The disgraced New York City urologist charged with fondling underage boys and adult male patients has been accused of sexually abusing another 28 people — bringing his tally of alleged victims to at least 70.

Darius Paduch — a urologist who worked at NewYork-Presbyterian Weill Cornell Medical Center and Northwell Health before his arrest — was busted in April for allegedly sexually abusing patients under the guise of medical treatment from 2015 through 2019.

A group of 28 new lawsuits filed in Manhattan Supreme Court on Monday against the two medical institutions involve more former patients who say the doctor sexually assaulted them and that the hospitals were negligent in allowing the incidents to occur.

The hospitals “knew or should have known that Dr. Paduch might use his position as its employee … to sexually abuse its patients,” the suits allege. But the institutions “failed to take reasonable steps to protect” the victims, the filings claim.

Criminal charges were brought against Paduch after he was first sued in December by a 16-year-old male high-school intern who claimed the doctor sexually abused him from 2015 through 2017 while he worked at NewYork-Presbyterian.

Since then, many more alleged victims have come forward, with the latest batch of suits including allegations that several more underage boys were abused by Paduch.

The new cases also claim that Paduch’s abuse spans back a decade.

“We hope the victims of Dr. Paduch know that they are not alone, and that these hospitals are complicit in their failure to protect patients,” said Mallory Allen, who represents the 70 alleged victims, in a statement.

“Even after being made aware of the abuse, both institutions failed to properly investigate these concerns and allowed Dr. Paduch to continue practicing medicine and seeing patients for over a decade – and, to this day, have still not informed their patients of the truth behind his sexual abuse of patients or their rights to recourse,” Allen said.

The lawyer noted that victims only have until Nov. 23 to file suits under New York’s Adult Survivors Act.

The legislation has allowed people for a limited time to bring claims against alleged abusers and the institutions that may have protected them even if the claims are outside of the state’s statute of limitations.

A rep for Northwell Health noted that the doctor no longer works with it and added that the hospital will cooperate with the authorities as part of their probe.

“Northwell Health strives to provide the highest level of care to its patients, patients’ families and communities,” the hospital representative, Barbara Osborn, said. “We are deeply disturbed by these allegations and take them very seriously.”

A Weill Cornell rep added in an e-mailed statement that its institution “values the care and safety of our patients above all else, and we are taking these matters very seriously.

“The acts described are disturbing and appalling, and we feel deeply for those involved. We are fully cooperating with law enforcement, and Cornell’s Office of General Counsel has engaged outside counsel to conduct a comprehensive investigation into the behavior of former WCM faculty member Dr. Paduch and the circumstances surrounding the allegations. 

“Unfortunately, the ongoing nature of the investigation, as well as pending litigation, prevents us from being able to comment further,” the statement said.

Paduch’s criminal defense attorney did not immediately return a Post request for comment Monday.
