Purpose: Simple nephrectomy is technically demanding in patients with recur
rent inflammation or bleeding. It is also unwise to subject patients in poo
r health to the rigors of an extensive operative procedure. We report our e
xperience with complete renal embolization as a safe and reliable alternati
ve to surgical nephrectomy.
Materials and Methods: Eight patients underwent complete renal embolization
as an alternative to nephrectomy. Patients were given antibiotics intraven
ously before and after embolization. Six patients with indwelling nephrosto
my tubes received post-embolization instillation of 80 mg. gentamicin befor
e tube removal. Narcotic analgesics were also given as needed for pain cont
rol. Post-embolization hospital course was noted.
Results: The indications for embolization included hydronephrotic, poorly f
unctioning kidneys with pain in 5 cases, and recurrent bleeding from angiom
yolipoma, bleeding after percutaneous resection of renal pelvic transitiona
l cell carcinoma with metastases and spontaneous renal bleeding after hemod
ialysis in 1 each. Embolization was successful in 4 men and 4 women with a
mean age of 58.8 years. In 6 patients severe flank pain required narcotic a
nalgesics. One patient complained of nausea, 6 had fever and 6 had leukocyt
osis. In I case thrombosis of a limb of an aortobifemoral bypass graft requ
ired thrombectomy. Median hospital stay was 2.5 days. At a mean followup of
30.6 months presenting symptoms had resolved in all cases without hyperten
sion, renal failure or abscess.
Conclusions: Complete renal embolization is a viable alternative to nephrec
tomy in patients with poorly functioning kidneys who present with pain or b
leeding and in those who are poor operative candidates. This procedure is s
afe, reliable and minimally invasive with few long-term sequelae, and it is
well tolerated.
