Evaluation and management of the persistent/recurrent varicocele.

OBJECTIVE

To review outcomes in adolescent patients following redo varicocelectomy surgery.

METHODS

The composite varicocele registry of a single surgeon was queried to identify patients who had undergone redo varicocelectomy. Variables of testicular asymmetry, testicular volume, presence and degree of retrograde venous flow, and incidence of postoperative hydrocele were evaluated.

RESULTS

Nineteen boys were identified as having had a redo varicocelectomy (16 open, 1 laparoscopic, 2 radiographic embolization) with a minimum postoperative follow-up of 6 months (mean: 23.4; range: 6-53 months). No varicocele was palpable postoperatively among the 17 surgical redoes; one patient's testicle was significantly smaller after surgery, and 3 developed a hydrocele requiring repair. One of two boys who underwent radiographic embolization had a persistent varicocele. Eight of the nine boys who had asymmetry of 10% or greater before redo demonstrated catch-up growth after repair. The consistent intraoperative finding in all redo patients was the presence of large veins within the cord, just proximal to the junction with the vas and in continuity with the dilated veins distal to the internal ring. Post-redo retrograde venous flow was not identifiable in 16 and minimal in three.

CONCLUSIONS

Redo varicocelectomy can be accomplished successfully and has a similar chance of achieving catch-up growth as does an initial repair. Postoperatively, there exists a small risk of testicular volume compromise and a significant risk of hydrocele development. Distal collateral veins may have a smaller role in varicocele formation and recurrence than previously thought.
