Sildenafil citrate after radical retropubic prostatectomy

PURPOSE Erectile dysfunction continues to be a significant problem for men after radical retropubic prostatectomy despite nerve sparing techniques. Sildenafil citrate (Viagra) has proved effective for erectile dysfunction in many men. We determine the efficacy of sildenafil in men with erectile dysfunction after radical retropubic prostatectomy and examine variables that may impact the response to treatment. MATERIALS AND METHODS A total of 84 men were prescribed sildenafil after radical retropubic prostatectomy and asked to complete a series of questionnaires, including the International Index of Erectile Function (IIEF), on erectile function before and after sildenafil administration. The importance of factors, such as patient age, time since surgery, degree of cavernous nerve sparing, preoperative prostate specific antigen, Gleason score, clinical and pathological stage, and baseline postoperative erectile function, was examined. RESULTS Of the 84 patients 45 (53%) had improved erections and 34 (40%) had improved ability for intercourse while taking sildenafil. Mean IIEF score for the erectile function domain increased from 9 to 14 (p <0.001). Orgasmic function (p = 0.004) and intercourse satisfaction (p = 0.009) also significantly improved. The degree of nerve sparing and baseline postoperative erectile dysfunction had a significant impact on the ability of sildenafil to improve erectile function (p = 0.010 and p <0.001, respectively) and total IIEF questionnaire responses (p = 0.031 and p <0.001, respectively). Age and pathological stage also appeared to have a significant effect. CONCLUSIONS Sildenafil improved erectile function and the ability to have intercourse in more than half of men after radical retropubic prostatectomy. Baseline postoperative erectile function, which is dependent on the degree of nerve sparing technique, significantly impacts the likelihood that patients will respond to sildenafil.

Sling surgery for stress urinary incontinence in women: a systematic review and metaanalysis.

OBJECTIVE Understanding the long-term comparative effectiveness of competing surgical repairs is essential as failures after primary interventions for stress urinary incontinence (SUI) may result in a third of women requiring repeat surgery. STUDY DESIGN We conducted a systematic review including English-language randomized controlled trials from 1990 through April 2013 with a minimum 12 months of follow-up comparing a sling procedure for SUI to another sling or Burch urethropexy. When at least 3 randomized controlled trials compared the same surgeries for the same outcome, we performed random effects model metaanalyses to estimate pooled odds ratios (ORs). RESULTS For midurethral slings (MUS) vs Burch, metaanalysis of objective cure showed no significant difference (OR, 1.18; 95% confidence interval [CI], 0.73-1.89). Therefore, we suggest either intervention; the decision should balance potential adverse events (AEs) and concomitant surgeries. For women considering pubovaginal sling vs Burch, the evidence favored slings for both subjective and objective cure. We recommend pubovaginal sling to maximize cure outcomes. For pubovaginal slings vs MUS, metaanalysis of subjective cure favored MUS (OR, 0.40; 95% CI, 0.18-0.85). Therefore, we recommend MUS. For obturator slings vs retropubic MUS, metaanalyses for both objective (OR, 1.16; 95% CI, 0.93-1.45) and subjective cure (OR, 1.17; 95% CI, 0.91-1.51) favored retropubic slings but were not significant. Metaanalysis of satisfaction outcomes favored obturator slings but was not significant (OR, 0.77; 95% CI, 0.52-1.13). AEs were variable between slings; metaanalysis showed overactive bladder symptoms were more common following retropubic slings (OR, 1.413; 95% CI, 1.01-1.98, P = .046). We recommend either retropubic or obturator slings for cure outcomes; the decision should balance AEs. For minislings vs full-length MUS, metaanalyses of objective (OR, 4.16; 95% CI, 2.15-8.05) and subjective (OR, 2.65; 95% CI, 1.36-5.17) cure both significantly favored full-length slings. Therefore, we recommend a full-length MUS. CONCLUSION Surgical procedures for SUI differ for success rates and complications, and both should be incorporated into surgical decision-making. Low- to high-quality evidence permitted mostly level-1 recommendations when guidelines were possible.

