Then the University was restructured on a unitary pattern and the previous constituent colleges (Rangoon College, Judson College, Medical College and Teacher Training College) became the Faculties with the respective Dean as the Head of each Faculty. As the result of these activities, the Medical College was transformed into "Faculty of Medicine", under the University of Rangoon with effect from 26th September 1946.

Dr. W. Barridge was appointed as the First Dean of the Faculty of Medicine.

Dr. U Min Sein was appointed in 1946 as Professor of Medicine and he was one of the Professors of post-war Rangoon University.

The Faculty of Medicine opened its classes in 1946, accepting the old pre-war students of medical college. The new intake of 30 students began in 1947.

Professor U Min Sein became the Dean of the Faculty of Medicine in 1947.

On the declaration of independence of Burma on the 4th January 1948, all the senior British and Indian officers of Health Department and the Faculty of Medicine left Burma. The position of National Health in Burma was far from satisfactory. The then Burma Medical Council tried for re-employment of the retired doctors and asked for the aid of private practitioners for part time employment in government service but these efforts were not successful. There were shortages of doctors in Hospitals, the Health Departments and the Faculty of Medicine. The need was felt most acutely in the rural areas. Very few qualified doctors rallied to the need of the country, and the Faculty of Medicine was kept going with inadequate equipment and teaching personnel.
