Tumors of the epididymis are rare. The most common one is adenomatoid tumor. At least more than two hundred cases have been reported in the literature but only one was reported by us last year in this country. We add another one which is involving bilateral epididymis simultaneously and review literature briefly.

PURPOSE: To evaluate the US findings of epididymal adenomatoid tumor. MATERIALS AND METHODS: Were trospectively reviewed US findings of four patients with histopathologically proven epididymal adenomatoidtumors. Lesions were evaluated for their size, location, margin, shape and echogenicity. RESULTS: The size of thetumors ranged between 0.5cm and 2cm and all occurred on the left side of the epididymis. Of the four cases, three were located at the tail of the epididymis and one at its head. The tumors were well marginated and spherical andecho-texture was variable but homogenous. CONCLUSION: The possibility of and adenomatoid tumor should be considered when the epididymal mass is round and has a clear margin and the echo-texture of ultrasound ishomogenous.

Monorchism is a congenital anomaly showing complete absence of a testis on one side. We experienced a cases of monorchism in an 11 year-old boy, diagnosed through exploratory laparotomy. We can find the spermatic vessels and was deferens, but not testis and epididymis on the right side. The opposite testis was normal on palpation. Herein, we add another one case of monorchism after the report of 2 cases in 1978.

In this cross-sectional retrospective study, 300 cycles of sperm retrieval from the epididymis and the testis on 213 patients for the intracytoplasmic sperm injection at the Infertility Department of Tu Du Hospital from March 2003 to May 2004 were examined. The results showed that: 100% cycles with embryos and the pregnancy rate of 47.9%; there is no complication except a mild scrotal discomfort lasting a few days after open surgery; percutaneous epididymal sperm aspiration (PESA) was the most performed retrieval technique (61%), which was easy-done, quickly-performed, safe and effective

PURPOSE: Epididymal anomalies in boys with an undescended testis have been well documented and most undescended testes are associated with patent processus vaginalis. However, the incidence of epididymal anomalies in descended testes has not well known. We performed a prospective study to determine the relationship between epididymal anomalies and patency of processus vaginalis in boys with hydrocele or cryptorchidism. MATERIALS AND METHODS: From January 1997 to February 1988, epididymal morphologies and the degrees of patency of processus vaginalis(closed, partially closed and open) were examined in 35 boys with hydrocele(37 testes) and 28 boys with cryptorchidism(29 testes) at the surgeries. RESULTS: No epididymal anomaly was found in all 3 hydroceles with closed processus vaginalis. Epididymal anomalies were found in 13 of 22 hydroceles with partially closed processus vaginalis and in 9 of 12 hydroceles with open processus vaginalis. All boys with undescended testes had open processus vagnialis and the epididymal anomalies were found in 27 of 29 undescended testes. The incidence of epididymal anomalies was highest in cryptorchid testes with open processus vaginalis and lowest in descended testes with closed processus vaginalis. Furthermore, epididymal anomalies were found to be more severe in association with more cranially located testes. CONCLUSIONS: The higher incidence of epididymal anomalies were associated with ipsilateral patency of processus vaginalis and testicular position. This finding suggests that the role of the epididymis in testicular descent may not be essential.

Diagnostic ultrasound was a simple, rapid, harmless, and painless method to visualize ultrascrotal contents, it provided information that was difficult to obtain on clinical examination. We recently tested the effectiveness of diagnostic ultrasound in 41 men with scrotal masses. In general, ultrasound was highly effective in differentiating and characterizing testicular and extratesticular masses. The following results were obtained. 1. The ultrasonic examination revealed 37 extratesticular lesions, 3 testicular lesions and 1 indeterminate lesion. Of the extratesticular lesions 22 were believed to be cystic but represented 18 hydroceles and 4 spermatoceles. 15 lesions were thought to be solid that represented epididymitis. 2. The accuracy rate the scrotal ultrasound, given a complete clinical history, was 97% in this series. 3. The tumor showed decreased echogenicity within the testicle, which was enlarged. The characteristic appearance of hydrocele, spermatocele were sonolucent cystic mass. The epididymis was enlarged in 11 patients with epididymitis, the echogenicity within testicle was decreased in 5 patients with epididymitis.

Xanthogranulomatous epididymitis is extremely uncommon inflammatory disease of the epididymis that may result in massive destruction of the organ. It's clinical manifestation mimics epididymal tumor or abscess, which does not allow easy discrimination between theses diseases. We report here on a case of xanthogranulomatous epididymitis in a 69 years old man that, did not respond to antibiotic therapy.

The ultrasonographic features in 26 cases of blunt testicular trauma were reviewed. Ultrasonography diagnosed correctly in 11 surgically proven cases of testicular rupture. There were three false-positive cases, two with a large scrotal hematocele and one with epididymis rupture. there were no false-negative cases. The sensitivity and specificity of ultrasonographic diagnosis were 100% and 80% respectively. The positive and negative predictive values were 78. 6% and 100% respectively. Therefore, the negative diagnosis by ultrasonography can warrant conservative therapy.
