Abstract

Objective: Descriptive study on 42 patients who had a hematospermia, were urologic examination and underwent a pelvic 1.5 Tesla MRI at Hanoi Medical University Hospital, from 8/2020 to 8/2022. Method: These hematospermia patients were divided into three groups depended on their seminal vesical signal intensity: groupe A had a high- intensity signal on T1W and low-intensity signal on T2W images (fresh hemorrhage), group B had  a high-intensity signal in T1W as well as T2W (old hemorrhage) and group C had a iso-intensity signal T1W (no hemorrhage) and from that, the sensibility of MRI in the detection of seminal vesicles bleeding was calculated. These groups of signal intensity were compared to the freshness (color) of seminal fluid of hematospermia patients. Results: Mean patient age 39,8±13 (min: 21; max: 84), most frequence age range from 30 to 60 (62%). 16 patients were lost their clinical data so we could not access the seminal fluid colors. Among the last 27 patients, 16 patients had a first hematospermia (59%) and 11 patients had multiple or persistent (≥2) hematospermia in their history. Regarding to the freshness of hematospermia, only 22 patients were reported the blood color in the seminal fluid, among them 9 patients had the red color (49%), 4 patients had the pink color (18%), 7 patients had the brown color (32%) and only 2 patients had the dark color (9%) of seminal fluid. Regarding to the signal intensity MR of seminal vesical, 22 patients had the signal intensity of group A (52%), 8 patients in group B (19%) and 12 patients in group C (29%). The sensibility of MRI to detect the bleeding of seminal vesicles was 71%. In comparison of the signal intensity of seminal vesicles to the blood situation of seminal fluid, all the color types of blood presented in the group A but most of them was the brown color. The group B was presented only the red and brown color of blood. Conclusion: Hematospermia was an usual anomaly in the sexual activity men. The signal intensity of seminal vesicle did not refer to the blood situation of the seminal fluid but MRI had the best value and non invasive imaging modality to detect the bleeding in the seminal vesicules.
