"Urological cold shower"--a novel treatment for intraoperative erection

Intraoperative penile tumescence during endoscopic surgery is a troublesome complication and a challenge to the urologist. We describe a novel, convenient, safe, and readily available technique. We used an intracavernosal injection of epinephrine using a standard dental syringe and a cartridge of lidocaine 2% and epinephrine 1:80,000 to induce detumescence reliably.
