The results of pretransplantation preparation of patients undergoing peritoneal dialysis program before the kidney transplantation at our clinic have been presented. Residual kidney function, and bladder function, respectively, as well as the incidence of the hepatotropic viruses B and C infections and cytotoxic antibodies percentage following blood transfusion have been particularly analyzed. Obtained results have been correlated with those found in 40 patients on hemodialysis and to whom kidneys were transplanted at our clinic. Satisfactory bladder function, the absence of urologic posttransplantation complications, non-existence of hepatotropic viral infections and cytotoxic antibodies resulted in an introduction of a new strategy based on the peritoneal dialysis as the first method of the dialysis treatment prior to kidney transplantation. 相似文献

The aim was to present a four-year experience in living related kidney transplantation. A total of 43 patients (9 females and 34 males) were enrolled in this study. The standard triple immunosuppressive therapy (steroids, azathioprine and cyclosporine) was administered in 19 (44.1%) patients, and in 20 (46.5%) mycophenolate mophetil in daily dose of 2 g instead of azathioprine. In 5 (14.2%) patients with high immunological risk and delayed graft function was administered antithymocite globulin in duration of 7-14 days, prophylactically. In 3 (6.97%) patients graft loss was caused by vascular complications and in 1 (2.32%) by infection as the complication. During the first post-transplantation year acute rejection was noticed in 8 (34.7%) patients and in 3 (37.5%) it was steroid resistant. The graft loss was never caused by acute rejection. Six-months graft survival was noticed in 91.1% patients and one-year graft survival in 88.4% patients. One-year patient survival was 100%. Short term results in living related kidney transplantation are excellent and nowadays, due to improvement in immunosuppressive therapy, the success in this type of kidney transplantation is mainly limited by surgical and infective complications. 相似文献

Acute impairment of renal function caused by cyclosporin A can be hard to differentiate from acute rejection. Therefore, kidney function after cadaveric allograft transplantation was repeatedly determined by renography in 42 patients receiving either high dose cyclosporin A (32 patients) or azathioprine and prednisone (10 patients) until a graft biopsy showed either acute rejection or no rejection within the first 5 postoperative weeks. The graft function as judged from the renograms was significantly poorer when cyclosporin A was used than when azathioprine and prednisone were the immunosuppressants. In the azathioprine and prednisone group a biopsy showing acute rejection was always preceded by a deterioration in the renogram. In cyclosporin A treated patients a graft biopsy following an early deterioration in the renogram showed acute rejection in only 56% of the biopsies. It was not possible to identify a time course or a function level of the renogram that could predict rejection in these patients. It is concluded that graft biopsies should be used liberally to diagnose rejection during cyclosporin A treatment if surgical complications after transplantation have been ruled out. Radionuclide studies may offer an invaluable aid in determining a nonnephrotoxic initial dose of the drug. 相似文献

Changes in transplanted kidney volume measured by ultrasound 总被引:1,自引:0,他引:1
A simple ultrasonic method was used for measuring transplanted kidney volume in 29 patients. Five of these patients developed diabetes mellitus and six women became pregnant following transplantation. Serial measurements were performed over periods of 6-12 months after transplantation. The kidney volume became stable 6 months after transplantation and this volume correlated positively with the renal function. Renal hypertrophy was noted in those transplant patients who developed diabetes mellitus following transplantation and this hypertrophy was associated with improvement in graft function. Transplant volume also rose in acute rejection and returned to normal after appropriate treatment. During pregnancy following transplantation, the transplant volume increased early in pregnancy to return to normal before delivery. This volume increase was also associated with graft function improvement. 相似文献

PURPOSE: In the past decades the indications for local graft irradiation (LGI) in acute renal transplant rejection have been limited and considered unfavorably. Despite major advantages in maintenance immunosuppression and management of acute allograft rejection a minority of patients remains with drug resistant transplant rejection. This subgroup of patients may benefit from LGI. PATIENTS AND METHODS: Between 1979 and 1990, eight patients with biopsy-proven acute renal allograft rejection and failure of all other immunosuppressive measures (corticosteroids, ATG, ALG or OKT3) were treated with LGI. Retrospective analysis was conducted for this control group. Radiotherapy was performed with Co-60 up to a median total dose of 6.0 Gy (single doses: 1.5-2.0 Gy). Six of eight patients were dialysis dependent prior to irradiation. In addition a literature review was performed including most important textbooks, electronic databases (Medline, Embase, Science Citations Index), and the internet. RESULTS: Two of eight patients experienced a clinical reversal of rejection and an improvement of renal function: serum creatinine decreased significantly. One patient remained free of dialysis with a functioning graft, the other had a recurrent rejection 2 months later and became dialysis dependent. The literature review showed, that adjuvant LGI has no advantage over conventional immunosuppression. However, in case of a drug refractory allograft rejection LGI restores long-term stable organ function in 13-60% of cases. CONCLUSION: The value of LGI of organ transplants, like renal allografts, is still not clearly defined. As a rescue measure in drug refractory allograft rejection special patients may clinically benefit, when a transplant nephrectomy can be avoided. Further prospective clinical trials are needed for a better assessment of LGI in organ transplantation. 相似文献

