    Abstract:
    In the present study we report the renal pathological findings from autopsy material along with relevant clinical data on 21 spinal cord injury patients with end-stage renal disease (SCI-ESRD) treated with maintenance haemodialysis. These data are compared with the relevant clinical and post-mortem findings on 43 ambulatory dialysis patients who expired during the same time period. The SCI-ESRD patients exhibited markedly different clinical and renal histopathological data when compared to the ambulatory--ESRD group. Chronic pyelonephritis and amyloidosis dominated the findings and were the major causes of renal insufficiency. Acute pyelonephritis, papillary necrosis, calculous disease, pyonephrosis and perinephric abscess formation were also more frequently present in the SCI-ESRD patients. Hypertension and nephrosclerosis, which were common findings in the ambulatory--ESRD patients were comparatively rare in the SCI-ESRD patients. In addition, the incidence of acquired cystic disease (ACD) was considerably less in the SCI-ESRD group. Although the reasons for these findings are not entirely clear several possible explanations are given. Infection with gram negative sepsis was the predominant cause of death in the SCI-ESRD patients, while death secondary to cardiovascular disease predominated in the ambulatory-ESRD group. Furthermore, the urinary tract and infected decubitus ulcers were determined to be the major source for sepsis in the SCI patients. From these findings it would follow that more effective prevention and control of these infections would result in not only a lower incidence of renal failure but also a substantially reduced morbidity and mortality in chronic SCI.
