[Reconstruction of intraoperative ureteral injury].

Intraoperative injuries of the upper urinary tract are seldom and mostly found in the prevesical segment of the ureter. The immediate plastic reconstruction by reanastomosis or regeneration shows positive results. Depending on the localization of the ureter trauma, ureterocystoneostomy, end to end anastomosis, or pyeloureteroneostomy are the most successful reconstruction methods.
