Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of this research is to investigate the surgical outcomes of minimally invasive percutaneous nephrolithotomy(MPCNL) and retrograde intrarenal surgery (RIRS)for patients with renal stone larger than 1cm.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

It is pointed out that there is the disadvantage of conventional PCNL technique which showed dramatic decrease in Hb and renal damage even though it has some advantages of a short operation time and a high stone-free rate. MPCNL and RIRS has recently been considered as very efficacious methods.
