摘要:

With the advent of intracavernous injections, pharmacotherapy became the first-line treatment of erectile dysfunction. In the current literature prostaglandin El (PCE1) has been shown to be superior to the other vasoactive substances used for intracavernosal pharmacotherapy.

摘要:

Veno-occlusive insufficiency is a frequent cause of erectile dysfunction whose diagnosis is established by pharmacocavernometry-cavernography. This vascular complaint seems to result in alteration of the intracavernous structures. Selected patients may be treated by resection of the venous network. Further studies on the causes of this dysfunction are necessary to improve the knowledge and treatment of venogenic impotence.

摘要:

Arterial reconstructive surgery is the alternative treatment for those impotent patients who wish the restoration of a normal erection without any mechanical or pharmacologic assistance. Although various operative approaches have been performed since the early 1970s, contemporary procedures are based on modern concepts of the physiology of erection, new diagnostic procedures in the dynamic state and endothelium-sparing vascular and microvascular principles. Success rates have reached 70% in selected patients.

摘要:

The concept of vacuum devices to create an erection is not new but only recently have they been studied scientifically and gained acceptance by the medical community. The vacuum pump draws enough blood into the penis to create an erection and rigidity is maintained with a constricting band or a silicone sheath. These devices produce a satisfactory erection in most patients, appear safe, and represent a viable treatment alternative for selected patients with erectile dysfunction.

摘要:

The era of modern penile implants is concluding its second decade and these devices are still popular options despite competition from other impotence treatment modalities. Mechanical reliability has been very good with current models with repair rates running at about 5% in 5 years. Patient satisfaction with the prosthesis has reached 80–90%.

摘要:

Our ability to diagnose and treat the infertile male is advancing rapidly. Tests of sperm function, such as the sperm penetration assay (SPA) and the hemizona assay (HZA), provide qualitative and quantitative information regarding the fertilizing capacity of the sperm. Understanding these tests, as well as identifying factors that can adversely affect sperm function, are important in the thorough evaluation of the infertile male.

摘要:

Microsurgical epididymal sperm aspiration (MESA) is a novel technique that makes the retrieval of sperm from the obstructed epididymis possible. When combined with advanced reproductive measures, such as in vitro fertilization, pregnancies can be achieved. This raises new questions about the function of the epididymis, once thought to be indispensible for the full maturation of human sperm. Continued research will hopefully lead to even higher conception rates using epididymal sperm while also helping to provide a fuller understanding of the interaction between the epididymis and the spermatozoa that traverse it.

摘要:

This bibliography is compiled by urologists from the journals listed at the end of this publication. It is based on literature entered into our database between 1st June 1990 and 31st May 1991 (articles are generally added to the database about two and a half months after publication). In addition, the bibliography contains every paper annotated by reviewers; these references were obtained from a variety of bibliography databases and published between the beginning of the review period and time pf going to press. The bibliography has been grouped into topics that relate to the reviews in this period and the time of going to press.
