Practice patterns and outcomes of pediatric partial nephrectomy in the United States: Comparison between pediatric urology and general pediatric surgery

While most partial nephrectomies in the United States are performed by PUROs, GPSs perform the majority of surgeries for malignancy. There is no difference in LOS or complication rate undergoing nephron-sparing surgery for malignant disease; however, PUROs had a shorter LOS and lower complication rate when operating for benign diseases.Table.
