RESUMO
PURPOSE: Active surveillance is an important alternative to definitive therapy for men with low risk prostate cancer. However, the impact of active surveillance on health related quality of life compared to that in men without cancer remains unknown. In this study we evaluated health related quality of life outcomes in men on active surveillance compared to men followed after negative prostate needle biopsy. MATERIALS AND METHODS: A prospective study was conducted on men who were enrolled into the Center for Prostate Disease Research Multicenter National Database and underwent prostate needle biopsy for suspicion of prostate cancer between 2007 and 2014. Health related quality of life was assessed at biopsy (baseline) and annually for up to 3 years using SF-36 and EPIC questionnaires. Health related quality of life scores were modeled using generalized estimating equations, adjusting for baseline health related quality of life, and demographic and clinical characteristics. RESULTS: Of the 1,204 men who met the initial eligibility criteria 420 had a negative prostate needle biopsy (noncancer comparison group). Among the 411 men diagnosed with low risk prostate cancer 89 were on active surveillance. Longitudinal analysis revealed that for most health related quality of life subscales there were no significant differences between the groups in adjusted health related quality of life score trends over time. CONCLUSIONS: In this study most health related quality of life outcomes in patients with low risk prostate cancer on active surveillance did not differ significantly from those of men without prostate cancer. A comparison group of men with a similar risk of prostate cancer detection is critical to clarify the psychological and physical impact of active surveillance.

BACKGROUND: For patients with low-risk prostate cancer (PCa), active surveillance (AS) may produce oncologic outcomes comparable to those achieved with radical prostatectomy (RP). Health-related quality-of-life (HRQoL) outcomes are important to consider, yet few studies have examined HRQoL among patients with PCa who were managed with AS. In this study, the authors compared longitudinal HRQoL in a prospective, racially diverse, and contemporary cohort of patients who underwent RP or AS for low-risk PCa. METHODS: Beginning in 2007, HRQoL data from validated questionnaires (the Expanded Prostate Cancer Index Composite and the 36-item RAND Medical Outcomes Study short-form survey) were collected by the Center for Prostate Disease Research in a multicenter national database. Patients aged ≤75 years who were diagnosed with low-risk PCa and elected RP or AS for initial disease management were followed for 3 years. Mean scores were estimated using generalized estimating equations adjusting for baseline HRQoL, demographic characteristics, and clinical patient characteristics. RESULTS: Of the patients with low-risk PCa, 228 underwent RP, and 77 underwent AS. Multivariable analysis revealed that patients in the RP group had significantly worse sexual function, sexual bother, and urinary function at all time points compared with patients in the AS group. Differences in mental health between groups were below the threshold for clinical significance at 1 year. CONCLUSIONS: In this study, no differences in mental health outcomes were observed, but urinary and sexual HRQoL were worse for patients who underwent RP compared with those who underwent AS for up to 3 years. These data offer support for the management of low-risk PCa with AS as a means for postponing the morbidity associated with RP without concomitant declines in mental health.

PURPOSE: Most prostate cancer active surveillance protocols recommend a confirmatory biopsy within 3 to 6 months of diagnosis. Transperineal template guided biopsy is an approach to improve the detection of high grade prostate cancer. However, to our knowledge the optimal technique is unknown. We evaluated the relative performance of 2 transperineal template guided biopsy approaches. MATERIALS AND METHODS: Institutional review board approved prospective databases at Virginia Mason and University of Michigan were used. Men eligible for active surveillance based on initial 12-core biopsy demonstrating NCCN® guideline low risk prostate cancer were included in study. All men underwent confirmatory transperineal template guided biopsy between 2005 and 2014, and within 6 months of diagnosis. The biopsy technique was based on a 24-core template with 12 anterior and 12 posterior cores or a template based on gland volume with an average of 1 core per cc. Outcome comparisons were made by the chi-square and Fisher exact tests, the Welch t-test and linear regression. RESULTS: Of the 135 men 46 underwent 24-core biopsy and 89 underwent volume based biopsy (median 62 cores). No statistically significant difference was noted in the prevalence of upgrading (35% vs 29%, p = 0.64) or complications (9% vs 16%, p = 0.38) between the 24-core and volume based groups. The difference in the probability of upgrading by volume based biopsy adjusted for age, prostate specific antigen, prostate volume, clinical stage and number of prior biopsies was -4% (95% CI -24 to 14%, p = 0.63). CONCLUSIONS: A significant difference was not detected in upgrading or morbidity between a 24-core template and a more exhaustive volume based template. A less invasive 24-core transperineal template guided biopsy strategy may suffice to accurately identify men who are appropriate for active surveillance.

