An Innovative Technique of Transurethral Seminal Vesiculoscopy with Ultrasonic Lithotripter for Severe, Persistent Hematospermia.

Abstract

Transurethral seminal vesiculoscopy (TSV) provides an efficient approach to diagnose and treat hematospermia, but still needs further improvement in manipulation and corresponding instruments. In this study, we develop an innovative technique with ultrasonic lithotripter (EMS) to treat severe, persistent hematospermia. Data of patients who underwent TSV with or without ultrasonic lithotripter between May 2012 and December 2015 was reviewed. For the innovative procedure, a 3.3F ultrasonic lithotripter was introduced through the working channel of an 8F seminal vesiculoscope to remove calculi, blood clots, or purulent material, whereas in routine procedure, the holmium laser lithotripsy was performed with lower energy (maximum power 10 W). Complication, hematospermia recurrence, the operative time, and postoperative hospitalization were recorded. A total of 30 patients, 16 in Group A (routine TSV) and 14 in Group B (TSV with ultrasonic lithotripter procedure), were involved in this study. The median follow-up time for patients in Group A and B was 28 and 31 months, respectively. The mean operative time in Group A and B was 66 and 50 minutes, respectively (p < 0.05). All the TSV procedures in Group B were successful, except one patient had a two-stage procedure because of right seminal vesicle stones accompanying with pus. One patient in Group A had the discontinuation of the procedure because of accidental bleeding during stone fragmentation. During the follow-up, two patients in Group A had recurrent hematospermia and underwent the second TSV, whereas no recurrence happened in Group B. No epididymitis, retrograde ejaculation, rectal injury, incontinence, bladder neck contracture, or erectile dysfunction happened in both groups. TSV with ultrasonic lithotripter enables a more reliable, effective, and convenient procedure to diagnose and treat severe, persistent hematospermia. It controls the recurrent hematospermia with less operative time and complication.
