Objective:
To evaluate the feasibility and effectiveness of robot-assisted laparoendoscopic single-port surgery (R-LESS) in infant urology and to report our early single-center experience.
Methods:
Clinical data were retrospectively collected from 20 infants (≤ 12 months) who underwent R-LESS using the Da Vinci Xi system between February 2024 and April 2025. Information included demographic characteristics, perioperative parameters, and postoperative outcomes. The median age at surgery was 2.5 (IQR: 2, 4) months. Sixteen patients underwent pyeloplasty, two underwent ureteral reimplantation, and two underwent nephrectomy.
Results:
All procedures were completed successfully without conversion to open surgery or intraoperative complications. The median docking time, console time, and total operative time were 7 (IQR: 6, 8) min, 181 (IQR: 156, 207) min, and 212 (IQR: 189, 238) min, respectively. Median estimated blood loss was 5 (IQR: 5, 9) mL. Median total hospital stay was 6 (IQR: 6, 10) days, with a median postoperative stay of 2 (IQR: 1, 4) days. The median follow-up duration was 9.1 (IQR: 5.4, 11.2) months. Postoperative complications were observed in three cases (15%): two patients (10%) developed febrile urinary tract infections (Clavien-Dindo Grade II), which resolved with antibiotic treatment; one patient (5%) required hospital readmission for wound debridement due to poor healing (Clavien-Dindo Grade III), with favorable postoperative recovery.
Conclusion:
R-LESS is a safe and effective minimally invasive surgical approach in infant urology.
