Transplants of all kinds increased in Spain, particularly lung replacements, up nearly 20 percent, and pancreas transplants, up more than 10 percent, the health ministry said.
A record total of 4,279 transplants were carried out in Spain in 2013, of which 2,552 were of kidneys, 1,093 of livers and 285 of lungs, it said.
"The Spanish transplant system, which has been the world leader for 22 years, has again demonstrated its vitality," said the head of the state National Transplant Organization (ONT), Rafael Matesanz.
"Its activity increased in 2013 in very difficult circumstances," he told a news conference, presenting a transplants report.
Spain's government in 2012 cut the annual national health budget by €7 billion euros ($9.6 billion) a year in its efforts to strengthen public finances, causing waiting lists for non-urgent surgery to lengthen.
But the national transplant system has thrived over the years, with the number of donors increasing from 14 per million people in 1989 to 35 per million in 2011, Matesanz said.
That put Spain far ahead of other countries, with 26 donors per million people in the United States, 25 in France and just under 15 in Germany, according to the transplant body's latest figures from 2011.
