Abstract

We report a case of a 37-year-old male who presented with a 12-hour history of a strangulating 2cm wide by 0.8 cm thick metallic nut on the penile shaft at the peno- scrotal junction. Unlike instances where these metallic objects are placed to enhance sexual stimulation this nut was rather placed to prevent intercourse. A Bosch electric circular grinder was successfully used for removal but a thermal burn to the penile tissues was sustained in the process as the hardness of the nut required a high energy to cut and its thickness did not allow for effective cooling during the process of removal. This resulted in a circumferential denudation of penile skin, a urethro-cutaneous fistula at the penoscrotal junction and a mid-bulbar urethral stricture. The penile wound was subsequently covered with a split skin graft with a delayed closure of the urethrocutaneous fistula and a buccal mucosa patch urethroplasty for the mid bulbar stricture. Despite the degree of thermal burns sustained the patient has maintained good erectile function with grade four rigidity. The tunica albuginea and the underlying corpora cavernosa have shown a significant degree of resilience to thermal burns compared to the corpora spongiosum where the thermal burns led to a urethrocutaneous fistula.
