[Renal tumour embolization: a seven year experience (1986-1992)].

The authors present their experience in renal tumour embolization (renal angioinfarction) over a seven-year period (the previous results--1981-1985, are reported). In this period 99 renal angioinfarctions due to malignant renal tumours were observed. Sixty nine renal angioinfarctions were treated preoperatively (before radical nephrectomy), and 30 angioinfarctions were "palliative"--as the only mode of treatment. The authors analyzed the impact of renal angioinfarction before nephrectomy in 69 patients, compared with 57 patients in whom nephrectomy was the only treatment. The obtained results support their previous reports: renal angioinfarction facilitates the operation, minimizes intraoperative blood loss, and probably, prolongs the survival.
