[Role of polyvidone-iodine ablation in the management of symptomatic renal cysts].

OBJECTIVE

To assess prospectively the results of percutaneous sclerotherapy with povidone-iodine of symptomatic renal cysts in adults.

METHODS

Fifty two patients were included in this study from august 2004 to november 2006. The operative indication was: pain (41 cases), urinary tract compression (8 cases), and very large cyst (3 cases). The preoperative assessment (site and dimensions of the cyst) always included ultrasonography. CT scan, for morphological assessment, was performed in 39 cases.

RESULTS

The mean age of patients was 63 years (47-75 years). The mean diameter was 76 mm. The cysts were punctured in all the cases directly under local anaesthesia and guided by sonography. The procedure was very well tolerated in every case, with external drainage for 72 hours. Clinical regression was complete in 48 cases (92%), with total ultrasonographic disappearing of the cysts in 31 cases (60%) with a mean follow-up of 14 months (3-29 months).

CONCLUSION

Percutaneous sclerotherapy with povidone-iodine is a safe, effective and reproducible treatment of symptomatic renal cysts in adults.
