The state Superior Court has granted a new trial to a woman who suffers from kidney failure in a medical malpractice case, ruling that she should have been able to introduce testimony from her expert detailing how a prescription drug and lack of monitoring contributed to her condition.

On Jan. 7, a three-judge panel said the plaintiffs in Klein v. Aronchick are entitled to a new trial, reversing a Philadelphia judge’s ruling that Dr. Craig Aronchick’s alleged negligence could not have been a factual cause of Marsha Klein’s renal failure.
