Is Retrograde Intrarenal Surgery Prefereable Over Mini Percutaneous Nephrolithotomy in Patients With Renal Calculus of Less Than or Equal to 2 Cm Size?

Abstract

Objective: To compare intraoperative and post-operative outcomes between mini-percutaneous Nephrolithotomy (miniPCNL) and Retrograde intrarenoscopy (RIRS) groups. Materials and methods: A total of 66 patients were alternatively allocated to undergo miniPCNL (33patients, group A) and RIRS (33patients, group B) groups. All patients were evaluated by history, laboratory investigations, X-ray Kidney ureter bladder (KUB), Ultrasonography and computerized tomography (CT) scan to determine stone number, location and size. Operative time, stone free rate, duration of hospital stay and complications were compared between both groups. Results: Demographic parameters were comparable between two groups. Stone free rate was similar in both groups. Mean duration of procedure was less for miniPCNL when compared to RIRS with P < 0.0001. Duration of post-operative stay for miniPCNL was longer when compared to RIRS with P < 0.0001. Complications like intra operative bleeding, post-operative fever and blood transfusion were similar in both groups. The RIRS group patients experienced reasonably less pain postoperatively as per Visual analogue scale (VAS) score when compared to miniPCNL group with P < 0.0001. Conclusion: Though RIRS and miniPCNL have good and comparable stone free rate with low complication rates, favourable pain score and less hospital stay makes RIRS a preferred option over miniPCNL.
