In a series of 2028 patients with chronic renal failure, the diseases
leading to renal failure, the presence or absence of reversible factor
s and their nature, and the rate of decline of renal function of the m
ost common conditions have been described and analysed. Seven diseases
: chronic interstitial nephritis (27.85%), diabetic nephropathy (26.76
%), chronic glomerulonephritis (18.20%), benign nephrosclerosis (10.06
%), chronic pyelonephritis (7.29%), focal glomerulosclerosis (3.20%),
and autosomal dominant polycystic disease of the kidneys (2.07%), acco
unted for 95.43% of all the patients. These diseases were studied in g
reater detail and the results are presented here. It was found that th
ere was a great variation in the rate of decline of renal function in
the different groups, with chronic glomerulonephritis and focal glomer
ular sclerosis progressing most rapidly, diabetic nephropathy slightly
slower, and the others at a less alarming pace. However, once serum c
reatinine had reached 177 mumol/I there was an inexorable decline in r
enal function and the end stage was reached in almost all patients.
