Summary of the recommendations on sexual dysfunctions in men

INTRODUCTION Sexual health is an integral part of overall health. Sexual dysfunction can have a major impact on quality of life and psychosocial and emotional well-being. AIM To provide evidence-based, expert-opinion consensus guidelines for clinical management of sexual dysfunction in men. METHODS An international consultation collaborating with major urologic and sexual medicine societies convened in Paris, July 2009. More than 190 multidisciplinary experts from 33 countries were assembled into 25 consultation committees. Committee members established scope and objectives for each chapter. Following an exhaustive review of available data and publications, committees developed evidence-based guidelines in each area. Main Outcome Measures.  New algorithms and guidelines for assessment and treatment of sexual dysfunctions were developed based on work of previous consultations and evidence from scientific literature published from 2003 to 2009. The Oxford system of evidence-based review was systematically applied. Expert opinion was based on systematic grading of medical literature, and cultural and ethical considerations. RESULTS Algorithms, recommendations, and guidelines for sexual dysfunction in men are presented. These guidelines were developed in an evidence-based, patient-centered, multidisciplinary manner. It was felt that all sexual dysfunctions should be evaluated and managed following a uniform strategy, thus the International Consultation of Sexual Medicine (ICSM-5) developed a stepwise diagnostic and treatment algorithm for sexual dysfunction. The main goal of ICSM-5 is to unmask the underlying etiology and/or indicate appropriate treatment options according to mens and womens individual needs (patient-centered medicine) using the best available data from population-based research (evidence-based medicine). Specific evaluation, treatment guidelines, and algorithms were developed for every sexual dysfunction in men, including erectile dysfunction; disorders of libido, orgasm, and ejaculation; Peyronies disease; and priapism. CONCLUSIONS Sexual dysfunction in men represents a group of common medical conditions that need to be managed from a multidisciplinary perspective.

The role of adjunctive nephrectomy in patients with metastatic renal cell carcinoma.

The results of therapy for 78 patients with disseminated renal cell carcinoma are evaluated. Symptoms related to the primary tumor were noted in only 28 per cent of the patients and were not difficult to manage in those patients not undergoing nephrectomy. Adjuctive nephrectomy, therefore, is a more appropriate term than palliative nephrectomy when referring to removal of the primary tumor as part of an aggresive combined therapeutic approach. Of patients receiving an adjunctive nephrectomy those with osseous metastases only had a better 1-year survival rate (36 per cent) than those with metastases to other sites (18 per cent). Complete regression of metastases was noted in 12 per cent of patients treated with medroxyprogesterone acetate and adjunctive nephrectomy. The role of adjunctive nephrectomy combined with embolic infarction, hormonal therapy, chemotherapy and/or immunotherapy is discussed.

Conservative surgery for renal cell carcinoma: a single-center experience with 100 patients.

From January 1956 to March 1987, 100 patients underwent a conservative (parenchyma-sparing) operation as curative treatment for renal cell carcinoma at our clinic. This series includes 56 patients with bilateral (28 synchronous and 28 asynchronous) and 44 with unilateral renal cell carcinoma; in the latter category the contralateral kidney was either absent or nonfunctioning (17 patients), functionally impaired (17), involved with a benign disease process (6) or normal (4). The pathological tumor stage was I in 75 patients, II in 9, III in 10 and IV in 6. A nephron-sparing operation was performed in situ in 86 patients and ex vivo in 14. Postoperatively, 93 patients experienced immediate function of the operated kidney, while 7 required dialysis (4 temporary and 3 permanent). The incidence of dialysis was greater after ex vivo than in situ surgery (p equals 0.0005). The mean postoperative serum creatinine level in 97 patients with renal function was 1.7 mg. per dl. (range 0.9 to 4.6 mg. per dl.). The over-all actuarial 5-year patient survival rate in this series is 67 per cent including death of any cause and 84 per cent including only deaths of renal cell carcinoma. Survival was improved in patients with stage I renal cell carcinoma (p less than 0.05). Survival also was improved in patients with unilateral renal cell carcinoma (p less than 0.05) and fewer patients in this category had recurrent disease postoperatively (p less than 0.0005). Nine patients (9 per cent) had local tumor recurrence postoperatively and 5 of these were rendered free of tumor by secondary surgical excision. Conservative surgery provides effective therapy for patients with localized renal cell carcinoma in whom preservation of renal function is a relevant clinical consideration.

