A woman and her husband are suing Juntendo University Hospital in Tokyo for ¥140 million in damages, claiming the wife suffered a uterine rupture and a stillbirth after she was administered drugs without her consent during delivery using anesthesia to reduce the pain, their lawyer said.

Yoshinori Sadatomo, the couple's attorney, said Tuesday that he also submitted a request to the health ministry demanding that it revoke the hospital's designation as a special treatment institution that offers high-level medical technology.

"The couple chose Juntendo thinking it was well-equipped, but they were not given high-level and safe medical treatment," Sadatomo said.