INTRODUCTION: The purpose of this study is to determine if administration of total parenteral nutrition (TPN) immediately following radical cystectomy and urinary diversion provides significant recovery benefit when compared to patients who did not receive TPN. METHODS: Retrospective chart review was performed on patients who underwent open radical cystectomy and urinary diversion from February 2002 to June 2010. Patients were divided into 2 cohorts-those who received immediate postoperative TPN and those who did not. Preoperative demographics, length of hospital stay, time until tolerating a regular diet and early postoperative complications of the 2 groups were extracted and compared. RESULTS: One hundred seventy-four patients (104 receiving TPN, 70 without TPN) were available for analysis. No significant difference in preoperative characteristics, length of hospital stay, estimated blood loss, or time until tolerating a general diet between the 2 groups was noted. With regard to complications, the incidence of bacteremia was significantly higher in the TPN vs non-TPN cohort (9% vs 1%, P < 0.05). CONCLUSION: Immediate administration of TPN following radical cystectomy and urinary diversion does not provide a significant postoperative benefit and may lead to an increased risk of bacteremia.

PURPOSE: Obesity is recognized as a potential contributor to male factor infertility. There are no studies to date to our knowledge that have examined the success of varicocelectomy in obese men. We determined if body mass index significantly affects the outcome of varicocelectomy. MATERIALS AND METHODS: Retrospective chart review was performed for all patients who underwent varicocelectomy from September 2003 to December 2009. Patients were placed into 3 groups based on body mass index, and categorized as normal weight (group 1-38 patients, body mass index 18.5 to 24.9), overweight (group 2-59 patients, body mass index 25 to 29.9) or obese (group 3-46 patients, body mass index 30 or greater). Significant improvement was defined as a greater than 50% increase in the total motile per ejaculate parameter on postoperative semen analysis. RESULTS: A total of 143 patients were available for analysis. There were no significant differences among patients in the 3 groups except for body mass index. Significant improvement in total motile/ejaculate on semen analyses was 71.1% (group 1), 61.0% (group 2) and 58.7% (group 3). Pregnancy rates were 43.8% (group 1), 43.5% (group 2) and 46.3% (group 3). There were no significant differences in improvement in total motile per ejaculate (p = 0.21, p = 0.17) or pregnancy rate (p = 0.60, p = 0.51) between the normal body mass index group, and the overweight and obese groups. CONCLUSIONS: Varicocelectomy for men with clinically palpable varicoceles has a significant chance of improving semen parameters and pregnancy rates regardless of preoperative body mass index. The outcomes of varicocelectomy in overweight and obese patients were similar to those of normal weight men. Therefore, varicocelectomy can be performed effectively and safely in overweight and obese men.

AIM: The objective of this study was to investigate the prognostic importance of right ventricular dysfunction (RVD) and tricuspid regurgitation (TR) in patients with moderate-severe functional mitral regurgitation (FMR) receiving MitraClip procedure. RVD and TR grade are associated with cardiovascular mortality in the general population and other cardiovascular diseases. However, there are limited data from observational studies on the prognostic significance of RVD and TR in FMR receiving MitraClip procedure. METHODS AND RESULTS: A systemic review and meta-analysis were performed using MEDLINE, Scopus, and Embase to assess the prognostic value of RVD and TR grade for mortality in patients with functional mitral regurgitation (FMR) receiving MitraClip procedure. Hazard ratios were extracted from multivariate models reporting on the association of RVD and TR with mortality and described as pooled estimates with 95% confidence intervals. A total of eight non-randomized studies met the inclusion criteria with seven studies having at least 12 months follow-up with a mean follow-up of 20.9 months. Among the aforementioned studies, a total of 1112 patients (71.5% being male) were eligible for being included in our meta-analysis with an overall mortality rate of 28.4% (n = 316). Of the enrolled patients, RVD was present in 46.1% and moderate-severe TR in 29.2%. RVD was significantly associated with mortality compared to normal RV function (HR, 1.79, 95% CI, 1.39-2.31, P < 0.001, I2 = 0). Patients with moderate-severe TR showed increased risk of mortality compared with those in the none-mild TR group (HR, 1.61. 95% CI, 1.11-2.33, P = 0.01, I2 = 14). CONCLUSIONS: This meta-analysis demonstrates the prognostic importance of RVD and TR grade in predicting all-cause mortality in patients with significant FMR. RV function and TR parameters may therefore be useful in the risk stratification of patients with significant FMR undergoing MitraClip procedure.