Clinical guidelines panel on erectile dysfunction: Summary report on the treatment of organic erectile dysfunction

PURPOSE The American Urological Association convened the Clinical Guidelines Panel on Erectile Dysfunction to analyze the literature regarding available methods for treating organic erectile dysfunction and to make practice recommendations based on the treatment outcomes data. MATERIALS AND METHODS The panel searched the MEDLINE data base for all articles from 1979 through 1994 on treatment of organic erectile dysfunction and meta-analyzed outcomes data for oral drug therapy (yohimbine), vacuum constriction devices, vasoactive drug injection therapy, penile prosthesis implantation and venous and arterial surgery. RESULTS Estimated probabilities of desirable outcomes are relatively high for vacuum constriction devices, vasoactive drug injection therapy and penile prosthesis therapy. However, patients must be aware of potential complications. The outcomes data for yohimbine clearly indicate a therapy with marginal efficacy. For venous and arterial surgery, based on reported outcomes, chances of success do not appear high enough to justify routine use of such surgery. CONCLUSIONS For the standard patient, defined as a man with acquired organic erectile dysfunction and no evidence of hypogonadism or hyperprolactinemia, the panel recommends 3 treatment alternatives: vacuum constriction devices, vasoactive drug injection therapy and penile prosthesis implantation. Based on the data to date, yohimbine does not appear to be effective for organic erectile dysfunction and, thus, it should not be recommended as treatment for the standard patient. Venous surgery and arterial surgery in men with arteriolosclerotic disease are considered investigational and should be performed only in a research setting with long-term followup available.

Role of viagra after radical prostatectomy

OBJECTIVES To determine whether the response to sildenafil citrate (Viagra) in patients with erectile dysfunction after radical prostatectomy was influenced by the presence or absence of neurovascular bundles, the interval from surgery to the initiation of drug therapy, and the dose of the drug. METHODS Baseline and follow-up data from 91 patients presenting with erectile dysfunction after radical prostatectomy were obtained. The patients were stratified according to the type of nerve-sparing (NS) procedure: bilateral NS, unilateral NS, and non-NS. They were interviewed using the Cleveland Clinic Post Prostatectomy (CCPP) questionnaire and the International Index of Erectile Function (IIEF) questionnaire. RESULTS The presence or absence of the neurovascular bundles influenced the ability to achieve vaginal intercourse. In the patients who had undergone bilateral NS, 71.7% (38 of 53) responded; in those with unilateral NS, 50% (6 of 12) responded; and in those with non-NS, 15.4% (4 of 26) responded. The IIEF questionnaire confirmed the quality of the positive responses, with significant improvements in response to question 3 (frequency of penetration), question 4 (frequency of maintenance of erection), and question 7 (satisfaction with intercourse). The magnitude of improvement in responses was higher in the bilateral NS group than in the unilateral NS and non-NS groups (P <0.05). When the data of the 48 positive responders were analyzed, no difference in the response rate was found when the interval from surgery to drug therapy was stratified by the following three intervals: 0 to 6 months (44%), 6 to 12 months (55%), and greater than 12 months (53%). Of the positive responders, 14 (29.1%) required the 50-mg dose, and 34 (70.9%) required the 100-mg dose. The most common side effects were transient headaches (28.6%), flushing (21.9%), dizziness (8.8%), dyspepsia (6.5%), and nasal congestion (5.4%), with an increase in the incidence of headaches seen at the higher dose (P = 0.04). CONCLUSIONS Successful treatment of erectile dysfunction with sildenafil citrate after radical prostatectomy depends on the presence of the neurovascular bundles. Our data suggest that the response to sildenafil is not related to the interval between the surgery and initiation of drug therapy but is related to the dose.

