This article aims to describe how to use perineal examination in infants and children. It discusses the indications and stepwise approach to performing a per-rectal examination and interpretation of the findings one could expect to encounter. We include four cases encompassing the major conditions, both congenital and acquired, that paediatricians should be aware of and how they were managed in our institution.
