Infant robot-assisted laparoscopic upper urinary tract reconstructive surgery.

OBJECTIVE: Our aim was to assess the outcomes of infant robot-assisted laparoscopic (RAL) upper urinary tract reconstruction.

MATERIALS AND METHODS: The medical records of all infants who underwent RAL upper urinary tract reconstruction were reviewed. Patients less than 1 year of age at surgery were included. Patient demographics, intraoperative details, narcotic usage, and complications were reviewed.

RESULTS: Ten infants met the study criteria. There were five right and five left-sided procedures. Eight pyeloplasties (4 right, 4 left) and two ureteroureterostomies (1 right single system, 1 left duplex system) were performed. The median age was 8 months (range 3-12 months). Median weight was 7.7 kg (range 5.8-10.9 kg). Median operative time was 128 min (range 95-205 min). There was no significant blood loss or intraoperative complications. One (10%) patient received a regional block. Eight (80%) patients did not receive postoperative narcotics. Median hospital stay was 1 day (range 1-2). Median follow-up was 10 months (range 3-18 months). Complications included one urinary leak, one ileus, and one urinary tract infection. Hydronephrosis improved in all patients.

CONCLUSIONS: Infant RAL upper urinary tract reconstruction is technically feasible, safe, and effective. It can be applied for duplication anomalies and single system obstructions in infants.
