RESUMEN
<p><b>OBJECTIVE</b>To investigate the clinical improvement of patient's sperm quality after the therapy on chronic prostatitis (CP) with double-balloon and triple-channel transurethral perfusion and drainage catheter.</p><p><b>METHODS</b>Double-balloon and triple-channel transurethral perfusion and drainage catheter along with millimeter wave physical therapy and intravenous infusion with antibiotics were adopted to treat 58 CP patients. The patient's sperm quality was analyzed pre- and post- therapy by Computer-assisted Sperm Analysis Instrument.</p><p><b>RESULTS</b>The comparison of patient's sperm quality parameters between pre- and post-therapy: percentage of motile sperm (42.66 +/- 17.12)% vs (55.23 +/- 14.79)%, grade a sperm (12.63 +/- 12.50)% vs (29.84 +/- 14.86)%, grade a + b sperm (29.14 +/-15.04)% vs (42.28 +/- 12.67)%, amplitude of the lateral head displacement (ALH) (3.04 +/- 1.55) microm vs (2.69 +/- 1.67) microm. The differences between pre- and post-therapy in above mentioned sperm parameters were all statistically significant (P < 0.01). While the differences among other sperm parameters were not statistically significant (P > 0.05).</p><p><b>CONCLUSION</b>Timely and effective therapy with transurethral perfusion and drainage catheter can improve the patient's sperm quality significantly, but sperm movement function cannot resume completely in a short time.</p>
