Loupe-Assisted Varicocelectomy With Nitroglycerin Instillation Versus Microscopic Varicocelectomy

Goal: To evaluate the safety and effectiveness of subinguinal microscopic varicocelectomy versus subinguinal loupe-assisted varicocelectomy with nitroglycerin instillation as a vasodilator. Materials and Procedures: 60 patients were enrolled in our prospective randomized trial between May 2023 and April 2024. They were split into two groups, Group A undergoing Loupe varicocelectomy (LV) with nitroglycerin instillation, and Group B undergoing Microscopic varicocelectomy (MV). Nitroglycerin was administered to the LV group following delivery and cord incision to help visualize cord veins and arterial pulse and avoid confusion with other cord structures that were to be preserved. Three months after the procedure, both groups had scrotal Doppler and semen analysis.
