Transurethral resection of the prostate (TUR-P) is still the gold stan
dard in the treatment of benign prostatic hyperplasia (BPH). Because t
he TUR-P morbidity has remained unchanged at 18% for years, it seemed
reasonable to look for therapeutic alternatives. The most critical poi
nt is the possibility of blood loos with a need for substitution even
if TUR-P is done by a highly experienced urologist. By infiltrating th
e prostate with a vasoconstrictive agent we looked for a technique to
reduce blood loss and resection time. In 19/35 patients, preoperative
infiltration of the prostate with 5 IE Ornipressin dissolved in 20 ml
NaCl was performed transurethrally. 16 patients served as controls (no
rmal TUR-P). In the Ornipressin group, blood loss was significantly lo
wer than in the control group. Compared with the conventional method,
resection time could be significantly reduced. Resection could be done
under excellent optical conditions. There were no severe side effects
. Short-term increase in blood pressure and reflex bradycardia could b
e treated.