At the transplantation center of Rigshospitalet , Copenhagen, retrograde pyelography is routinely performed via a ureteral catheter inserted during the operation. Ninety-nine retrograde pyelographies performed within the first days after renal transplantation were reviewed. The clinical records of 30 additional patients who had not been subjected to pyelography were also reviewed. Intrarenal backflow (IRB) was seen in 14 per cent of the pyelograms. Upper urinary tract obstruction (29 cases) was observed with equal frequency in the groups with and without IRB. No relationship was observed between IRB and length of warm and cold ischemia of the graft, urinary tract infection (UTI), donor kidney age and graft function on the day of retrograde pyelography. In 40 per cent of the grafts with irreversible rejection within 60 days after transplantation IRB was found at pyelography in the first days after operation. IRB occurred in only 5 per cent of the kidneys with good long term function. Most frequently IRB was localized to the upper pole but was also observed in other parts of the kidney. IRB may be an early radiographic sign of an impending and irreversible graft rejection. There was no evidence that retrograde pyelography increased the frequency of UTI or the number of episodes of irreversible rejection. 相似文献

In order to evaluate renal ischemic damage in transplanted kidneys, renal scintigraphy with 99mTc-methylene disphosphonate was performed in 30 kidney grafts within 36 h after transplantation. The renal uptake was monitored for 100 s at 10-min intervals during 90 min following injection. Seventeen patients had an average uptake of radioactivity in the kidney on the 60-, 70-, 80-, and 90-min scintigrams expressed as a percentage of the activity present on the 10-min scintigram of 150% or less (low) and 13 patients had an average uptake of radioactivity of above 150% (high). There was no relationship between the average uptake of radioactivity and warm and cold ischemia times (or the combined value: corrected ischemia), maximal function, reversible rejection, and ureteral obstruction. A significant correlation was found between the average uptake of radioactivity in the kidney and onset of function. Seventy-six per cent of the grafts with a low average uptake of radioactivity had an onset of function on or before day 10 after operation (early) whereas only 15% of the kidneys with a high average uptake of radioactivity had an early onset of function. Twelve per cent of the patients with a low average uptake of radioactivity in the kidneys had their grafts removed for various reasons within 2 months after transplantation, whereas 54% with a high average uptake of radioactivity had their grafts removed. It is concluded that 99mTc-methylene diphosphonate scintigraphy may be useful in the prognostic assessment of graft onset of function and of graft survival.This study was approved by the Committee on Investigations/ Activities involving Human Subjects for the Copenhagen County, Approval no. 164 相似文献

Patients with end-stage kidney disease, particularly those treated with dialysis, have an increased risk of renal cell carcinoma. Renal cell carcinoma may also develop in the native kidneys of renal transplant recipients with good graft function many years after transplantation. Recent studies suggest that the incidence of renal carcinoma among dialysis patients is 3-6 times greater than in the general population. However, annual imaging of the native kidneys of all dialysis patients is not justified because it has not been shown to have a significant effect on patient outcome. Screening may, however, be useful in selected patients with good general medical conditions and who have known risk factors for renal carcinoma. 相似文献

In a previous survey we revealed uncertainty among responders about (a) whether or not to perform hemodialysis in patients
with severely reduced renal function who had received contrast medium; and (b) when to perform hemodialysis in patients on
regular treatment with hemodialysis or continuous ambulatory dialysis who received contrast medium. Therefore, the Contrast
Media Safety Committee of The European Society of Urogenital Radiology decided to review the literature and to issue guidelines.
The committee performed a Medline search. Based on this, a report and guidelines were prepared. The report was discussed at
the Ninth European Symposium on Urogenital Radiology in Genoa, Italy. Hemodialysis and peritoneal dialysis safely remove both
iodinated and gadolinium-based contrast media. The effectiveness of hemodialysis depends on many factors including blood and
dialysate flow rate, permeability of dialysis membrane, duration of hemodialysis and molecular size, protein binding, hydrophilicity,
and electrical charge of the contrast medium. Generally, several hemodialysis sessions are needed to removal all contrast
medium, whereas it takes 3 weeks for continuous ambulatory dialysis to remove the agent completely. There is no need to schedule
the dialysis in relation to the injection of iodinated or MR contrast media or the injection of contrast agent in relation
to the dialysis program. Hemodialysis does not protect poorly functioning kidneys against contrast-medium-induced nephrotoxicity.
Simple guidelines are given.

