Comparison of Percutaneous Nephrolithotomy (PCNL) and Retrograde Intrarenal Surgery (RIRS) for Management of Inferior Calyceal 1-2 cm Stones: A Matched Pair Analysis
Journal Title: Journal of Medical Science And clinical Research - Year 2018, Vol 6, Issue 6
Abstract
Objective: To compare percutaneous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS) for the treatment of lower calyceal calculi with diameter of 1- 2. Method: 59 patients who had renal stones ranging from 2 to 4 cm in diameter were treated with RIRS. The outcomes of these patients were compared with patients who underwent PCNL using matched-pair analysis (1:1 scenario). The matching parameters were the size, number and location of the stones as well as age, gender, body mass index, solitary kidney, degree of hydronephrosis, presence of previous shock wave lithotripsy and open surgery. Results: The two study groups were comparable for demographic characteristics and stone characteristics. It was found that RIRS is comparable to PCNL as a treatment modality in inferior calyceal renal stones of size 1 – 2 cm. The efficacy as defined by stone clearance rate was similar in the two procedures. RIRS had a shorter hospital stay, lesser morbidity and complications compared to PCNL. Conclusion: RIRS is an effective and safe alternative to PCNL in the treatment of inferior calyceal stones of size 1 – 2 cm. The choice of surgical technique between PCNL and RIRS should depend upon the expertise and choice of the surgeon as well as take the financial capability of the patient into account
