Objective:To compare the outcomes in patients who have been treated with flexible ureterorenoscopy (f-URS) and minimally invasive percutaneous nephrolithotomy(mPCNL) in managing stone-bearing caliceal diverticula.Methods: Between September 2010 and September 2014, we performed a retrospective analysis of 55 evaluable patients with symptomatic stone-bearing caliceal diverticula, who underwent MPCNL(n=29) or F-URS (n=26) in our hospital.The success rate,operation time, stone-free status,symptom-free status,blood loss, mean postoperative hospital stays and postoperative complications were compared. All the data were analysed by chi-square test. Two-sided values of P< 0.05 were considered statistically.Results: There was no statistical difference between the groups for success rate,stone-free status and symptom-free status. Hospitalization time per patient was (4.53±0.85) d in the f-URS group, while it was (7.13±0.74) d in the mPCNL group (P<0.01).Two patients in mPCNL had large blood loss.Conclusions: Even though this study clearly shows that both techniques have high overall success and symptom-free rates with similar complication rates for stone bearing calyceal diverticulum, major complication rates may suggest consideration of the invasiveness of mPCNL. The f-URS procedure is advantageous with respect to a shorter hospital stay and absence of major complications. Therefore, it should be emphasized that the location/size of the stone and diverticula is an important factor for the selection of the procedure. |
