A prospective, randomized trial comparing conventional transurethral prostate resection with PlasmaKinetic vaporization of the prostate: physiological changes, early complications and long-term followup.

Purpose: We compared standard transurethral prostate resection with bipolar PlasmaKinetic prostate vaporization for bladder outflow obstruction using a Gyrus PlasmaKinetic Plasma V bar.

Materials And Methods: A total of 160 men were enrolled in a prospective, randomized trial. Those at higher risk for cancer were excluded by prostate specific antigen and digital rectal examination with or without transrectal ultrasound biopsy.

Use of glyceryl trinitrate patches in patients with ureteral stones: a randomized, double-blind, placebo-controlled study.

Objectives: To report a randomized, double-blind, placebo-controlled trial of glyceryl trinitrate (GTN) patches. The primary outcome measure was stone passage at 6 weeks. GTN is a potent smooth muscle relaxant that may offer benefit by both reducing pain and facilitating ureteral stone passage.
