Introduction:

PCNL has been established as a gold standard minimally invasive procedure for treatment of paediatric nephrolithiasis more than 20 mm. The aim of our study to compare the safety and efficacy of mini-percutaneous nephrolithotomy with laser lithotripsy in supine position vs prone position in treatment of paediatric renal stones.

Patient and methods:

At our outpatient clinic of Urology department at Minia university, Nephrology and Urology hospital ,There were 60 children attended , diagnosed as renal stone disease, fulfilled our criteria and included to our thesis .Patients were randomized by single blind technique into two groups: (Group 1) underwent mini PCNL in supine position (30) and (Group 2) underwent mini PCNL in prone position (30) .All patients were evaluated 1 month postoperatively by: plain X-ray KUB or CT KUB (if radiolucent stones ) for assessment of stone clearance .

Results

There were no statistically significant differences in access time, number of punctures, or stent type between the two groups. However, positioning time was significantly shorter for the supine group compared to the prone group. Additionally, the supine group had notably shorter operative and fluoroscopy times than the prone group.

Conclusion

Both mini PCNL in supine and prone positions are safe and effective in treatment of paediatric renal stones However, supine position relatively shorter operative time and fluoroscopy consumption.
