Safety of High-Dose 3% Sodium Tetradecyl Sulfate for Sclerotherapy of Renal Cysts in Patients with Autosomal Dominant Polycystic Kidney Disease

Abstract

This study assessed the safety profile of high-volume (>10 mL) 3% sodium tetradecyl sulfate (STS) sclerotherapy for the treatment of renal cysts in patients with autosomal dominant polycystic kidney disease. A total of 211 sclerotherapy treatments were performed in 169 patients over a 5-year period, with a comparison of 2 patient cohorts based on the STS volumes used. The first cohort (n = 112) received a high volume (greater than 10 mL) of STS, and the second cohort (n = 57) received a low volume (less than 10 mL). The minor adverse event rate for the cohorts was 14.5% and 9.6%, respectively (P = .310), with postprocedure pain being the most common event. One major adverse event occurred, for which the patient required hospitalization for infection after low-volume STS treatment. Doses of STS higher than those currently recommended by the Food and Drug Administration for intravascular use allow large renal cysts to be treated safely in the setting of autosomal dominant polycystic kidney disease.
