RESUMO
PURPOSE: To compare the clinical presentation, treatment receipt, and oncologic outcomes between human immunodeficiency virus-seropositive (HIV+) and seronegative (HIV-) men with prostate cancer (CaP) matched by age, clinical stage, and race. MATERIALS AND METHODS: A retrospective review of 3,135 men treated for CaP from 2000 to 2016 was performed. HIV+ patients (Nâ¯=â¯46) were matched 1:2 to 3 to HIV- men (Nâ¯=â¯137) by age, race, and clinical stage. Clinicopathologic features and primary treatment received were compared between cohorts. Associations between HIV status and progression-free, cancer-specific, and overall survival were compared by HIV status using the Kaplan-Meier method and Cox proportional hazards analysis. RESULTS: After matching, men with and without HIV were similar with respect initial prostate-specific antigen, Gleason Sum, and Eastern Cooperative Oncology Group (ECOG) performance status. Among HIV+ men, 67.4% had a history of acquired immune deficiency syndrome, and 91.3% were on highly active antiretroviral therapy at CaP diagnosis. Among men with localized disease, HIV+ men were more likely to receive radiation (59.5% vs. 44.8%) or no therapy (13.5% vs. 4.3%) and less likely to receive surgery (16.2% vs. 30.2%), or to initiate active surveillance (10.8% vs. 16.4%; Pâ¯=â¯0.04 overall). There were no differences in rates of clinical progression, development of castration resistance, or CaP death by HIV status. However, HIV+ status was associated with inferior overall survival (hazard ratio 2.89, Pâ¯=â¯0.04). CONCLUSIONS: While most HIV+ patients had a history of acquired immune deficiency syndrome; HIV was well controlled in the majority of patients at the time of CaP diagnosis. While oncologic outcomes were similar between HIV+ and HIV- men, significant differences in treatment selection were observed. Further research is necessary to understand differences in treatment election by HIV status and to define optimal CaP treatment selection in men with HIV.

OBJECTIVE: To determine risk factors for continued smoking following a diagnosis of a genitourinary (GU) malignancy. Smoking is a well established risk factor in the development of cancers involving the GU tract. Unfortunately, a large percentage of patients continue to smoke or relapse after cancer diagnosis; by doing so, there is an increased risk of recurrence, poor survival rates, treatment complications, secondary primary cancers, and other chronic smoking related illnesses. MATERIALS AND METHODS: Two hundred and five patients who presented to a Urologic Oncology clinic at a single tertiary treatment center were given smoking cessation counseling and pharmacotherapy, as well as a questionnaire which was used to identify smoking status, demographics, and behavioral/psychosocial characteristics. Patients were followed for a minimum of 1 year with a median length of follow up for 13 months. RESULTS: 91% of patients enrolled in the study continued smoking at survey completion. After accounting for age, ethnicity, education and cigarettes consumed/day, 5 variables were independently associated with an increased risk of continued smoking: smoking 20 or more cigarettes per day, less than 2 prior quit attempts, anxiety and/or depression, fear of cancer recurrence, and home secondhand smoke exposure. CONCLUSION: The role of the urologist is imperative for encouraging smoking cessation. While every patient should receive adequate counseling regarding smoking at the time of a GU malignancy diagnosis, identifying patients with the risk factors noted in this study and augmenting smoking cessation efforts may result in stronger efforts to quit and prevention of long-term complications.

Since the original inflatable penile prosthesis in the 1970s, several enhancements to penile prosthesis implant design, implant surgical technique, and post-operative care have been developed to increase overall patient (and partner) satisfaction rates. We, in this communication, seek to discuss these advancements and the overall impact in combating erectile dysfunction. As we continue to pursue avenues of effective and definitive treatment modalities for erectile dysfunction refractory to medical therapy, rates of infection and mechanical failure will hopefully continue to decline in the perioperative setting.

