The stone location was in the ureter (26.6%), lower pole (35.4%), and renal pelvis (16.5%), with 22/81(27%) having multiple stones and 21/102 (20.5%) where a ureteral access sheath (UAS) was used. Thirty-five (34.7%) had stent in situ pre-operatively. The mean (± SEM) single and overall stone size was 9.2 mm (± 0.48, range 3–30 mm) and 11.5 mm (± 0.74, range 4–46 mm) respectively, with 22 (27.1%) having multiple stones. Of the 81 patients, 29 (35.8%) had comorbidities, with 26 (32%) having multiple comorbidities. Over the 8-year period between April 2010 and April 2018, 81 patients with a mean age of 8.8 years (range 18 months–16 years) and a male to female ratio 1:1.1 underwent 102 procedures (1.28 procedure/patient to be stone free). Complications were graded according to the Clavien–Dindo classification and recorded within 30 days post-procedure and readmissions within 90 days after the procedure were also captured. Stone size and stone-free rate (SFR) were routinely assessed using an ultrasound (USS) and/or plain KUB XR. Consecutive patients ≤ 16 years of age undergoing semi-rigid or flexible URS for stone disease were included. Methodsĭata were analysed retrospectively from a database maintained between April 2010 and May 2018.
Ureteroscopy for management of stone disease has increased worldwide and is now being done more commonly in the paediatric age group. To report the outcomes of paediatric ureteroscopy (URS) for stone disease from a specialist endourology centre in the UK.
