Chemical composition of gases surgeons are exposed to during endoscopic urological resections.

Objectives: To identify any potentially harmful chemical constituents of the gaseous plume produced from urological endoscopic diathermy.

Methods: Chemical analysis was performed on the gaseous plume produced from prostatic resections and vaporizations using gas chromatography with mass spectroscopy and high-performance liquid chromatography using ultraviolet and visible light detection. In addition, carbon monoxide levels were analyzed using a portable catalytic flammable gas sensor.

A case report of spontaneous rupture of a renal angiomyolipoma in a post-partum 21-year-old patient.

Introduction: Renal angiomyolipomas (AML) are benign tumours containing vascular, smooth muscle and fatty elements. The majority of renal AML run an asymptomatic, benign course. The main associated complication is that of retro-peritoneal or intra-tumoural haemorrhage.
