Observations in Micturating Cystourethrography

Abstract

Combined studies of micturating cystourethrography (MCU), bladder pressure and urinary flow rate measurements (urodynamic studies) have been analysed in 1584 adult patients of both sexes. The combined study is called a videocystometrogram (VCM). The simple MCU is satisfactory for demonstrating vesicoureteric reflux, but in the investigation of other problems of the lower urinary tract in adults, conclusions based on the MCU alone can be misleading. It is recommended that if the MCU is performed at all in the investigation of adult incontinence and suspected urinary outflow obstruction, it should be combined with a urodynamic study. This increases the examination time by about 50% but greatly improves the diagnostic accuracy, especially in establishing whether surgery is indicated or inappropriate.
