[Penile implantation surgery for organic impotence due to radical cystectomy or prostatectomy].

Implantation surgery was performed twelve times in eleven patients with organic impotence, mainly due to radical cystectomy and prostatectomy against malignancy, between March, 1982 and April, 1987. A self-contained type prosthesis (AMS Hydroflex(TM] was used in 7 cases, reservoir type inflatable prosthesis (AMS 700TM) in 2, malleable semirigid type (ESKA-Jonas Silicon Silver(TM) Trimming Tip Version) in 2, and nonmalleable semirigid type (Fuji system Finney type) in 1 case. In the last case, the prosthesis was replaced by AMS Hydroflex 4.5 years later at patient's wish. Excellent results and good patients' acceptance were gained with inflatable-type prosthesis (AMS 700 and Hydroflex) in 7 out of 8 cases (88%), whereas concealment problems were produced by semirigid type prosthesis (Finney and Jonas). Experience with AMS Hydroflex penile implantation is reported for the first time in the Japanese literature. Intraoperatively, it was sometimes difficult to implant a pair of Hydroflex rods into both of the corpus cavernosum. Postoperative perineal pain was almost constantly seen and in one patient, penile edema continued for three weeks and subsided spontaneously in two months. In another patient, the length of the prosthesis (15 cm) was short, and exchange to the longer one (17 cm) was necessary. In this patient, the longer Hydroflex caused erosion of the glans to necessitate its removal on one side. From our experience, the diameter (11 mm) of the Hydroflex seems to be too big for the average Japanese patient. The operative procedures and results of each kind of the prostheses are briefly discussed.

[Value of sclerotherapy in the treatment of certain types of impotence caused by venous leakage].

Certain types of impotence, primary or secondary, are due to an "escape" through the superficial venous network of the penis, connecting distally with the femoral veins. Until now, the treatment was surgical and marred with recurrences. The use of sclerotherapy on these superficial veins enables their "closure" which is elegant, fast, almost painless, effective and inexpensive, leading to the cure of the disorder and a normal erection.

Comparison of Doppler and strain-gauge plethysmography to detect vasculogenic impotence.

Doppler penile-pressure determinations to diagnose vasculogenic impotence require an experienced technician, can be time-consuming, yield inconsistent results and require much penile manipulation. Therefore the authors assessed and compared strain-gauge plethysmography as an alternative noninvasive procedure. Sixty-one patients with erectile failure had penile blood pressure determined by Doppler and indium-gallium alloy in Silastic strain-gauge plethysmography. Penile brachial indices were calculated. Strain-gauge results agreed with the Doppler measurements in all but three patients whose indices were found to be normal by Doppler and borderline by strain-gauge plethysmography. The sensitivity, accuracy and specificity of strain-gauge plethysmography were 93%, 95% and 100% respectively. Doppler determinations required an average of 20 minutes to perform, strain-gauge measurements only 4. The authors conclude from this study that strain-gauge plethysmography is a rapid, reliable, accurate method of determining penile blood pressures.

Diabetes-related impotence and its treatment in the middle-aged and elderly: Part I.

Diabetes-related impotence is commonly noted within 10 years of the onset of diabetes. It is frequently due to microangiopathy and is associated with symptomatic neuropathy. Careful history-taking, physical examination, laboratory tests, and frequently, sophisticated diagnostic tests are indicated in the evaluation of these patients. Nocturnal penile tumescence and rigidity testing has become the gold standard of noninvasive evaluation.

[Intracavernous injection of papaverine hydrochloride for impotence in patients with spinal cord injury].

Twenty-one intracavernous injections of 40 or 60 mg papaverine hydrochloride were given to ten male paraplegics. Erection sufficient for coitus was achieved within a few minutes after 15 of the injections (71.4%). Tumescence of the penis lasted from 18 minutes to 48 hours and the penile tumescence of the patients who had reflective erection usually lasted longer than that of the patients who did not. The trial that lasted for 48 hours resulted in the fracture of the penis that was presumed to have occurred during coitus and it was treated operatively. Intracavernous injection of papaverine hydrochloride is available for the impotence of male paralegics, but both doctor and patient must be careful about the sensory disturbance of the penis to avoid penile injury during erection. Further studies are needed to establish safety and long-term efficacy, as well as to determine if histological change of cavernous body occurs by repeated injection.

Advances in the assessment of organic causes of impotence.

There are few adequate studies on the causes of impotence. Nevertheless many clinicians continue to assert that up to 90% of cases are of psychosocial origin. It is slowly becoming apparent that psychosocial causes are just one of many diverse possibilities.

An updated approach to correcting impotence in elderly men.

A myth about transurethral prostatectomy is that it renders the patient unable to achieve an erection. There is no evidence that this is so, nor any evidence that prostatic hypertrophy itself causes impotence. It is imperative that the patient understand what the prosthesis will and will not do for him. All currently available devices provide a penile shaft rigid enough for intromission, but because all devices occupy only the corpora cavernosa, the erect penis will not be as long or as great in circumference as the patient's physiologic erections once were.

[Psychological theories and treatments of erectile impotence].

The conceptual inaccuracies and the diagnostic difficulties encountered in the study of erectile impotence are underlined by the author. After a review and critique of the psychoanalytical and behavioral trends, of the "new sex therapy" and of cognitivism, the therapeutic methods which derive from these concepts are compared with each other. A particular attention is devoted to anxiety since its definition and prevalence varies considerably in the literature despite a misleading superficial similarity.

Histological changes in the penis of the Chacma baboon--a model to study aging penile vascular impotence.

