Congenital hydrocele: prevalence and outcome among male children who underwent neonatal circumcision in Benin City, Nigeria.
OBJECTIVE
To determine the prevalence and spontaneous resolution of congenital hydrocele diagnosed in male neonates who underwent circumcision at our centre.


METHODS
All male neonates presented for circumcision at the University of Benin Teaching Hospital, Benin City, Nigeria between January 2002 and December 2006 were examined for the presence of hydrocele. Those diagnosed with this condition were recruited and followed up in a surgical outpatient clinic for 2 years. The number of cases of spontaneous resolution and age at which this occurred were documented on a structured pro forma.


RESULTS
A total of 2715 neonates were circumcised and 128 (4.7%) were diagnosed with 163 cases of hydrocele, while 27 cases in 25 (0.9%) children failed to resolve at the age of 2 years. Neonatal hydrocele was bilateral in 112 (68.7%), and there were 20 (12.3%) right and 31 (19.0%) left. Among those with hydrocele, 28.1% were delivered preterm and resolution was spontaneous in many of them, with no observed significant statistical difference to those delivered full term (P=0.4740). Of the 163 hydrocele cases, 136 (83.4%) resolved spontaneously by age 18 months with peak resolution at 4-6 months. No spontaneous resolution occurred after 18 months and no hydrocele-related complication occurred during follow up.


CONCLUSIONS
Neonates with congenital hydrocele should be observed for spontaneous resolution for at least 18 months before being subjected to surgery.
