Role of Urinary Biomarkers in the Postoperative Follow-up of Ureteropelvic Junction Obstruction: A Preliminary Report

While the role of urinary biomarkers in differentiating non-obstructive dilatation (NOD) from ureteropelvic junction obstruction (UPJO) has been documented, there are limited reports on their utility in post-operative follow-up. This study aimed to document the values of urinary biomarkers: carbohydrate antigen (CA 19-9), neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule (KIM-1) following pyeloplasty.
