Efficacy and safety of transurethral alprostadil therapy in men with erectile dysfunction. MUSE Study Group.

OBJECTIVE: To examine the safety and efficacy of transurethral pharmacotherapy for erectile dysfunction, involving the use of a novel therapeutic system to administer alprostadil (prostaglandin E1) to the urethral mucosa in a double-blind, randomized, parallel, placebo-controlled study conducted in five countries in Europe. PATIENTS AND METHODS: In an outpatient setting, patients with primarily organic erectile dysfunction of at least 3 months' duration were treated with transurethral alprostadil, in an open-label, dose-escalating study. Testing stopped when the dose provided an erection sufficient for intercourse, as assessed by the patient and the investigator. Patients who achieved a sufficient response were then randomized to either active medication at the selected dose or to placebo for use at home for 3 months. After each home administration, patients recorded in diaries whether or not sexual intercourse occurred and any adverse reactions to the drug. RESULTS: A total of 249 patients were treated in an outpatient setting; of these patients, 159 (64%) achieved an erection sufficient for intercourse and were randomized (1:1) to either active medication or placebo for home treatment. Of the patients randomized to alprostadil for home treatment, 69% reported intercourse at least once, compared with 11% of patients randomized to placebo (P < 0.001). The most common adverse reaction, urethral pain/burning, was reported by 7% of patients in the clinic. Most patients (83%) graded transurethral alprostadil as causing minimal or no discomfort in the clinic. No patient reported priapism or developed penile fibrosis. CONCLUSION: Alprostadil delivered transurethrally by this system was well tolerated and effective in treating erectile dysfunction.

The effect of transurethral alprostadil on the quality of life of men with erectile dysfunction, and their partners. MUSE Study Group.

OBJECTIVE: To evaluate the impact of treatment for erectile dysfunction on the quality of life of men and their partners. PATIENTS AND METHODS: The study included 249 men with organic erectile dysfunction of more than 3 months' duration who self-administered transurethral alprostadil in an open-label, dose-escalating manner in an outpatient medical setting. Patients with a sufficient response (159) were randomly assigned in a double-blind protocol to either active medication or placebo for 3 months at home. Patients and partners each completed quality-of-life questionnaires before and after treatment. RESULTS: In the clinic 159 of the 249 men (64%) had an erection sufficient for intercourse when using transurethral alprostadil. At home, 46 of 67 men (69%) reported intercourse at least once on transurethral alprostadil, compared with eight of 73 (11%) on placebo (P < 0.001). Patients on alprostadil showed a 34% improvement in their 'relationship with partner', a 5% improvement in 'personal wellness', and a 71% improvement in 'quality of erection' domains, compared with a decline of 11%, 8% and 1%, respectively, in patients on placebo (P < 0.005 for each comparison). Partners of patients on alprostadil showed a 35% improvement in the 'relationship with partner' domain, compared with a 12% improvement in the placebo group (P = 0.028). There was a trend toward improvement in other partner domains. Urogenital pain was reported by 14% of patients during home treatment. CONCLUSION: The resumption of sexual intercourse with the use of transurethral alprostadil was accompanied by an improvement in several important quality-of-life domains in patients and their partners.

The flare in serum alkaline phosphatase activity after orchiectomy: a valuable negative prognostic index for progression-free survival in prostatic carcinoma.

PURPOSE: We determined whether an early flare in serum alkaline phosphatase activity after orchiectomy was of prognostic value for progression-free survival in patients with advanced prostatic carcinoma. MATERIALS AND METHODS: A retrospective analysis of a data base from a Dutch multicenter study on prostatic carcinoma was done to determine the prognostic value of a flare in alkaline phosphatase activity after orchiectomy in 112 patients with metastatic (75%) or locally advanced (25%) disease. Cox's proportional hazards models and Kaplan-Meier survival curves were used. RESULTS: Of the patients 50% had initially increased alkaline phosphatase levels and a flare in activity was demonstrated in 87% 2 to 4 weeks after orchiectomy. The prostate specific antigen nadir (cutoff 4 ng./ml.) 6 months after orchiectomy was of significant prognostic value for progression-free survival. A flare in alkaline phosphatase activity after orchiectomy demonstrated an early significant prognostic value for progression-free survival, independent of the serum alkaline phosphatase activity. CONCLUSIONS: The simplicity, ready availability and cost-effectiveness of serum alkaline phosphatase activity as a prognostic index render it attractive to the clinician, particularly early in the course of prostatic carcinoma. Measuring the flare in alkaline phosphatase activity within 1 month of orchiectomy may permit early identification of patients in whom the disease is likely to progress rapidly and who would potentially benefit from aggressive treatment.

Discrimination between psychogenic and organic erectile dysfunction.

The aim of this study was to develop a screening test based on the Leiden Impotence Questionnaire (LIQ) in order to assist in the difficult process of differentiating between psychogenic and organic erectile dysfunction (ED). The main sample consisted of 176 patients with ED, which was classified according to the results of the urological and psychiatric assessment as either organic, in 109 (62%) patients, or psychogenic, in 67 (38%) patients. A logistic regression model including six general items from the LIQ correctly identified psychogenic ED in 62% of the cases, and organic ED in 86%, with an overall correct classification rate of 76%. Adding information regarding sexual intercourse and the relationship in patients who had a partner and were having sexual intercourse the correct classification rates were: psychogenic 77%, organic 94%, and overall 87%. Discrimination between psychogenic and organic ED is improved when more information concerning sexual activity can be assessed.

