[Andrologic surgery].

The need of an economic and social low costs drive more and more surgeons towards the day surgery. The always growing diffusion of local anesthetic supports this trend. The drugs used as local anaesthetics are: carbocaine, procaine, lidocaine and bipivacaine.

[Surgical therapy of obstructive azoospermia: microsurgery].

Microscopic procedures for therapy of obstructive azoospermia or of vasectomy reversals have resulted in accurate reapproximation of ductal structures. The success of vasovasostomy appears to be influenced by the length of time that has passed since the vasectomy was performed or the obstruction become. Failures of vasovasostomy may be attributed to anastomotic stenosis, sperm antibodies, epididymal dysfunction, or an unrecognized epididymal tubule blowout with subsequent obstruction.

[Seminal obstructions of the inflammatory origin].

Presence of bacteria in the sperm is often associated to a reduction of fertility in relationship with a decrease in number and motility of spermatozoa and with an augmentation of the abnormal spermatic cells. In the most severe cases, chronic and complicated phlogosis may lead to obstruction of seminal pathways with consequent azoospermia. Clinical features of seminal phlogosis are extremely variable both in acute and chronic evolutions.

[New trends in the surgical treatment of penile carcinoma].

With the current oncological emphasis on radical treatment allied to minimal invasiveness, choice of treatment relies on precise clinical staging. The corpora cavernosa of the penis represent a well defined anatomical structure distinct from the corpus spongiosum and the glans which are tightly connected to one another. In case of primary penile tumour the T.
