Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older with a clinical diagnosis of ADPKD or ADPLD and significant compressive symptoms from large cysts.

Probably not a fit

Patients with multiple large cysts or those whose largest cysts are below the specified size criteria may not benefit from this study.

What this trial studies

This observational study aims to evaluate the impact of foam sclerotherapy on large kidney and liver cysts in patients with autosomal dominant polycystic kidney disease (ADPKD) and autosomal dominant polycystic liver disease (ADPLD). It will assess changes in cyst volumes and quality of life outcomes over a follow-up period of up to 12 months. The study will utilize a patient-reported outcome tool specifically designed for polycystic liver disease to gather relevant data. By focusing on patients with significant cyst burden, the study seeks to provide insights into the effectiveness of this treatment approach.

Why it matters

Potential benefit: If successful, this study could improve the quality of life for patients suffering from large cysts associated with ADPKD and ADPLD.

How similar studies have gone: While foam sclerotherapy has been used for other conditions, this specific application for ADPKD and ADPLD is relatively novel and has not been extensively tested in prior studies.
