Penile incarceration with metal objects--a review of procedure choice based on penile trauma grade.

摘要

OBJECTIVE: To outline treatment guidelines according to level of penile trauma for penile incarceration by metal devices. METHOD: A post-1950 (hand-held powered cutting tool era) Medline search was performed. Cases were divided into four groups: string techniques and variants with and without aspiration of blood from the glans; aspiration techniques; cutting devices; and surgical techniques. Trauma grade (according to Bhat et al., 1991), site time (incarceration time), removal technique, removal time, anesthesia and recovery time were assessed. RESULTS: The string technique and variants were used for grades 1-3. They had short removal (30-120 min), site (3-72 h) and recovery (1-24 h) times. Occasional glans decompressive with blood aspiration was required. Anesthesias included none (wrapping without glans aspiration), i.m. morphine and general (glans aspiration). Pure aspiration techniques used multiple needle punctures for grades 2-3. Aspiration cases had short site times (8-14 h), but required a spinal or general anesthesia. Cutting device cases (grades 1-5) required general anesthesia, had a short removal times (45-90 min), but long site (7 h-30 days) and recovery (2-66 days) times. Surgical degloving was utilized mainly for grade 5 cases, required spinal or general anesthesia, had short site (2-30 days), but long recovery (9-28 days). CONCLUSIONS: The string, wrapping, aspiration techniques and cutting devices are suited for grades 1-3. Cutting requires a shield to avoid blade trauma and water-cooling to prevent thermal injury. Suspected underlying devitalized tissue (e.g. grade 4) is examined by Wood's lamp. Failure to identify gangrenous tissue will result in post interventional complications and a prolonged recovery time.
