Transcatheter arterial embolization using absolute ethanol is an effective treatment for renal tumors. This procedure is valuable for preoperative intervention and managing inoperable or symptomatic cases, offering a vital therapeutic option.

Area of Science:

  • Interventional Radiology
  • Nephrology
  • Oncology

Background:

  • Renal tumors, including hypernephroma and angiomyolipoma, present therapeutic challenges.
  • Surgical intervention may not always be feasible or optimal for all renal tumor cases.

Purpose of the Study:

  • To evaluate the efficacy and application of transcatheter renal infarction using absolute ethanol for renal tumors.
  • To assess its role in preoperative management and as a primary or palliative therapy.

Main Methods:

  • Twenty renal infarction procedures were performed on 18 renal tumors in 17 patients using absolute ethanol.
  • Techniques included balloon occlusion catheter and superselective administration.
  • Average 15ml of absolute ethanol was injected at 1-2 ml/sec.

Main Results:

  • The study included 15 hypernephroma and 2 angiomyolipoma cases.
  • Indications varied: preoperative embolization (8 hypernephroma), primary therapy/palliation (7 hypernephroma, 2 angiomyolipoma).
  • Long-term survival benefits were not definitively confirmed.

Conclusions:

  • Transcatheter embolization with absolute ethanol is a suggested indispensable treatment for renal tumors.
  • It is particularly valuable in preoperative, inoperable, or symptomatic renal tumor cases.
  • This technique offers a significant therapeutic option in managing complex renal pathologies.