Screening chronic hemodialysis patients (CHD) for acquired cystic disease of the kidneys (ACDK) and its complications (hemorrhage and neoplasm) has become accepted management. We evaluated patients on CHD as well as patients on chronic peritoneal dialysis (CPD) for ACDK. The kidneys of 80 chronic dialysis patients were examined by CT and real time sonography. Forty-four were hemodialysis and 36 were peritoneal dialysis patients. ACDK was found in more than 90% of both CHD and CPD patients who had been dialyzed longer than three years. Bilateral renal carcinoma was detected in one hemodialysis patient. Our results show that chronic peritoneal dialysis patients are also at risk for ACDK and its associated complications. A similar natural history for the development of ACDK in both forms of dialysis suggests that the same screening precautions should be instituted for chronic peritoneal dialysis patients. 相似文献

BACKGROUND: Acute rejection of allograft is one of the most serious complications of renal transplantation that requires fast and precise diagnostic approach. In this paper our experience in cytologic urinalysis as a diagnostic method of the acute renal allograft rejection was reviewed. METHODS: The study group included 20 of 56 patients with transplanted kidneys who were assumed for the acute allograft rejection according to allograft dysfunction and/or urine cytology findings. Histological findings confirmed allograft rejection in 4 patients. Urine sediment obtained in cytocentrifuge was air-dried and stained with May-Grunwald-Giemsa. Acute allograft rejection was suspected if in 10 fields under high magnification 15 or more lymphocytes with renal tubular cells were found. RESULTS: Acute transplant rejection occurred in 32.1% patients. In 15 patients clinical findings of the acute renal allograft rejection corresponded with cytological and histological findings (in the cases in which it was performed). Three patients with clinical signs of the acute allograft rejection were without cytological confirmation, and in 2 patients cytological findings pointed to the acute rejection, but allograft dysfunction was of different etiology (acute tubular necrosis, cyclosporine nephrotoxicity). In patients with clinical, cytological and histological findings of the acute allograft rejection urine finding consisted of 58% lymphocytes, 34% neutrophilic leucocytes and 8% monocytes/macrophages on the average. The accuracy of cytologic urinalysis related to clinical and histological finding was 75%. CONCLUSION: Urine cytology as the reliable, noninvasive, fast and simple method is appropriate as the a first diagnostic line of renal allograft dysfunction, as well as for monitoring of the graft function. 相似文献

PURPOSE: To review the author's early experience with stent grafts to repair hemodialysis graft-related pseudoaneurysms. MATERIALS AND METHODS: Eleven patients had undergone insertion of a stent graft to repair a pseudoaneurysm arising from a PTFE hemodialysis graft. The study group consists of seven women and four men with a mean age of 50.7 years. The primary indications for stent graft placement were: rapid enlargement of a pseudoaneurysm in four patients, difficulty with cannulating the graft in two patients, high risk of acute rupture in three patients, persistent bleeding from the pseudoaneurysm in one patient, and one was incidentally discovered during diagnostic fistulography. In 10 of the 11 patients, the pseudoaneurysm arose from the arterial limb of a loop-configuration graft. A stent graft was successfully deployed in all patients. The radiological and surgical records were reviewed. RESULTS: The Viabahn endoprosthesis was successfully inserted and deployed in all 11 patients. Six patients underwent subsequent interventions, which ended primary patency at 39 days, 40 days, 63 days, 104 days, 120 days, and 327 days after insertion of the stent graft. However, no additional interventions have been performed in five patients and primary patency continues. In these five patients the interval of continuing primary patency is 55 days, 92 days, 103 days, 139 days, and 196 days. In this small group of patients the primary patency rate is 71% at 3 months and 20% at 6 months. DISCUSSION: Early experience has demonstrated that a stent graft can successfully exclude a pseudoaneurysm from a hemodialysis graft and may prevent further enlargement and decrease the likelihood of rupture. However, in two of these 11 patients, the large pseudoaneurysm remained problematic and required subsequent surgical repair. 相似文献
