The effect of renal localization on the fate of clinically insignificant residual fragments after retrograde intrarenal surgery: A prospective 1-year follow-up study.

Objectives: Even after a successful retrograde intrarenal surgery (RIRS), clinically insignificant residual fragments (CIRF) could not pass from the kidney. We aimed to find out the differences on the fate of CIRF according to being in the lower pole or other renal localizations.

Methods: 81 patients whose stones were fragmented completely by RIRS were subdivided into two groups as group 1 (lower pole with 41 patients) and group 2 (upper pole, midpole, and renal pelvis with 40 patients).

Efficacy of various laser devices on lithotripsy in retrograde intrarenal surgery used to treat 1-2 cm kidney stones: A prospective randomized study.

Aims: To compare the efficacy of different laser devices and power ranges on lithotripsy in retrograde intrarenal surgery (RIRS) for 1-2 cm kidney stones.

Methods: A total of 223 participants undergoing RIRS for 1-2 cm kidney stones at our clinic between January 2015 and January 2017 were recruited for this prospective study (NCT02451319). Two hundred and four participants included in our study were randomly allocated into either ≤20 W with 20 W laser device (group 1) or ≤20 W with 30 W laser device (group 2) or >20 W with 30 W laser device (group 3).

Comparison of the efficiency, safety and pain scores of holmium laser devices working with 20 watt and 30 watt using in retrograde intrarenal surgery: One center prospective study.

Objectives: Holmium:Yttrium Aluminum Garnet laser lithotripsy is used in Retrograde Intrarenal Surgery. Fragmentation is made with a certain value of pulse energy (Joule) and frequency (Hertz) in Holmium laser lithotripsy and the multiplication of these values gives us total power (Watt). Devices with maximum power of 20 Watt and 30 Watt are used in clinical practice.

Comparison of Retrograde Intrarenal Surgery and Percutaneous Nephrolithotomy Methods For Management of Big- Sized Kidney Stones(? 4 cm): Single Center Retrospective Study.

Unlabelled: Purpose: Management of ? 4 cm sized kidney stone is a rarely seen problem in urology. Few studies are present about this issue. Percutaneous nephrolithotomy(PNL), Retrograde Intrarenal Surgery(RIRS) and open surgery are the methods used in stone management.
