Peak retrograde flow can serve as a valuable tool in predicting persistent, progressive and new onset asymmetry. Varicoceles associated with a peak retrograde flow of 38 cm per second or greater and 20% or greater asymmetry should be considered for varicocelectomy at initial presentation. Patients with peak retrograde flow greater than 30 cm per second need to be monitored carefully. Those with peak retrograde flow less than 30 cm per second are less likely to require surgery.

Laparoscopic lymphatic sparing varicocelectomy is preferable to an open or laparoscopic Palomo repair that does not preserve the lymphatics. It has a significantly lower incidence of postoperative hydroceles, especially those requiring surgical intervention, and still maintains a low incidence of persistence/recurrence. The procedure is especially advantageous for bilateral varicocelectomy.
