[Combined application of 2 micron microwave resection and laparoscopy in treatment of urinary tumor in patients after renal transplantation].

Objective: To reduce the negative intervention for the transplant kidney and explore the optimal operational method for treating urinary tumor in patients after renal transplantation.

Methods: From March 2006 to March 2013, a total of 12 post renal transplantation patients with renal pelvis tumor/ureter tumor underwent operations. After the general anesthesia, the patient was placed in lithotomy position.

[Clinical analysis of urothelial cancer after renal transplantation].

Objective: To analyze and summarize the risk factors of malignant tumor after renal transplantation.

Methods: We retrospectively analyzed 435 renal recipients who underwent renal transplantation in our institute from May 1991 to March 2011, and found 14 patients developed malignant tumor, of which 12 were from our institute, and the other 2 were referred from other institute. We analyzed the risk factors of those tumors for their incidence, classification, time of final diagnosis, immunity suppression therapy and prognosis.

Treatment of hyperhomocysteinemia and endothelial dysfunction in renal transplant recipients with B vitamins in the Chinese population.

Purpose: We studied the efficacy of B vitamins as a treatment for hyperhomocysteinemia and endothelial dysfunction in renal transplant recipients in the Chinese population.

Materials And Methods: A total of 36 stable renal transplant recipients with hyperhomocysteinemia were randomly assigned to folate treatment (5 mg folic acid per day, 50 mg vitamin B6 per day and 1,000 microg vitamin B12 per day) or to the control group (placebo only) for 6 months. All subjects underwent tests for creatinine, creatinine clearance rate, average blood pressure, total cholesterol, triglyceride and fasting homocysteine.

[Treatment of hyperhomocysteinemia and endothelial dysfunction in renal-transplant recipients with vitamin B].

Objective: To study the effect of vitamin B on treatment of hyperhomocysteinemia and endothelial dysfunction in renal-transplant recipients.

Methods: Thirty-six stable hyperhomocysteinemic renal-transplant recipients were randomly assigned to vitamin treatment (group A, n = 18, folic acid 5 mg/d, vitamin B(6) 50 mg/d, B(12) 1000 microg/d) or controlled group (group B, n = 18) for 6 months. All subjects underwent assessment of levels for creatinine, creatinine clearance, average pressure, total cholesterol, triglyceride and fasting homocysteine.

[Analysis of eleven cases of severe pneumonia in kidney transplant recipients].

Objective: To analyse retrospectively the diagnosis and treatment of severe pneumonia in kidney transplantation recipients.

Methods: Between January 1999 and December 2003, 172 adult patients underwent kidney transplantation at our department. In all severe pneumonia cases, empirical therapy was initiated with aztreonam, erythromycin and ganciclovir.

Electron paramagnetic resonance in monitoring of nitric oxide production after kidney transplantation in rats.

Background: Much research has been focused on ischemia/reperfusion injury (IRI) to the transplanted organs. As a free radical, nitric oxide (NO) plays an important role in IRI. In this study, the production of NO and its functions during IRI were monitored in rat models after allotransplantation of kidney grafts.
