We evaluated signs and symptoms of the transurethral resection syndrom
e recorded during and after 273 transurethral prostatic resections per
formed at 2 hospitals between 1984 and 1993. Glycine solution was used
as the irrigant and ethanol served as a tracer for fluid absorption.
The incidence and severity of symptoms that could possibly be related
to the syndrome increased progressively as more glycine solution was a
bsorbed. Patients who absorbed 0 to 300 ml. of glycine solution had an
average of 1.3 such symptoms. This number increased to 2.3 when 1,001
to 2,000 ml. were absorbed, 3.1 when 2,001 to 3,000 ml. were absorbed
and 5.8 for volumes greater than 3,000 ml. Nausea and vomiting occurr
ed significantly more often when 1,001 to 2,000 ml. were absorbed comp
ared to no absorption. Confusion and arterial hypotension were other p
rominent signs of fluid absorption, whereas hypertension was not. The
severity of symptoms was markedly aggravated when more than 3,000 ml.
were absorbed. Extravasation resulted in higher risks of bradycardia,
hypotension and failed spontaneous diuresis postoperatively than absor
ption by the intravascular route.
