Clinical Trial Summary

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	incidence of urinary retention	inability to voluntarily void urine up to 8 hours post surgery	8 hours post surgery
Secondary	Prostate related Symptoms	identification of Prostate related Symptoms as preoperative risk factor of post surgery urinary retention. For the assessment of the prostate related symptomatology will be used the International Prostate Symptom Score questionnaire	Baseline
Secondary	Scrotal hernia Repair	evaluation of Scrotal hernia repair as preoperative risk factor of post surgery urinary retention.	Baseline, Inta-operative
Secondary	Duration of Surgery	Evaluation of the surgery duration as inta-operative risk factor of post surgery urinary retention.	Duration of Surgical procedure
Secondary	Use of opioids	Evaluation of the peri-operative administration of iv opioids as a peri-operative risk factor of post surgery urinary retention.	24 hours
Secondary	Iv fluid administration	Evaluation of the peri-operative iv fluid administration as a peri-operative risk factor of post surgery urinary retention.	24 hours
Secondary	Post-operative Pain	Evaluation of the post operative pain as a risk factor of post surgery urinary retention. For the assessment of the pain will be used the Visual Analog Scale (VAS) score at 6, 12 and 24 hours after surgery. (VAS Score Scale from 0-10, 0 no pain, 10 max pain)	24 hours
