When Praram9 Hospital opened for service in 1992, Dr.Viroon Mavijak, one of the Hospital Founders, who is specialised in nephrology, has started the integrated care & service for patients with kidney diseases since then.

In the first year of Praram9 Kidney Transplant Institute service (1992), there were 5 patients underwent kidney-transplant and all of them had successful operations.

Number of kidney-transplanted patients at Praram9 Kidney Transplant Institute service has been increasing every year. Until now (February 2023), there were more than 1,000 cases of kidney transplantations. This figure indicates that we are the private hospital with the highest number of kidney transplantations in Thailand (and the fourth highest ranking next to Siriraj,Chulalongkorn and Ramathibodi Hospitals, which are all Medical Schools).
