AMSTERDAM, Netherlands, April 18 A young woman has died from undetermined causes after undergoing liposuction surgery in Utrecht, the Netherlands.Health care officials were investigating the 21-year-old woman's death at a private clinic Tuesday, Expatica and ANP reported.The woman was transferred from the Biltstraat Medical Center following the surgery to a nearby hospital after undergoing complications.Liposuction is not commonly seen as excessively risky surgery, but a 2004 health report in the Netherlands said conditions and quality of care varied greatly at such private clinics.The report said that many of the clinics, which are growing in number in the country, did little to meet hygiene standards for medical procedures.Expatica and ANP said that in light of such reports, the nation's ZKN health organization is urging stricter standards for clinics and has asked insurance groups to deal only with qualified facilities.Copyright 2007 by UPI
