Abstract

PURPOSE
To investigate the prophylactic effect of Tamsulosin, a super-selective alpha-1a adrenergic blocking agent, on the development of urinary retention in men undergoing elective inguinal herniorrhaphy.
MATERIALS AND METHODS
From May 2010 through November 2011, a total of 80 males who underwent elective inguinal herniorrhaphy in a university hospital were included in this study. Patients were randomly assigned to one of two groups. In group one (control), the patients were given two doses of placebo orally, 6 hours before surgery and 6 to 12 hours after surgery. Patients in group two were given 0.4 mg of Tamsulosin orally in the same manner as the placebo. All patients were closely followed for 24 hours post-operatively, and any voiding difficulties or urinary retention was recorded.
RESULTS
There were 40 patients in group one (control group) and 40 patients in group two (Tamsulosin group). The patients' mean age was 64 years. In group one, 6 patients and in group two, 1 patient required catheterization. Thus, 15% of patients in group I and 2.5% of patients in group II had urinary retention. The difference in the requirement for catheterization was statistically significant (p=0.04). The technique of herniorrhaphy, the side of the body in which the hernia was located, the type of anesthesia, the duration of the surgery, and the severity of pre-operative urinary symptoms had no significant effect on the incidence of urinary retention.
CONCLUSIONS
The use of perioperative Tamsulosin represents an effective strategy to reduce the risk of post-operative urinary retention following inguinal herniorrhaphy.
