Observations on hydroceles following adolescent varicocelectomy.
OBJECTIVE
There is wide variation in the reported incidence of hydrocele after varicocelectomy (0% to 29%). We determined the incidence of hydroceles and hydrocelectomy following adolescent varicocelectomy, the time it took for them to manifest, and the results of aspiration and surgical correction.


METHODS
Our adolescent varicocele registry was reviewed to identify patients with a post-varicocelectomy hydrocele. We evaluated physical examination and ultrasound findings, postoperative interval to development and treatment results.


RESULTS
A total of 400 patients with at least 6 months of postoperative followup underwent 521 varicocelectomies (16 redo, 1 right, 104 bilateral) from 1987 to 2010. Mean followup was 32 months (range 6 to 182). Hydrocele was detected in 80 of 521 (15.4%) at a mean of 2 years after surgery. The incidence of hydrocele was higher in open vs laparoscopic (p <0.001), bilateral vs unilateral (p = 0.013), nonlymphatic sparing vs lymphatic sparing (p = 0.043) and Palomo vs laparoscopic nonlymphatic sparing (p = 0.001) procedures. Eight patients underwent aspiration for a large postoperative hydrocele. In all 8 patients fluid returned to pre-aspiration status. There were 29 patients (5.6%) who underwent Jaboulay bottleneck hydrocelectomy and none had recurrence.


CONCLUSIONS
Hydroceles are a common sequela of varicocelectomy, with the fewest hydroceles occurring after laparoscopic lymphatic sparing varicocelectomy. Patients should be followed for at least 2 years after varicocelectomy to examine for the presence of hydroceles. Although there have been reports on the use of aspiration for post-varicocelectomy hydrocele, we have not had success in those with a single aspiration. Jaboulay bottleneck hydrocelectomy had a 100% success rate in this select group.
