Can Urinary Nerve Growth Factor Be a Biomarker for Overactive Bladder?

Diagnostic Update

Michael B ChancellorHann-Chorng KuoHsin-Tzu Liu

The clinical diagnosis of overactive bladder (OAB) greatly varies and is based on subjective symptoms. A more objective method to diagnose and assess therapeutic outcome in OAB patients, especially for health care providers not trained in urology, needs to be found. Evidence has shown that urinary proteins such as nerve growth factor (NGF) and prostaglandin E2 levels increase in patients with OAB, bladder outlet obstruction, and detrusor overactivity. Urinary NGF level increases physiologically in normal subjects at urge to void, but increases pathologically in OAB patients at a small bladder volume and with a sensation of urgency. Recent studies have shown that patients with OAB dry and OAB wet have significantly higher urinary NGF levels compared with control groups and patients with increased bladder sensation. Urinary NGF levels decrease after antimuscarinic therapy and further decrease after detrusor botulinum toxin injections in refractory OAB. Urinary NGF level could be a potential biomarker for diagnosis of OAB and assessment of the therapeutic effect of antimuscarinic therapy. The latest medical advances in this field are reviewed herein. [Rev Urol. 2010;12(2/3):e69-e77 doi: 10.3909/riu0432]

Histologic Changes in Prostate Cancer Detected Subsequent to the 2012 United States Preventive Services Task Force (USPSTF) Prostate Cancer Screening Recommendation

Ann E AndersonCarl A OlssonHugh J LaveryDeepak Kapoor

We report changes in the histopathology of prostate cancer diagnosed in a large urology group practice after the final United States Preventive Services Task Force (USPSTF) Grade D recommendation against prostate-specific antigen screening. All prostate biopsies performed from 2011 through 2015 in a large urology group practice were retrospectively reviewed; 2012 was excluded as a transition year. The changes in biopsy data in years following the USPSTF decision (2013-2015) were then compared with baseline (2011). A total of 10,944 biopsies were evaluated during the study period. Positive biopsy rates rose from 39.1% at baseline to 45.2% in 2015 (P < 0.01) with a marked shift toward more aggressive cancer throughout the study period. The absolute number of patients presenting with Gleason Grade Group 4 or 5 increased from 155/year at baseline to 231, 297, and 285 in 2013, 2014, and 2015, respectively (P < 0.05), unrelated to age or racial changes over time. Black men represented 16% of the cohort. Since the USPSTF recommendation against prostate cancer screening, trends toward a substantial upward grade migration and increased volume of cancers were noted in a cohort of nearly 11,000 patients in a real- world clinical practice. Additionally, continuing reductions in cancer detection in the United States may exacerbate these trends. [Rev Urol. 2018;20(3):125–130 doi: 10.3909/riu0815] © 2018 MedReviews®, LLC

A Review of Current Hemostatic Agents and Tissue Sealants Used in Laparoscopic Partial Nephrectomy

Treatment Review

I GalanakisN VasdevN Soomro

Laparoscopic partial nephrectomy (LPN) is currently considered to be one of the most challenging procedures in minimally invasive urological surgery. With an increasing number of renal tumors being managed using LPN, there is now a further interest in the development of techniques and agents to reduce complications associated with the procedure. Hemostasis is of paramount importance during LPN, and hemostatic agents and tissue sealants are now being used commonly during LPN. Despite this, there is a dearth of prospective, randomized, human trials in current literature that compare the various agents. This review evaluates hemostatic agents and tissue sealants being used during LPN as an adjuvant to suturing in human studies.

Deep prostate-specific antigen reduction of at least 90% (PSA90 response) after androgen receptor pathway inhibitor initiation to treat metastatic castration-sensitive prostate cancer (mCSPC) is associated with longer survival. This real-world study evaluated the proportion of androgen receptor pathway inhibitor–naive patients with mCSPC who achieved PSA90 response 6 months after initiating apalutamide or enzalutamide.

