The use of penile constricting devices is usually associated with the intention of improving or maintaining longer erections prior to intercourse. Various methods for removal of offending agents in cases of penile strangulation have been described. As far as we know, we report on the first case in the medical literature, in which the GEM ring cutter system is used to treat a case of penile strangulation from a metal ring without the need for general anaesthesia. The GEM ring cutter system works at a low speed and with low torque, in contrast to other highspeed and high torque products. The abrasive discs act by removing one layer of material after another, until a full-thickness cut is made. A metal sleeve comes together with the system, to protect the delicate skin around the treatment area. These features make the system relatively easy to use and safe for the patient.
A 57-year-old Caucasian male presented to the Emergency Department, complaining of penile pain and swelling. He gave a history of placing a stainless-steel cock ring onto the base of his penis prior to sexual activity. This occurred at least 12 hours prior to presentation to hospital. He had previously used the ring without problems, but on this occasion claimed to have forgotten to remove it following intercourse. Upon waking up in the morning, he had tried removing it in the shower with soap and water, but without success. He managed to pass urine without issues prior to arriving in hospital. The patient had no medical co-morbidities. A rapid assessment was conducted by an Emergency physician and the patient was referred directly to the Urology Department. The patient was embarrassed rather than distressed. On examination, a 1cm-wide, 1mm thick stainless-steel ring was trapped at the base of the penis. The penile shaft was severely engorged with superficial necrosis, cyanosis and paraphimosis distal to the constricting device ( ).
Open in a separate windowAfter considering multiple options, the decision was made to cut the ring using the GEM ring cutter (Mooney Ring Cutting System TM) which was available in the Emergency Department. The patient consented for treatment, and a penile block was performed with 1% plain lignocaine. The ring was first cut at the 10 o'clock position and was successfully cut through within 3 minutes. A ring spreader was used to attempt spread to the ring at the defect but was unsuccessful. The ring was therefore cut at a second location, this time at the 2 o'clock position. The ring was then successfully removed off the penis ( ) Throughout the procedure, a metal finger sleeve was used as to protect the penile skin from the abrasive discs. The patient was comfortable throughout the procedure. The paraphimosis was reduced and even though the patient was advised to stay in hospital for observations, he decided to self-discharge. He returned for a review in 2 days, in which there was marked improvement of the swelling and pain ( ). On day 10, he described no issues with having erections or pain, and was formally discharged.
Open in a separate windowOpen in a separate windowPenile constricting devices are typically used to enhance sexual experience, mainly by maintenance of erections. Sustained soft tissue swelling of the penis from constriction may lead to blockage of venous return, and eventually arterial supply. Gangrene or penile amputation may occur in severe cases, and in one case, was fatal.1 Swift recognition and diagnosis is crucial in most circumstances of penile strangulation to prevent serious complications. Penile strangulation is uncommon presentation and a urological emergency created by a constricting device placed round the base of the penis and left there. A literature review revealed reported cases of penile strangulation from rubber bands, metal rings and drinking water plastic bottle neck.2 Depending on the material of the constricting agent, management can be challenging. Methods that have been described include string techniques,3 orthopaedic pin cutter4 and dental drills.5 However; complications can arise from sequelae of treatment such as thermal burns and iatrogenic injury.5
We believe that this is the first report in which the GEM ring cutter system has been described to remove a constricting metal ring from the penis. The device was easy to use, rapidly achieved removal of the offending agent and did so without iatrogenic injury to the penis. A protective finger sleeve and a pair of abrasive discs, diamond and carbide come with the device. The appropriate disc is chosen depending on the type of metal. During the entire procedure, no thermal sparks were created, and the heat generated from grinding was minimal, in fact, no irrigation was needed. The protective finger sleeve was robust enough to ensue no underlying membranous injury.
We recommend that Emergency Department physicians be trained to use this device, so that rapid treatment can be effectively carried to reduce complication rates in these unusual presentations.

We would like to thank Mr Mike Mooney for his assistance of the description of the GEM ring cutter system.
A significant percentage of people wearing jewelry have rings made of tungsten. People choose it for its high polish and its indestructability. Emergency rooms need to be equipped to remove this type of ring.
Tungsten is three times stiffer than steel and much more dense than steel or titanium. These features make tungsten virtually impossible to cut, even with our electric ring cutter or with a high speed diamond cutting disc.
The brittle nature of tungsten, however, makes it very easy to remove, employing the Ring Cracker, a type of vise that squeezes the tungsten ring until it cracks. It works instantly.
This tool should NOT be used to remove rings other than tungsten because it may bend, not break, rings made of other metals (around the patient's finger). We include instructions and specially selected tools to help to confirm that the ring being cracked is tungsten.
Kit also includes safety glasses to protect the patient and a separate pair to protect the clinician removing the ring.
Protect your investment in your electric ring cutter and replacement blades by not forcing them to cut tungsten, which will damage them.
