povidone-iodine and Kidney-Diseases--Cystic

To evaluate the efficacy of povidone-iodine sclerotherapy after percutaneous drainage of simple renal cysts in the treatment of symptomatic patients.. Sixteen patients with symptomatic renal cysts were treated by percutaneous drainage and injection of povidone-iodine solution. The cysts were drained by a nephrostomy tube catheter, and povidone- iodine injections were repeated every 24 hours for 3 days. All patients were followed up by ultrasound examination during a period ranging from 1 to 4 years (mean 1.8 years).. Thirteen patients experienced recurrence of cysts, while complete resolution was observed in only three patients. Of the cysts that recurred, only partial resolution in cyst diameter was observed (from 3-10.5 cm to 2.4-8.6 cm). During the follow-up period, 12 of the 16 patients (75%) continued to have pain that necessitated additional treatments.. Povidone-iodine sclerotherapy is followed by a high rate of recurrence and is therefore not indicated for the treatment of symptomatic simple renal cysts.

Symptomatic renal cysts can be treated with percutaneous sclerosis using ordinary povidone-iodine solution. We describe our methods and outcomes in 5 patients so treated.

A 48-year-old man was admitted to our hospital because of high fever and left flank pain. Laboratory findings revealed a high white blood cell count, high C-reactive protein level, and severe pyuria. Sonographic examination revealed an enlargement of the cyst at the upper pole of the left kidney that had already been detected. Percutaneous drainage was performed for the cyst and 60 ml of purulent fluid was obtained. Bacterial culture of the fluid was positive for Propionibacterium acnes and gamma-Streptococcus. The drainage and administration of povidone-iodine was continued for 7 days. The size of the cyst was reduced with disappearance of symptoms.

Percutaneous puncture followed by instillation with 10% povidone iodine was performed on 23 patients with benign renal cysts. All patients showed remarkable reduction (mean: 86.6%) in size of renal cyst on sonography or computed tomography within a short time (mean: 143 days). Twelve (85.7%) of the 14 symptomatic patients due to the disease were relieved of subjective symptoms such as lumbago after instillation. In a 71 year-old man, microscopic hematuria disappeared after this treatment. There were no complications with this treatment except in one patient who suffered from perinephritis due to a technical problem. This treatment seems to be a safe and effective way to prevent recurrence of cystic fluid.