Side-effect profile of sildenafil citrate (Viagra) in clinical practice

OBJECTIVES Sildenafil citrate (Viagra) has been shown to be an effective treatment for erectile dysfunction. Initial studies reported a high tolerability and low incidence of certain characteristic adverse reactions. We sought to evaluate the incidence of side effects of sildenafil citrate, independent of industry support and constraints, utilizing a heterogeneous cohort of patients from a university-based practice. METHODS A prospective, open-label, flexible-dose study of 256 patients treated with sildenafil citrate for erectile dysfunction was performed at a single institution. The patients were questioned explicitly about the occurrence of headache, flushing, dyspepsia, nasal congestion, visual changes, and other side effects. RESULTS The adverse reactions most commonly observed were flushing (30.8%), headache (25. 4%), nasal congestion (18.7%), and heartburn (10.5%). All events were short lived and mild in nature. In the present study, 31.6% of patients experienced one or more adverse events. However, no one withdrew from the study because of the severity of these events. There was a significant association between higher doses and the occurrence of side effects. CONCLUSIONS The incidence of adverse events attributable to sildenafil citrate may be higher than initially reported, but an explanation may be the methodology of data collection and the industry-independent nature of this study. The side-effect profile is dose related and mild. Sildenafil citrate remains a safe and well-tolerated treatment for erectile dysfunction.

Treatment of infertility due to anejaculation in the male with electroejaculation and intracytoplasmic sperm injection.

PURPOSE We tested the hypothesis that spinal cord injury and/or anejaculation affects the outcome of intracytoplasmic sperm injection (ICSI). MATERIALS AND METHODS From November 1993 to October 1998 we obtained and prospectively reviewed data on 34 ICSI cycles using electroejaculated sperm, 620 male factor infertility ICSI cycles using normal ejaculated sperm and 120 cases of obstructive azoospermia, in which microsurgical epididymal aspiration and testicular sperm extraction-ICSI were done in 93 and 27, respectively. RESULTS A total of 34 ICSI cycles were performed in 17 couples with male infertility due to anejaculation secondary to spinal cord injury in 10 patients and retroperitoneal lymph node dissection in 5, and idiopathic in 2. In all 17 couples at least 3 previous intrauterine insemination cycles had failed. After electroejaculation 11 men had oligozoospermia and 6 normal sperm density. Median sperm retrieval volume plus or minus standard deviation was 1.9 +/- 1.9 ml., median sperm concentration 70.7 +/- 60.2 x 106 sperm per ml., median motility 10.7% +/- 10.8% and median forward progression 2.3 +/- 0.5 (scale 1 to 4). In the anejaculation group ICSI resulted in a median fertilization of 60% +/- 28%, 15% pregnancies per cycle and 29% pregnancies per couple. In the control group of 620 ICSI cycles from ejaculated specimens obtained from male patients with infertility median fertilization was 58% +/- 26%, and there were 39% pregnancies per cycle and 47% pregnancies per couple. The rate of pregnancies per embryo transfer and per couple was higher in the control than in the electroejaculation-ICSI group (p <0.05). However, there was no statistically significant difference in the fertilization rate. CONCLUSIONS ICSI or in vitro fertilization is a viable alternative for patients with anejaculation in whom intrauterine insemination failed. While the fertilization rate is similar in these couples, the pregnancy rate is significantly lower than that achieved with ejaculated specimens from patients with severe male factor infertility. ICSI is a viable alternative for a patient with anejaculation in whom intrauterine insemination or in vitro fertilization failed.

Management of the acute abdomen in pregnancy: a review

Purpose of review The acute abdomen remains a challenge for all physicians who take part in the care of women in pregnancy. Obstetricians must be abreast of current topics, especially critical when having to consult other specialties for assistance in managing these conditions. Recent findings We will highlight recent observations in the literature concerning the ability to perform laparoscopy safely in pregnancy, the accuracy of diagnosing appendicitis, and new methods to accurately diagnose urolithiasis with less ionizing radiation effect on the fetus. Finally, with the proficiency of laparoscopy and choledochoscopy improving, we will review several articles underlining their safety. Summary Laparoscopy appears to be well tolerated in pregnancy, but larger multicenter prospective studies are required to make better recommendations concerning its use, with a registry needed to facilitate this endeavor. Conservative management of gallstone pancreatitis may fall out of favor, and choledochoscopy for symptomatic gallstones in the biliary tree may become the treatment of choice. Most cases of urolithiasis resolve with conservative management, but the possibility of preterm labor in these patients must be recognized and newer imaging techniques for diagnosis containing less radiation be used. Adnexal torsion in pregnancy may be another condition that is managed through the laparoscope as the gynecologic communitys laparoscopic skills improve.

