The right kidney stone (5.1×6.6mm in interpolar calyx) has a reasonable chance of passing with conservative management — adequate hydration (2.5–3L water daily), alpha-blocker (Tamsulosin 0.4mg), and pain relief. However, the left ureteral stone (4.3×9.7mm) is too large to pass on its own — stones >6mm in the ureter rarely pass spontaneously and will almost certainly require intervention. Ureteroscopy with laser lithotripsy or ESWL will be needed for the left stone. Please consult a urologist urgently as an obstructive ureteral stone can damage the kidney if untreated.
