The rate of hydrocele perforation during vasectomy. Is perforation dangerous?

BACKGROUND

Hydroceles are not uncommon, are often occult, and may be associated with an inguinal hernia. The rate of hydrocele perforation during elective vasectomy has not been reported in the medical literature. Our objective was to estimate the frequency and consequences of hydrocele perforation incidental to vasectomy.

METHODS

We retrospectively reviewed data from a series of patients undergoing vasectomy using the no-scalpel technique for the incidence of complications. A supplementary chart review was done to determine preoperative conditions, and telephone contacts were made if needed to assess later morbidity.

RESULTS

We noted 7 perforations in 150 vasectomies. Only one patient had a hydrocele documented preoperatively. Three had histories of inguinal hernia and herniorrhaphy. Five patients had evidence of minor swelling early on, but none had additional morbidity or long-term associated complications.

CONCLUSIONS

This small case series of vasectomies had a 4.7% incidence rate of perforated small or occult hydroceles. Physicians should be aware of this potentially alarming but apparently minor phenomenon that may accompany vasectomy.
