I recently heard a talk by a visi ting scholar who was researching the candir. The speaker was collaborat ing with a South American medical doctor who completed a candir removal operation in 1997. The fish had entered the (male) patient's urethra, h ad been stopped by the urethral sphincter (if that's the right term), an d had turned at a right angle and burrowed into the scrotum. The fish ha d died, and the subsequent relaxation of its spines facilitated removal. A photograph of the removed fish and part of the affected area was presented. According to the speaker, the patient claimed the fish had sw um out of the water up his urine stream. In my original column I expressed s kepticism about Willy-in-the-willy, noting an absence of firsthand or ev en secondhand accounts. And now here comes a guy who's got eight-by-ten glossy photographs. I've been in contact with Paulo Petry, the scientist you heard, who related the following astonishing tale. Petry is an expert in neotropical ichthyology and vice president of Bio-A mazonia Conservation International, a not-for-profit conservation group. While working in the Amazon city of Manaus, Brazil, he noticed a hubbub in the press about Anoar Samad, a urogenital surgeon who had performed the world's first confirmed removal of a candir from a human penis. Wha t's more, Samad had a live patient and a dead fish to prove it. Herewith an except from an ar ticle the two are coauthoring with fish physiologist Stephen Spotte: On 28 October 1997, one of us (Samad) attended a 23-year-old man from th e town of Itacoatiara on the Amazon River who sought medical attention with obstruction of the urethra, having been attacked by a candir. Pri or to being attended, the patient remained untreated for three days and was only administered medication for pain.
The patient was ane sthetized with 5% lidocain and the procedure was performed. The fish wa s grasped using an alligator-clip attachment on the endoscope and remov ed in one piece. Fortunately the fish was dead, and decay was beginning to soften its tissues. Tension on the spines had relaxed in death, and they no longer gripped. Had the candir been alive, its removal would have been more difficult and resulted in greater trauma to the patient.
He reported tr ying to grab hold of the fish, but it was very slippery, and it forced its way inside with alarming speed. The candir's forward progress was blocked by the sphincter separating the penile urethra from the bulbar urethra. With the passage blocked, the fish had made a lateral turn and bitten through the tissue into the corpus spongiosum, creating an open ing into the scrotum.
of the urethra with sterile distilled water prior to endoscopy induced further immediate and pronou nced scrotal edema, making it evident that the opening had allowed the perfusate to enter the scrotum.
Some coagulated mate rial was removed, revealing a wound on the bulbar urethra of 1 cm in di ameter and associated with a small amount of local bleeding. Although t he patient suffered immediate trauma, no long term effects of the attac k were noticed 1 year after the incident.
photos, a videotape of the procedure, medical reports, and of course th e fish, which was donated to an Amazon research institute. "According to him, he was standing in the water thigh deep, urinating with his penis out of the water yet close to it. He repeated the same version more than once when asked to describe the incident to Dr. Research by Petry and Spotte found no indication that the fish is particu larly attracted to urine. Petry adds, "The only way that the fish could enter the urethra is while it is expanded during urination, otherwise I don't think it could move in." And here you thought the worst thing you could do was pee on the third rail.
