Single-port robot-assisted laparoscopic pyeloplasty in an infant: A video case report with 9 months follow up

Single-port robot-assisted laparoscopic surgery is a breakthrough in the field of minimally invasive surgery. However, it is currently only applicable to older children due to the limitation of operating space. Here, we report a case of single-port robot-assisted laparoscopic pyeloplasty (RALP) using the da Vinci Xi® surgical system in a 7-months infant.A 7-month-old infant with ureteropelvic junction obstruction (UPJO) underwent single-port RALP conducted using the da Vinci Xi® System. Retrospective perioperative, immediate postoperative outcomes and 9 months follow up were investigated.Surgery progressed smoothly without additional operative port placement or open procedure. The total operative time was 160 min, including 90 min of console time. And estimated blood loss was 5 ml. No intraoperative and postoperative complications were found. Postoperative follow-up showed good efficacy, and the incision seemed to be traceless.Single-port RALP using da Vinci Xi® System in infants is feasible and safe. It showed excellent efficacy in treating UPJO as shown in the short-term follow-up. Subsequent cohorts with more infant patients and long-term follow-up will be required to further validation.