We present a 55-year-old male, with good performance status who was diagnosed with a case of metastatic renal cell carcinoma following a pathologic femur fracture. Despite good performance status, multifocal metastases and poor-prognostic features portended a grim prognosis with predicted overall survival of less than nine months. On initial presentation, he was excluded from cytoreductive nephrectomy based on brain metastasis and interleukin-2 was not pursued as the primary tumor was to be left in situ. The patient was reconsidered for cytoreductive nephrectomy after sustained response to fifth line targeted therapies with shrinkage of tumor burden. The post-operative course was uneventful and the patient was discharged home on postoperative day one. Temsirolimus was resumed one week after surgery and the patient reported returning to his normal activities at the two week follow-up visit. We highlight important clinical features of metastatic renal cell carcinoma, the surgical considerations for cytoreductive nephrectomy and the detailed multidisciplinary care the patient received throughout this case report.
RESUMO
It remains evident in the literature that leiomyosarcomas of the bladder have continuously been regarded as highly aggressive tumors associated with a poor prognosis. Immediate surgical therapy by radical cystectomy with wide margins is warranted as an effective treatment modality and has been associated with longer survival rates. Herein, we present the case of a high-grade leiomyosarcoma primarily treated with anterior pelvic exenteration and urinary diversion.
RESUMO
Ureteroarterial fistulas (UAFs) are defined as an abnormal communication between one of the major arteries and the ureter. Urologists most frequently encounter iatrogenic fistulas occurring in patients with a history of pelvic extirpative surgery, chronic ureteral catheterization, and history of pelvic radiation. We present two cases of UAFs in patients with no history of prior radiation, who underwent open radical cystectomy and robot-assisted radical cystectomy with intracorporeal ileal conduit. Both patients developed postoperative ureteroileal anastomotic leaks that were managed with indwelling ureteral catheters. Furthermore, both patients were having left-sided UAF after presenting with nonlife threatening gross hematuria, which became brisk and pulsatile during ureteral stent exchange. Endovascular stenting was performed in both patients with resolution of hemorrhage and full recovery. In one patient, nephrostomy tubes were placed and ureteral catheters were removed; the second patient was managed with continued ureteral catheterization without further episodes of hematuria.
RESUMO
PURPOSE: Activities of daily living provide information about the functional status of an individual and can predict postoperative complications after general and oncological surgery. However, they have rarely been applied to urology. We evaluated whether deficits in activities of daily living could predict complications after percutaneous nephrolithotomy and how this compares with the Charlson comorbidity index and the ASA(®) (American Society of Anesthesiologists(®)) classification. MATERIALS AND METHODS: We retrospectively reviewed the records of all patients who underwent percutaneous nephrolithotomy between March 2013 and March 2014. Those with complete assessment of activities of daily living were included in analysis. Perioperative outcomes, complications and hospital length of stay were examined according to the degree of deficits in daily living activities. RESULTS: Overall 176 patients underwent a total of 192 percutaneous nephrolithotomies. Deficits in activities of daily living were seen in 16% of patients, including minor in 9% and major in 7%. Complications developed more frequently in those with vs without deficits in daily living activities (53% vs 31%, p = 0.029) and length of stay was longer (2.0 vs 4.5 days, p = 0.005). On multivariate logistic regression activities of daily living were an independent predictor of complications (OR 1.11, p = 0.01) but ASA classification and Charlson comorbidity index were not. CONCLUSIONS: Activities of daily living are easily evaluated prior to surgery. They independently predict complications following percutaneous nephrolithotomy better than the Charlson comorbidity index or the ASA classification. Preoperative assessment of daily living activities can help risk stratify patients and may inform treatment decisions.

INTRODUCTION: Multiple scoring systems have been proposed for prostate MRI reporting. We sought to review the clinical impact of the new Prostate Imaging Reporting and Data System v2 (PI-RADS) and compare those results to our proposed Simplified Qualitative System (SQS) score with respect to detection of prostate cancers and clinically significant prostate cancers. METHODS: All patients who underwent multiparametric prostate MRI (mpMRI) had their images interpreted using PI-RADS v1 and SQS score. PI-RADS v2 was calculated from prospectively collected data points. Patients with positive mpMRIs were then referred by their urologists for enrollment in an IRB-approved prospective phase III trial of mpMRI-Ultrasound (MR/TRUS) fusion biopsy of suspicious lesions. Standard 12-core biopsy was performed at the same setting. Clinical data were collected prospectively. RESULTS: 1060 patients were imaged using mpMRI at our institution during the study period. 341 participants were then referred to the trial. 312 participants underwent MR/TRUS fusion biopsy of 452 lesions and were included in the analysis. 202 participants had biopsy-proven cancer (64.7%) and 206 (45.6%) lesions were positive for cancer. Distribution of cancer detected at each score produced a Gaussian distribution for SQS while PI-RADS demonstrates a negatively skewed curve with 82.1% of cases being scored as a 4 or 5. Patient-level data demonstrated AUC of 0.702 (95% CI 0.65 to 0.73) for PI-RADS and 0.762 (95% CI 0.72 to 0.81) for SQS (p< 0.0001) with respect to the detection of prostate cancer. The analysis for clinically significant prostate cancer at a per lesion level resulted in an AUC of 0.725 (95% CI 0.69 to 0.76) and 0.829 (95% CI 0.79 to 0.87) for the PI-RADS and SQS score, respectively (p< 0.0001). CONCLUSIONS: mpMRI is a useful tool in the workup of patients at risk for prostate cancer, and serves as a platform to guide further evaluation with MR/TRUS fusion biopsy. SQS score provided a more normal distribution of scores and yielded a higher AUC than PI-RADS v2. However until our findings are validated, we recommend reporting of detailed sequence-specific findings. This will allow for prospectively collected data to be utilized in determining the impact of ongoing changes to these scoring systems as our understanding of mpMRI interpretation evolves.