Early use of vacuum constriction device following radical prostatectomy facilitates early sexual activity and potentially earlier return of erectile function

To assess the efficacy of vacuum constriction devices (VCD) following radical prostatectomy (RP) and determine whether early use of VCD facilitates early sexual activity and potentially earlier return of erectile function. This prospective study consisted of 109 patients who underwent nerve-sparing (NS) or non-nerve-sparing (NNS) RP between August 1999 and October 2001 and developed erectile dysfunction following surgery. The patients were randomized to VCD use daily for 9 months (Group 1, N=74) or observation without any erectogenic treatment (Group 2, N=35). Treatment efficacy was analyzed by responses to the Sexual Health Inventory of Men (SHIM) (abridged 5-item International Index of Erectile Function (IIEF-5)), which were stratified by the NS status. Patient outcome regarding compliance, change in penile length, return of natural erection, and ability for vaginal intercourse were also assessed. The mean patient age was 58.2 years, and the minimum follow-up was 9 months. Use of VCD began at an average of 3.9 weeks after RP. In Group 1, 80% (60/74) successfully used their VCD with a constriction ring for vaginal intercourse at a frequency of twice/week with an overall spousal satisfaction rate of 55% (33/60). In all, 19 of these 60 patients (32%) reported return of natural erections at 9 months, with 10/60 (17%) having erections sufficient for vaginal intercourse. The abridged IIEF-5 score significantly increased after VCD use in both the NS and NNS groups. After a mean use of 3 months, 14/74 (18%) discontinued treatment. In Group 2, 37% (13/35) of patients regained spontaneous erections at a minimum follow-up of 9 months after surgery. However, only four of these patients (29%) had erections sufficient for successful vaginal intercourse and rest of patients (71%) sought adjuvant treatment. Of the 60 successful users, 14 (23%) reported a decrease in penile length and circumference at 9 months (range, 4–8 months) compared to 12/14 (85%) among the nonresponders. However, in control group 22/35 reported decrease in penile length and circumference. Early use of VCD following RP facilitates early sexual intercourse, early patient/spousal sexual satisfaction, and potentially an earlier return of natural erections sufficient for vaginal penetration.

LONG-TERM CONTINENCE AND PATIENT SATISFACTION AFTER ARTIFICIAL SPHINCTER IMPLANTATION FOR URINARY INCONTINENCE AFTER PROSTATECTOMY

PURPOSE We assess long-term continence and patient satisfaction after implantation of the AMS Sphincter 800 (American Medical Systems, Minnetonka, Minnesota) in men who were incontinent after total and subtotal prostatectomy. MATERIALS AND METHODS Patients who had an artificial urinary sphincter implanted for urinary incontinence after prostatectomy and a minimum of 20 months of followup were identified from a patient database. The medical records of these 209 patients were reviewed, and a questionnaire was mailed. Telephone contact was attempted with patients who did not respond to the questionnaire. Of the 209 patients 11 (5%) had undergone device removal, 34 (16%) were deceased and an additional 51 (24%) could not be contacted for followup. Our study group consisted of the 113 patients with artificial urinary sphincters who could be contacted for followup. Mean followup was 73 months (range 20 to 170). RESULTS There were 4 (4%) patients who were dry and continent and 68 (60%) were incontinent using 0 to 1 pad daily. An additional 35 (31%) patients required 2 to 3 pads daily and 5 (4%) used more than 3 daily. There were 14 (12%) patients who had undergone surgical revision of the device. Of the 113 patients 31 (28%) were very satisfied, 50 (45%) satisfied, 20 (18%) neutral, 7 (6%) dissatisfied and 4 (4%) very dissatisfied. One patient was not using his device to control continence. CONCLUSIONS Artificial urinary sphincter implantation offers men who are incontinent after prostatectomy a reasonable chance for obtaining long-term satisfactory urinary control, although complete continence is unusual.

