[Adrenoblockers in prophylaxis of acute urination retention after surgery]

The results of operations on the organs of the abdominal cavity and the small pelvis in 70 men are analyzed. For evaluation of the condition of the urogenital system and urination parameters preoperatively all patients underwent ultrasound examination of the urine bladder and the prostate with the residual urine evaluation, uroflowmetry. Summary value of the symptoms was evaluated according to international system IPSS and the quality of life was assessed (QOL). 30 patients administered doxazosin according to the scheme: 2 preoperative days 2 mg/day, then 3 days--4 mg/day, and 3 postoperative days--4 mg/day. 5 patients dook tamsulosin 0.4 mg/day for 5 preoperative days and 3 postoperative days. 35 men took placebo, in this group acute anuria in postop period was detected in 4 patients (11.4%). All of them were over 60 years and had benign hyperplasy of the prostate, they initially had disturbances in urination (in average Qmax = 9.7 ml/sec, IPSS = 7, QOL = 3). Ischuria was absent in patients administered alpha 1-adrenoblockers. The authors suggest that probability of the development of acute retention of urine in postoperative period is higher in persons, suffering from benign hyperplasy of the prostate and in those, who have initial disturbances in urination. The use of alpha 1-adrenoblockers preoperatively and in early postoperative period allows minimizing probability of development of ischuria paradoxa in men.
