[Spermatic cord seal-up injection for acute epididymitis: clinical observation of 56 cases]

To investigate the clinical effect of spermatic cord seal-up injection on acute epididymitis and its mechanisms.

A total of 120 cases of acute epididymitis were allocated to a trial group (n = 56), aged 18 - 78 (38.4 +/- 9.6) years, and a control group (n = 64), aged 14 -82 (41.3 +/- 7.2) years. The patients in the trial group were given seal-up injections of a mixture of lidocaine, gentamicin (or Amikacin) and dexamethasone into the spermatic cord, qd or bid, for 2 courses of 5 days each, with an interval of 3 to 5 days. Those in the control group were treated by intravenous drip of penicillin, qd, intramuscular injection of Streptomycin, bid, and oral medication of SMZCo (SMZ-TMP), bid, with the initial dose doubled. After less than 2 weeks of treatment, we compared the therapeutic effects between the two groups of patients.

In the trial group, 53.6% of the patients were basically cured, 37.5% obviously improved and 91.1% improved (total rate of effectiveness). The average treatment time for the improved cases was (9.2 +/- 0.5) d. In the control group, 40.6% of the patients were basically cured, 31.2% obviously improved and 71.8% improved (total rate of effectiveness). The average treatment time for the improved cases was (12.8 +/- 0.7) d. There were significant differences between the two groups in the total rate of effectiveness and the average treatment time for the improved cases (P < 0.05).

Spermatic cord seal-up injection for acute epididymitis deserves wide clinical application for its simple operation, good tolerance, short therapeutic course and high safety and efficacy.
