Abstract:
Size of the external urethral meatus in adult Indian males is not yet documented. However, for choosing optimum size of an instrument, it is important to know the maximum stretchable external urethral meatal size in a particular patient. Hence, a prospective study was conducted at our institution to document the maximum stretchable adult male external urethral meatus size. After obtaining consent, 340 adult males who were undergoing urethral instrumentation for reasons other than the diseases of the urethra underwent urethral calibration using a "urethral calibrator" during February 2009 to April 2010. Data were analyzed using the SPSS 17. The average maximum stretchable external urethral meatal size in an Indian adult male was 28.49 Fr. Ours is the only study to document the maximum stretchable adult external urethral meatal size in Indian males which helps us for better instrumentation.
