OBJECTIVE: Endoscopic surgery is one of the most common minimally invasive surgical techniques applied in the field of urology. The authors developed a mechanical adaptor for commercially available penlight-type LED light that can be used in common endoscopic procedures in urology.

MATERIALS AND METHODS: A four-piece light adaptor device made from medical-grade aluminum steel was crafted and functions as an adaptor for penlight-type LED light in one end and an endoscopic telescope on the other end. In order to determine its function and quality, it was compared to the conventional light source machine used in most endoscopic procedures. The specification of both light sources were compared in terms of light intensity and colour temperature through a light meter. This device was applied clinically by using it in a series of endoscopic procedures.

RESULTS: Application of the device in the endoscopic surgical procedures showed that it functioned well and appropriately. It was able to complete a full course of each operation undertaken.

CONCLUSION: This original an innovative device offers an alternative to the conventional light source equipment available commercially. Based on the authors experience we recommend the use of this adaptor for common endoscopic procedures done in minimally invasive surgery.

A 19-year old man presented with acute onset of intractable hypertension with associated dizziness and nausea. Abdominal computed tomography revealed a 7.0cm x 6.27cm x 6.0cm suprarenal mass on the right. The patient was diagnosed to have pheochromocytoma and successfully underwent retroperitoneal laparoscopic adrenalectomy.

A patient with known prostatic cancer presented with left supraorbital swelling with proptosis and restricted eye movements on left eye. Contrast enhanced computed tomography scan revealed dural and bone metastases with soft tissue component extending to the left orbit. Serum prostate specific antigen was markedly elevated at >100 ng/ml. Incision biopsy of the orbital tumor revealed only lymphocytic inflammatory cells within the fibrous stroma attributed mainly to the deeper location of the tumor or shallow locus of the biopsy. Incisional biopsy of the frontal bone revealed atypical looking cells in sheet cluster with nuclear enlargement, hyperchromatic in irregularity confirming the diagnosis of orbital metastasis of prostate carcinoma.

Metastasis of prostate cancer to the orbit is rare. One should have a high index of suspicion of orbital metastasis when presented with an elderly patient with ocular symptoms and a history of prostate adenocarcinoma. A thorough clinical, radiological and histological evaluation is necessary to establish the diagnosis.
