We have designed a protocol for ABO-incompatible kidney transplantations based on preoperative plasmapheresis with a tacrolimus/mycophenolate mofetil/methylprednisolone/basiliximab protocol using low-dose rituximab (200 mg/body) instead of splenectomy to prevent antibody-mediated acute rejection. Eight patients successfully received transplants with this protocol. The titers of anti-A and -B antibodies as well as the number of CD20(+) cells were readily maintained at a low level posttransplantation. There were no side effects. All patients have renal transplant function with a follow-up of 1-34 months.

Solitary fibrous tumor (SFT) rarely occurs in the kidneys, and only one reported case of renal SFT has shown distant metastasis. We report the second case of renal SFT exhibiting distant metastasis. A 48-year-old man was referred to our hospital because of a right renal mass. An abdominal CT scan detected a large renal tumor, which was suspected to be a renal cell carcinoma. Right radical nephrectomy was performed, and the tumor was found to measure 28 × 18 × 10 cm. The pathological diagnosis was benign solitary fibrous tumor of the kidney. Eight years after the operation, lung and liver metastases developed. Pulmonary segmentectomy and partial hepatectomy were performed. The pathological diagnoses of these resected tissue specimens were compatible with benign SFT.

Synchronous bilateral urothelial cancer is very rare. We report a 25‐year‐old male kidney recipient with Alport syndrome who developed bilateral synchronous urothelial cancer after transplantation. At the age of 16 this patient was referred to our clinic for a kidney transplantation. A living related donor kidney transplantation was performed with cyclosporin‐based quadruple immunosuppression. He experienced no acute rejection and his graft function was excellent after transplantation. Nine years after transplantation, he complained of asymptomatic gross hematuria and was diagnosed as having a bilateral urothelial cancer in the native upper urinary tracts. A bilateral total nephroureterectomy was undertaken, and the postoperative pathological diagnosis was advanced bilateral urothelial carcinoma. The patient received adjuvant gemcitabine plus cisplatin chemotherapy at a cisplatin dosage reduced by 50%. After 4 years of follow‐up, he is alive with a functioning graft and no evidence of recurrence.

BACKGROUND In kidney transplant recipients, the most widely used method for the reconstruction of the urinary pathway is ureteroneocystostomy, which may be difficult in cases with disused atrophic bladder. In this study, we evaluated kidney transplant recipients who underwent uretero-ureteral end-to-side anastomosis (UUA) in urinary reconstruction due to disused atrophic bladder. METHODS To clarify the effectiveness of this method, we retrospectively reviewed the clinical records of kidney transplant recipients in our hospital. RESULTS A total of 9 recipients with urinary reconstruction using UUA were evaluated. All of these patients had a history of long-term hemodialysis before transplantation, accompanied by complete anuria and small capacity of the bladder. In 4 patients, cranial native ureter was ligated, whereas it was not ligated in the remaining 5 patients. In 2 of 4 patients with cranial ligation, hydronephrosis developed in the native kidney with no further treatment being required. No patients experienced urinary tract complications including hydronephrosis in the graft, urine extravasation, or urinary tract infection in the follow-up period (757.6 ± 491.3 days). Allograft function was maintained well in all patients (serum creatinine level, 1.08 ± 0.23 mg/dL). CONCLUSIONS Although UUA is not a routine method of urinary reconstruction in kidney transplantation, it can be safely performed and should be a surgical option, especially for recipients with disused atrophic bladder. The ligation of cranial native ureter may lead to hydronephrosis of the native kidney, and it is tentatively concluded that UUA without native ureteral ligation is clinically feasible.

Autologous blood transfusion (ABT) is rarely employed in patients with end-stage renal disease (ESRD); these patients are usually anemic. Since 1998, we have attempted ABT for ESRD patients undergoing living-related kidney transplantation. Among 20 patients enrolled in this study the preoperative hemoglobin and hematocrit levels were 10.0 +/- 1.2 mg/dL (range, 8.1-11.7) and 30.0 +/- 3.7% (range, 24.7-34.3), respectively. Blood volume collected on each occasion was 235.7 +/- 57.7 mL (range, 200-400), and the number of blood collections was 2.45 +/- 0.9 (range, 1-4). Total collected volume was 567.5 +/- 157.5 mL (range, 400-800). Symptomatic hypotension was seen in two patients, but vital signs recovered spontaneously. No other problems related to blood collection were observed. Allogeneic transfusion was need in only one patient (5%). ABT was safe and efficacious in ESRD patients scheduled for living-related kidney transplantation.

As the number of patients on hemodialysis increases, there will also be an increase in the number of patients with inadequate superficial veins for the creation of an autogenous arteriovenous fistula (AVF). In those patients, medical devices such as vascular prostheses or tunneled-cuffed catheters are necessary to maintain dialysis access. However, these devices are frequently associated with bacterial infection. We recently encountered a dialysis patient who underwent tunneled-cuffed catheter insertion because of the lack of usable superficial veins for autogenous access, and this patient subsequently developed catheter-related Staphylococcus aureus bacteremia with multiple metastatic infections. Despite immediate removal of the catheter, the infection persisted over an extended period, which was a condition precluding the further use of catheters or other prosthetic materials. To handle this situation, we utilized the deep brachial vein to construct an autogenous AVF. After ligating numerous branches, the vein was anastomosed to the brachial artery and then transposed to the subcutaneous space. The newly constructed autogenous AVF, which successfully kept the patient free from foreign materials, greatly contributed to the relief of persistent infection. Although the brachial vein is rarely used for AVF creation, we suggest that it can serve as an option to create an alternative AVF in a patient with inadequate superficial veins.
