[Sonographic examination of scrotum and testes with a new scanning technique (author's transl)].

The subject of this report is an improved technique for sonographic examination of the scrotum and the testes. The method is simple; by using a waterbath, a mechanical compression of the testes is avoided. In all sections the scrotum may be continually observed and a good picture reproduction is possible. The report concerns the results of a prospective examination of 37 patients. The diagnoses of their condition could be confirmed by surgery or by follow-up examinations.

Scrotal palpation.

Proper examination of the scrotum consists of inspection, palpation and, if indicated, transillumination. Inspection may reveal the hypoplastic appearance of an undescended testicle; enlargement caused by a testicular mass; the "bag of worms" signifying a varicocele; findings typical of torsion of the spermatic cord, or the "blue dot" sign, which indicates torsion of the appendix testis or appendix epididymis. During palpation, the testis must be differentiated from the epididymis.

Pseudomalignant cytologic presentation of spermatic hydrocele fluid.

An unusual cytologic presentation of spermatic hydrocele fluid is reported. The aspirate contained highly atypical cells, exhibiting marked anisocytosis and nuclear abnormalities strongly suggestive of cancer. On histologic examination the lesion displayed pseudosarcomatous fasciitis in the cyst wall and foci of atypical reactive mesothelial hyperplasia in the lining. This case illustrates a potential pitfall in the cytology of spermatic hydrocele fluid.

Ultrasonography of the testis--correlation with radiotracer perfusion.

Ultrasonic study of testicular disease and paratesticular masses was carried out in 20 cases. In eight of these, comparison was made with pertechnetate perfusion studies performed concurrently. Testicular torsion was well revealed by both techniques. Acute orchitis, in the early stages, was shown more clearly by radiotracer, unless there was associated epididymal swelling or hydrocele. Chronic complications of inflammation, particularly abscess formation, were seen best by ultrasonography. Paratesticular masses could be studied only by ultrasound. These included both solid and cystic masses due to chronic epididymitis.

[Surgical possibility for refertilization of the male (author's transl)].

With the rising number of vasectomies the demand for refertilization procedures is increasing. Following vasovasostomy patency is achieved in 80 to 90% and fertility in up to 30%. About half of these figures are attained by epididymo-vasostomy. Encouraging experimental studies with an alloplastic sperm-reservoir justify its clinical application. Reasons for failure and for the discrepancy between patency and fertility following refertilization are: surgical technique, autoimmunization, adynamia and hyperactive phagocytosis within the epididymis.

Immersion ultrasonography of scrotal and testicular pathology.

A water-coupled free-immersion ultrasound scanner, the Octoson, was used to study 70 patients with scrotal disease. The main advantage of the immersion technique is the perfect overview of the whole male genital organ. Scrotal masses could be differentiated to a high percentage into intrascrotal fluid collections and intra- or extra-testicular solid lesions. In some cases, testicular tumors could be distinguished from inflammatory conditions on the basis of the ultrasound examination alone. According to out present experience, immersion ultrasound of the scrotum proved to be an effective method in disclosing the site, delineating the extent and characterizing the nature of extra- and intra-testicular disease.

Epithelial monolayers from human epididymal and efferent duct tubules; testosterone metabolism and effects of culture conditions on cell height and confluence.

Corpus epididymal and efferent duct epithelial cells on permeable supports formed confluent monolayers that resisted hydrodynamic equilibrium and created electrical resistance. Monolayers were formed sooner and were of better quality when fetal bovine serum (FBS), rather than bovine serum albumin (BSA), was present in glucose-free, rather than glucose-containing, media. Testosterone was converted to androstenedione by both cell types and conversion of both steroids to 5 alpha-reduced metabolites was higher in cells from the corpus epididymidis than from efferent ducts. Addition of heat-treated human spermatocoele fluid (similar to rete testis fluid) to the apical aspects of the cells increased cell heights when they were initially low, but some cytoplasmic damage was observed. New serum-free media (especially those designed for keratinocytes and mammary epithelial cells) could maintain cultured cells at heights found in situ.

Adult paratesticular tumors: report of two cases.

Paratesticular tumors are uncommon tumors, most being found incidentally at autopsy. The most common benign paratesticular tumor is the adenomatoid tumor. A somewhat less frequent benign paratesticular tumor, papillary cystadenoma, accounts for approximately 33 percent of all the primary epididymal tumors and is frequently seen in patients with Von Hippel-Lindau disease. Malignant tumors are rare. Of these, rhabdomyosarcoma is the most frequent. Seen almost exclusively in the pediatric population, paratesticular rhabdomyosarcomas account for 7 percent of childhood rhabdomyosarcomas. We describe two cases of paratesticular tumors in adults: a papillary cystadenoma of the epididymis in a 72-year old male, and an incidental rhabdomyosarcoma in a 49-year old male.

[Prevention of postoperative scrotal edema].

The authors describe the technique of scrotal elevation and compression for the prevention of postoperative scrotal hematoma. This technique was used in 30 patients undergoing hydrocelectomy, spermatocelectomy or epididymectomy. There have been no untoward effects associated with this technique and this technique is applicable to a wide variety of scrotal procedures. The method described is simple, rapid to perform, comfortable for the patients and most effective to prevent postoperative complications in patients undergoing a scrotal operation.

[Nonsurgical and endoscopic therapy in obstructive azoospermia].

The endoscopic therapy has an elective role in the distal obstructive azoospermia for urogenital carrefour pathologies both organics and functional and differently in the resection and/or aspiration with sperm recovery forms. Resolutely attends to the symptomatology and positively to the fertility re-establishment, in front of a short sickness-rate. The Authors describe the different techniques with relative indications, results and complications. Instead medical therapy has a role in the obstructive above all post infection and post inflammatory lesions prevention. Furthermore propose to oneself the goal to improve the seminal quality by the improvement of the semen fertilization capacity and to reduce the affections symptomatology. Finally concurs with the sperm selection techniques to fertility potential wealth.
