Calculous Disease
9 cases on medical expulsive therapy at the five-millimeter stone-size threshold, thiazide therapy for hypercalciuria after NOSTONE, potassium citrate intolerance and its alternatives, febuxostat after CARES in coronary disease, oral chemolysis for a large uric acid stone, empiric therapy versus metabolic testing after a first stone, acetohydroxamic acid for struvite stones, enteric hyperoxaluria after bariatric surgery, and calcium phosphate stones on topiramate — choose a case below to open its full multi-voice debate.
Two patients with distal ureteral stones, one on each side of the five-millimeter line the largest tamsulosin trials disagree about — and a genuinely different answer for each of them.
NOSTONE overturned decades of thiazide practice for stone prevention — including, unexpectedly, in the hypercalciuric patients the drug was supposed to help most.
The standard citrate therapy for his hypocitraturia keeps making him sick enough to stop taking it — and every alternative brings its own real cost.
His allopurinol option closed on genetic grounds years ago. Febuxostat is the only other xanthine oxidase inhibitor — in a patient whose coronary disease is exactly the population CARES raised its warning about.
A 20-millimeter uric acid stone is large enough to make surgery straightforward and dissolution genuinely uncertain — but she has real reasons to want to avoid an operation if she can.
The guideline-correct next step is a 24-hour urine collection he may never actually complete — and starting nothing while waiting for it is not a neutral choice.
A residual struvite fragment and a recurrent Proteus infection that antibiotics alone haven't resolved — and the one drug that reliably slows the stone's growth has a real cost of its own.
The surgery that fixed his diabetes and his knees eight years ago is also the reason his kidneys are now forming stones — and that anatomy isn't something any of today's options can undo.
The drug that finally controls her seizures is also, through the same mechanism, the reason her urine keeps forming calcium phosphate stones — and the usual fix for that biochemistry has a real paradox built into it.
