Randomized Controlled Trial Comparative Study
Comparative analysis of effectiveness of two local anesthetic techniques in men undergoing no-scalpel vasectomy.
To compare the effectiveness of two local anesthetic techniques in men undergoing no-scalpel vasectomy. ⋯ No-needle anesthesia with jet injection reduced the pain associated with traditional delivery of anesthesia to the skin and vas deferens before no-scalpel vasectomy. Additional studies are needed with more subjects to evaluate whether the decrease in procedural pain is statistically significant when comparing the two types of anesthetics.

Randomized Controlled Trial
Tadalafil (Cialis) and erectile dysfunction after radiotherapy for prostate cancer: an open-label extension of a blinded trial.
To determine the efficacy of tadalafil (Cialis) in patients with erectile dysfunction after three-dimensional conformal external beam radiotherapy for prostate cancer in an extended open-label phase of the blinded trial. ⋯ Tadalafil is effective in many patients with erectile dysfunction after three-dimensional conformal external beam radiotherapy for prostate cancer. In the open-label extension of the trial, tadalafil showed the same efficacy as in the blinded phase.