Metabolic Syndrome and Urologic Diseases

Mangement Review

Haluk AkpinarIlya Gorbachinsky

Metabolic syndrome (MetS) is a complex entity consisting of multiple interrelated factors including insulin resistance, central adiposity, dyslipidemia, endothelial dysfunction and atherosclerotic disease, low-grade inflammation, and in males, low testosterone levels. MetS has been linked to a number of urologic diseases including nephrolithiasis, benign prostatic hyperplasia and lower urinary tract symptoms, erectile dysfunction, male infertility, female incontinence, and prostate cancer. This article reviews the relationships between MetS and these entities. Urologists need to be cognizant of the impact that MetS has on urologic diseases as well as on overall patient health.[Rev Urol. 2010;12(4):e157-e180 doi: 10.3909/riu0487]© 2010 MedReviews®, LLC

Solitary Fibrous Tumor of the Kidney: A Case Report and Review of the Literature

Case Review

Imane KamaouiAfaf AmartiSanae BennisLaila ChbaniHinde El FatemiTaoufik HarmouchFadl TaziKaoutar Znati

A solitary fibrous tumor (SFT) is an unusual spindle cell neoplasm that usually occurs in the pleura but has recently been described in diverse extrapleural sites. Urogenital localization is rare, and only 19 cases of SFT of the kidney have been described. We report a case of a large SFT clinically thought to be renal cell carcinoma arising in the kidney of a 70-year-old man. The tumor was well circumscribed and composed of a mixture of spindle cells and dense collagenous bands, with areas of necrosis or cystic changes noted macroscopically and microscopically. Immunohistochemical studies revealed reactivity for CD34, CD99, and Bcl-2 protein, with no staining for keratin, S-100 protein, or muscle markers, confirming the diagnosis of SFT. This tumor is benign in up to 90% of cases. The immunohistochemical study is the key to diagnosis. [Rev Urol. 2007;9(1):36-40]

47,XYY Syndrome and Male Infertility

Edmund S SabaneghIna W KimArjun C KhadilkarEdmund Y Ko

Men with 47,XYY syndrome present with varying physical attributes and degrees of infertility. A retrospective chart review was performed on a male infertility and genetic anomaly database. Three patients with 47,XYY were found. Each presented with . 2 years of infertility. All were tall with elevated body mass indices. Scrotal findings ranged from normal to atrophic testicles. Semen analyses demonstrated oligospermia and varying endocrine profiles. Because of the diverse phenotype and potential lack of symptoms, identification and diagnosis of men with 47,XYY syndrome may be difficult. We recommend careful screening of 47,XYY patients and referral to primary physicians for long-term follow-up for increased incidence of health-related comorbidities.

The Emergence of Radioimmunoscintigraphy for Prostate Cancer

Prostate Cancer Imaging

David G McLeodThomas E KeaneInger L RosnerM Scott Wingo

The ability to label tissue-specific antibodies has long been of interest for improving detection and guidance for therapeutic applications. The most studied target for prostate cancer is the prostate-specific membrane antigen, which is upregulated in prostate cancer, hormone-refractive disease, and prostate cancer metastases. Investigations using radioimmunoscintigraphy with the radiolabeled 7E11 antibody capromab pendetide have significantly improved sensitivity for prostate cancer detection compared with standard cross-sectional imaging, based on tissue confirmation of pathologic results. Over the past 5 years, significantly greater image resolution from improved camera technology and the use of co-registration to fuse functional and anatomic (computerized tomography and magnetic resonance imaging) images have dramatically enhanced prostate cancer localization. Outcomes data from several sources have spurred a resurgence in interest in this imaging modality. [Rev Urol. 2006;8(suppl 1):S20-S28]

