Sweden-based renal care provider Diaverum has acquired Nefros Asia in Kazakhstan, which operates nine kidney centres in the country.
Terms of the deal were not disclosed.
Diaverum president Dag Andersson said: "Chronic kidney disease and end-stage renal disease is a growing concern in Kazakhstan, like in many other countries in Asia.
"We are committed to being a strong partner to the government of Kazakhstan in bringing world-class specialist renal care to the Kazakh people."
Diaverum will integrate the acquired kidney centres into its global renal care network, which provides services in Europe, Middle East, Latin America and Australia.
The acquired centres are situated in Almaty, Kaskelen, Karaganda, Kokshetau, Kostanay, Aktobe, Aksai and Uralsk. The deal is the first step for Diaverum to expand its operations in the Asian market.
Diaverum Kazakhstan managing director Sardar Sadykov said: "Kazakhstan is currently increasing the number of facilities for dialysis treatments across the country, but the quality is still in need of improvement.
"This is where Diaverum can help. Our focus is to deliver the highest quality of care through our well-trained and motivated healthcare professionals, and through investing in highest quality medical clinics and equipment."
In Kazakhstan, 2,100 dialysis patients were in need of renal replacement therapy in 2013, noted Diaverum. With 8,000 employees, Diaverum provides services in 18 countries in Europe, Latin America, Middle East and Australia.
