Relating economic conditions to vasectomy and vasectomy reversal frequencies: a multi-institutional study.

PURPOSE: It was theorized that the use of permanent contraceptive methods may vary with economic conditions. We evaluated the relationship between vasectomy/vasectomy reversal frequencies at several large referral centers and national economic indicators during 2 recessions spanning 2001 to 2011. MATERIALS AND METHODS: We performed an institutional review board approved, retrospective chart review to identify the number of vasectomies/vasectomy reversals per month at several large referral centers from January 2001 to July 2011. The rates of these procedures were pooled, correlated with national economic data and analyzed in a multivariate linear regression model. RESULTS: A total of 4,599 vasectomies and 1,549 vasectomy reversals were performed at our institutions during the study period. The number of vasectomies per month positively correlated with the unemployment rate (r=0.556, p<0.001) and personal income per capita (r=0.276, p=0.002). The number of reversals per month negatively correlated with the unemployment rate (r=-0.399, p<0.001) and personal income per capita (r=-0.305, p<0.001). Neither vasectomy nor vasectomy reversal frequency significantly correlated with the inflation rate or the S&P 500®. Regression models confirmed that the unemployment rate explained more of the variance in vasectomy/vasectomy reversal frequencies than other indicators. CONCLUSIONS: We noted a correlation between the number of vasectomies/vasectomy reversals performed at our institutions and national economic indicators. The strongest association was with the unemployment rate. This points to the importance of financial pressure on family planning decisions.

National trends in the treatment of penile prosthesis infections by explantation alone vs. immediate salvage and reimplantation.

INTRODUCTION: A penile prosthesis infection (PPI) is either treated with explantation of the prosthesis with a possible delayed reimplantation or a salvage procedure with an immediate reimplantation of the prosthesis. AIM: We used a large, all-payer national database to investigate the use of the salvage procedure in the setting of PPI. METHODS: The study used years 2000-2009 of the Nationwide Inpatient Sample to identify PPIs treated with immediate salvage or explantation alone. Admissions were then stratified by various parameters to compare differences in the salvage rates. MAIN OUTCOME MEASURES: Salvage Rate of Penile Prosthesis infection. RESULTS: A total of 1,557 patients were treated with an explantation only (82.7%) or salvage (17.3%) for PPI, a proportion that remained stable over the study period. The patients treated with salvage were younger (60.4 vs. 65.1 years), more likely to be discharged home (87.3% vs. 61.9%), and were less likely to have a severe presentation (7.2% vs. 31.6%) than those who were explanted only (P < 0.001). These factors were confirmed on multivariate regression analysis. The regression also revealed that treatment at rural hospitals had lower odds of salvage than treatment at urban teaching hospitals. Race, comorbid diabetes, and insurance status did not independently affect the salvage rate. There was no significant difference in total hospital charges between groups. CONCLUSIONS: Salvage rates have remained low over the past decade. Our study elucidated several factors decreasing the chances of salvage after PPI including age, severity of presentation, and hospital setting.

Testosterone supplementation does not worsen lower urinary tract symptoms.

PURPOSE: Testosterone replacement therapy is commonly used to treat men with hypogonadism. However, there has been caution in using testosterone replacement therapy in men with moderate to severe lower urinary tract symptoms for fear of worsening the symptoms. In this study we examine the effect of testosterone replacement therapy on lower urinary tract symptoms in hypogonadal men. MATERIALS AND METHODS: We retrospectively reviewed our outpatient database and identified patients with a diagnosis of hypogonadism who received testosterone replacement therapy from 2002 to 2012. Lower urinary tract symptoms were assessed using the AUASI (American Urological Association symptom index) before and after testosterone replacement therapy. Testosterone and prostate specific antigen were also continuously measured, and all patients were closely monitored for side effects of testosterone replacement therapy. Patients who had progression of lower urinary tract symptoms to the point of requiring surgery were included in the study. RESULTS: We identified 120 hypogonadal men who received testosterone replacement therapy, the majority of whom had topical therapy or a combination of topical and pellet based therapy (57.5% and 20.8%, respectively). Mean baseline AUASI (±SD) was 10.8 (±7.8) and mean duration of testosterone replacement therapy was 692 days (±773). Mean change in AUASI was -1.07 (±6.06). Mean baseline prostate specific antigen was 1.6 ng/dl (±1.9) and mean change in prostate specific antigen was 0.44 (±2.2). Of the patients 8.1% had a baseline prostate specific antigen greater than 4.0 ng/dl, and these patients had greater improvement in AUASI than those with a baseline prostate specific antigen less than 4.0 ng/dl (-1.9 vs -1.0, p not significant). Overall 45.8% of patients had a less than 3-point change in AUASI in either direction. Of the 120 patients 38 (31.7%) had improvement in AUASI 3 or more points while 27 (22.5%) had worsening of AUASI 3 or more points. Patients with an improved AUASI had a mean prostate specific antigen change of 0.3 (±3.4), while those who had worsening of AUASI had a mean prostate specific antigen change of 0.7 (±2.2) (p not significant). Approximately 9 of 120 (7.5%) of these men initiated new medications for lower urinary tract symptoms during the course of the study. There was no significant change in AUASI compared to patients without any use of lower urinary tract symptoms medications. In addition, 4 (3.3%) patients had progression of lower urinary tract symptoms and required transurethral resection of the prostate. CONCLUSIONS: We demonstrate that initiating testosterone replacement therapy in hypogonadal men involves a low risk of worsening lower urinary tract symptoms. In fact, many men experience symptom improvement while changes in prostate specific antigen appear minor. Future research should focus on larger patient population studies to further examine this relationship.

