Summary
Ethanol ablation effectively treated benign renal cysts, with only one recurrence in 34 cases. This minimally invasive procedure showed a safety profile comparable to diagnostic aspiration alone.
Area of Science:
- Urology
- Interventional Radiology
Background:
- Benign renal cysts are common, often asymptomatic, but can cause symptoms or complications.
- Sclerotherapy using ethanol is a potential treatment option for symptomatic renal cysts.
Purpose of the Study:
- To evaluate the efficacy and safety of 95% ethanol ablation for benign renal cysts.
Main Methods:
- Thirty-four benign renal cysts in 29 patients were treated with 95% ethanol injection.
- A 4.6 French pigtail catheter was used for ethanol delivery.
- Patients were followed with ultrasound for 3 to 30 months.
Main Results:
- One recurrence of a renal cyst was observed at three months post-treatment.
- Minor complications, including hematuria and temperature elevation, occurred at rates similar to diagnostic aspiration.
- No major complications were reported during the follow-up period.
Conclusions:
- Ethanol ablation is an effective and safe treatment for benign renal cysts.
- The complication rate is low and comparable to standard diagnostic procedures.
- Ultrasound monitoring is adequate for assessing treatment outcomes.
