[Urethral substitution with synthetic material].
In spite of the numerous surgical techniques described, management of urethral stenosis continues to be an unresolved problem. Free graft urethroplasty is indicated in selected cases and several organic and synthetic materials have been described for this use. Our group reviews the synthetic alloplasts used for partial or total replacement of the male urethra. The search for an appropriate alloplast for urethral replacement has been rather frustrating. Complication rates are still too high to allow routine usage. The most encouraging results are those with new absorbable materials which cause minimal inflammatory reactions of a foreign body type. These are readily available and allow urethral replacement using tissues regenerated from removed ends.