BACKGROUND: The Prostate Cancer Prevention Trial risk calculator for high-grade (PCPTHG) prostate cancer (CaP) was developed to improve the detection of clinically significant CaP. In this study, the authors compared the performance of the PCPTHG against multiparametric magnetic resonance imaging (MP-MRI) in predicting men at risk of CaP. METHODS: Men with an abnormal prostate-specific antigen (PSA) level or digital rectal examination (DRE) and a suspicious lesion on a 3-Tesla MP-MRI were enrolled prospectively. Three radiologists reviewed and graded all lesions on a 5-point Likert scale. Biopsy of suspicious lesion(s) was performed using a proprietary MRI/transrectal ultrasound fusion-guided prostate biopsy system, after which 12-core biopsy was performed. A genitourinary pathologist reviewed all pathology slides. The performance of PCPTHG was compared with that of MP-MRI in predicting clinically significant CaP. RESULTS: Of 175 men who were eligible for analysis, 64.6% (113 of 175 men) were diagnosed with CaP, including 93 of 113 men (82.3%) who had clinically significant disease. Age, abnormal DRE, PSA, PSA density, prostate size, extraprostatic extension on MRI, apparent diffusion coefficient value, and MRI lesion size were identified as significant predictors of high-grade CaP (all P < .05). The area under the receiver operating characteristic curve of PCPTHG for predicting high-grade CaP was 0.676 (95% confidence interval [CI], 0.592-0.751). By using a risk cutoff of ≥15% for biopsy as, proposed previously for high-grade CaP, sensitivity was 96.4%, specificity was 7.6%, and the false-positive rate was 51.1%. In contrast, the area under the receiver operating characteristic curve of MP-MRI for high-grade CaP was 0.769 (95% CI, 0.703-0.834), and it was 0.812 (95% CI, 0.754-0.869) for clinically significant CaP. CONCLUSIONS: MP-MRI outperforms PCPTHG in predicting clinically significant CaP, and its application may help select patients who will benefit from CaP diagnosis and treatment.

PURPOSE: Given the limitations of prostate specific antigen and standard biopsies for detecting prostate cancer, we evaluated the cancer detection rate and external validity of a magnetic resonance imaging/transrectal ultrasound fusion guided prostate biopsy system used at the National Institutes of Health. MATERIALS AND METHODS: We performed a phase III trial of a magnetic resonance imaging/transrectal ultrasound fusion guided prostate biopsy system with participants enrolled between 2012 and 2013. A total of 153 men consented to the study and underwent 3 Tesla multiparametric magnetic resonance imaging with an endorectal coil for clinical suspicion of prostate cancer. Lesions were classified as low or moderate/high risk for prostate cancer. Magnetic resonance imaging/transrectal ultrasound fusion guided biopsy and standard 12-core prostate biopsy were performed and 105 men were eligible for analysis. RESULTS: Mean patient age was 65.8 years and mean prostate specific antigen was 9.5 ng/ml. The overall cancer detection rate was 62.9% (66 of 105 patients). The cancer detection rate in those with moderate/high risk on imaging was 72.3% (47 of 65) vs 47.5% (19 of 40) in those classified as low risk for prostate cancer (p<0.05). Mean tumor core length was 4.6 and 3.7 mm for fusion biopsy and standard 12-core biopsy, respectively (p<0.05). Magnetic resonance imaging/transrectal ultrasound fusion guided biopsy detected prostate cancer that was missed by standard 12-core biopsy in 14.3% of cases (15 of 105), of which 86.7% (13 of 15) were clinically significant. This biopsy upgraded 23.5% of cancers (4 of 17) deemed clinically insignificant on 12-core biopsy to clinically significant prostate cancer necessitating treatment. CONCLUSIONS: Magnetic resonance imaging/transrectal ultrasound fusion guided biopsy can improve prostate cancer detection. The results of this trial support the external validity of this platform and may be the next step in the evolution of prostate cancer management.

