Are mechanical and chemical trauma the reason of meatal stenosis after newborn circumcision?

Abstract

Mechanical and chemical trauma are a widely accepted theories to explain the pathogenesis of meatalstenosis after newborn circumcision. The aim of the present study was to explore the theory that an exposed glans is prone to meatal stenosis. This was done by a novel investigation of boys who were born with hooded prepuce, a condition in which the glans is completely exposed. Physical examination, lower urinary tract symptoms, urethral meatus configuration, and surgical procedures of 18 children admitted for routine circumcision, who had congenital hooded prepuce with normally located urethral meatus, were analyzed. The study period was 2013 and 2018. All the cases have been seen because of neonatal circumcision request, but was postponed due to hooded prepuce. The only presenting complaint in children was a cosmetically unattractive appearance. There were no symptoms associated with meatal stenosis, they circumcised in an average of 6 years and non of them required any additional procedure.Conclusion: Meatal stenosis did not occur in cases whose glans penis are naked with hooded prepuce. These findings do not support the default chemical and mechanical trauma theories. Hooded prepuce without any penile anomalies is only a cosmetically unattractive appearance and circumcision can correct this.
