Critical Application of Adult Nephrolithometric Scoring Systems to Children Undergoing Mini-Percutaneous Nephrolithotomy

Current status of nomograms and scoring systems in paediatric endourology: A systematic review of literature

“…4 further studies were included as they externally validated the 2 scoring systems specific to SWL [13][14][15][16] . 3 adult endourology tools, all specific to PCNL, were identified as having been investigated in 11 studies using paediatric participants [5][6]9,[17][18][19][20][21][22][23][24][25][26][27] . These studies assessed 1 tool or multiple tools in comparison to each other.…”

“…A key difference is that it includes all the stones in the affected renal unit and not only the target stone. 10 Studies have subsequently investigated the efficacy of GSS in paediatric patients 9,[18][19][20][21][22][23][24][25][26] . 5 of these studies were comparative to other nomograms and a detailed discussion of these results is included further on in the paper 9,[21][22][23][24] .…”

The remaining 5 studies considered GSS independently [18][19][20][25][26] .…”

“…It also takes into consideration the surgical case volume and centres performing less than 10 PCNL procedures per year were excluded from the study. 5 studies have subsequently validated CROES in paediatric patients 9,[21][22][23][24] . On multivariate analysis, CROES was found to be an independent predictor of PCNL success in all 5 studies and it compared favourably when compared to other tools.…”

“…Its reliance on CT may also limit applicability to paediatric KSD management. 4 studies have so far examined S.T.O.N.E in J o u r n a l P r e -p r o o f -10paediatric patients 9,[23][24]27 . As with CROES, it has had promising results with regards to prediction of SFR when assessed in comparison to other nomograms.…”
