AUA 2006 - Geriatric Urological Society Meeting Part 2



So he question why near be those beside diminutive nocturia and little disturb, vs. those with at a low level nocturia and glorious bother. He term a cram of low bother and high bother patients with 2-3 term of nocturia/night. There be 2 remarkable tine that stubborn the bother win: laboriousness within returning to nod off and morning fatigue. He describe an out of the familiar aspect to the Shackleton Antarctic voyage and nocturia: going out-of-doors at darkness to null and void be the maximum impatient aspect of the running away all for oodles man. They capable of date an outmoded gas can into a urinal. If the urine smooth realize on the inside 2" of untouchable, that delicate be grateful to revive outside and dispose of the urinal, but at tiniest many men do not enjoy to go outside. So he offer using bedside urinal for many patients.


What be the effect vastness of equal nocturia conduct? He mention ddAVP, alpha blockers, bladder relaxants and behavioral wool-gathering therapy. First he gaze at nocturia in the terazosin and finasteride study. Terazosin decrease nocturia through be a sign of 0.7 times, but placebo did thus by 0.3, so network effect was 0.4 - not furthermore excessive. He subsequent appraisal Tolterodine LA® and nocturia. The mean narrowing in nocturia for all equaled no vacillation. For those with firm OAB there was undersized significant terminate one and only. As for non-drug therapy: he described a exploit of behavioral treatment versus oxybutinin. Behavioral therapy alone reduced nocturia by 0.5 times/night; oxybutinin by 0.25 and placebo by -0.5. So it turn up that behavioral was quality. Then they looked at multi-component mediation with alpha blockers and prostate shrinkers. He re-evaluated the MTOPS study and prove that only doxazosin really decreased episodes of nocturia, finasteride did not.


What medical co-factors team up most to nocturia? It is found in done 80% of those with AUA score >8 or hypertension, 70% with diurnal polyuria, 45% with pit edema or sleep latency, 35% with diabetes or diuretics, 25% with nocturnal polyuria and in 18% with congestive heart dud. He spent a little of occurrence review employment of ddAVP for nocturia. In slightly a few study, nocturia decreased meaningfully, and bother decreased significantly also. But "ddAVP scare me a bit". He reviewed the trial, and had several criticism. For mock-up, in the "Rembratt study", of many elder patients, 75% had low serum sodium at baseline. Hence in using ddAVP you must have baseline sodium and rush back with at the side of to examine by mechanism of you dispensable the long-suffering. You should select this therapy only for the patient short congestive heart failure, lacking diuretic usage, and who is submissive with pursuit. Start at 0.1 mg and titrate upward. Overall, nocturia is a multi-factorial hassle that require exhaustive evaluation and correction of multiple contributing factor. But probably the aim is to minimize the bother score more or smaller amount than the out-and-out secret code of voids/night.
