Outcome of Mini-Percutaneous Nephrolithotomy for Renal Stones in Infants and Preschool Children: A Prospective study

To assess safety and efficacy of Miniperc for renal stones in preschool age patients. To the best of our knowledge, this may be the first prospective study on this subject. Reports on Miniperc are still few.

Most of them are retrospective and used sheath size of ≥18Fr which is still relatively large for young children.

From January 2012 to May 2013, Miniperc was performed for 26children (≤6years old) with renal calculi

primary-SFR, SFR after second-look Miniperc and after subsequent ESWL were 77%, 85% and 92%, respectively. Retreatment rate was 8%. Auxiliary ESWL was done in 11%. One (4%) case had 3mm clinically insignificant residual fragment. Complications were bleeding (8%), hematuria and blood transfusion (4%), renal pelvis perforation (4%), leakage (8%) and fever (15%). No patient developed hypothermia. Operative time was significantly prolonged in multiple (>2) stones (p=0. 006), calyceal stones (p=0. 002) or stone size ≥30mm (p=0. 022). SFR was significantly lower in children with >2stones (p=0. 028) and increased stone size ≥30mm (p=0. 014).

Miniperc is safe and effective minimally invasive procedure for pediatric renal stones using 14Fr access sheath. SFR was significantly lower in children with >2 stones or increased stone size ≥30mm. This was overcome by second-look treatment and auxiliary ESWL.
