Chitosan: effects on wound healing in urogenital tissue: preliminary report.

We conducted a survey of the effect of chitosan on wounds of the genitourinary system in dogs. Wounds were made in the kidney, ureter and penile foreskin. Chitosan caused no adverse effects on urogenital wound healing. A decrease in fibrosis was seen in the wounds treated with chitosan in all tissues studied. These observations suggest that the morbidity of urogenital surgery may be decreased by treating the wounds with chitosan.
