery, and one of these two patients got severe pulmonary infection of fungus two month after CLKT but recovered under proper therapy finally. The third patient died of severe mixed infection one month after CLKT. ConclusionsThe surgical techniques and rejection are not the main impact factor to the prognosis of CLKT after renal transplantation. Infection is the biggest trouble to which we should pay most of our attention. We should decide whether to do synchronous or nonsynchronous CLKT according to the situation before surgery. Moreover, the systematic therapy administration after CLKT is very necessary for the patients' long-term survival.
ObjectiveTo investigate the anticoagulant drug treatment decision for patients with renal contusion and acute pulmonary embolism, and to enhance the level of treatment for this disease. MethodsA retrospective analysis of the clinical data of a patient with renal contusion and acute pulmonary embolism treated at the West China Hospital of Sichuan University, along with a relevant literature review. Databases including PubMed, Ovid Medline, Embase, VIP, Wanfang and Chinese National Knowledge infrastructure were searched using the keywords as “Pulmonary embolism” AND “Hemorrhage”from January 1983 to December 2023. ResultThe patient was a 21-year-old male who presented with right kidney contusion for 5 days and dyspnea for 1 day. The abdominal CT scan revealed a ruptured right kidney accompanied by hemorrhage and hematoma in the surrounding tissue. Abdomen ultrasound: a low echogenic area measuring approximately 10.6 cm×2.8 cm is noted around the right kidney. The CT pulmonary angiography (CTPA) demonstrated filling defects at the bifurcation of the pulmonary trunk, as well as within the upper and lower lobes of both lungs and their respective branches. The blood gas analysis of patient indicated (face mask oxygen therapy at 10 L/min, oxygenation index of 120): pH 7.456, PCO2 24.9 mm Hg, PO2 73.2 mm Hg. His myocardial markers were Myoglobin: 79.21 ng/ml, Troponin T: 58.7 ng/L, BNP: 2062 ng/L. The patient was diagnosed with renal contusion and pulmonary embolism, and was treated with subcutaneous heparin（initial dose is given as an 80 IU/kg intravenous bolus, followed by a continuous infusion of 12-18 IU/kg/h） and low-molecular-weight heparin at a dose of 0.8 ml every 12 hours one after another for anticoagulation, along with symptomatic treatment. Following the intervention, the patient's respiratory distress showed significant improvement, and subsequent arterial blood gas analysis indicated enhanced oxygenation. Then, the anticoagulant medication was adjusted to oral rivaroxaban anticoagulation for 6 months, follow-up CTPA scan revealed complete resolution of the pulmonary embolism and the abdominal CT scan indicated a reduction in the extent of patchy low-density shadows surrounding the right kidney, leading to the discontinuation of anticoagulation therapy. After searching the above-mentioned databases, total of 26 articles were identified that reported on 30 patients diagnosed with high-risk bleeding and acute pulmonary embolism; among these, 3 patients succumbed while 27 exhibited clinical improvement. ConclusionsPatients with renal contusion and acute pulmonary embolism can be safely and effectively treated with low-dose heparin anticoagulation under close monitoring. High-risk bleeding patients with acute pulmonary embolism present a significant challenge in clinical practice. After weighing the risks of bleeding disorders and the adverse outcomes of pulmonary embolism, it is necessary to find the optimal balance between anticoagulation and bleeding. Consequently, the formulation of personalized treatment strategies in accordance with established guidelines can enhance patient outcomes.
Objectives To analyze the labeling of drug items for patients with renal insufficiency in our hospital so as to provide reference for rational use of drugs. Methods The drug instructions used in No.1 Hospital of Jilin University in 2017 were collected. According to the classification of pharmacology, the instructions of the top 9 drugs system were selected. The annotation of drug items for patients with renal insufficiency in these pharmaceutical instructions was analyzed. Results A total of 812 drug instructions were included, in which 72.17% did not mark drug instruction for renal insufficiency patients. According to the administration system, the highest unlabeled rate were digestive system drugs; according to the method of administration, the highest unlabeled rate was external preparation of drugs, accounting for 83.33%; according to production enterprises, the highest unlabeled rate were domestic drugs, accounting for 75.55%. There were only 23.40% of the tagging items having guidance of medication, and some with a certain degree of confusion in the annotation. Conclusion The unlabelling situation of drug instructions for renal insufficiency patients is very serious. It should arouse the attention of pharmaceutical manufacturers and the pharmaceutical supervisory department is suggested to strengthen the supervision of drug instructions and regulate the contents of drug labeling in drug instructions, so as to guide the rational use of drugs in clinical practice.
