Aim: The
aim of this study was to report our retrograde intrarenal surgery
experience for treatment of 2-4 cm sized kidney stones.
Materials and Methods: After local ethical committe approval, patient data
between 2014-2019 was reviewed. Patients who had been undergone RIRS for 2-4cm
sized kidney stones were included. Patients < 18 y old were excluded.
Results: There were 40 patients in our study. The average age
was 49.02±17.56. Twenty six patients were male, fourteen patients were
female.Ten patients had preoperative SWL history. Eleven patients had
preoperative JJ stent. Seventeen patients had no operation history. The average stone size was 22.48±3.67 mm. The
average stone volume was 2049±1291.89 mm3 . Thirty one patients had
opaque stones. The average Hounsfield unit was 1038±359.34 HU. In terms of
stone locations, one patient had mid pole stone, eight patients had lower pole
stone, one patient had pelvis stone , two patients had ureteropelvic
junction(UPJ) stone and six patients had multicaliceal stones. The mean
operation time was 76.15±35.79 min. All the patients had postoperative JJ
stent. In 37 patients UAS was used. Nineteen patients were stone free.
Complicatons were seen in three patients
Conclusion: Retrograde intrarenal surgery can be used for the
treatment of 2-4 cm sized kidney stones. Safety is an advantage for retrograde
intrarenal surgery. Need for multiple sessions and cost are disadvantages of
retrograde intrarenal surgery. Studies with prospective design and with longer
patient follow up are needed.
