RIO DE JANEIRO — A 27-year-old Brazilian reality TV star who was runner-up in a best-buttocks competition has been hospitalized with complications from a cosmetic procedure to enlarge her thighs.

The Conceicao Hospital Group in the southern city of Porto Alegre said Wednesday that Andressa Urach had an infection in her thighs after receiving under-skin injections of a substance to increase volume in the upper legs. She was hospitalized Monday evening.

Urach earlier had been sedated. But the group said in a statement Wednesday that she later woke up and was taken off a respirator.

She underwent two procedures at the hospital to drain a substance called aquagel that is used in Brazil as an alternative to cosmetic implants.

Urach was runner up in Brazil’s 2012 “Miss Bumbum” contest celebrating shapely bottoms.
