A Clinical Observation on the Spermatic Cord Torsion / 대한비뇨기과학회지

Torsion of the spermatic cord is an uncommon disease that is almost limited to prepubertal males. It causes strangulation to the blood supply to the testis, therefore requires urgent evaluation and diagnosis with immediate therapy to achieve preservation of a viable testicle. The patient suddenly develops severe pain in involved testicle, followed by swelling of the organ, reddening of the scrotal skin, lower abdominal pain, nausea and vomiting. The cryptorchid testis is prone to undergo torsion. A clinical study was made on 5 cases of spermatic cord torsion during the 18 months period from April, 1980 to December, 1981. The results were as follows: 1. The ages of the patients ranged from 45 drays of 16 years. Right side to left side ratio was 4:1. 2. The most common symptom of spermatic cord torsion was painful scrotal swelling. 3. Two cases were developed in undescended testicles and a case in the allergic purpura. 4. Twisted angle of the spermatic cord torsion was 1800 in 2 cases and 3600 in 3 cases. Type of torsion was extravaginal in 3 cases, and intravaginal in the other 2 cases. 5. Two cases were seen after 56 hours of onset. The involved testicles showed grossly complete necrosis and were orchiectomized. In the other 3 cases, immediate detorsion with fixation was given within 10-16 hours after onset. 6. histopathologic finding showed hemorrhagic infarction and necrosis of the testis, epididyrnis and spermatic cord in the orchiectomized cases, and generalized edematous change of epididymis and slightly separated seminiferous tubules by stromal edema in the cases of testicular preservation.

Effect of the Vasectomy on the Fine Structure of the Sperm-Acrosome in Rats / 대한비뇨기과학회지

Vasectomy has been increased as a popular method of birth control because it is simpler than other methods for men. But the vasectomy results in several problems such as relation to effect changes on the structure and function of the reproductive organ. The fate of non-ejaculated spermatozoa is postulated by some authors that those are disappeared by a progress of dissolution and reabsorption in the epididymis, and we have attempted to prove the true state of sperm-acrosome on the fine structure in vasectomized rats. The results were as follows: 1. Apical segments of the acrosome were swollen similar to the shape of club in many spermatozoa. 2. Discontinuities of the outer and inner acrosomal membranes were occasionally noted and there were complete losses of acrosomes in the certain places. 3. There was no evidence of significant changes in the nuclear structure, nor dilatation of the subacrosomal space. 4. Vasectomy might effect destructive changes in the acrosomes of the non-ejaculated spermatozoa in situ.

A Case of the Paratesticular Rhabdomyosarcoma / 대한비뇨기과학회지

Rhabdomyosarcoma is the most common tumor affecting the lower urinary tract of children, and is highly malignant with a tendency to involve local structure early and eventually metastasize to distant sites. Although about 15% of all juvenile rhabdomyosarcoma involve the urogenital tract most often the prostate, bladder, only a small number begin in the paratesticular tissues. Paratesticular rhabdomyosarcoma usually presents as a large intrascrotal mass that compresses the testis and epididymis, sometimes reaching the external inguinal ring. None case of paratesticular rhabdomyosarcoma has previously been reported in literature yet in Korea. We fist report a case of this tumor developed in a 6 years old boy and the relevant literature has been reviewed.

One Case of the Prader-Willi Syndrome / 대한비뇨기과학회지

Prader-Willi syndrome is characterized by such as infantile hypotonia, mental retardation hyperphagia with obesity and hypogonadism. We experienced one case of so called Prader-Willi syndrome associated with hypogonadotrophic hypogonadism, hypomentia, hyperphagia with obesity and cryptochism. Testicular biopsy revealed predominant Sertoli cells, decreased spermatogonia and edematous stromal tissue.
