Abstract :
Objective: To compare the efficiency and security of the balloon dilators versus fascial dilators in
percutaneous nephrolithotripsy (PCNL), We compared the difference of intraoperative and postoperative
parameters of patients using these two different methods of expansion and having no significant statistic
differences in peroperative parameters.
Methods: This is a retrospective analysis of 134 patients undergoing PCNL with upper urinary calculi from
January 2012 to January 2014 in Luoyang Central Hospital affiliated to Zhengzhou University. These patients
meeting the inclusion criteria were divided into two groups: the group of balloon dilators (group A) and
the group of fascial dilators (group B). Two groups were compared for success rate of first expansion,
clearance of stone, duration of surgery, intraoperative hemorrhage, blood transfusion rate, postoperative
hospitalization and the incidence of complications.
Result: In Group A, a total of 91 patients (51 men and 40 women, mean age 51.22±8.96 years, ranged from
28 to 68 years, the calculi maximum diameter from 0.9 to 4.5cm, 28 cases with a history of gravel, mean
Body mass index 24.20±2.34, 73 cases with hydronephrosis and 26 cases with underlying diseases such as
hypertension, diabetes and the like) undergoing PCNL were retrospectively reviewed. Similarly, In Group
B, a total of 43 patients (28 men and 15 women, mean age 49.64±10.62 years, ranged from 15 to 70 years,
the calculi maximum diameter from 1.1 to 5.2cm, 18 cases with a history of gravel, mean Body mass index
24.40±2.70, 38 cases with hydronephrosis and 14 cases with underlying diseases such as hypertension,
diabetes and the like) undergoing PCNL were retrospectively reviewed. Our results showed that there
was a statistically significant better outcome in Group A than in Group B in terms of success rate of
first exploration, duration of operation, intraoperative hemorrhage, postoperative hospitalization and the
incidence of complications. Additionally, there was no statistically significant difference with respect to
clearance of stone and incidence of blood transfusion in the two groups.
Conclusion: Balloon dilators had shorter operation time, less bleeding, higher success rate of first expansion,
less postoperative complications and shorter postoperative hospitalization than fascial dilators in PCNL.
