In a curious addendum to the Dick Clark story, TMZ reports that the TV icon had undergone prostate surgery the day before he suffered the massive heart attack which killed him April 18 at the age of 82.

The revelation comes thanks to Clark's death certificate, which TMZ has posted on its site.

"According to the report," TMZ says, "doctors performed a transurethral resection of the prostate for benign prostatic hyperplasia on April 17. The procedure is usually performed when the prostate is so enlarged, it makes it extremely difficult to urinate."

Neither the death certificate nor TMZ suggests the heart attack occurred as a result of the surgical procedure.
