Balloon-assisted creation and maturation of an arteriovenous fistula in a patient with small-caliber vasculature.

The major problem associated with the creation of an arteriovenous fistula (AVF), which is the optimal form of vascular access for hemodialysis, is the fact that fistulas do not necessarily mature into a usable vascular access, requiring subsequent revision and construction of another access. The caliber of the vessels used for fistula creation is a pivotal factor predicting the presumable maturation of the constructed fistula, and veins less than 2.5 mm in diameter have poor outcomes.

Mild rhabdomyolysis after renal transplantation.

We present a kidney transplantation patient who developed rhabdomyolysis. The patient was initially immunosuppressed with tacrolimus, mycophenolate mofetil, steroids, and chimeric CD25 monoclonal antibody. He complained of severe precordial and appendicular pain on 25th day after the operation.

Immunological status in three patients, thirty years after living related renal transplantation: antibody production in long-term survivors.

There have been few studies of the immune status of long-term follow-up patients after living-donor kidney transplantation. We investigated the immune status from the immunologic and pathologic standpoint of three long surviving recipients who had received renal grafts more than 30 years earlier. Anti-HLA antibodies that had not been present before transplantation were detected in one recipient with three HLA mismatches.

Early and late histopathological changes in renal allografts procured by laparoscopic donor nephrectomy.

Introduction: Subcapsular cortical damage (SCCD) is a characteristic pathological change, which is seen in renal allograft biopsy specimen obtained immediately after laparoscopic donor nephrectomy (LDN). In this study we evaluated the early and late histopathological effect of SCCD examining renal allograft biopsy specimens obtained after kidney transplantation.

Materials And Methods: Laparoscopic donor nephrectomy was performed on 250 donors between July 2000 and September 2004 in our institution.

Long-term results of living kidney transplantation from HLA-identical sibling donors under calcineurin inhibitor immunosuppression.

Background: Recently, it has been revealed that alloantigen-independent causes are important factors for late graft loss in kidney transplantation. We compared the results of living kidney transplantation from HLA-identical siblings with those from HLA-non-identical siblings to analyse the impact of alloantigen-independent factors on long-term graft survival.

Methods: Two hundred and sixty-six recipients who were grafted from their siblings between 1983 and 2002 were subdivided into those transplanted from HLA-identical donors (n=86) and those from HLA-non-identical donors (n=180).

Differences in humoral immunity between a non-rejection group and a rejection group after ABO-incompatible renal transplantation.

Background: Renal transplantation across the blood barrier is a unique model for investigating the humoral response to different carbohydrate antigens. However, in such a renal transplantation, the characteristics of B cells as well as of the antibodies produced by B cells are less well defined.

Methods: In the present study we investigated B cell subsets (i.

Lack of correlation between results of ABO-incompatible living kidney transplantation and anti-ABO blood type antibody titers under our current immunosuppression.

In this study, we examined the impact of preoperative anti-A/B antibody titers on the results of ABO-incompatible living kidney transplantation (LKT). In all, 167 recipients underwent ABO-incompatible LKT at our institution between 1989 and 2002. These patients were subdivided into those transplanted under cyclosporine with azathioprine or mizoribine (Group 1, n=78) and those transplanted under tacrolimus or mycophenolate mofetil (Group 2, n=89).

The mechanism responsible for accommodation after living-related kidney transplantations across the blood barrier.

The mechanism responsible for accommodation in renal transplantations across the blood barrier remains unclear. We recently encountered two patients with accommodated status after living-related kidney transplantations across the blood barrier. Both developed elevations of anti-blood-group antibodies to titers over 128x after transplantation, despite excellent renal function.

Retroperitoneoscopic live donor nephrectomy (RPLDN): establishment and initial experience of RPLDN at a single center.

We tried to establish the technique of retroperitoneoscopic live donor nephrectomy (RPLDN). Between July 2001 and March 2004, 135 renal transplant donors underwent RPLDN. Low (average: 7 mmHg) CO2 gas pressure was employed during the procedure.

Evaluation of flow cytometric panel reactive antibody in renal transplant recipients - examination of 238 cases of renal transplantation.

In Japan, the complement-dependent cytotoxicity (CDC-crossmatch) test and the anti-donor antibody flow cytometric assay (FCXM) are used to evaluate presensitization among transplantation candidates. We introduced the flow cytometric panel reactive antibody method (FlowPRA) at our institution, and in this paper, we compared the results of FCXM and FlowPRA. Sera of a total of 238 patients receiving the first graft were analyzed by FlowPRA retrospectively.
