Retrograde Intrarenal surgery

Abstract

Background: RIRS has become an important treatment option for kidney stones in pediatric patients with the development of new-generation ureteroscopy and holmium laser. The present study was conducted to assess cases of retrograde intrarenal surgery. Subjects and Methods: The present study was conducted in a tertiary care centre over a period of one year on 120 cases of retrograde intra renal surgery (RIRS) performed in both genders. Renal stone location and stone clearance, laterality, stone size, operative time, hematuria, postoperative pain & fever, urosepsis, hospital stay, residual stones and need of an adjunctive procedure to achieve residual stone clearance. Results: Out of 120 patients, males were 70 and females were 50. Stones were detected in upper calyx in 50 cases, middle calyx in 40, lower calyx in 20 and pelvis in 10 cases. The mean size of stones was 8.1 mm, operative time was 62.1 minutes, hospital stay was 3.6 days, clinically insignificant radiological fragments were seen in 35 cases and residual stones were seen in 20 cases. Maximum cases of CIRF were seen in middle calyx (15) and residual stones were seen in lower calyx (7). The difference was significant (P< 0.05). Common complications were fever in 7, hematuria in 3, flank pain in 4 and urosepsis in 2 cases. Conclusion: Authors found that retrograde intrarenal surgery is a technically safe and effective procedure for the treatment of renal stones.
