1. Routine semen examination: There is no sperm or sperm in semen.
(1) For the obstruction above the bilateral sperm tube (excluding the prostate part), the semen is manifested as a small amount of liquid, no sperm, low fruit sugar content, acidic, and high citric acid content.
(2) The prostate or above (including the prostate) vasure pipe obstruction is displayed as a reduction in semen, no sperm, the pH value is neutral or alkaline, and the content of fructose and citric acid is low.
(3) If there are a small amount of sperm in the semen, it is prompted that there may be part or incomplete obstruction in the vastered pipeline.
2. A small scrotum incision of the vi -infusion pipeline angiography bureau, fix and display the vasal pipe, use the 2L pin, first injected about 0.5ml of about 60%compound pantrahide into the attachment direction, which can display the remote vasters and epididymia.Symptoms are punctured, injected with 2-3ml compound panhamine, which can display the closett of the puncture point, seminal vesicles, and ejaculation pipes.Recently, many scholars have reported that they can directly spate with the skin and expose the tube, and there is no need to run the scrotum incision.Normal vasters should be displayed as the shape and position of the vasters, seminal vesicles, and ejaculation pipes, and they are fully filled with contrast agents.
3. Surgical detection of internal surgery detection is another important means to diagnose the obstruction of the vasal pipeline, because some lesions cannot be discovered by physical examination or spermatic pipelines.
The order of detection is testicular, epididymia, and vasure tubes.While exploring, it is feasible for testicular biopsy. It is best to conduct simultaneous detection and surgical treatment to avoid secondary surgery.
