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.