INTRODUCTION AND HYPOTHESIS: A subset of neurologically normal females void by efficient Valsalva, not detrusor contraction. We determined the incidence of urinary retention following midurethral sling (MUS) placement in women that void by detrusor contraction versus Valsalva. METHODS: Review of patients undergoing MUS insertion between 2002 and 2009 for urodynamic stress incontinence was performed. Women with concomitant pelvic surgery, previous incontinence surgery, or preoperative incomplete bladder emptying were excluded. Patients were divided into two cohorts based on preoperative urodynamic findings--those that voided with a detrusor contraction >10 cm of water and those that voided by Valsalva. RESULTS: One hundred seven patients were available for analysis. The postoperative urinary retention rate was 22% and 5% in the Valsalva and non-Valsalva groups, respectively (p < 0.05). Mean retention duration was 3 weeks for each cohort (range 1-6). CONCLUSIONS: Women voiding by Valsalva are at increased risk of urinary retention following MUS placement.

BACKGROUND: Establishing normal values and associated variations of three-dimensional speckle-tracking echocardiography- (3DSTE-) derived left ventricular (LV) strain is necessary for accurate interpretation and comparison of measurements. We aimed to perform a meta-analysis of normal ranges of LV global longitudinal strain (GLS), global circumferential strain (GCS), global radial strain (GRS), and global area strain (GAS) measurements derived by 3DSTE and to identify confounding factors that may contribute to variance in reported measures. METHODS: The authors searched four databases, PubMed, Scopus, Embase, and Cochrane Library, through January 2019 using the key terms "left ventricular/left ventricle/left ventricles", "strain/deformation/speckle tracking", and "three dimensional/three-dimensional/three-dimension/three dimension/3D". Studies were included if the articles reported LV strain using 3DSTE in healthy normal subjects, either in the control group or comprising the entire study cohort. The weighted mean was estimated by using the random effects model with a 95% CI. Heterogeneity across studies was assessed using the I2 test. Effects of demographic (age), clinical, and vendor variables were assessed in a metaregression. The National Institutes of Health tools were used to assess the quality of included articles. Publication bias was examined by Begg's funnel plot and Egger's regression test. RESULTS: The search yielded 895 articles. After abstract and full-text screening we included 33 data sets with 2,346 patients for meta-analysis. The reported normal mean values of GLS among the studies varied from -15.80% to -23.40% (mean, -19.05%; 95% CI, -18.18% to -19.93%; I2 = 99.0%), GCS varied from -15.50% to -39.50% (mean, -22.42%; 95% CI, -20.96% to -23.89%, I2 = 99.7%), GRS varied from 19.81% to 86.61% (mean, 47.48%; 95% CI, 41.50%-53.46%; I2 = 99.8%), and GAS varied from -27.40% to -50.80% (mean, -35.03%; 95% CI, -33.19% to -36.87%; I2 = 99.3%). Software for strain analysis was consistently associated with variations in normal strain values (GLS: P = .016; GCS: P < .001; GRS: P < .001; GAS: P < .001). CONCLUSIONS: Variations in the normal ranges across studies were significantly associated with the software used for strain analysis, emphasizing that this factor must be considered in the interpretation of strain data.

