After having emphasized the importance of interdisciplinary diagnostic approach to the sexual impotence as a symptom and having made some comments about the erection's physiology, the Authors, according to their experience, take drugs into consideration for elective treatment of sexual intercourse.
Surgical therapy is the only useful correction in congenital fibrosis or in hypoplasia of the 'corpora cavernosa', associated with hypospadia or not. On the contrary in not congenital fibrosis of the 'corpora cavernosa' (Peyronie's disease, consequences of priapism, or trauma, complications of pharmaco-prosthesis) are allowed pharmaco-physical treatments (infiltrations, ionophoresis, ultrasound, laser). Pharmaco-physical therapy can be used as the only treatment, which is often resolutive, but it is also useful before or after the surgical operation of the 'corpora cavernosa'. These diseases can give disorders of the erection, until complete impotence is reached. In fact the erectile tissue can't expand, because of the rising fibrosclerosis. Among acquired fibrosis of corpora cavernosa I.P.P. has surely the greatest recurrent: the consistency of our series made possible to achieve significant results with a unified therapeutical protocol. The same management was applied in other, less frequent, penile fibrosis, always with full positive results even if on a small number of patients. We are evaluating a new drug (defibrotide) in the treatment of cavernosal vasculitis. Another one (hyaluronidase) associated to orgotein, could improve its effect against inflammation especially in chronic evolutions. Besides new treatments, we emphasize the prevention of iatrogenic fibrosis with particular regard to cavernous pharmaco-infusions by autoinjections: the training of the patient and the safety of the autoinjectors must be carefully checked by the andrologist to decrease a large amount of complications.
In the therapy of vasculogenic impotence, the Vacuum Device has been proposed up to now as an "external" prosthesis device with the aim of obtaining a penile erection of sufficient rigidity for penetration, in patients afflicted by vascular or neurological disorders. In the eighties, the experience gained with the use of Intra Cavernous Injections (C.I.D.) (using papaverine, phentolamine and prostaglandin), demonstrated not to be an exclusively palliative therapy ("pharmacological prosthesis"), but to represent as well a sort of "vasoactive exercise" of the erectile tissue. In the nineties, many wondered what could be a valid alternative to the C.I.D. Taking this into consideration, we modified the method of application of Vacuum Therapy. The device was used once a day without the constrictive band applied to the penis root, in order to generate a passive action on the erectile tissue, a sort of "stretching" for the smooth muscle fibers. From January 1990 to December 1991, we treated 78 pts. afflicted by erectile failure. The patients were divided into 3 groups (26 each) of distinct therapy: the first was treated weekly with only endocavernous papaverine administration (20 mg.), the second underwent daily Vacuum Therapy exclusively (10'-15') and the third received a combined therapy: Vacuum Device, daily and C.I.D. with Papaverine (20 mg.) once a week. The results of this treatment are as follows: the patients who underwent Vacuum Therapy daily (2nd and 3rd groups) showed, at the end of the treatment (6 months), a significant improvement in spontaneous erectile ability (14 Pts.-53.8% in the 2nd group; 17 Pts-65.3% in the 3rd group).(ABSTRACT TRUNCATED AT 250 WORDS)
Diagnosis in cryptorchidism should be as early as possible for therapeutical purposes and for the achievement of most positive results. Early but also exact diagnosis allows a selective therapy concerning type of procedure and age of performance. Aims of early diagnosis and selected treatment are: prevention of infertility and eventual decrease of androgenic endocrinal function in the adult; prevention of torsion in retractile testis; prevention of trauma in perineal ectopic situation; prevention of cancer especially in cryptorchidism of the adult; prevention of psychogenic defects of the empty scrotum. Those goals can be obtained by different approaches: pharmacological (hormonal stimulation), surgical (orchidopexy) or by their association. If hormonal administration is not suitable or without results surgical approach will be adopted. Which is now the most suitable age for surgery? Testicular damages begin at the second year of life. Therefore operation should be acted in advance. However, up to date international acknowledgement is in favour of surgical management around the fourth year for the advantages of a more mature anatomical situation without reducing quality of results. Purpose of early diagnosis and selective therapy in cryptorchidism is to avoid irreversibility of severe histological alteration able to compromise gonadal, especially germinal, function. It is never to forget that the high level of infertility in cryptorchidism can be depending not only on evident alteration in number, motility and morphology of spermatozoa but also on morphofunctional defects escaping from the routine seminal examination. All that is in tight connection with the intrinsic dysmorphism in cryptorchism where the abnormal position of the testis is only a partial aspect.(ABSTRACT TRUNCATED AT 250 WORDS)
