Trattamento percutaneo delle cisti renali sintomatiche: effetti dell'associazione di scleroterapia con alcol e di colla di fibrina (Tissucol)

The percutaneous treatment of symptomatic renal cysts has grown in therapeutic importance over the last years. The international literature includes many reports on the sclerotherapy of renal cysts with different sclerosing agents. The authors report their experience with the percutaneous treatment of renal cysts by combining pure alcohol and fibrin glue. The glue serves the purpose to seal the walls of the cyst already damaged by alcohol. The results of the combined treatment show that relief of symptoms was obtained in all patients, with no major or minor complications. Complete cyst ablation was obtained only in 16% of cases, while a partial recurrence was seen in 80% of patients, with an average regrowth < 35% of the initial cyst volume. None of these patients presented further symptoms. At present, the follow-up time ranges 3 to 34 months.
