In order to avoid cyclosporine (CsA) nephrotoxicity and rejection, especially during the early posttransplant periods, different immunosuppression regimens have been adopted. A prospective trial was conducted to evaluate the benefits of initially low CsA doses associated with antilymphoblast globulin and steroids in the first days after transplant, in comparison with higher doses of CsA and steroids. Between 1/86 and 1/88, two groups of first-cadaver renal transplant recipients were documented based on the immunosuppression regimen used. In group A (n = 50), oral CsA was started at 8 mg/kg/day and subsequent doses adjusted to maintain CsA whole-blood levels between 300 and 600 ng/ml. Horse ALG at 10 mg/kg was given the day after transplant and on alternate days to a maximum of 6 doses. After 3 doses, ALG was stopped if CsA blood levels were equal to or greater than 400 ng/ml. ALG dosage modifications were made in order to maintain peripheral CD3+ cells between 10 and 20%. Prednisone was given at 0.25 mg/kg/day. In group B (n = 50), oral CsA was started at 15 mg/kg/day. The CsA whole-blood levels were maintained between 300 and 800 ng/ml. Prednisone was administered at 0.5 mg/kg/day. The incidence of postransplant renal failure was the same in both groups (16%), but the duration of oliguria was lower in group A than in group B (3.3 +/- 2 vs. 16.2 +/- 10.7 days, P less than 0.05), as well as the incidence of acute rejection during the first 3 months (18% vs. 40%, P = 0.01. The cumulative doses of CsA and steroids were significantly lower in group A than in group B. Mean serum creatinine at 6 and 12 months remained similar in both groups. There was no difference between the 2 groups in the incidence of infection. There was no mortality in either group. The actuarial graft survival was significantly higher in group A than in group B at one (100% vs. 94%), two (97% vs. 87%), and three years (89% vs. 73%), respectively (P = 0.041). In summary, the triple regimen using simultaneously low-dose CsA, ALG, and steroids minimizes early graft dysfunction, provides efficient immunosuppression without severe infections, and gives good long-term patient and graft survival.

Urological complications constitute significant problem following renal transplantation. Incidence ranges from 4 to 14% in graft recipients. The most important aspects concerning these complications are early diagnosis and prompt treatment, any delay in diagnosis and management may lead to deterioration of renal graft function or graft loss. The following case report discusses management of hydronephrosis in renal graft caused by ureter stenosis due to scarring and fibrosis of its distal end after remote kidney transplantation. The patient was a 33-year-old woman with previous history of end stage renal failure in the course of chronic glomerulonephritis. A triple drug immunosuppressive regimen consisting of Azathioprine (AZT), Cyclosporine A and Encorton (AZT + CsA + Encorton) was administered during a period of three years after kidney transplantation. At this time AZT administration was discontinued due to chronic viral hepatitis type B. Episodes of expansion sensation (discomfort) and graft pain were reported by the patient which after 3 days were followed by a period of oliguria and then anuria. The patient was admitted to the Department of Nephrology CMUJ, where ultrasound imaging revealed graft hydronephrosis. In the presence of such clinical and biochemical indications due to acute graft failure, one hemodialysis session, was performed. The patient was transferred to the Urological Department CMUJ where ureter exploration was attempted, but was unsuccessful. Subsequently percutaneous nephrostomy was performed which lead to immediate diuresis. Next, distal ureter stenosis (located by the urinary bladder) was surgically removed and reimplantation of the ureter was carried out. Due to early diagnosis and surgical reconstruction of the transplanted ureter, renal graft function returned to normal requiring only one hemo-dialysis session.
