Abstract

To compare the therapeutic efficacy of conventional laparoscopic pyeloplasty (LP) and robot-assisted single-port laparoscopic pyeloplasty (RSLP) for ureteropelvic junction obstruction (UPJO) in infants and to summarize the preliminary experience and advantage of RSLP. The clinical data of UPJO infants (≤ 12 months) who received LP and RSLP in our center from October 2018 to October 2024 were analyzed retrospectively. A total of 51 patients with UPJO were included, with 11 cases receiving RSLP (8 with left UPJO; 3 with right UPJO) and 40 receiving LP (29 with left UPJO; 11 with right UPJO). In the RSLP group, the median age was 3 months (range: 1-9 months). In the LP group, the median age was 2.5 months (range: 1-11 months). The mean operative time was 217.45 ± 20.77 min for the RSLP group and 258.57 ± 52.56 min for the LP group. The mean time of ureteropelvic anastomosis in the RSLP group was shorter than that in the LP group (79.36 ± 17.74 vs. 99.35 ± 21.03). The mean hospital stay was 6.27 ± 2.53 days for the RSLP group and 6.32 ± 2.71 days for the LP group. The mean postoperative hospital stay was 1.9 ± 0.94 days for the RSLP group and 2.67 ± 2.37 days for the LP group. The mean hospital costs were 57,950.63 ± 1,165.68 yuan for the RSLP group and 30,396.30 ± 5214.06 yuan for the LP group. Significant improvements in the hydronephrosis grading, anterior-posterior renal pelvic diameters, and renal parenchymal thickness were observed in both groups after surgery. RSLP is a safe and effective method for the treatment of UPJO in infants. Compared with LP, RSLP has the advantages of precise suturing, short anastomosis time, and short operation duration, making it an attractive and safe option. However, it faces the disadvantages of higher cost of hospitalization.
