This patient has a urtheral stricture, which is a narrowing of his urethra. It's causing him some difficulty in passing urine. The treatment advised by the Doctor is to have a sound passed down his penis to clear any blockage. The first sound went in so easily that the Nurse decides the patient would benefit from passing another one down so he has 2 sounds invading his urethra at once. She hopes this will cure his problem. Watch as the 2 sounds are manipulated within his urethra, encouraging it to open wider.
