[ULTRASOUND GUIDED PERCUTANEOUS SCLEROTHERAPY OF SIMPLE RENAL CYSTS: PRIMARY SUCCESS AND PROCEDURE SAFETY].

OBJECTIVE

To evaluate primary (technical) success and procedure safety in ultrasound (US)-guided percutaneous sclerotherapy of simple renal cysts, using 96% ethanol.

PATIENTS: 17 patients with symptomatic simple renal cysts referred by nephrologists or urologists.

METHODS

US-guided percutaneous puncture of the cyst with an 18G (gauge) needle and a "pigtail" 5F (French) catheter, drainage and inspection of the cyst content, and injection of ethanol.

RESULTS

Puncture was rejected in two referred patients because of Bosniak II cyst and renal hilum proximity. 15 patients underwent puncture and drainage of the cyst content. In 4 patients ethanol was not injected because: thick or bloody cyst, proximity of renal hilum and severe pain during injection of ethanol. 11 patients underwent sclerotherapy of the cyst. The average size of sclerosed cyst was 8 cm (range 6-12 cm). There were no significant complications.

CONCLUSION

US-guided percutaneous sclerotherapy of simple renal cysts is easy to perform and safe procedure, with the previous good selection of cysts that are suitable for the sclerotherapy.
