Before that time, the Uruguayan basketball championships were only local metropolitan, and no competitions brought together all the clubs in the country.

Until the Liga Uruguaya de Básquetbol was created, the capital clubs participated in the Campeonato Uruguayo Federal de Básquetbol (Uruguayan Federal Basketball Championship), while the clubs of the rest of the country competed in regional tournaments.

The first LUB competition had a dramatic end, with a win in the last second, that brought the Uruguayan League title to Defensor Sporting, whom also repeated in the 2009–10 season.

The LUB is currently played in four stages: Torneo Clasificatorio (Qualifying Tournament), Ronda Título (Title Round) or Reclasificatorio (Requalifier), play-in and play-off.

Before that time, the Uruguayan Federal Championships were only local, and no competition brought together all the clubs in the country.
