Results of window operation for primary hydrocele.

The window operation for hydrocele repair has been reported to be a safe out-patient procedure, with few complications and relapses. In this pilot study the procedure could be safely done on an out-patient basis and the rate of complications (8%) was comparable to that of other procedures. However, 21/23 evaluated hydroceles relapsed and retreatment with a second window operation led to further relapses within a short time. Eight patients with 11 hydroceles required another procedure. We have therefore abandoned the window operation for hydrocele repair.
