Poliüri
Özet
Poliüri, yetişkinlerde günlük 3 litreyi aşan idrar çıkışı olarak tanımlanan ve su homeostazını sağlayan vazopressin (ADH) hormonu veya susama mekanizmasındaki bozukluklardan kaynaklanan yaygın bir durumdur. Bu sendrom temel olarak yetersiz ADH salınımı (santral diyabet insipitus), böbreklerin bu hormona duyarsızlığı (nefrojenik diyabet insipitus) veya aşırı sıvı alımı (primer polidipsi) şeklinde üç ana grupta sınıflandırılır. Tanı sürecinde su kısıtlama testi "altın standart" kabul edilirken; tedavi stratejileri etiyolojiye göre düşük sodyumlu diyet, tiyazid diüretikler veya desmopressin replasmanını içermektedir.
Polyuria is a common clinical condition defined as urine output exceeding 3 liters per day in adults, typically resulting from disturbances in water homeostasis regulated by vasopressin (ADH) and the thirst mechanism. The syndrome is primarily categorized into three types: central diabetes insipidus due to deficient ADH secretion, nephrogenic diabetes insipidus caused by renal insensitivity to ADH, and primary polydipsia involving excessive fluid intake. While the water deprivation test remains the diagnostic "gold standard," management strategies vary by etiology and include low-sodium diets, thiazide diuretics, or desmopressin replacement therapy.
