The least invasive microperc with an optical puncture system appears to be a safe and effective treatment modality in patients with different kinds of stone disease with respect to various features. Although the initial cases were patients with single stones of less than 20 mm, the combined use of this system with other minimally invasive treatment modalities for the management of larger stones is promising.

Percutaneous nephrolithotomy (PCNL) is one of the most common treatment options in the management of kidney stones in children. While colon perforation during PCNL is reported as a rare complication in adults, there are scarce data regarding colon perforation during pediatric PCNL. We report the successful management of colon perforation occurring during PCNL and of a renal stone in a 6-year-old child. Moreover, we describe the procedure to be followed for colon perforation in children.
