Primary pyeloplasty for uretero-pelvic obstruction in the USA adult population with or without double-J indwelling ureteral stents. Insurance claims data on contemporary time to removal trends, perioperative complications, health care costs, and re-intervention rates

Using a large population-based dataset, we primarily sought to compare postoperative complications, health-care expenditures, and re-intervention rates between patients diagnosed with ureteropelvic junction obstruction (UPJO) undergoing stented vs. non-stented pyeloplasty. The secondary objective was to investigate factors that influence the timing of DJ stent removal.
