“…Cumulative success rate of RIRS after multiple sessions has been reported as 77%-93% in renal stones greater than 2 cm. [9][10][11][12][13][14] Grasso et al used fiberoptic ureteroscope for noninfectious stones greater than 2 cm that were not suitable for PCNL and reported their success rate as 93%. Breda et al [9] reported a cumulative postprocedural success rate of 93% after 2.3 sessions on average in stones with a diameter of 2-2.5 cm.…”

“…Although a number of studies compared the results of PCNL and RIRS in intrarenal stones smaller than 2 cm, only a few studies have investigated their results in renal stones greater than 2 cm. [11][12][13][14][15] In 2011, Akman et al [15] studied patients with renal stones 2-4 cm in size and reported a success rate of 73.5% with a single session of RIRS and 91.2% with a single session of PCNL, and the stone-free rate was found to be 91.2% after 1.2 RIRS sessions on average. In our study, stone-free rates were 91.8% for a single session PCNL and 66.6% for a single session RIRS; however, the stone-free rate increased to 87.7% after the second session of RIRS.…”

Objective: To evaluate the safety and efficacy of retrograde intrarenal surgery (RIRS) in the treatment of kidney stones greater than 2 cm and to compare its results with those of percutaneous nephrolithotomy (PCNL). Material and methods:We retrospectively analyzed a total of 143 patients: 86 patients (53 males and 33 females) who underwent PCNL and 57 patients (37 males and 20 females) who underwent RIRS between October 2009 and October 2013. Results:The mean duration of operation was 100.26±33.26 min in the RIRS group and 75.55±21.5 min in the PCNL group (p<0.001). The hospital stay was significantly shorter in the RIRS group (1.56±0.8 vs. 4.57±2.1 days in the RIRS and PCNL groups, respectively; p<0.001). Stone-free rates after one session were 66.6% and 91.8% of the RIRS and PCNL groups, respectively. The stone-free rate of the RIRS group improved to 87.7% after the second session. Blood transfusions were required in two patients in the PCNL group. Complication rates were higher in the PCNL group. Conclusion:This study revealed that RIRS can be an alternative to PCNL in the treatment of kidney stones with a diameter of 2-4 cm especially in patients with comorbidities.

“…As electrohydraulic lithotripter was the only one available instrument for fURS at that time, fURS was not an acceptable treatment option for large stones because of its high complication rates. Grasso et al [15] published the results of fURS with holmium:YAG laser in 45 patients in whom PCNL was contraindicated due to their comorbidities. They reported SFR after first session as 76%, while it rose up to 91% after retreatment with fURS with an overall postoperative complication rate of 2%, where they defined success as residual stone fragments smaller than 2 mm.…”

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.

“…The utility of this approach for larger stones remains less well-defined, although in small series has been associated with stone-free rates after a single treatment session of up to 60%. 27 When PCNL is chosen as the most appropriate form of management, preoperative planning is essential. Due to the long distance between skin and stone in obese patients, it may be necessary to use a longer access needle, working sheath and/or rigid nephroscope.…”

Background: Efficacy and safety of percutaneous nephrolithotomy (PCNL) have been demonstrated in obese individuals. Yet, there is a paucity of data on the outcomes of PCNL in morbidly obese patients (body mass index [BMI] >40). Methods: Perioperative and stone-related outcomes following PCNL in morbidly obese patients was assessed using a prospective database administered by the Clinical Research Office of the Endourological Society (CROES). A multidimensional match of 97 morbidly obese patients with those of normal weight was created using propensity score matching. Student's t-test and Chi-square tests were used to assess for differences between the groups. Results: In total, 97 patients with a BMI >40 kg/m 2 were matched by stone characteristics with 97 patients of normal weight. The morbidly obese population demonstrated higher rates of diabetes mellitus (43% vs. 6%, p < 0.001) and cardiovascular disease (56% vs. 18%, (p < 0.001). Access was achieved more frequently by radiologists in the morbidly obese group (19% vs. 6%, p = 0.016). Mean operative duration was longer in the morbidly obese group (112 ± 56 min vs. 86 ± 43.5 min, p < 0.001). Stone-free rates were lower in the morbidly obese group (66% vs. 77%, p = 0.071). There was no significant difference in length of hospital stay or transfusion rate. Morbidly obese patients were significantly more likely to experience a postoperative complication (22% vs. 6%, p = 0.004). Interpretation: PCNL in morbidly obese patients is associated with longer operative duration, higher rates of re-intervention and an increased risk of perioperative complications. With this knowledge, urologists should seek to develop strategies to optimize the perioperative management of such patients.
