Objective To investigate the feasibility and clinical experience of kidney transplantation from donors with Marfan syndrome (MFS). Methods Clinical data of 2 recipients undergoing kidney transplantation from the same MFS patient were retrospectively analyzed and literature review of 2 cases was conducted. Characteristics and clinical diagnosis and treatment of kidney transplantation from MFS patients were summarized. Results The Remuzzi scores of the left and right donor kidneys of the MFS patient during time-zero biopsy were 1 and 2. No significant difference was observed in the renal arteriole wall compared with other donors of brain death and cardiac death. Two recipients who received kidney transplantation from the MFS patient suffered from postoperative delayed graft function. After short-term hemodialysis, the graft function of the recipients received the left and right kidney began to gradually recover at postoperative 10 d and 20 d. After discharge, serum creatinine level of the recipient received the left kidney was ranged from 80 to 90 μmol/L, whereas that of the recipient received the right kidney kept declining, and the lowest serum creatinine level was 232 μmol/L before the submission date (at postoperative 43 d). Through literature review, two cases successfully undergoing kidney transplantation from the same MFS donor were reported. Both two recipients experienced delayed graft function, and then renal function was restored to normal. Until the publication date, 1 recipient has survived for 6 years, and the other recipient died of de novo cerebrovascular disease at postoperative 2 years. Conclusions MFS patients may serve as an acceptable source of kidney donors. However, the willingness and general conditions of the recipients should be carefully evaluated before kidney transplantation. Intraoperatively, potential risk of tear of renal arterial media should be properly treated. Extensive attention should be paid to the incidence of postoperative complications.

Ureteral stricture, urine leakage and other urinary complications are likely to occur after kidney transplantation, which severely affect the function of renal allograft and even lead to renal allograft loss. Ureteral stent plays a critical role in kidney transplantation, which could promote the urine flow from kidney to bladder after kidney transplantation, lower the pressure within the ureter and reduce the risk of early urinary complications. However, it may also cause urinary tract infection, stent-related complications and BK virus infection, etc. Therefore, clinicians should flexibly grasp the indications for ureteral stent removal. In this article, the application, potential adverse reactions and the timing of removal of ureteral stent in the field of kidney transplantation were reviewed, aiming to provide reference for clinical decision-making related to ureteral stent after kidney transplantation.

Objective: To compare the curative effect of three different surgical methods: peritoneal varicocele ligation, peritoneal single-port laparoscopy and microscopy on varicocele. Methods: Retrospective analysis of the case data of 150 patients with varicocele treated in the Affiliated Hospital of Xuzhou Medical University from September 2016 to September 2018. The average age was 24.5 years, and the age range was 22-30 years. The patients were divided into three groups according to different surgical methods: open group, laparoscopy group and microscope group, with 50 cases in each group. Patients in the open group were treated with retroperitoneal spermatic cord ligation. Patients in the laparoscopic group were treated with single-hole laparoscopic laparoscopic surgery. Patients in the microscope group were treated with microscope surgery. Operation time, postoperative hospitalization time, hospitalization cost reserved arteries, surgical complications (such as testicular hydrocele, scrotal edema, epididymitis, testicular atrophy), recurrence, and semen quality improvement were compared between three groups. Measurement data were expressed as mean ± standard deviation(Mean±SD), the two comparisons used the t test, the comparison between the three groups used the analysis of variance, and the comparison between the count data groups using the Chi-square test. Results: The operation time of the patients in the microscope group [(52.52 ± 4.29) min] was longer than that of the open group [(36.60±3.69) min] and the laparoscopic group [(39.54±2.87) min]. The difference between the two groups was statistically significant (P<0.05); but the postoperative hospitalization time and hospitalization cost of patients in the microscope group [(2.16±0.95) d, (5 251 ± 300) yuan] were higher than those in the open group [(3.80±0.78) d, (64 75±415) yuan)]and the laparoscopic group [(3.28±1.01)d, (7 379±273) yuan] . The results of pairwise comparison showed that the difference between the microscope group, the open group and the laparoscopic group was statistically significant (P<0.05). Arterial preservation in the microscope group [47(94.0%)] were compared with the open group [35 (70.0%)], and laparoscopic group [30(60.0%)] had obvious advantages. Pairwise comparison results showed that the comparison between the microscope group and the open group and the laparoscopic group was statistically significant (P<0.05). After follow-up for six months, 2 cases were lost to follow-up in the microscope group, 1 cases were lost to the open group, and 5 case was lost to the unilateral laparoscopic group. 2(4.2%) patients had complications in the microscope group, and 14 (28.6%) patients had complications in the open group; 9 (20.0%) patients had complications in the laparoscopic group, and the total incidence of complications showed a pairwise comparison, the difference between the microscope group, the open group and the laparoscopic group was significant (P<0.05). The recurrence rate in the microscope group was 2.1% (1/48), the recurrence rate in the open group was 18.4% (9/49), and the recurrence rate in the laparoscopic group was 13.3% (6/45); the recurrence rate was compared in pairs, the difference between the microscope group, the open group and the laparoscopic group was significant (P<0.05) . The improvement rate of semen quality in the microscope group was 68.8% (33/48), the open group was 42.9%(21/49), the laparoscopic group was 55.6%(25/45), pairwise comparison results showed that the microscope group compared with the open group and laparoscopy group, the difference were statistically significant (P<0.05). Conclusions Microscopic surgery has less trauma, faster postoperative recovery, shorter operation cost and hospitalization time. Postoperative complications and recurrence, and improved semen quality are all superior to open spermatic vein ligation and single-hole umbilical laparoscopic surgery, it is a safe and effective way to treat varicocele.

