“…74 Some studies have assessed the efficacy and safety of increasing the number of shock waves per session to >4000. 84,85 Recommendation: Patients with upper ureteric stones should initially receive low-energy shocks, with gradual voltage escalation up to maximum energy (level 2, strong recommendation). If unsuccessful, repeat SWL can be considered but more than two treatments to the same ureteric stone has little incremental benefit and URS should then be considered (level 4, moderate recommendation).…”

“…There is no consensus on the optimal number of shock waves [2], although each manufacturer advises on shock wave number and energy. A study group has reported that an expanded number of shocks per one session improved SF rate [5,21]. On the other hand, a higher number of shocks per session may be ineffective.…”

To compare the treatment success rate and safety of reduced (30 shocks/min, 1,200 shocks/session) versus standard (60 shocks/min, 2,400 shocks/session) extracorporeal shockwave lithotripsy for the management of renal stones. Materials and Methods: We retrospectively analyzed 404 patients who underwent extracorporeal shockwave lithotripsy for 5-20mm renal stones between April 2011 and March 2019. Patients selected the reduced or standard protocol (group R and S) after explaining the potential benefits and disadvantages. The primary outcome was treatment success within 12 weeks, which was defined as no residual fragment or fragments <4 mm on ultrasonography and plain radiograph. Results: In total, 94 and 310 patients underwent shockwave lithotripsy with a reduced and standard protocol, respectively. The background characteristics of the participants did not significantly differ. The treatment success within 12 weeks was achieved in 78 (83.0%) patients in group R and 259 (83.5%) in group S (p=0.88). The median number of the session was 3 (interquartile range, 2-4) in both groups (p=0.53). The total complication rates were 5.4% in group R and 6.1% in group S. Three (1.0%) patients in group S experienced perirenal hematoma, which was conservatively treated. The reduced protocol was not associated with treatment success in the multivariate analysis adjusted for potential confounders (odds ratio, 0.91; 95% confidence interval, 0.46-1.80; p=0.78). Conclusions: The new treatment amendment with a slower delivery rate successfully reduced the total number of shocks need to fragment renal stones <20 mm without compromising the stone-free rate.
