May be...: Dod you mean eswl or lithotripsy through urethra ot bladder up to ureter/kidney? The post-rx sand/fragment passage may behave somewhat different. The size of sand/fragment after eswl highly varies depending on stone hardness; the ones after transurethral tends to be coarser. But, not seeing sands / fragments 4 days after either may be not unusual; so, don't worry, but take a kub as post-rx f/u...

Maybe passed: Check urine for micro rbcs ultrasound looking for hydro ;/or residual calcification. If both are negative, probably passed fine fragments.
