[Idiopathic vaginal hydrocele. Treatment using a sclerosing injection of minocycline]

The authors report a series of 31 hydroceles (26 patients) treated by drainage followed by sclerosing injection of minocycline hydrochloride. The pain usually experienced with this injection required the use of general anaesthesia in 38.70% of cases and local-regional anaesthesia in 41.94% of cases. The patients were able to return to work on the day after the procedure, but after 6 months, only 51.61% of them were free of recurrence of the effusion. Patients must therefore be warned about the inconstant results of this technique.
