Purpose:
Evaluation of superselective embolisation of renal tumours in inoperable patients with solitary kidneys.
Methods And Patients:
Eight inoperable patients with solitary kidneys bearing tumour nodules underwent 1-3 superselective embolisation procedures with ethibloc (5x) or polyvinyl alcohol (1x). Renal function was monitored with creatinine levels. Tumour size was controlled every three months by means of sonography.
Results:
Technical success rate was 100%. In 3/3 patients haematuria could be stopped. Post-embolisation renal function was unchanged in 6 patients and deteriorated in two patients; creatinine level rose to a maximum of 2.2 mg%. We observed no other side effects. Seven of eight patients died during a median follow-up period of 9.3 months (4-18 months); in two cases they died due to their underlying malignant disease. One patient had local tumour progress.
Conclusions:
Superselective embolisation of renal tumours in patients with solitary kidneys may be a helpful, well-tolerated therapeutic option in inoperable, symptomatic patients.
