Single Kidney Outcome and Management in Persons with Spinal Cord Injury

Abstract This case study examined the outcomes of persons with spinal cord injury (SCI) who had a single kidney. A Urologic Database, including 1655 persons with SCI between 1969 and 1997, was examined and 22 persons were identified with single kidneys. Twenty persons had adequate follow-up. Renal function was measured by total and individual kidney effective renal plasma flow (ERPF). Of 11 persons who had a single kidney prior to injury or as a result of an associated injury, all maintained a normal ERPF for an average of 8.6 years. Of 9 persons who had removal of a kidney following their injury for other diseases or urinary complications, 3 were deceased, but 2 had a normal ERPF in the remaining kidney prior to death. One with vesicoureteral reflux had decreased renal function in the remaining kidney. Recurrent renal calculi in a single kidney carries risks for decreasing renal function, urosepsis, and death.
