Quantitative peritoneal lavage in evaluating acute abdominal pain of gynecological origin.

This study was performed in order to determine the value of assessing the volume of intraperitoneal fluid, the leucocyte count and the corrected leucocyte count in the peritoneal lavage in patients with acute abdominal pain of gynecological origin. Peritoneal lavage using the dye-dilution technique with Evans-Blue-Human Serum Albumin complex (EBA) as a marker was performed. It was found that an exudate volume of above 250 ml is highly suggestive of an intraperitoneal inflammatory process. The concentration of leucocytes and the corrected leucocyte count in the returned lavage fluid were found to be less reliable indicators of an inflammatory process in the peritoneal cavity than precise determination of the intraperitoneal exudate. It may be concluded that peritoneal lavage with EBA can be a useful adjunct in the evaluation of patients with acute abdominal pain of gynecological origin.

Fine needle aspiration of the testis and correlation with testicular open biopsy.

The diagnostic value of cytologic examination of aspiration biopsy smears was compared with that of histologic examination of surgically removed biopsy specimens from 54 testes in 32 men with oligoazoospermia. In 47 testes (87.1%) a good correlation was found between the results of the two methods: 20 cases had normal testicular morphology, 10 cases had spermatogenic arrest, and 17 had only Sertoli cells. In the remaining seven cases there was a paucity of cells, not permitting a cytologic diagnosis. FNA of the testis is a reliable and simple method of evaluating male infertility.

The use of epididymal fine-needle aspiration for the diagnosis of male genital tract obstruction.

Epididymal fine-needle aspirations (EFNA) were performed on 29 epididymides of 17 infertile, azoospermic men in whom testicular cytology revealed adequate spermatogenesis. Sonograms confirmed the presence of all the excretory male organs. EFNA was performed to diagnose and locate the site of genital tract occlusion. The presence of cuboidal epithelial cells in the aspirate was the sole indication that epididymal content was aspirated. In 10 (34%) of the 29 aspirates there were only cuboidal epithelial cells and no spermatozoa, indicating proximal occlusion in the rete testis, in the canaliculi efferentes or in the most proximal segment of the epididymis itself. Occlusion in the distal segment of the epididymis or in the vas deferens was diagnosed in 13 epididymal aspirates (45%) which contained both cuboidal cells and spermatozoa. From 6 epididymides (21%) no conclusion could be reached because of failed aspirations. There are a variety of treatment modalities available for male genital tract obstruction, such as reconstructive surgery or assisted reproductive technology using sperm aspiration technique. The success rate of treatment is mainly dependent on the site of obstruction. Since vasography has its own limitations and hazards, diagnostic EFNA should be performed before treatment in men in whom genital obstruction is suspected.