Prostate cancer diagnosis is associated with an increased risk of erectile dysfunction after prostate biopsy.

OBJECTIVE: To evaluate prospectively the characteristics, erectile function and lower urinary tract symptoms (LUTS) of men undergoing prostate needle biopsy (PNBx). PATIENTS AND METHODS: From 2008 to 2011, 134 men were prospectively administered the International Index of Erectile Function (IIEF), American Urological Association Symptom Index (AUA-SI), and quality-of-life (QoL) questionnaires before and after undergoing a single 12-core PNBx. Comparisons of IIEF and AUA-SI scores before and after PNBx, based upon baseline characteristics and prostate cancer (PCa) diagnosis, were performed. Univariable and multivariable logistic regression models were used to characterize predictors of change in IIEF scores. RESULTS: In the 85 men who fulfilled the inclusion criteria, there were no significant differences between the mean (sd) total pre-biopsy and the mean (sd) post-biopsy IIEF scores: 57.8 (12.9) vs 54.3 (17.2). Subgroup analysis showed that men who had biopsy-proven PCa had significantly greater changes in their post-biopsy IIEF scores compared with men without (-10.1 vs. 1.0; P < 0.001). After specific analyses of the IIEF domains in these groups we found significant decreases in every domain, including erectile function (P = 0.01). On multivariate analyses, only PCa diagnosis was associated with a significant change in IIEF (odds ratio 7.2; P = 0.003). There were no differences in AUA-SI or QoL scores in the overall population or in subgroups. CONCLUSIONS: Cancer diagnosis appears to have an adverse effect on the erectile function of men undergoing PNBx but no effect on LUTS. This study highlights a potential negative psychological confounder that may influence erectile function before the treatment of PCa. Additional prospective trials evaluating these relationships are warranted.

Vasectomy demographics and postvasectomy desire for future children: results from a contemporary national survey.

OBJECTIVE: To describe the longitudinal demographics and family planning attitudes of vasectomized men with the use of the National Survey for Family Growth (NSFG). DESIGN: Retrospective cohort analysis of the NSFG with the use of national projections and multivariable regressions. SETTING: In-home survey. PATIENT(S): The NSFG sampled 10,403 men aged 15-45 years from 2006 to 2010 regarding family planning attitudes. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Vasectomy and desire for children. RESULT(S): There were 3,646,339 (6.6%) vasectomized men aged 18-45 years in the U.S. On multivariable regression the following factors increased the odds of having a vasectomy: currently married (odds ratio [OR] 7.814), previously married (OR 5.865), and increased age (OR 1.122) and income (OR 1.003). The odds of having a vasectomy increased with number of children. The following factors decreased the odds of having a vasectomy: immigrant status (OR 0.186), African American (OR 0.226), Hispanic (OR 0.543), Catholic (OR 0.549), and other non-Protestant religion (OR 0.109). Surprisingly, an estimated 714,682 (19.6%) vasectomized men in the U.S. desire future children. Men practicing a religion (OR 8.575-15.843) were more likely than atheists to desire children after vasectomy. 71,886 (2.0%) vasectomized men reported having a vasectomy reversal. CONCLUSION(S): This study highlights the importance of preoperative counseling for permanency of vasectomy and reveals an opportunity to counsel couples about vasectomy versus tubal ligation.
