Multicenter Quantification of Radiation Exposure and Associated Risks for Prostatic Artery Embolization in 1476 Patients.

Background Prostatic artery embolization (PAE) is a safe, minimally invasive angiographic procedure that effectively treats benign prostatic hyperplasia; however, PAE-related patient radiation exposure and associated risks are not completely understood. Purpose To quantify radiation dose and assess radiation-related adverse events in patients who underwent PAE at multiple centers. Materials and Methods This retrospective study included patients undergoing PAE for any indication performed by experienced operators at 10 high-volume international centers from January 2014 to May 2021.

Operator Learning Curve for Prostatic Artery Embolization and Its Impact on Outcomes in 296 Patients.

Purpose: To define operator learning curve inflection points for prostatic artery embolization (PAE) and their impact on technical efficiency, clinical outcomes, and adverse events.

Materials And Methods: Between May 2013 and May 2021, 296 consecutive patients with moderate-to-severe lower urinary tract symptoms, urinary retention, or gross hematuria from benign prostatic hyperplasia underwent PAE by an interventional radiologist without prior PAE-specific experience. Operator learning curves plotted procedure time, fluoroscopy time, contrast volume, and embolic endpoint data against sequential procedure number.

Page kidney: an unusual complication of image-guided native renal parenchymal biopsy - case report and literature review.

Page kidney is a pathologic phenomenon in which extrinsic compression of renal parenchyma from a subcapsular collection causes secondary systemic hypertension, via activation of the renin-angiotensin-aldosterone system. Following the first description of Page kidney, the condition was most often recognized following blunt trauma to the flank. Increasingly, non-traumatic and iatrogenic etiologies of Page kidney have been described.
