Long-term results of extended Boari flap technique for management of complete ureteral avulsion: A case report

Figure 1 Preoperative computed tomography. A: Computed tomography (CT) urography three-dimensional reconstruction showed retroperitoneal contrast extravasation with the most severe site in the ureteropelvic junction (UPJ) region; B: Enhanced CT showed left ureteral disruption just below the UPJ (white arrow).

Figure 2 The completely avulsed ureter. A: A long isolated devitalized ureter was noticed within the bladder intraoperatively; B: The full-length avulsed ureter in vitro.

Figure 3 Ureteral reconstruction with an extended Boari flap intraoperatively. The white arrow shows a tension-free anastomosis.

Figure 4 Postoperative computed tomography urography. A and B: Computed tomography urography three-dimensional reconstruction at 14 d (A) and 2 mo postoperatively. Note that bladder volume is visibly larger at 2 mo postoperatively.
