Abstract

Backgraound: Biopsy/excision is an essential urological procedure for diagnosis and treatment of potentially malignant penile lesions. Local and general anaesthesia are not without risk, as well as the associated cost. EMLA (eutectic mixture of local anaesthetic) cream is a mixture of prilocaine/lidocaine in a water-soluble base, which is absorbed through the epidermis. It is widely used in neonatal circumcision and vasectomy1 as well as showing promise in lithotripsy.2 We describe the technique of biopsy/excision of penile lesions using EMLA as a sole anaesthetic agent. Technique: After the lesion has been assessed as suitable (regarding size) informed consent is obtained. In the day-surgery unit, the lesion is cleaned and EMLA cream applied. This is secured by adhesive dressing (e.g. Tegaderm™) which is removed 40 min later in theatre. Painful sensation is then assessed by means of an analogue scale with a sterile hypodermic needle. In our unit, 8 patients underwent this procedure. In all, the anaesthesia was adequate for biopsy/excision. The ratio of biopsy to excisions was 3:1. All specimens were sufficient to give a diagnosis and all excisions were complete. The average area of the specimen taken was 8.75 mm2 (range, 5–16 mm2) with an average depth of 1.25 mm (range 1–2 mm). There were no complications. Discussion: EMLA cream as a sole anaesthetic agent is an effective, low-risk and cost-effective alternative for biopsy of penile lesions. Excisions require judicious selection and are limited by size. This technique enables rapid diagnosis and treatment, allowing transfer to the day ‘office urology’ surgical en
