[Seminal vesiculoscopy-assisted thulium laser ablation for the treatment of ejaculatory duct obstruction: An analysis of clinical outcomes].

OBJECTIVE

To evaluate the clinical outcomes of seminal vesiculoscopy-assisted thulium laser ablation (SVS-TLA) in the treatment of oligoasthenozoospermia or azoospermia induced by ejaculatory duct obstruction (EDO).

METHODS

We retrospectively analyzed the clinical data on 42 cases of EDO-induced oligoasthenozoospermia or azoospermia in our Clinic of Andrology from April 2018 to January 2020, all definitely diagnosed and treated by SVS-TLA. We followed up the patients regularly after operation, obtained their routine semen parameters at 3, 6 and 9 months postoperatively, examined them by t-test and compared them with the baseline.

RESULTS

Operations were successfully completed in all the 42 cases, with an average surgery time of 52.7 minutes. Compared with the routine semen parameters collected 2 weeks before surgery, the semen volume, sperm concentration and total sperm motility of the patients were all significantly improved at 3, 6 and 9 months postoperatively (P < 0.01). Sperm were found in 40 cases at 3 months and in the other 2 cases at 6 and 9 months after surgery. Postoperative complications were observed in 7 cases, including epididymitis, perineal or testicular pain, and hematuria, which all disappeared after corresponding symptomatic treatment. No such serious complications as retrograde ejaculation, rectal injury, urethral stricture or urinary incontinence occurred in any of the cases after operation.

CONCLUSION

SVS-TLA is a safe and effective option for the treatment of EDO, which can significantly improve the semen quality of the patient without causing serious postoperative complications.
