To evaluate the applicability of contemporary percutaneous nephrolithotomy (PCNL) scoring systems in pediatric patients and to compare their predictive power for postoperative outcomes.
The records of 125 pediatric patients who were diagnosed with renal calculi and managed with PCNL between March 2011 and April 2016 were retrospectively analyzed. The predictive scoring systems; The Guy's Stone Score (GSS), S.T.O.N.E. nephrolithometry and, Clinical Research Office of the Endourological Society (CROES) were calculated for all patients included in the study. Patient demographics, stone free rate (SFR), and complications were all reported and analyzed.
In patients with residual stones (group I) vs those who were (group II) stone free the median (IQR) of GSS was 2 (2-3) and 2 (1-2), CROES nomogram score was 215 (210-235) and 257 (240-264), and S.T.O.N.E. nephrolithometry score was 8 (7-9) and 5 (5-6), respectively (each p<0.0001). S.T.O.N.E. nephrolithometry score revealed the highest accuracy in predicting SFR. GSS was significantly correlated with complications but the CROES nomogram and S.T.O.N.E nephrolithometry were not significantly correlated with complications.
The scoring systems could be used in predicting PCNL success in pediatric setting. However, further studies are required to make modifications in the scoring systems in pediatrics. The main variables in the scoring systems as stone burden, tract length and case volume were measured using records from adult patients. Besides these variables, the relatively small pelvicalyceal system and the higher incidence of anatomic malformations in pediatrics could potentially affect PCNL outcomes.
This research output has an Altmetric Attention Score of 9. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 01 January 2021.
All research outputs
#6,059,705
of 34,350,842 outputs
Outputs from The Journal of Urology
#4,227
of 21,939 outputs
Outputs of similar age
#74,971
of 354,407 outputs
Outputs of similar age from The Journal of Urology
#100
of 515 outputs
Altmetric has tracked 34,350,842 research outputs across all sources so far. Compared to these this one has done well and is in the 82nd percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 21,939 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 9.7. This one has done well, scoring higher than 79% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 354,407 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 78% of its contemporaries.
We're also able to compare this research output to 515 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 80% of its contemporaries.