Pathological epididymal obstruction unrelated to vasectomy : Results with microsurgical reconstruction

PURPOSE We determine the success of end-to-side epididymovasostomy in patients presenting with obstructive azoospermia from primary epididymal obstruction and identify prognostic factors that could predict a successful outcome. MATERIALS AND METHODS Of 256 consecutive patients undergoing end-to-side epididymovasostomy 49 had primary epididymal obstruction unrelated to prior vasectomy. Patients were excluded from study if they had a history of vasectomy, microsurgical reconstruction or ejaculatory duct obstruction. RESULTS Followup was available in 43 of the 49 patients (88%). Patency rates were 87% in the bilateral epididymovasostomy group, 69% in the unilateral group and 81% overall. Pregnancy rates were 43% in the bilateral and 23% in the unilateral group. While higher patency rates were observed for proximal anastomoses, higher pregnancy rates were observed for distal anastomoses. Intraoperative epididymal fluid quality correlated with patency, that is motile sperm in the epididymal aspirate correlated with postoperative patency (p <0.05). There was no correlation between fluid quality and pregnancy rates. Postoperative semen analyses demonstrated higher sperm density and higher motility in the pregnant versus nonpregnant groups. CONCLUSIONS Epididymovasostomy may be performed in patients with obstructive azoospermia unrelated to vasectomy with high patency and good pregnancy rates. Intraoperative epididymal fluid quality can be predictive of patency. There was a trend towards higher pregnancy rates for distal anastomosis. There were no pregnancies when anastomosis was at the caput epididymis on both sides.

TESTIS BIOPSY FINDINGS IN THE SPINAL CORD INJURED PATIENT

PURPOSE Azoospermia after electroejaculation in spinal cord injured men may be due to testicular failure or obstruction. These men can initiate pregnancy with assisted reproductive techniques, such as intracytoplasmic sperm injection, but only if sperm are present in the testis biopsy. We analyzed the histopathology of testis biopsies from spinal cord injured men and assessed whether patient factors were predictive of testis biopsy pathology. MATERIALS AND METHODS A total of 50 paraplegic men undergoing testis biopsy were divided into 2 groups based on normal or abnormal testis histopathology. Patient age, post-injury years, level of lesion, hormonal status and semen analysis results were compared. RESULTS Spermatogenesis was normal in 28 of the 50 patients. Hypospermatogenesis was exhibited in 15, maturation arrest at the spermatid stage in 6 and maturation arrest at the spermatocyte stage in 1 of the 22 abnormal cases. Nevertheless, mature sperm were identified in 43 of 50 biopsies (normal spermatogenesis and hypospermatogenesis). Men with normal spermatogenesis had better forward progression of sperm and a higher testosterone-to-luteinizing hormone ratio. Otherwise, there was no statistically significant correlation between study variables and testis biopsy results. No factors were predictive of testis biopsy histopathology. CONCLUSIONS The documentation of mature sperm in 43 of 50 biopsies from spinal cord injured patients suggests that a high rate of sperm retrieval is possible using testicular sperm extraction if sperm cannot be retrieved from the ejaculate. With intracytoplasmic sperm injection techniques the majority of spinal cord injured men retain fertility potential, even if azoospermic following electroejaculation.

Salpingo-oophorectomy at the Time of Benign Hysterectomy: A Systematic Review.

