An elderly dementia patient strangled his own penis after wrapping rubber bands around it and leaving them on for three days. 

The unidentified 81-year-old had to have emergency surgery in Chicago, Illinois, after the skin on the tip of his member started to rot.

Yellow and purple patches began to appear on the shaft and base of his penis, too, due to the lack of blood supply. 

Experts said the patient's penis could have fallen off if doctors hadn't removed the bands when they did. 

The African-American man, whose grisly case was published in a medical journal, was originally admitted to hospital due to complications from his diabetes.

His wife turned medics' attention to the rubber bands, which she said her husband had refused to remove for between two to three days.

Doctors at the University of Chicago Medical Centre operated to prevent further degradation. 

Dead tissue was removed using a hot wire and scalpels and antibacterial lotions were applied as he recovered over five days.  

A catheter — a tube put through the urethra — was used to drain the urine that had built up in his bladder as he'd been unable to urinate.

He recovered well from the surgery but failed to return for a check-up appointment two-weeks after leaving the hospital. 

The patient had originally went to hospital after suffering diabetic ketoacidosis — a potentially deadly reaction to low levels of insulin.

When doctors asked him about the rubber bands, the man appeared to be confused. 

WHAT IS PENILE STRANGULATION? 

Penile strangulation is a rare but often dangerous medical emergency that occurs when an object or body part blocks the blood supply to the penis. 

In the worst cases, the lack of blood flow can result in gangrene and the death of tissue — penile necrosis.

Medics have devised a grading system to indicate the severity of strangulation: 

Grade 1: Edema of distal penis. 

Grade 2: Injury to skin and constriction of corpus spongiosum, but no evidence of urethral injury. Distal penile edema with decreased penile sensation. 

Grade 3: Injury to skin and urethra but no urethral fistula. Loss of distal penile sensations. 

Grade 4: complete division of corpus spongiosum leading to urethral fistula and constriction of corpora cavernosa, with loss of distal penile
