PURPOSE
To compare of 3 different scoring systems [Guy’s Stone Score (GSS), S.T.O.N.E. nephrolithometry
score system and Clinical Research Office of the Endourological Society (CROES) score] which
are used to predict complications and success of percutaneous nephrolithotomy (PCNL) in pediatric
population.
MATERIAL AND METHODS
The data of 401 renal units (345 patients) which underwent PCNL between 1997–2017 were
analyzed. A. Patient demographics, calculated scores for three scoring system, stone free rates,
bleeding and complications without bleeding were analyzed with Mann-Whitney and chi-square
test.
RESULTS
Male to female ratio was 236/165 and median age was 8 (1–16). For stone free patients and
the remainders, the median scores of GSS were 2 (1–4) and 2 (1–4), S.T.O.N.E scores were
5 (4–9) and 6 (4–9), CROES scores were 182 (50–290) and 160 (67–281), respectively (p=
0.001, p=0.012, p<0.001). For patients with and without complications, the median scores of GSS
were 2 (1–4) and 2 (1–4), S.T.O.N.E scores were 5 (4–9) and 6 (4–9), CROES scores were
240 (50–290) and 162 (67–280), respectively (p=0.009, p=0.792, p=0.004).
All three scoring systems were able to predict the success. However, the risk of bleeding was
predicted by only CROES system (p=0.013). S.T.O.N.E was not able to predict any kind of compli-
cations where CROES and Guy’s scores were able to predict overall complication risk.
CONCLUSIONS
These all three scoring systems those were developed in adult patients were found to be able to
predict the success also in pediatric group. GSS and CROES were found to be useful to predict
overall complication where CROES was the only system to predict bleeding risk. This difference
may be due to the described adult parameters and it would be better to modify the parameters for
children.
