Comparison and Evaluation of Outcomes of Ureteroscopy and Stone Laser Fragmentation in Extremes of Age Groups (≤10 Years and ≥80 Years of Age): A Retrospective Comparative Analysis of over 15 Years from 2 Tertiary European Centres

Aim: To assess and compare the outcomes associated with ureteroscopy and laser fragmentation (URSL) for extremes of age group (<= 10 and >= 80 years). Methods: Retrospective consecutive data were collected from two European centres for all paediatric patients <= 10 undergoing URSL over a 15-year period (group 1). It was compared to consecutive data for all patients >= 80 years (group 2). Data were collected for patient demographics, stone characteristics, operative details, and clinical outcomes. Results: A total of 168 patients had 201 URSL procedures during this time (74 and 94 patients in groups 1 and 2 respectively). The mean age and stone sizes were 6.1 years and 85 years, and 9.7 mm and 13 mm for groups 1 and 2 respectively. While the SFR was slightly higher in group 2 (92.5% versus 87.8%, p = 0.301), post-operative stent rate was also significantly higher in the geriatric population (75.9% versus 41.2%, p = 0.0001). There was also no significant difference in pre-operative stenting (p = 0.886), ureteric access sheath use (UAS) (p = 0.220) and post-operative complications. Group 1 had an intervention rate of 1.3/patient as compared to 1.1/patient in group 2. The overall complications were 7.2% and 15.3% in groups 1 and 2 respectively (0.069), with 1 Clavien IV complication related to post-operative sepsis and brief ICU admission in group 2. Conclusion: The paediatric population had a marginally higher incidence of repeat procedure, but the overall SFR and complications were similar, and post-operative stent insertion rates were much better compared to geriatric patients. URSL is a safe procedure in the extremes of age groups with no difference in the overall outcomes between the two groups.

Automated summary

By comparing the outcomes of ureteroscopy and laser fragmentation (URSL) in extreme age groups (<= 10 and >= 80 years), it was found that although pediatric patients required more repeat procedures, the overall success rate and complication rate were similar to that of geriatric patients, and the use of post-operative stents was much better.
