MPCNL Study

Details and patient eligibility

About

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.

Full description

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.

Enrollment: 70 patients

Sex: All

Ages: 20+ years old

Volunteers: No Healthy Volunteers

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.

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

70 participants in 2 patient groups

RIRS (retrograde intrarenal surgery)

Active Comparator group

Description:

Use of flexible ureteroscopy to access and remove renal stones without percutaneous nephrostomy tract

Treatment:

Device: RIRS

MPCNL (mini-perc)

Experimental group

Description:

A new technique that reduced the size of percutaneous tract to make renal stone into small pieces. Patients will be randomized and assigned to each group at the ratio 1:1

Treatment:

Device: MPCNL
