Résumé

<p><b>OBJECTIVE</b>To investigate the correlation of age and sex hormones to the total volume (TV) and transition zone volume</p><p><b>METHODS</b>Eighty-two men were divided into two groups with the age of 60 as the dividing line. Prostatic TV (TZV and TZV were measured with transrectal ultrasound (TRUS) and the concentrations of total testosterone (T), free testosterone (fT) and estradiol (E2) were measured with radioimmunoassay. Exponential curve regression and one-factor analysis of variance (ANOVA) were used for statistical analysis.</p><p><b>RESULTS</b>Age was significantly correlated with TV, TZV and the TZV/TV ratio, P < 0.01. There was a significant positive correlation between the concentrations of fT and TZV, a negative correlation between those of E2 and TZV (P < 0.01), but no correlation between those of T and TZV (P > 0.05).</p><p><b>CONCLUSION</b>The significant acceleration of the TZV of the prostate after the age of 60 is related to sex hormones.</p>

Résumé

<p><b>OBJECTIVE</b>To make a comparative study of duplex ultrasonography (DU) and internal pudendal arteriogram (IPA) in the diagnosis of trauma-associated arteriogenic erectile dysfunction (ED).</p><p><b>METHODS</b>Seven patients suffering from arteriogenic erectile dysfunction caused by pelvic fracture trauma underwent comprehensive history inquiries and physical examinations by duplex ultrasonography and internal pudendal arteriogram, which ruled out neurogenic erectile dysfunction.</p><p><b>RESULTS</b>DU suggested penile artery blood flow injury, and IPA indicated artery injury in all the cases, including left internal pudendal artery injury, right or left common penile artery injury and bilateral common penile artery injury.</p><p><b>CONCLUSION</b>Trauma-associated arteriogenic erectile dysfunction may result from common penile artery injury and internal pudendal artery injury. DU is proved valuable for evaluating hemodynamic abnormalities of cavernous artery flow, and IPA useful in locating common penile artery and internal pudendal artery injury. DU can be used as the first line diagnostic means to define trauma-associated arteriogenic ED.</p>
