Micropercutaneous nephrolithotomy (microperc) in a two-year-old with the 'all-seeing needle'.

This paper presents the use of the single-step micropercutaneous nephrolithotomy (microperc) procedure for the treatment of a 13-mm renal stone using a 4.85-Fr 'all-seeing needle' in a 2-year-old toddler. In the current literature to date, this is the youngest case. Moreover, the advantages and reliability of this technique in toddler renal stone treatment are also evaluated.
