Abstract titles should be brief and reflect the content of the abstract.
Patients with autosomal dominant polycystic kidney disease (ADPKD) have bilateral multiple progressively enlarging renal cysts. These cysts can cause renal tissue and adjacent organs compression, resulting in abdominal distention, pain, constipation, poor appetite, malnutrition, dyspnea and refractory hypertension. They may also bring about inadequate space for the graft kidney in kidney transplantation. Transcatheter arterial embolization (TAE) of renal arteries may effectively and safely reduce kidney size.
This is a retrospective observational study. Our subjects are patients with ADPKD who have undergone unilateral or bilateral renal artery TAE in Taiwan. Basic demographic characteristics and laboratory data were recorded. Imaging studies (computed tomography or magnetic resonance image) were performed before and after TAE to assess kidney volume which was measured based on the ellipsoid equation (π/6xLxWxD). We then calculated the volume reduction ratio per month of each kidney. The secondary outcomes include relief in symptoms and complications (such as abdominal pain and fever) after TAE.
Between 2019/09 and 2025/04, 13 TAE procedures with follow-up data were collected from 13 kidneys in 10 patients. Six patients (60%) were male, and 4 patients (40%) were female. The median age at the time of TAE was 48 years. Symptoms before TAE included abdominal distention, gross hematuria, and repeated urinary tract infection. Four patients received TAE in the purpose of creating more space before renal transplantation, and all of them could receive subsequent renal transplantation. Six patients received TAE due to abdominal distention or repeated infection. The median volume reduction ratio per month of each kidney was 14.9%. All recorded symptoms improved after TAE. The most common complication of TAE was abdominal pain, followed by fever. There was no mortality case.
TAE of renal arteries in selected ADPKD patients with end-stage renal disease by experienced radiologists is safe and effective in reducing renal size and relieving symptoms. Moreover, compared to traditional nephrectomy, TAE is a less invasive option to create more space for subsequent successful kidney transplantation.