OBJECTIVE: To evaluate perspectives of urologists viewing live case demonstrations (LCD) and taped case demonstrations (TCD). METHOD: A 15-question anonymous survey was distributed to attendees of the live surgery session at the American Urological Association 2012 national meeting (Atlanta) and the second International Challenges in Endourology meeting (Paris). RESULTS: Of 1000 surveys distributed, 253 were returned completed (response rate 25%). Nearly half of respondents were in the academic practice setting and nearly 75% were beyond training. Just over 30% had performed a LCD previously. The perceived benefit of an LCD was greater than unedited and edited videos (chi-squared P = 0.014 and P < 0.001, respectively). Nearly no one selected 'not helpful' and a few selected 'minimally helpful' for any of the three forms of demonstration. Most respondents identified that opportunity to ask questions (61%) and having access to the full unedited version (72%), two features inherent to LCD, improved upon the educational benefit of edited videos. Most (78%) identified LCD as ethical. However, those that did not perceived lower educational benefit from LCD (P = 0.019). A slim majority (58%) would allow themselves or a family member to be a patient of a LCD and the vast majority (86%) plan to transfer knowledge gained at the LCD session into their practice. CONCLUSIONS: Urologists who attended these LCD sessions identified LCDs as beneficial and applicable to their practice. LCDs are preferred over videos. The large majority considers LCD ethical, although not as many would volunteer themselves for LCD. Further studies are necessary to determine if there is actual benefit from LCD over TCD to patient care.

On the basis of studies in experimental animals demonstrating that AdVEGF121, an E1(-)E3(-) serotype 5 adenovirus coding the 121 isoform of vascular endothelial growth factor (VEGF), could mediate the generation of new blood vessels and reverse coronary ischemia, a clinical study of direct myocardial administration of AdVEGF121 was initiated in patients with late-stage, diffuse coronary artery disease. This study provides long-term (median, 11.8 years) follow-up on these patients. From 1997 to 1999, AdVEGF121 was administered by direct myocardial injection to an area of reversible ischemia in 31 patients with severe coronary disease, either as an adjunct to conventional coronary artery bypass grafting (group A) or as minimally invasive sole (MIS) therapy, using a minithoracotomy (group B). There was no control group; the study participants served as the control subjects. The 5- and 10-year survival was 10 of 15 (67%) and 6 of 15 (40%) for the group A patients, and 11 of 16 (69%) and 5 of 16 (31%) for group B sole therapy patients, respectively. In comparison, maximal medical therapy in comparable groups in the literature have a 3- to 5-year survival rate of 52 to 59%. For the survivors, the angina score for group A was 3.4±0.5 at time 0 and 1.9±1.0 at last follow-up, and for group B it was 3.4±0.6 and 2.0±1.1, respectively. The incidences of malignancy and retinopathy were no greater than that expected for the age-matched general population. We conclude that adenovirus-mediated VEGF direct myocardial administration to patients with severe coronary artery disease is safe, and future larger trials are warranted to assess efficacy.

BACKGROUND: This study was performed to evaluate short-term clinical outcomes of laparoscopic intracorporeal ileocolic anastomosis following resection of the right colon. METHODS: This was a retrospective study of selected patients who underwent laparoscopic intracorporeal ileocolic anastomosis following resection of the right colon for tumors or Crohn's disease by a single surgeon from July 2002 through June 2012. Data were retrieved from an Institutional Review Board-approved database. Study end point was postoperative adverse events, including mortality, complications, reoperations, and readmissions at 30 days. Antiperistaltic side-to-side anastomoses were fashioned laparoscopically with a 60-mm-long stapler cartridge and enterocolotomy was hand-sewn intracorporeally in two layers. Values were expressed as medians (ranges) for continuous variables. RESULTS: There were 243 patients (143 females) aged 61 (range = 19-96) years, with body mass index of 29 (18-43) kg/m(2) and ASA 1:2:3:4 of 52:110:77:4; 30 % had previous abdominal surgery and 38 % had a preexisting comorbidity. There were 84 ileocolic resections with ileo ascending anastomosis and 159 right colectomies with ileotransverse anastomosis. Operating time was 135 (60-220) min. Estimated blood loss was 50 (10-600) ml. Specimen extraction site incision length was 4.1 (3-4.4) cm. Conversion rate was 3 % and there was no mortality at 30 days, 15 complications (6.2 %), and 8 reoperations (3.3 %). Readmission rate was 8.7 %. Length of stay was 4 (2-32) days. Pathology confirmed Crohn's disease in 84 patients, adenocarcinoma in 152, and other tumors in 7 patients. CONCLUSION: Laparoscopic intracorporeal ileocolic anastomosis following resection of the right colon resulted in a favorable outcome in selected patients with Crohn's disease or tumors of the right colon.
