Malfunction endostapler trapped on renal vein - Nightmare scenario for surgeon.

The utilization of endostapler devices has become standard practice for renal vein ligation during laparoscopic nephroureterectomy. While exceptionally rare, malfunctions can occur in these devices. In the video, we present a malfunctioning endostapler that became trapped on the renal vein. Fortunately, this catastrophic event was successfully managed without conversion to open surgery or massive blood loss and was recorded on video. We propose a structured management flow chart for addressing GIA malfunction, aiming to assist surgeons in navigating through this potentially life-threatening situation.
