The excisional, plication and internal drainage techniques: a comparison of the results for idiopathic hydrocele.

Abstract

To assess the results of the excision, plication and internal drainage techniques for hydrocele repair. Between January 1990 and June 1998, 132 patients (mean age 54.36 years, range 16-83) underwent repair for idiopathic hydrocele using one of three techniques (excision, eversion/plication or internal drainage); the complication and recurrence rates of each technique were evaluated. The excisional technique resulted in the highest complication rate (81%) and the internal drainage technique the lowest (7%). Postoperative scrotal oedema occurred in 74% of patients after plication and this was the highest rate among the techniques (P < 0.001). Differences in the rates of wound infection and haematoma among the three techniques were not statistically significant. The internal drainage technique had the highest recurrence rate (85%) and the excisional technique the lowest (1.3%; P < 0.001). Although useful, the internal drainage technique has a high recurrence rate and we suggest abandoning its use for hydrocele repair. The present results suggest that plication is better than excision, causing fewer complications, and better than internal drainage, as the results are more favourable.