BACKGROUND: The current study was conducted to determine the feasibility of cytologically clearing the bladder of tumor cells after transurethral resection of bladder tumor (TURBT) and aggressive serial bladder washing. METHODS: A prospective pilot sample of 20 patients with known bladder masses was enrolled before undergoing TURBT. Preoperative cytology and 4 postoperative cytology specimens were assessed for malignant cells between serial bladder washes. Surgeons assessed tumor grade visually at the time of TURBT. RESULTS: Surgeons were able to differentiate high-grade disease with limited accuracy (75% sensitivity, 92% specificity, 85% negative predictive value, and 86% positive predictive value). For patients with low-grade disease (12 patients), cytology was atypical in 25% of patients immediately before TURBT and was negative after serial washings in all patients. In patients with high-grade disease (8 patients), approximately 75% had cytology consistent with high-grade urothelial carcinoma immediately before TURBT and only 1 patient was cleared cytologically after serial bladder washings. CONCLUSIONS: In patients with high-grade disease, serial bladder washing after TURBT does not appear to clear malignant cells as detected by cytology. This theoretical oncologic risk should be weighed when considering concomitant upper tract procedures such as retrograde pyelography. Future work is needed to quantify risk.

We report an interesting case of Buerger's disease that manifested at the glans penis in a 56 year-old former smoker. Penile involvement in Buerger's disease is rare. Our patient had no prior extremity or digit amputations in his 4-year history of Buerger's disease. However, our patient did suffer from recurrent penile ulcers over an 8-week timeframe that ultimately progressed to a gangrenous, unsalvageable glans penis. He underwent a partial penectomy and urethral reconstruction with excellent post-operative results.
RESUMO
A 50-year-old man with benign prostatic hyperplasia and urinary retention had a very large diverticulum on the posterior wall of the bladder. The patient was managed with transurethral resection of the prostate and endoscopic fulguration of the bladder diverticulum mucosa using the Orandi technique. There was near-complete resolution of the bladder diverticulum following endoscopic management, obviating the need for bladder diverticulectomy. The patient now empties his bladder, with a postvoid residual < 50 mL and the absence of urinary tract infection after 6-month follow-up. We report the successful treatment of a large bladder diverticulum with endoscopic fulguration to near-complete resolution. This minimally invasive technique is a useful alternative in patients unfit for a more extensive surgical approach.
RESUMO
INTRODUCTION: The impact of transrectal ultrasound guided prostate needle biopsy on erectile dysfunction remains uncertain. We examined whether transrectal ultrasound guided prostate needle biopsy contributes to the development or worsening of erectile dysfunction as assessed by IIEF-5 scores in patients who underwent multiple prostate needle biopsies. METHODS: The study population consisted of 826 men who underwent transrectal ultrasound guided 10 to 12-core prostate needle biopsy for suspicion or surveillance of prostate cancer. Men were evaluated for erectile dysfunction using the IIEF-5 questionnaire. Erectile dysfunction was modeled as a categorical variable, defined as any (0 to 20), mild (16 to 20), mild to moderate (11 to 15), moderate (6 to 10) or severe (0 to 5). The impact of multiple prostate needle biopsies was also evaluated. RESULTS: Of 826 men who underwent prostate needle biopsy 240 (29%) had undergone 1 or more and 168 (20%) had undergone 2 or more biopsies. Mean patient age was 63 years and mean IIEF-5 score was 16. On univariate analysis age (OR 1.11, 95% CI 1.09-1.14, p <0.001), and 1 (OR 1.79, 95% CI 1.06-3.03, p=0.03) or 2 (OR 1.80, 95% CI 1.02-3.17, p=0.04) prior prostate needle biopsies were associated with erectile dysfunction. On multivariate analysis age alone was predictive of severe erectile dysfunction (OR 1.09, 95% CI 1.05-1.12, p=0.002). A repeat prostate needle biopsy within 12 months was associated with worse erectile dysfunction (OR 1.55, 95% CI 1.08-2.93, p=0.02). When long-term erectile function was evaluated, prostate needle biopsy was not significant after adjustment for covariates. CONCLUSIONS: In the short term prostate needle biopsy may be important in predicting transient (less than 1 year) erectile dysfunction. However, in the long term prostate needle biopsy does not predict erectile dysfunction in aging men.
RESUMO
OBJECTIVE: To report the long-term oncologic outcomes of laparoscopic cryoablation for clinical stage T1 renal masses at the Medical College of Wisconsin. MATERIALS AND METHODS: A retrospective chart review was performed evaluating patients who underwent laparoscopic cryoablation for renal masses at the Medical College of Wisconsin between February 2000 and October 2009. RESULTS: A total of 171 renal masses in 144 patients were treated by laparoscopic cryoablation during the study period. After excluding patients with <5 years follow-up and those with >clinical stage I disease, 112 renal masses treated in 92 patients remained for analysis. Mean patient age was 59.6 years (standard deviation [SD], 12.5 years). Mean lesion size was 2.3 cm (SD, 0.94 cm). Mean age adjusted Charlson comorbidity index was 4.55 (SD, 1.69). Mean follow-up was 97.9 months (SD, 24.8 months). Overall survival among all patients was 80.9%. Lesions were biopsy proven to be malignant in 70 patients (76.3%). Of those with biopsy-proven malignancy, there were 6 recurrences, 14 non-cancer-related deaths, and 1 cancer-related death, leading to an overall survival of 77.6%, progression-free survival of 91.0%, and cancer-specific survival of 98.5%. CONCLUSION: We report the largest published series of laparoscopic renal cryoablation with the longest follow-up. Our series indicates that laparoscopic cryoablation is both an efficacious treatment for clinical stage T1 renal masses and provides excellent long-term oncologic outcomes.

