Objective To compare the therapeutic effect of new “One-Stitch” ureterovesical anastomosis to that of the classic Lich-Gregoir method. Methods From January 2002 to December 2004, 445 patients suffering from uremia due to chronic nephritis were treated with renal transplantation. Among them, 121 patients were operated with our new modified ureteroneocystostomy technique (the new One-Stitch group), and 324 patients were operated with Lich-Gregoir technique (the Lich-Gregoir group). In the new One-Stitch group, there were 79 males and 42 females, aged 20-62 years (35.7 years on average). The course of the disease was 2-11 years (2.7 years on average). In the Lich-Gregoir group, there were 211 males and 113 females, aged 19-65 years (33.9 years on average). The disease course was 1-14 years (2.3 years on average). There was no significant difference between the two groups in age, proportion of genders, primary diseases and course of the disease (P gt; 0.05). The operative time, the ureteral compl ications and non-ureteral compl ications were compared between the two groups after the renal transplantation. Results The operative time for the new One-Stitch and Lich-Gregoir techniques was (8.7 ± 1.1) minutes and (22.4 ± 5.1) minutes, indicating the difference was significant (P lt; 0.05). All recipients were followed up for 3-5 years. In the new One-Stitch group, there were 5 patients with leakage of urine, 15 with gross hematuria, 4 with ureteral obstruction and 28 with urinary system infection. Symptomatic vesicoureteral reflux and stone formation were not observed in this group. In the Lich-Gregoir group, there were 17 patients with leakage of urine, 12 with gross hematuria, 13 with ureteral obstruction, 86 with urinary system infection, 6 with symptomatic vesicoureteral reflux and 2 with stones. In the new One-Stitch group, the incidence rate of compl ications of gross hematuria was 12.4%, which was significantly different from 3.7% in the Lich-Gregoir group (P lt; 0.05). The incidence rates of ureteral compl ications in the Lich-Gregoir and the new One-Stitch groups were 19.8% and 15.4%, respectively. The difference was not significant (P gt; 0.05). There was no significant difference between the two groupsin incidence rate of urinary system infection, delayed recovery of kidney function after kidney transplantation and rejectionreaction (P gt; 0.05). Conclusion The new One-Stitch group has no significant difference in ureteral compl ications ompared with the Lich-Gregoir group, and has become a preferential ureterovesical reimplantation technique because of its simple and has convenient operation.
Objective To approach the questions of donation after cardiac death （DCD） and transplantation through analyzing the DCD cases in this hospital. Methods The organs were obtained from 4 DCD from 2010 to 2011 in this hospital， the clinical data of DCD were analyzed retrospectively. Results Seven renal transplantations and 3 liver transplantations were performed. Donor warm ischemic time was 10-40 min. The liver and left kidney of the first DCD donator （Maastricht categoryⅣ） were eliminated through biopsy. One patient exhibited delayed graft function of kidney from the first DCD，the nephrectomy had to be done on day 7 after operation due to renal allograft rupture. Nine patients received 3 livers and 6 kidneys from the other 3 DCD donators （Maastricht categoryⅢ），whose patients were alive with excellent graft function. Conclusions The use of controlled DCD （Maastricht categoryⅢ） might be an effective way to increase the number of organs available for transplantation because that it might obtain satisfactory transplant outcomes and acceptable postoperative complications. The widespread implementation of controlled DCD in China should be encouraged.
ObjectiveTo analyze the clinical outcomes of cardiac surgery in patients after kidney transplantation underwent immunosuppression therapy. Methods Clinical data of 6 patients (including 4 males and 2 females aged from 27 to 66 years) undergoing cardiac surgery after kidney transplantation with immunosuppression between January 2011 and October 2013 in Beijing Anzhen Hospital were retrospectively analyzed. Two patients underwent off pump coronary artery bypass grafting, 3 patients underwent aortic valve replacement and 1 patient underwent mitral valve replacement. The interval between kidney transplantation and cardiac operation was 8.5±1.7 years (range, 6-10 years). ResultsAll the operations were performed successfully without in-hospital death and complications. Operation time was 237.0±93.0 min. Cardiopulmonary bypass (CPB) time was 101.3±16.7 min. Aortic cross-clamping time was 75.6±9.7 min. in-hospital stay was 17±6 d. There was a statistical difference in preoperative and postoperative left ventricle ejection fraction (63.5%±4.5% vs. 56.5%±5.8%, P < 0.05), as well as preoperative and postoperative left ventricular enddiastolic diameter (54.5±8.5 mm vs. 43.7±6.8 mm, P < 0.05), but there was no statistical difference in preoperative and postoperative serum creatinine levels (103.7±15.1μmol/L vs. 106.6±34.7μmol/L, P > 0.05). The mean follow-up time of the 6 patients was 4-15 months. The follow-up rate was 100%. All the patients were in cardiac function NYHA classⅠ-Ⅱ. And the quality of life was improved. ConclusionCardiac operations for kidney transplant recipients undergoing immunosuppressive treatment are effective and safe as long as appropriate perioperative treatment are taken.
ObjectiveTo explore the effect of donation after citizen death (DCD) kidney transplantations performed in Sichuan.MethodsThe data of 97 cases of DCD kidney transplantations performed in West China Hospital of Sichuan University between January 2012 and March 2016 was retrospectively reviewed. The 53 donors were aged from 7 months to 54 years (with a median of 28 years, and lower quartile of 15 years and upper quartile of 45 years), including 40 males and 13 females; the causes of death included craniocerebral trauma in 21 cases, craniocerebral tumor in 12 cases, cerebrovascular accident in 15 cases, hypoxic-ischemic encephalopathy in 4 cases, and hydrocephalus in 1 case. The 97 recipients were aged from 18 to 66 years (with a median of 39 years, and lower quartile of 30 years and upper quartile of 44 years), including 71 males and 26 females. The recipients were classified into C-Ⅰ (n=36) and C-Ⅲ (n=61) according to type of donation. The baseline and perioperative situation of the donors and recipients, and the postoperative kidney function, infection, recipient survival and kidney survival of the recipients were analyzed.ResultsAfter transplantation, none of primary graft nonfunction occurred but delayed graft function (DGF) occurred in 26 cases. There were no significant differences in creatinine level between C-Ⅰ and C-Ⅲ recipients at 1 week [(226.71±187.46) vs. (249.94±249.84) μmol/L, P=0.636], 1 month [(136.32±63.34) vs. (157.37±147.83) μmol/L, P=0.428], 3 months [(110.51±25.26) vs. (115.02±36.60) μmol/L, P=0.527] and 12 months [(103.42±21.57) vs. (104.18±39.36) μmol/L, P=0.911] after transplantation, as well as acute rejection [13.9% vs. 19.7%, P=0.469] and complications at early time after transplantation. There were no significant differences in 1-year recipient survival rate (91.7% vs. 93.4%) and 1-year kidney survival rate (100.0% vs. 91.8%) between C-Ⅰ and C-Ⅲ recipients.ConclusionDCD kidney transplantation has excellent short-term outcomes despite a high incidence of early DGF, and may represent another potential method to safely expand the donor pool.
