Despite the ambiguity and equal weight of guidelines for shockwave lithotripsy and ureteroscopy, ureteroscopy is the most common treatment for kidney and ureteral stones in children and adolescents. Thus, to assess stone clearance and patient-reported outcomes following ureteroscopy or shockwave lithotripsy, this study was carried out in children and adolescents.
The patients were recruited for this nonrandomized clinical research at 31 US and Canadian medical facilities between March 16, 2020, and July 31, 2023. The patients with ureteral stones, kidney stones, or both who were between the ages of 8 and 21 were included. The last day of follow-up was October 15, 2023.
6 (±2) weeks following surgery, the main result was the stone removal measured by standardized ultrasonography. Stone clearance was assessed per kidney or ureter using logistic regression, and estimated stone clearance rates were produced for each operation using inverse probability weighting and random intercepts each location.
A total of 1,142 patients (690 females [60.4%]) with a median age of 15.6 years (IQR, 12.6-17.3 years) were included in this research. Regarding race and ethnicity, 884 patients (77.4%) were White, 130 patients (11.4%) were Hispanic, and 41 patients (3.6%) were Black.
A median stone size of 6.0 mm (IQR, 4.0-9.0 mm) was found in 1069 kidneys or ureters treated by 124 urologists using ureteroscopy and shockwave lithotripsy (n = 953 and 189 patients), respectively.
Almost, 841 operations for 767 patients (80.4%) undergoing ureteroscopy and 6 procedures for 5 patients (2.6%) undergoing shockwave lithotripsy involved the placement of ureteral stents at the time of index surgery.
In 105 patients who had shockwave lithotripsy (67.5% [95% CI, 61.0%-74.1%]) and 474 patients who had ureteroscopy (71.2% [95% CI, 63.8%-78.5%]), stone removal was achieved; however, this difference was not statistically significant (risk difference, 3.6% [95% CI, −6.2% to 13.5%]).
One week following surgery, ureteroscopy caused more urinary symptoms (symptom score difference, 3.9 [95% CI, 1.2-6.7]) and discomfort interference (T-score difference, 5.0 [95% CI, 2.3-7.8]) than shockwave lithotripsy.
In the week after surgery, ureteroscopy patients missed more coursework (risk difference: 21.3% [95% CI: 9.7%-32.8%]) and caregivers missed more work (risk difference: 23.0% [95% CI: 11.0%-35.0%]). Overall, improved patient-reported outcomes were linked to shockwave lithotripsy.
