Inguinal hernias are common conditions in general surgery . Laparoscopic approach, whether transabdominal preperitoneal (TAPP) or totally extraperitoneal (TEP), is favored for its lower rate of surgical site infection, shorter hospital stay, and faster return to daily activities . Complications still occur, albeit in a small percentage, but can prolong hospital stay or be fatal . We present a case of a 55-year-old male patient who underwent TAPP procedure with proposed iatrogenic testicular artery injury resulting in a bilateral retroperitoneal hematoma . The treatment was conservative, and the patient was discharged in good general condition after 13 days . Six months postoperatively, no signs of hernia recurrence were observed . According to available literature, this is the first conservatively treated occult testicular artery injury during TAPP inguinal hernioplasty.
