TURP syndrome.
TURP (t ransurethral resection of the prostate) syndrome - it is a combination of fluid overload and hyponatremia, which occurs when large volumes of irrigation fluid are absorbed via open venous sinuses. The most commonly used irrigant is glycine 1.5% in water, which is hypotonic (osmolality 220 mosm/L). On average, patients absorb a total of 1–1.5 L, but absorption of up to 4–5 L can be possible.