Light and scanning electron microscopy was performed on the penes of Chacma baboons to establish their suitability as animal model for studying vascular impotence. Analogous aging penile vascular changes were found in man, and a fibrous trabeculopathy with intertrabecular senechiae was demonstrated. Considering the corresponding changes, the Chacma baboon could thus be regarded suitable for studying the pathophysiology of aging penile vascular changes.

[Treatment of organic impotence. Self-administered intracavernous injection of papaverin HCI (a preliminary report)].

Intracavernous injection of 40 mg papaverin HCI caused erection sufficient for intromission in all six cases of organic impotence. The patients were taught to self inject one corpus cavernosum just prior to coitus and reported that they were able to have coitus at home. No complications were encountered. This method should be tried first as an alternative to penile implant for patients with organic erectile failure.

Evaluation of impotence in older men.

Careful evaluation was carried out in 93 men older than 50 with erectile dysfunction. Their mean age was 61 years and the disorder had been present for a mean of 4.5 years. While 14 men (15%) had psychosocial factors that may have been pertinent, only 2 scored poorly on an Affect Balance Scale and 3 were receiving psychoactive medications. Results of nocturnal penile tumescence were abnormal in 91%. In 39% penile-brachial pressure indices were suggestive of pelvic vascular disease and in 9% were consistent with a pelvic "steal syndrome." Pelvic or peripheral nerve conduction disorders were also commonly seen in 54%. Endocrinopathy may have contributed to the dysfunction in 35%. Twenty-one men had diabetes mellitus, two new cases of hypothyroidism were discovered and hypogonadism was diagnosed definitely in four and considered likely in five others. Coexisting medical conditions were found in more than 90% of the men, especially hypertension, use of antihypertensive medications and atherosclerotic disease. Previous prostatectomies (19%) and vasectomies (30%) were common in the surgical histories. Given the wide range of disorders uncovered in older men complaining of impotence, diagnostic study of potential causes may lead to a more rational approach for the evaluation and management of these men.

[A new case of impotence after stripping].

Impotence following venous stripping has been rarely reported in the French of Anglo-Saxon literature. The authors report a new case, which was investigated by means of a full psychological, clinical and paraclinical survey. The aetiology appears to be related to the intra-operative ligation of the external pudendal artery, an hypothesis which has already been proposed, but without any objective evidence. The authors describe, for the first time, a simple and original methodology of selective compression to be performed routinely during Doppler flow studies of the penile arteries, which greatly increases the quality and the reliability of the information obtained.

[Hydraulic penile prostheses in the surgery of impotence. Our experience in 20 cases with a 2-year follow-up].

The authors report their experience of the implantation of inflatable penile prostheses in the surgical management of impotence. They have implanted twenty prostheses with a followup of two years to three months. The overall results are very satisfactory in terms of the quality of the sexual life of the couple (85%). On the other hand, the postoperative morbidity rate is high, with 40% of complications including 20% requiring reoperation.

[Exploration of a virile but impotent patient: the clinical interview].

Erectile impotence results of summation of organic, psychological and relational factors. That is why we will have to practice clinical examinations, to ask for complementary investigations (plasmatic prolactinemia, Doppler, plethysmography of night penile erections, and if necessary, selective pelvian arteriography), and more over, to have a clinical interview, as well with the patient, as with his partner. It is this last aspect of the question which will more particularly hold our attention.

[Correction of erectile impotence of venous origin using detachable balloons and coils].

The authors review a radiological classification of venous impotence and report their therapeutic approach. 13 patients with a venous insufficiency of Santorini's plexus were treated by detachable balloons and coils. This technic was convenient in 11 of the 13 cases. 5 patients with a superficial venous insufficiency were treated by embolization by coils. The results in this group appear to be good in 4 cases.

[The value of arteriography in the diagnosis and treatment of post-traumatic secondary impotence (author's transl)].

Angiographic investigations in 9 patients with partial or total post-traumatic secondary impotence present for several years, confirmed the presence of traumatic vascular lesions involving, in nearly all cases, the artery of the penis or its branches (cavernous and bulbar arteries). Selective angiography of the pudendal arteries was able to guide treatment in 5 of these patients. Epigastrocavernous anastomoses, according to the microsurgical procedure developed by Michal, were performed with excellent results in 3 cases.

Impotence in bulls due to vascular shunts from the corpus cavernosum penis.

Eleven bulls were determined to be impotent due to vascular shunts from the corpus cavernosum penis to the extracorporeal circulation. Clinically, the bulls were unable to achieve erection when stimulated with an electroejaculator and in natural breeding trials. The vascular shunts were located by serial contrast radiography of the corpus cavernosum penis. Surgical correction of the shunts was attempted in 8 of the bulls by wedge resection of the tunica albuginea. In 4 bulls, the surgical correction was successful and the bulls were returned to service.

Morphologic changes in the arterial bed of the penis with aging. Relationship to the pathogenesis of impotence.

The arterial vascular bed of the penis has been studied histologically in postmortem material from 30 males in the age range 19 to 85 years, mean 57. Fifteen of these propositi had had diabetes mellitus of average duration of 13 years. In all males more than 38 years old, there was fibrous substitution of the longitudinal smooth muscle in the Ebner pads. Later this was complemented by fibrous proliferation of the intima, medial fibrosis, calcification, and narrowing of the lumen to obilteration from thrombi. The extent of the pathology was apparently related to both age and diabetes mellitus. The nature and extent of the changes indicate that they must necessarily lead to a limitation of the basic function of this arterial tree, i.e., to increase essentially the flow of blood to the cavernous bodies at the time of the erection. These changes can play a decisive role in explaining impotence that occurs with aging, particularly in diabetics.
