“…[10] In 1990s, successful results have been published for fURS in the treatment of urolithiasis from centers with high caseloads. Grasso and Ficazzola [11] reported a SFR of 94% and 95% for stones of ≤10 mm and 11-20 mm, respectively.…”

Retrograde intrarenal surgery (RIRS) has become an effective and safe treatment modality in the management of urinary system stone disease. Recent developments and innovations in the flexible ureterorenoscope and auxiliary equipment have made this procedure easier and more effective with increased success rates. RIRS can be used as a primary treatment in patients with renal stones smaller than 2 cm, prior unsuccessful shock wave lithotripsy, infundibular stenosis, renoureteral malformation, skeletal-muscular deformity, bleeding diathesis and obese patients. In the second part of this detailed review for RIRS, effect of stone composition on success rate, preoperative assessment of stone-free rate, the cost of this modality, education for RIRS, fluoroscopy use, the current role of RIRS in the treatment of various urolithiasis types and special conditions, and combined treatment methods are discussed with up-to-date literature.

“…stone-free) on renal sonography with a minimum three-month follow-up. 17 Extreme anatomical variants, including a long infundibulum, acute infundibulopelvic angle, and a dilated collecting system, correlated with surgical failures. Of the 19 surgical failures eight were secondary to inability to access the lower pole and 11 were secondary to inability to render the patient stonefree.…”

“…[9] The spatial anatomy of the lower renal pole plays a significant role in the stone-free rate after both SWL and fURS treatments. [17,18] Grasso and Ficazzola [18] evaluated 90 stone burdens that were located in lower pole and treated with fURS and showed that success rates decrease significantly when the stone size exceeds 20 mm. Of the 19 failures, 8 were secondary to the inability to access the lower pole.…”

“…Of the 19 failures, 8 were secondary to the inability to access the lower pole. [18] In another study, El-Nahas et al [19] compared fURS with SWL for the treatment of lower pole stones and showed that fURS had significantly higher success rates but no increase in the complication rates. In our study, the majority of the stones were located in the lower pole in both groups (52.5% vs. 49.5%).…”

Objective: Shock-wave lithotripsy (SWL) is the first-line treatment for the active removal of small and medium-sized kidney stones. Flexible ureterorenoscopy (fURS) is recommended after failed SWL treatment. The aim of this retrospective analysis is to evaluate whether prior unsuccessful SWL treatments affect the outcomes of fURS. Material and methods:Data from 206 patients who underwent fURS for the treatment of renal stones between September 2009 and January 2011 were collected, and the patients were divided into two groups according to their previous SWL treatment. The patient demographics, stone characteristics, operation and fluoroscopy times, stone-free rates and complications were compared.Results: Of the patients, 114 (55.3%) did not undergo SWL prior to fURS (Group 1), whereas 92 (44.6%) completed a minimum of 3 sessions of SWL and waited at least 2 weeks before the fURS operation (Group 2). Although the mean stone number was higher in Group 2, this difference was not significant (p= 0.06). The mean operation (p= 0.12) and fluoroscopy times (p= 0.69) were similar between the groups. The mean operation time per mm 2 stone and fluoroscopy time per mm2 stone were not significantly different (p= 0.64 and p= 0.76, respectively). The length of the hospitalization and the overall complication rates were similar. After the third postoperative month, the stone-free rates were not different between the groups (82.5% and 86.9%, respectively, p=0.38). Conclusion:The stone-free and complication rates of fURS were not affected by previous SWL therapy.
