Introduction & Objective :

The aim of this study was to retrospectively analyze outcomes of flexible ureteroscopy and laser fragmentation (FURSL) of renal stones with the use of ureteral access sheath (UAS) in the paediatric population.


Methods :

We retrospectively collected data between January 2011 and January 2018 for patient demographics, stone characteristics and outcomes in 21 children who underwent FURSL with the use of UAS.


Results :

Twenty-one patients (10 boys and 11 girls) with a mean age of 11.8 years (range 2-16 years) underwent FURSL using an access sheath. The stone location was in the lower pole in 13 patients (62 %) with 12 patients (57%) having multiple stones. A 9.5F (35 cm) Cook Flexor Ureteral Access Sheath was used in all cases. The individual largest and cumulative mean stone diameter was 30mm (range 5 -30mm) and 15.4 mm (range 5-35mm) respectively. Post-operative stent or overnight ureteric catheter was inserted in 14 patients (67%).


Forty-three procedures (average: 2/patient) were needed to achieve a stone free rate (SFR) of 95%. There were no procedural or long-term complications noted over a median follow-up of 26 months (4-37 months).


Conclusions :

Use of a UAS for FURSL in the paediatric population is safe and feasible with good outcomes and without any long-term sequelae.
