Transurethral bipolar plasma kinetic resection of ejaculatory duct for treatment of ejaculatory duct obstruction

Abstract

To evaluate the efficacy of transurethral bipolar plasma kinetic resection of ejaculatory duct for ejaculatory duct obstruction. The clinical information of 42 cases of ejaculatory duct obstruction was analyzed between July 2008 and June 2012. The diagnostic criteria included semen analysis, fructose and neutral α-glucosidase measurement in seminal plasma, transrectal ultrasonography, magnetic resonance imaging and vasography necessarily. Endoscopic procedure with bipolar plasma kinetic resection of ejaculatory duct was performed in all patients. Among these cases followed up 6 ≈ 24 months after operation, 38 patients (90.5%) had improved semen parameters, 23 azoospermic patients (60.5%) had sperm in the semen and 13 patients' wife (31%) achieved pregnancies in 42 cases of bipolar plasma kinetic resection of ejaculatory duct. Postoperative complications ensued as epididymitis in 1 case, watery ejaculate in 1, but no serious complication was observed. Bipolar plasma kinetic resection of ejaculatory duct appears to represent a promising endoscopic treatment alternative for ejaculatory duct obstruction patients, with high efficacy, less complications, quicker recovery and satisfactory follow-up parameters.
