MATERIAL AND METHODS
we retrospectively reviewed the prospectively collected data of 215 renal units who underwent
PCNL in our department from November 2014 to September 2016.Patient’s data including age,
gender, stone burden, hemoglobin drop, operative time,radiation dose, pain score, complications
and hospital stay duration were documented. Successful outcome was a stone free renal unit on
postoperative USG KUB. Statistical analysis was done on SPSS 20 by using independent sample
t-test and chi-square test.
RESULTS
In this study, 215 PCNLs were divided into five different age groups i.e. 35 in Group (0-3) years
of age, 40(3-6) , 68 (6-11), 44 (11-16) and 28 (16-20) years of age. The overall mean age was
8.46±5.34. Significant difference was found between groups regarding operative time (p=0.003),
on the other hand hemoglobin and hematocrit drop found to be non-significant p=0.807 and
p=0.697 respectively. Similarly, statistically nonsignificant difference was found in complications
including pleural effusion p=0.325 and fever (p=0.810). The overall mean stone burden was
2.89±2.06 with 95% C.I. (2.61 - 3.17). The overall stone free rate was 86.50%. It is pertinent to
mention here that by comparing the combined first two age groups (0 - 6 yrs.) with the other three
combined age groups (6-20yrs.) the stone free rate for the younger age group was 98.8% while for
the older group it was 77% which was statistically highly significant p value 0.0001.
CONCLUSIONS
PCNL is a more efficient and safe procedure for the infants and toddlers than for the older age
groups of children.

PURPOSE
To evaluate the safety and outcome of Mini PCNL in paediatric age group.
MATERIAL AND METHODS
Records of 135 children with 153 RU who underwent mini PCNL with 14 Fr amplatz sheath from
January to September 2016 were retrospectively reviewed for age,gender,stone location,stone
burden,approach,disintegration technology (pneumatic lithoclast and high power holmium YAG
laser), stone clearance, operative time, blood transfusion and complications.
RESULTS
Renal units were calssified into two groups. Group A (simple):single stone n=70, (Renal Pelvis=45,
calyces=25). Group B(complex):multiple stones n=83 (Renal pelvis stone with one or more calyceal
stones).
The mean age and gender were comparable in two groups; 5.3 +/-3.3 vs 6.0+/-3.8 years(p=0.19)
and 2.3:1vs 1.6:1 (p=0.26) respectively.Stone burden in GroupAwas 1.5 +/-0.85 vs 2.23+/- 1.11 cm
2
in Group B (p <0.0001).Stone clearance in Group A and B was 93% vs 77% respectively(p= 0.008).
Mean operative time was 95.7+/-39 in Group A vs 117+/-41 min in Group B (p=0.001). Blood trans-
fusion in group A was 9%(6/70) vs 17%(14/83) in Group B (p=0.12). Approach was supracostal in
40% of Group A vs 50% in Group B.
