Observations on hydroceles following adolescent varicocelectomy

Purpose: 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. Materials and 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.
