Open inguinal hernia repair is one of the most common surgical procedures. Despite the fact that different of anesthetic procedures are proposed as alternatives to spinal anesthesia, the combination of spinal anesthesia with open inguinal hernia repair is preferred from both surgeons and patients. One disadvantage of this combination is the high incidence of post-surgery urinary retention, especially in men above 50 years old. This complication is partially attribute to overstimulation of the a1 adrenergic receivers of the bladder and the prostate. Preoperative administration of elective a1 blockers could inhibit this effect without side effects, since this drugs don't have systemic effect.
