[Cryptorchidism and fertility: evaluation in adult age].

Impairment of fertility rate has been found to be associated with cryptorchidism. In this study we assessed the fertility of 172 adult subjects with unilateral and bilateral cryptorchidism who underwent surgical correction in pediatric age. Fertility has been evaluated by sperm analysis. Moreover test of function of spermatozoa membrane (swelling-test) and the research of antisperm antibodies (spermmar test) were carried out. The report presents data demonstrating that the fertility rate in patients with bilateral cryptorchidism is markedly reduced if compared with subjects affected by unilateral cryptorchidism. Azoospermia is present in 18% of bilateral cryptorchidism. The timing of surgery and the anatomical position of the cryptorchid testes do not seem to affect the fertility rate.

[Cryptorchidism: anomalies of the secretory ducts and azoospermia].

A range of epididymal and vasal anomalies (EVA), varying from ductal patency aberrations to abnormal attachments of the epidydimis to the testis or even complete absence, exists in boys with cryptorchidism, but there are few studies of normal controls for comparison. In the present study anatomy of testicular-epididymal relationships were recorded in 517 cryptorchid patients (423 unilateral and 94 bilateral) and in 192 boys who underwent inguinal exploration for inguinal hernia or hydrocele. The postmortem anatomic relationship of the testis and epididymis in 50 adults was also examined. The operative findings were divided into two groups: simple variants of normal and forms of complete anatomic disconnection of the spermatic ducts (EVA). We were unable to find EVA in the control groups. In contrast EVA was present in the 20% of cryptorchid patients. The incidence was 16.5% in unilateral cryptorchidism and 26% in bilateral cases, in 17% of whom the EVA was bilateral. According to the literature and our previous study azoospermia is present in about 18-20% of adults operated upon in childhood for bilateral cryptorchidism. Our present study may suggest that azoospermia in adults operated on for bilateral cryptorchidism could be partially related to some forms of bilateral occlusion or interruption of the spermatic ducts.

[Non-palpable testis: modern diagnostic and therapeutic trends].

Management of the nonpalpable testis is controversial and can be difficult as shown by the multiple modalities for evaluation and proposed treatment. In our opinion, laparoscopy is the ideal first step in the management of patients with a nonpalpable testis, having a great reliability in locating or confirming absence of an occult testis. Accurate preoperative assessment and localization will assist in selecting the appropriate surgical approach either laparoscopic, laparoscopic-assisted, or open procedure. Laparoscopy was performed on 74 patients with 86 nonpalpable testis. The technique has been demonstrated to be extremely safe and lead to diagnosis in 100% of cases. Surgical management of nonpalpable testis was directly performed by laparoscopy identifying intra-abdominal vanishing testis and locating an intra-abdominal or inguinal testis. The two-stage Fowler-Stephens orchiopexy was performed in 41 patients. The first stage consisted of laparoscopic clip ligation of the spermatic vessels. Of these, 32 underwent the second stage by vas-based orchiopexy; all testes, but one, showed a normal size and consistency. To conclude, we advocate the use of laparoscopy in all boys with nonpalpable testis.

[Progress in the surgical treatment of congenital and acquired broncho-pulmonary pathology].

Surgery is the cornerstone in the management of congenital bronchopulmonary diseases. This term include a wide spectrum of malformative anomalies subdivided clinically into cystic and solid lesions. Bronchogenic cyst (BC), cystic adenomatoid malformation (CAM) and congenital lobar overinflation (CLO) are congenital cystic lesions. Pulmonary sequestration (PS) and pulmonary arteriovenous malformation (PAM) are congenital solid lesions. As a group, congenital bronchopulmonary diseases require removal in order to reduce potentially life-threatening infection and respiratory distress. Bronchopulmonary infections and neoplasms constitutes acquired bronchopulmonary diseases. Improvement in antibiotic therapy has reduced the place of surgery in the current treatment of bronchopulmonary infections. At present, the failure of medical therapy and the appearance of complications are the most common indications for operative treatment. Although these problems are not as common now, at times they required surgical intervention. Finally bronchopulmonary neoplasms are unusual in the pediatric age group. As a result, experience with the diagnosis, management and prognosis is limited. However, the complete surgical resection offers the best chance for survival in the large majority of cases.
