“…Clinical evidence showed that the renal SFR was related to the stone composition and the exact localization of the stones [9,11]. In our study, the SFR was significantly lower for stones located in the lower calyx than for stones located elsewhere (p < 0.001 for primary SFR; p = 0.006 for 6-month SFR).…”

“…This is a major weak point of FURS, as multiple procedures and an extended time of stone extraction might be required to clear out renal stones completely. Miernik et al [9] reported successful outcomes from FURS for renal stones of 20-60 mm, with a primary SFR of 63.2% and an overall CT-controlled SFR of 81.8% after 3 months. In our study, patients with a stone burden of 20-40 mm acquired a satisfactory overall SFR of 85.8% after 6 months.…”

“…Although the EAU guidelines on urolithiasis do not recommend FURS as the routine first-line therapy for renal stones >15 mm, some researchers have published their data on the FURS approach and have recommended its use for high success and low complication rates [9,10,11]. …”

Objective: To evaluate the efficiency and safety of flexible ureteroscopy (FURS) and holmium lithotripsy for intrarenal stones and to stratify the efficiency and safety by stone burdens of ≤20, 20-40, and ≥40 mm. Methods: Five hundred eighty-two patients with intrarenal stones were treated with FURS and holmium lithotripsy at a single department from August 2008 to October 2013. Stone size was evaluated by calculating the cumulative stone diameter of all intrarenal stones, and stone-free status was defined as the absence of any stone or stone fragment <1 mm in the kidney. Results: Data analysis revealed a mean stone burden of 21.8 ± 7.6 mm. The overall primary stone-free rate (SFR) was 65.3%, which increased to 89.0% 6 months after the first surgery. Complications developed in 6.7% of patients. A significant difference was found between lower-calyx stones and other stones (p < 0.001; p = 0.006), while noncalcium stones had a much higher SFR than calcium stones (p < 0.001; p = 0.04). Conclusion: Our study showed that the overall renal SFR with the use of FURS and holmium lithotripsy was satisfactory, with a relatively low complication rate. We believe that FURS with holmium lithotripsy could be a valuable choice for patients with renal stones, especially for patients with a cumulative stone burden ≤40 mm.

“…The declared stone free rate of RIRS is about 97%, complication rates are lower than in other initiatives [40] . RIRS can be considered a proper alternative to PCNL in cases with significant comorbidity (anticoagulation, cardiopulmonary disease, advanced age) [41] , and in cases with additional adverse anatomical factors such as obesity and renal malformations [42] .…”

Urolithiasis is a common disease that affects urinary tract in all age groups. Both in adults and in children, stone size, location, renal anatomy, and other factors, can influence the success of treatment modalities. Recently, there has been a great advancement in technology for minimally invasive management of urinary stones.The epoch of open treatment modalities has passed and currently there are much less invasive treatment approaches, such as percutaneous nephrolithotomy, ureteroscopy, shockwave lithotripsy, and retrograde internal Surgery. Furthermore, advancement in imaging technics ensures substantial knowledge that permit physician to decide the most convenient treatment method for the patient. Thus, effective and rapid treatment of urinary tract stones is substantial for the preservation of the renal function. In this review, the effects of the treatment options for urinary stones on renal function have been reviewed. Core tip: In this article, urinary stone disease, treatment options and its effects on renal function are examined. Moreover, in the light of recent publications, effect of treatment options on functional state of the kidney in patients with renal impairment is investigated.Mehmet NM, Ender O.