Interconnections of the upper ventral rami of the human sacral plexus: a reappraisal for dorsal rhizotomy in neurostimulation operations.

The extension of a dorsal rhizotomy in bladder stimulation patients is partly determined by connections between the ventral rami of the second, third, and fourth sacral spinal nerves. The literature is inconclusive on interconnections of these ventral rami in the human sacral plexus. The sacral plexuses of ten human cadavers were dissected in this gross anatomy study. In nine cases a branch connecting the ventral rami of the second and third sacral spinal nerves was found. Electron microscopy demonstrated the presence of thick myelinated fibers in this branch. In the male plexuses this branch formed the only link between the second sacral spinal segment and the pelvic plexus. The ventral ramus of the second sacral nerve always contributed to the pudendal nerve, whereas involvement of the ventral rami of the first and third sacral nerves differed individually and intersexually.

A late manifestation of testicular seminoma in the bladder in a renal transplant recipient: a case report.

An unusual case is presented of a renal transplant recipient on immunosuppressive medication who underwent orchiectomy for a testicular seminoma. Since the surgical resection plane showed seminoma cells, radiotherapy was applied to the para-aortic and inguinal regions. Tumor recurred in the bladder 3 years later as demonstrated by urine cytology and later by bladder biopsies. After chemotherapy, repeated bladder biopsies were normal and a complete remission was achieved. The possible metastatic pathways are discussed.

Lethal Fournier's gangrene following vasectomy.

A case is presented of a healthy young man who had Fournier's gangrene after standard bilateral vasectomy. Despite maximal treatment, including extensive necrectomy and broad-spectrum antibiotics, this complication was lethal. To our knowledge a lethal complication of vasectomy has not been reported in the literature.

PIP: A health practitioner performed a standard bilateral vasectomy on a 33-year old male who did not suffer from an immunodepressed state. No complications arose and bleeding was minimal during the vasectomy. 2 days later, he visited a physician with a fever of 39 degrees Celsius and wound reaction. The physician prescribed oral floxacillin, but the following day he suffered acute septic shock and was admitted to a hospital. The incision site was red due to congestion of capillaries, purple, swollen, and painful. Physicians ruled out prostatitis, abscess formation, and a pulmonary source as causes of the fever. The white blood cell count, potassium, creatinine, and glucose levels were very high. Physicians administered parenteral broad spectrum antibiotic treatment (imipenem/cilastatine and metronidazole) even though the blood, urine, and sputum cultures grew no pathogens. They found and evacuated hematoma and necrotic tissue from the vasectomy sites. They placed silicone drains in the sites. Within the next 24 hours, necrosis developed in the scrotum while his clinical condition declined rapidly. He suffered a cardiac arrest. They transported him to the University Hospital in Leiden, the Netherlands where physicians did a necrotomy of the scrotal, penile, and perineal skin and removed both testes. 100 colonies of Streptococcus hemolytic group A, 10-100 colonies of Escherichia coli, and 10 colonies of Staphylococcus epidermidis grew in the cultures of tissue removed at the other hospital. Yet cultures from tissue removed at the University Hospital were negative. No anaerobic bacteria colonies grew. The physicians administered penicillin, ceftazidime, and floxacillin based on antibiotic sensitivity testing results. They also began hemodialysis. 24 hours after necrotomy and bilateral orchiectomy, the necrotizing process had not spread. Yet 13 hours later and 5 days after the vasectomy, the patient succumbed. This case was the 1st known fatal complication of vasectomy. The diagnosis was scrotal gangrene of Fournier.

Metabolic evaluation in stone patients in relation to extracorporeal shock wave lithotripsy treatment.

No information exists in the literature about the optimal time for metabolic evaluation of stone patients in relation to extracorporeal shock wave lithotripsy (ESWL) treatment. It is uncertain whether the presence of a stone, ESWL treatment itself or subsequent colic episodes influence the urinary risk factors. A prospective study was performed to determine the optimal period for metabolic evaluation. Two 24-hour urine samples were collected directly before, and 1 week, 1 month and 3 months after therapy in an outpatient setting and tested for total volume, calcium, uric acid, oxalate, citrate and creatinine levels. A total of 66 patients was available for evaluation. Comparison of the 4 subsequent collecting periods showed no statistically significant differences in the excretion values. Also, in subgroups of patients with colic (16%), on a calcium oxalate restricted diet (12%) and with repeated treatments within 3 months (33%) no differences were noted. This means that the presence of a stone, treatment itself or subsequent colic episodes have no adverse effect on the urinary risk factors. For practical reasons metabolic evaluation directly before ESWL treatment seems most attractive. In the pre-ESWL samples hypercalciuria (greater than 7.5 mmol./24 hours), hyperuricosuria (greater than 6 mmol./24 hours), hyperoxaluria (greater than 0.5 mmol./24 hours) and hypocitraturia (less than 2 mmol./24 hours) were found in 31%, 12%, 18% and 27%, respectively, of the patients. It is concluded that metabolic evaluation before ESWL is practical, applicable and reliable.

Use of open-end Malecot catheter after percutaneous renal surgery.

Use of an open-end nephrostomy tube after renal surgery gives way to the reintroduction of a guide wire in the event a second procedure is needed. The use of a standard Malecot catheter for this purpose is described.

Primary melanoma in the female distal urethra.

A case of primary urethral oligomelanotic melanoma is presented. Melanoma of the female distal urethra is a rare tumor with a poor prognosis. Imprint cytology was used for detection. Electron microscopy and immunohistochemistry were used to confirm the histologic diagnosis.