Objective:Objective To explore the clinical values of next-generation sequencing (NGS) in bacterial 16S rRNA region and fungal ITS region for diagnosing and treating urinary tract infection (UTI) in renal transplant recipients.Methods:A total of 90 mid-stream clean-catch urine samples were collected from renal transplant recipients who were diagnosed with UTI at Hospital from January 2017 to December 2019. Each sample was equally divided and tested via NGS method and traditional urine culture separately. The results of pathogen test and detection rate were analyzed and compared.Results:And 21/90 sample were considered to be contaminated due to the identification of three or more kinds of microorganisms by culture. And among the remaining 69 samples, 36 (52.17%) cases tested positive by 16S rRNA sequencing, 25 (36.23%) positive by urine bacterial culture; meanwhile, 34(49.28%) tested positive by ITS sequencing and 4(5.80%) positive by urine fungal culture.Conclusions:The detection rate of both bacteria and fungi in NGS microorganism testing is higher than that in traditional urine culture ( P< 0.05). For renal transplant recipients with UTI, NGS microorganism testing is an effective supplement for traditional urine culture. Improving the detection rate and accuracy of etiology may enable an optimization of individualized treatment.

Objective To analyze the incidence and risk factors of de novo malignant tumors in renal transplant recipients. Methods Clinical data of 1 549 renal transplant recipients were retrospectively analyzed, including the basic status, pathological type and incidence rate of patients with de novo malignant tumors after renal transplantation. The survival situation of these patiensts was assessed. And the risk factors of de novo malignant tumors after renal transplantation were identified. Results The incidence rate of de novo malignant tumors in renal transplant recipients was 3.03%(47/1 549). The 47 recipients were (48±12) years old when undergoing renal transplantation, and they were (55±12) years old when diagnosed malignant tumors. The time interval between transplantation and diagnosis was 66 (36, 100) months. Among the de novo malignant tumors, colorectal cancer was the most common, with a cumulative incidence rate (CIR) of 0.58%. The survival time of 47 recipients with de novo malignant tumors after renal transplantation was 59 (2, 135) months, and the 5-year survival rate was 50%. The recipients with the age > 45 years old when undergoing renal transplantation was a risk factor for de novo malignant tumors after renal transplantation (P < 0.05). Conclusions The incidence rate of de novo malignant tumors is relatively high in renal transplant recipients. The recipients with the age > 45 years old when undergoing renal transplantation is a risk factor for de novo malignant tumors.

Objective To investigate the therapeutic methods of hyperpotassemia induced by excessively high blood concentration of tacrolimus (FK506) caused by drug use after renal transplantation. Methods Clinical data of 10 patients diagnosed with hyperpotassemia induced by excessively high blood concentration of FK506 after administration of antifunga l medication following renal transplantation were collected and retrospectively analyzed. Results At 1-2 months after renal transplantation, 10 patients suffered from pulmonary infectiono r pneumonia complicated with pulmonary fungal infection . An appropriate dose of compound sulfamethoxazole, micafungin, cefoperazone sodium-sulbactam sodium and moxifloxacin was administered for antifungal infection. After potassium-lowering therapy, termination of antifungal medication and FK506 dose adjustment (replaced by cyclosporin for certain cases), the serum level of potassium was declined and maintained within normal range for 10 cases. The serum concentration of FK506 was within normal range. No sign of excessively high level of potassium was observed without any potassium-lowering intervention. Conclusions Postoperative administration of drugs is likely to cause excessively high level of FK506 and hyperpotasesmia. Potassium-lowering therapy, termination of drug use and adjustment of immunosuppressive agents should be adopted to avoid the incidence of adverse pharmacologic interaction.

OBJECTIVETo compare the characteristics of urinary tract infection (UTI) between kidney transplant recipients and non-recipient patients.

METHODSForty-nine kidney transplant recipients with UTI (69 episodes) and 401 non-recipient patients with UTI (443 episodes) admitted in Nanfang Hospital from January 2003 to August 2014 were enrolled in the study. The characteristics of UTI were compared between two groups.

RESULTSIn both groups of UTI, female patients comprised a greater proportion (63.3% and 58.6%) and Escherichia coli was the most common pathogen isolated (37.7% and 34.1%). However, the infection rate of Klebsiella pneumonia in recipients was higher than that in non-recipients (11.6% vs 3.2%, P= 0.001), while the infection rate of Candida albicans was lower (1.5% vs 11.3%, P=0.008) than that in non-recipients. Recipients were likely to develop antibiotic resistance and with a higher recurrence rate than non-recipient patients (38.8% vs 16.7%, P<0.001). Compared to non-recipient UTI patients, the symptoms of urinary irritation in recipient UTI patients were more common. There was higher percentage of neutrophil granulocyte (72.65% ± 1.90% vs 68.59% ± 0.73%, P=0.048), lower proportion of lymphocytes (17.73% ± 1.27% vs 21.28% ± 0.61%, P=0.037), and less platelets [(187.64 ± 10.84) × 10(9)/L vs (240.76 ± 5.26) × 10(9)/L, P<0.01] in recipients than in non-recipient UTI patients.

CONCLUSIONThese results indicate that the characteristics of UTI in kidney transplantation recipients and non-recipients patients are different.
