Richard had advanced chronic renal disease then often described with the
broad historical term Bright's disease; the clinical report used
evidence of severely atrophied kidneys, uraemia, oedema, anaemia, and
malignant hypertension. “Bright's disease” should not be read as one modern
diagnosis. Later follow-up identified his disease as glomerulonephritis
(Merrill et al.;
Desai et al.).
Confirmation of twin identity was crucial because no effective, acceptably
safe immunosuppressive regimen existed. The team compared fingerprints and
other inherited characteristics, tested blood groups, and observed that
exchanged skin grafts were not rejected. These methods preceded modern HLA
typing; they were used to establish monozygosity, not to discover a close
enough match between ordinary siblings (Merrill et al.).
In adjoining operating rooms, Harrison's team removed a kidney from Ronald
while Murray's team prepared vessels in Richard's lower abdomen. The donor
kidney was placed outside the peritoneal cavity in the pelvis, its vessels
joined to the iliac circulation and its ureter connected to the bladder.
The primary report records an eighty-two-minute period without blood flow
and functional activity after circulation was restored. This pelvic graft
was initially an additional, third kidney; it did not occupy the anatomical
site of either native kidney (Merrill et al.).
Richard's high blood pressure persisted after the graft began filtering his
blood. Only after surgeons removed both of his severely diseased kidneys did
the hypertension resolve. That sequence mattered scientifically: the graft
corrected renal failure, while the native organs continued to drive another
dangerous part of his illness. Success required serial operations, fluid and
electrolyte management, dialysis, laboratory measurement, and nursing after
the headline procedure (Merrill et al.;
Leeson and Desai).
Accounts that reduce the event to “Murray performed the first transplant”
obscure divided responsibility. Harrison accepted and carried out the
operation on the healthy donor; Merrill and the renal service selected and
prepared the recipient; Vandam managed anaesthesia; Gustave Dammin and the
pathology service studied the renal disease; and the hospital's staff
sustained two patients. Murray
himself later presented the institutional programme, rather than a lone
surgeon, as the necessary unit of achievement (Murray;
Desai et al.).
