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

Introduction: 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.

Methods: 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.

Results: 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.

Conclusion: 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.