INTRODUCTION: Clinical stage I seminoma can be managed with surveillance, chemotherapy or radiotherapy with similar survival rates. However, costs and side effects vary among these treatment modalities. We created a model to estimate the direct and indirect costs during the first 5 years of treatment for the 3 treatment strategies. METHODS: Markov model based analyses were conducted to compare the costs of the 3 management strategies during the first 5 years. In this model clinicians and patients were assumed to be 100% compliant with the 2012 NCCN Guidelines® for testicular cancer. Model parameters were collected from the Washington State CHARS (Comprehensive Hospital Abstract Reporting System), published literature and Medicare reimbursement amounts. A 5% annual health inflation rate was assumed. RESULTS: The model predicts an initial cost premium for carboplatin (1 cycle-$9,199.49; 2 cycles-$10,613.85) and radiotherapy ($9,532.80) compared with surveillance ($9,065.31). Radiotherapy (145.8 hours) and surveillance (123.0 hours) require more patient time than carboplatin (1 cycle-93.2 hours, 2 cycles-106.3 hours). When the direct and indirect costs are considered, the least expensive management strategy is surveillance. CONCLUSIONS: Surveillance is the most cost-effective management strategy for clinical stage I seminoma during the first 5 years of treatment. Although not evaluated in this analysis, costs of late side effects associated with radiotherapy and chemotherapy should be considered. Due to potentially minimal late side effects and superior cost-effectiveness, surveillance represents a safe, cost-effective and time effective option for the management of stage I seminoma.
RESUMO
INTRODUCTION: Robotic-assisted radical cystectomy (RARC) is an emerging minimally invasive alternative for the treatment of invasive bladder cancer. The V-loc (Covidien, Mansfield, MA) suture is a unidirectional barbed suture that provides even distribution of tension. We determined the rate of urinary leak at the urethro-intestinal anastomosis following orthotopic neobladder construction performed with V-loc suture. METHODS: We retrospectively reviewed charts on all patients that underwent RARC with orthotopic neobladder urinary diversion performed with a V-loc suture from February 2010 to February 2012. The urethro-intestinal anastomosis was evaluated for urinary leak by cystogram at 3 to 4 weeks, postoperatively. RESULTS: In total, 11 patients were available for analysis. The mean patient age was 57.2 years (range: 47-71). The average clinical follow-up was 8 months (range: 4-15). On surgical pathology, 8 (73%) patients had pT2 or less disease, 3 (27%) had pT3/T4 disease, and 1 (9%) had N+ disease. The mean intraoperative blood loss was 315 mL (range: 150-600) and the average operative time was 496 minutes (range: 485-519). No patient (0%) demonstrated a urinary leak at the urethro-intestinal anastomosis on postoperative cystogram. Eight patients (73%) were continent by 4 months, postoperatively. CONCLUSIONS: Orthotopic neobladder urethro-intestinal anastomosis can be performed effectively and safely with V-loc suture with an acceptably low urinary leak rate.
