Abstract Objectives This study compared available aggregate perioperative outcomes and estimated length-of-stay-related cost savings between robot-assisted, open, and laparoscopic pyeloplasty in paediatric patients in an initial Slovak single-surgeon experience. Background Pyeloplasty is an established reconstructive treatment for ureteropelvic junction obstruction in children. Robot-assisted surgery may facilitate intracorporeal suturing; however, institutional interpretation requires cautious assessment of clinical outcomes, local resource use, and cost assumptions. Methods This retrospective aggregate-data comparative analysis used surgeon-provided data from paediatric patients treated at the Department of Paediatric Urology between September 2025 and May 2026. Each group included 12 patients undergoing open, laparoscopic, or robot-assisted pyeloplasty. Available outcomes were mean length of hospital stay, mean operative time, conversion rate, anastomotic leak, assisting personnel, second postoperative clinic visit, and estimated bed-day-related savings. No inferential statistics were calculated. Results Robot-assisted pyeloplasty had a mean hospital stay of 4.58 days, compared with 9.17 days for open pyeloplasty and 6.17 days for laparoscopic pyeloplasty. Mean operative time was 110.5, 106.9, and 115.2 min, respectively. Using an institutional bed-day cost of €650 for accommodation at the Department of Paediatric Urology, excluding medication costs, estimated savings were €2984 per robot-assisted procedure compared with open pyeloplasty and €1034 compared with laparoscopic pyeloplasty. Conclusion These initial Slovak paediatric aggregate data are descriptive and require cautious interpretation because the dataset was small, unmatched, and lacked patient-level baseline variables, event counts, and comprehensive cost data.
