Objective:
To report a case of transurethral endoscopic treatment of ejaculatory duct stones with transrectal ultrasound (TRUS)-guided perineal needle implant and ureteroscopic extraction of deferent duct stones in an infertile man.
Design:
Case report.
Setting:
Department of Urology, University of Catania, Italy.
Patient(S):
A 33-year-old man with azoospermia, low ejaculate volume, perineal discomfort, and unilateral seminal tract dilatation caused by obstructing lithiasis of the ejaculatory and deferent ducts.
Intervention(S):
Transurethral endoscopic treatment of ejaculatory duct stones with TRUS-guided perineal needle implant and ureteroscopic extraction of deferent duct stones.
Main Outcome Measure(S):
Improvements in symptoms and seminal parameters.
Result(S):
The patients had successful relief of symptoms and correction of obstructive azoospermia.
Conclusion(S):
This new technique allows a more rapid and targeted identification of ejaculatory duct lithiasis, and the ureteroscope enables management of distal seminal stones through the normal anatomic tract.
