Sclerotherapy with tetracycline for hydroceles in renal transplant patients.

A total of 17 patients with hydroceles following renal transplantation underwent sclerotherapy with tetracycline hydrochloride (10 ml. of a 5% solution of tetracycline in 1% lidocaine). A successful outcome was obtained in 15 patients (88%). Post-sclerotherapy hydrocelectomy was necessary in 2 patients (12%). No major complications (testicular loss, scrotal abscess or necrosis) occurred in any patient. Pain at injection was the only adverse effect. Tetracycline sclerotherapy for hydroceles appears to be an effective and safe procedure in the renal transplant population. We recommend this procedure as the initial treatment modality for hydroceles in patients with a renal allograft.
