On June 1, 2009, the defendant surgeon Dr. Aaron Siegel agreed to assist a urologist during a urological surgery on 60-year-old Ivory Lakes at the Advocate Condell Medical Center in Libertyville, Ill. She had been a patient of Dr. Berger, the urologist, for about a year, treating for retroperitoneal fibrosis. Retroperitoneal fibrosis is a condition that causes urinary flow problems in both ureters. The surgery involved a procedure to free the ureters and encase the ureters with tissues harvested from the patient; the procedure was designed to prevent recurrence of the urinary flow problem.
Dr. Siegel’s role at the surgery was limited to being an assistant to Dr. Berger. Dr. Siegel never met the patient before she was placed under anesthesia, and Dr. Siegel did not know anything about her medical history or what specific procedure was planned.
During the surgery, Dr. Siegel held retractors, provided visualization for Dr. Berger and suctioned fluids from the operative field. However, one of the ureters tore when Dr. Berger grasped it, and it then it disintegrated when he tried to grasp it above the tear. Dr. Berger than decided to remove the kidney due to the lack of a viable ureter.
