The rope is seen to be securely wound inside the unidentified man’s bladder in scans that were made public by his doctors.
Because they couldn’t draw the bladder out the same way it went in, doctors had to surgically remove it from the man.
To determine the most effective removal technique, medical professionals built a 3D computer model of the tangled rope using data from thorough scans.
Why the rope was inserted was a mystery to the doctors.
The risky sexual act of “sounding” involves inserting objects into the penis’ opening.
In a medical case report, experts from Dokkyo Medical University in the town of Mibu, 100 km north of Tokyo, described the incidence.
The man complained of dysuria, a painful or scorching urination, and went to the university’s medical center.
Using an ultra sound scan to examine his bladder, medical professionals discovered “a huge item accompanied by acoustic shadows” there. The object was later identified as “a wire-like coiled foreign body” by an X-ray.
The man was then compelled to confess to the medical professionals that he had inserted a skipping rope into the penile urethra.
Professor Toshiki Kijima, the lead author of the case report that was published in the journal Urology Case Reports, said that after the CT scan, medical personnel decided how to best remove the rope.
He claimed that after that, a computer program was used to create a 3D reconstruction of the rope, showing that it had grown too twisted to be extracted from the penis.
The bladder naturally constricts whenever it expels stored urine, which is how the rope became twisted.
