Comparison of Surgical Outcomes Between MPCNL and RIRS

Comparison of Surgical Outcomes in the Treatment of Renal Stones Larger Than 1 Centimeters Between MPCNL and RIRS: a Single-center, Randomized, Prospective Study

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.

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.

Inclusion Criteria:

• The person who has been diagnosed with renal stone larger than 1cm renal and who has been supposed to undergo MPCNL or RIRS.
• The person who signed up for participation and agree with intention of clinical test.

Exclusion Criteria:

• The patient whose medical record has been omitted from database.
• The patient who has an anatomical abnormality of urinary tract and/or metabolic illness
• The patient who do not agree with the intention of the clinical study.
