Flexible ureteroscopy with holmium laser lithotripsy: a new choice for intrarenal stone patients.
Urol Int. 2015; 94(1):93-8.UI

Abstract

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.
