[Transrenal ureteric embolisation. Experimental and clinical results (author's transl)].
Transrenal ureteric embolisation with the tissue adhesive butyl 2-cyano-acrylate mixed with lipiodol and tantalum powder produces rapid and effective occlusion of the ureter. This can be combined with the use of a Gianturco spiral. In an experimental series of eight dogs observed for 54 days, the adhesive disappeared partly in three animals and totally in a further three. Fibrotic ureteric stenosis was observed in three animals. Clinical results were rather better because of the presence of external urinary drainage. Twenty-one ureters in eighteen patients were occluded either unilaterally or bilaterally, and sometimes combined with percutaneous contralateral renal embolisation. After one to four months, the ureter was still occluded in three out of six cases; after five to 17 months, three out of five cases were no longer totally occluded, but in two cases they were still blocked. The procedure is new and suitable for the treatment of otherwise untreatable conditions, such as extensive urinary fistulae, bladder tenesmus and haematuria due to extensive tumours of the minor pelvis.