Intracavernous injection therapy: Analysis of results and complications

Experience with 100 patients who used intracavernous injection therapy with a combination of papaverine with or without phentolamine for 29 months is analyzed in detail. The largest group of patients had vasculogenic erectile failure (56%). At the end of followup 50% of the patients were no longer performing injection. Those who discontinued injection therapy were slightly older and had more vasculogenic erectile failure. The nonfibrotic complications were mild in all instances and did not result in discontinuation of injection therapy. These complications consisted of small hematomas in 20.9% of the patients, mild discomfort in 13.6% and mild liver enzyme abnormalities in 9.8%. No episode of priapism or infection occurred during therapy. Fibrotic complications consisted of nodules or plaques, and correlated significantly with the number of months on injection and the number of injections. At 12 months the fibrotic complication rate was 31 +/- 8.6%. Our study suggests caution regarding the long-term complication rate of intracavernous injection therapy with these compounds and underscores the importance of routine followup examinations. While injection therapy is an effective form of treatment for erectile failure, it is not a satisfactory alternative for many patients and is associated with a significant fibrotic complication rate.

Review of cleveland clinic experience with penile fracture

OBJECTIVES Fracture of the penis is an uncommon injury that results from trauma to the erect penis, usually during sexual intercourse. In some cases, the urethra is injured as well. To determine the outcome of immediate surgical management, we reviewed the cases of 8 patients with fracture of the penis who presented to the Cleveland Clinic from 1992 to 1998. METHODS Trauma was encountered during intercourse in all our patients. A concomitant urethral injury was found in 3 cases (38%); 1 was a complete disruption, and the other 2 were partial injuries. Patients were treated with immediate surgical exploration and repair, with preoperative urethrography in patients suspected of having a urethral injury. RESULTS All patients had a successful outcome, with preservation of sexual function and without significant penile curvature. Patients with urethral injuries reported normal voiding without the need for additional procedures. CONCLUSIONS Immediate surgical repair offers complete recovery for patients with penile fracture in most cases, even in the presence of urethral injury. We present our recommendations for treatment of this condition.

Implants, Mechanical Devices, and Vascular Surgery for Erectile Dysfunction

INTRODUCTION The field of erectile dysfunction (ED) is evolving and there is a need for state-of-the-art information in the area of treatment. Aim. To develop an evidence-based, state-of-the-art consensus report on the treatment of erectile dysfunction by implants, mechanical devices, and vascular surgery. METHODS To provide state-of-the-art knowledge concerning treatment of erectile dysfunction by implant, mechanical device, and vascular surgery, representing the opinions of 7 experts from 5 countries developed in a consensus process over a 2-year period. MAIN OUTCOME MEASURE Expert opinion was based on the grading of evidence-based medical literature, widespread internal committee discussion, public presentation, and debate. RESULTS The inflatable penile prosthesis (IPP) is indicated for the treatment of organic erectile dysfunction after failure or rejection of other treatment options. Comparisons between the IPP and other forms of ED therapy generally reveal a higher satisfaction rate in men with ED who chose the prosthesis. Organic ED responds well to vacuum erection device (VED) therapy, especially among men with a suboptimal response to intracavernosal pharmacotherapy. After radical prostatectomy, VED therapy combined with phosphodiesterase type 5 therapy improved sexual satisfaction in patients dissatisfied with VED alone. Penile revascularization surgery seems most successful in young men with absence of venous leakage and isolated stenosis of the internal pudendal artery following perineal or pelvic trauma. Currently, surgery to limit venous leakage is not recommended. CONCLUSIONS It is important for the future of the field that patients be made aware of all treatment options for erectile dysfunction in order to make an informed decision. The treating physician should be aware of the patients medical and sexual history in helping to guide the decision. More research is needed in the area of revascularization surgery, in particular, venous outflow surgery.
