Abstract
The characteristics of end-stage renal disease (ESRD) complicating spinal cord injury (SCI) were studied retrospectively in 43 male hemodialysis patients. A control group of male patients dialyzed in the same institution were studied for comparison. The SCI patients had significantly lower serum creatinine concentrations and daily urinary creatinine excretion than the control group, despite comparable creatinine clearances. Therefore, serum creatinine, when compared with the familiar values in non-SCI patients, may greatly underestimate the severity of the renal impairment. Urine optput was higher, urine specific gravity lower, and renal glucosuria more common in the SCI patients. 24-hour urinary protein excretion was higher and serum albumin was lower in the SCI patients, with 48% of the patients exhibiting nephrotic range proteinuria. Urine pH was markedly elevated, and pyuria and bacteruria were present in all SCI patients. Fractional excretion of potassium (159 ± 16%) exceeded its filtered load in most SCI patients.
