[Double J-tube indwelling after transurethral seminal vesiculoscopy reduces recurrence of ejaculatory duct obstruction].

Objective: To introduce a surgical method involving the indwelling of double-J tubes (DJT) in the seminal vesicles after transurethral seminal vesiculoscopy (TSV) in order to reduce the recurrence of refractory ejaculatory duct obstruction (EDO).

Methods: This randomized controlled trial included 67 EDO patients undergoing TSV in our hospitals, 27 with (the trial group) and 29 without postoperative indwelling of DJTs in the seminal vesicles (the control group). We collected the general information on the patients and TSV-related parameters, including age, body mass index (BMI), preoperative use of antibiotics, history of urinary tract disease, operation time, hospital stay and intra- and postoperative complications, and performed comparative analyses particularly on the surgical effect, complications, recurrence rate and time to recurrence in the two groups of patients.

Results: The patients in the trial and control groups were followed up for (40.5 ± 10.6) and (32.5 ± 14.8) months, respectively. There were no statistically significant differences in the baseline data, intra- and postoperative complications, and postoperative hospital days between the two groups (P > 0.05). Compared with the controls, the patients in the trial group showed a significantly shorter operation time (［62.8±6.1］ vs ［49.5±7.7］ min, P < 0.05) and a lower recurrence rate than the controls (18.5% vs 44.8%, P < 0.05), but with no statistically significant difference in the median time to recurrence (21.0 mo vs 22.0 mo, P > 0.05).

Conclusion: The novel technique of indwelling double-J tubes in the seminal vesicles after TSV can significantly reduce the recurrence rate of refractory EDO.