OBJECTIVE: To compare the long-term risks associated with salpingo-oophorectomy with ovarian conservation at the time of benign hysterectomy. DATA SOURCES: MEDLINE, ClinicalTrials.gov, and the Cochrane Central Register of Controlled Trials were searched from inception to January 30, 2015. We included prospective and retrospective comparative studies of women with benign hysterectomy who had either bilateral salpingo-oophorectomy (BSO) or conservation of one or both ovaries. METHODS OF STUDY SELECTION: Reviewers double-screened 5,568 citations and extracted eligible studies into customized forms. Twenty-six comparative studies met inclusion criteria. Studies were assessed for results, quality, and strength of evidence. TABULATION, INTEGRATION, AND RESULTS: Studies were extracted for participant, intervention, comparator, and outcomes data. When compared with hysterectomy with BSO, prevalence of reoperation and ovarian cancer was higher in women with ovarian conservation (ovarian cancer risk of 0.14–0.7% compared with 0.02–0.04% among those with BSO). Hysterectomy with BSO was associated with a lower incidence of breast and total cancer, but no difference in the incidence of cancer mortality was found when compared with ovarian conservation. All-cause mortality was higher in women younger than age 45 years at the time of BSO who were not treated with estrogen replacement therapy (hazard ratio [HR] 1.41, 95% confidence interval [CI] 1.04–1.92). Coronary heart disease (HR 1.26, 95% CI 1.04–1.54) and cardiovascular death were higher among women with BSO (HR 1.84, 95% CI 1.27–2.68), especially women younger than 45 years who were not treated with estrogen. Finally, there was an increase in the prevalence of dementia and Parkinson disease among women with BSO compared with conservation, especially in women younger than age 50 years. Clinical practice guidelines were devised based on these results. CONCLUSION: Bilateral salpingo-oophorectomy offers the advantage of effectively eliminating the risk of ovarian cancer and reoperation but can be detrimental to other aspects of health, especially among women younger than age 45 years.

Intraoperative fetal heart rate monitoring during nonobstetric surgery in pregnancy: a practice survey.

Objective: To assess practice patterns concerning intraoperative fetal heart rate monitoring during nonobstetric surgery in pregnancy among members of the Association of Professors of Gynecology and Obstetrics (APGO). Study Design: A 16-question survey regarding intraoperative fetal heart rate monitoring during nonobstetric surgery was delivered to the 1300 APGO members via email. Descriptive statistics were used to determine the reasons for fetal monitoring during nonobstetric surgery in pregnancy. Results: Concerning intraoperative monitoring during nonobstetric surgery, 98% of respondents recorded the fetal heart rate pre-and post-surgery, and 43% of respondents reported they usually monitor intraoperatively. Of the 1151 physicians surveyed, 16% completed the survey. Conclusion: The majority of APGO members surveyed do not employ intraoperative fetal heart rate monitoring during nonobstetric surgery in pregnancy.

Sling surgery for stress urinary incontinence in women: A systematic review and meta-analysis

Traditional treatment options in women with stress urinary incontinence (SUI) include Burch urethropexy or pubovaginal slings. These procedures have become much less popular and less frequently performed with the development and increased use of synthetic midurethral slings (MUSs). These trends in practice have not been associated with dramatic improvements in outcomes, however, and up to a third of women require repeat surgery. Therefore, it is important to understand the comparative effectiveness of competing surgical repair procedures. The primary aim of this systematic review and meta-analysis was to compare objective and subjective cure rates in adult women with SUI treated with different surgical procedures. A systematic review was performed using the MEDLINE and Cochrane Central Register for Controlled Trials databases to obtain English-language comparative studies, cohort studies, and systematic reviews published from 1990 through April 2013 comparing a sling procedure for SUI to another sling or to Burch urethropexy. For evaluation of outcomes, only peer-reviewed randomized controlled trials with at least 12 months of follow-up were included. The minimum requirement for meta-analysis was at least 3 randomized controlled trials that compared the same surgeries for the same outcome and provided adequate efficacy and adverse event data. A random-effects model meta-analysis was used to estimate pooled odds ratios (ORs). Comparison ofMUS vs Burch urethropexy (open or laparoscopic):Meta-analysis of objective cure showed no significant difference between these 2 procedures (OR, 1.18; 95% confidence interval [CI], 0.73–1.89). There was also no difference between these 2 surgeries for outcomes of subjective cure, quality of life, or sexual function. Either an MUS or Burch procedure can be used. The choice should be based on potential adverse events and planned concomitant surgeries. Comparison of pubovaginal sling vs Burch urethropexy: Because the evidence favored pubovaginal slings for both subjective and objective cure, the authors recommended use of pubovaginal slings to maximize cure outcomes. Comparison of pubovaginal slings vs MUS: Meta-analysis of subjective cure favored MUS (OR, 0.40; 95% CI, 0.18–0.85). A meta-analysis for objective cure could not be performed because of inadequate data. Based on the subjective evidence for better cure, the authors recommended MUS. www.obgynsurvey.com | 586 Copyright
