Dilutional hyponatraemia following transurethral operation for clot retention

Dilutional hyponatraemia with symptoms (TUR syndrome) may occur not only in association with transurethral prostatic resection, but also in other operations in which electrolyte-free irrigating fluid is used. This case report describes a patient who developed the TUR syndrome after blood clots had been removed from the bladder with the aid of a transurethral resectoscope.
