[Lymphoceles after renal transplantation].

Lymphocele following renal transplantation occurs in 1 to 10 p. cent of cases. Pathogenesis and symptomatology are discussed, based on findings in 8 cases. Diagnosis can usually be established by combining ultrasonography and intravenous urography. Asymptomatic lymphoceles require no treatment, but therapy is essential for those producing symptoms or venous or urinary compression. External drainage should be reserved for lymphoceles with spontaneous skin rupture: colloidal gold injections into the fistula orifice may assist drying up of lymphatic leakage. Intra-peritoneal marsupialization appears to be the most widely employed method in other cases, but recurrence is common when used alone. However it constitutes the treatment of choice, when combined with an epiploplasty.