Cycling Trauma as a Cause of Arterial Priapism in Children and Teenagers

Aldo Franco De RoseIrene ParaboschiGuglielmo ManticaAlexander SzpytkoHilgard AckermannGiovanni De CaroCarlo TerroneGirolamo Mattioli

Bicycle riding has multiple beneficial cardiovascular effects; however, it is a well-documented source of significant urologic injuries. Priapism is a rare condition in children, and occurs primarily because of congenital hematologic diseases or adverse drug reactions. A pediatric clinical case and literature review of a high-flow priapism secondary to cycling trauma is described here to highlight their etiopathologic correlation. Bicycle riding trauma is a rare but possible cause of high-flow priapism in children, and a high index of suspicion should ensure appropriate management.

Fertility and the Aging Male

Condition Review

Randall B MeachamIsiah HarrisCarolyn FronczakLauren Roth

In the United States since 1980, the birth rate in women aged &gt; 35 years has increased by nearly 60%, whereas the birth rate for women aged 20 to 34 years has increased by only 10%. The trend in parenthood at an older age has also been seen in men. Since 1980, the fertility rate for men in their 30s has increased by 21% and for men aged 40 years and older, the rate has increased nearly 30%. In contrast, the fertility rate in men younger than age 30 years has decreased by 15%. Age-related infertility will continue to be a problem. A basic understanding of the issues is critical for health care professionals so that they can effectively counsel patients who are considering a delay in childbearing for social reasons or for those seeking fertility treatments. This review details the changes in fertility seen in the aging male. [Rev Urol. 2011;13(4):e184-e190 doi: 10.3909/riu0538] © 2011 MedReviews®, LLC

An Unusual Presentation of Primary Male Genital Tuberculosis

Imane KamaouiMohamed AmineBrahim EddafaliA Ibn SellamZakaria DahamiSaid Mohamed MoudouniIsmail Sarf

Urogenital tuberculosis is a rare disease; however, it is the second most common location for tuberculosis after the lung. Currently, incidence of urogenital tuberculosis is increasing due to factors such as a higher prevalence of immunosuppression (especially that caused by human immunodeficiency virus infection) and drug abuse. Herein a new case of male genital primary tuberculosis is reported presenting as a scrotal tumor; the originality of this observation lies in its unusual pseudotumor form.

Prostate Biopsy Characteristics: A Comparison Between the Pre- and Post-2012 United States Preventive Services Task Force (USPSTF) Prostate Cancer Screening Guidelines

Navin ShahVladimir IoffeThomas HuebnerIvelina Hristova

To compare prostate cancer (PCa) characteristics diagnosed by prostate biopsy (Pbx) in the 3 years before and after the 2012 United States Preventive Services Task Force (USPSTF) recommendations for PCa screening, we completed a retrospective comparative analysis of 402 sequential PCa patients diagnosed from 2010 to 2012 (3 years) with 552 PCa patients diagnosed from 2015 to 2017 (3 years). Data was collected on patient age, race, total number of biopsies performed, prostate specific antigen (PSA), Gleason sum score (GSS), and digital rectal examination (DRE). The data was analyzed to determine whether the 2012 USPSTF screening recommendations affected PCa characteristics. Two study groups were defined, Group A and Group B, prior to and after the 2012 USPSTF screening recommendations, respectively. In Group A (pre- 2012 USPSTF recommendations), 567 patients/year underwent a Pbx versus Group B, 398 patients/year, a 30% reduction post-USPSTF. The annual positive Pbx rate for Group A is 134/year versus Group B 184/year, a 37.3% increase post-USPSTF. Group A had high-grade PCa (GSS 7-10) in 51.5% versus Group B in 60.1%, an 8.6% increase post-USPSTF. In Group B, the total number of positive biopsies was increased by 100%. This study shows that in Group B, the Pbx rate decreased by 30% but the annual PCa detection rate increased by 37%. High-grade GSS (7-10) PCa increased by 8.6%. Despite a reduction in the total number of prostate biopsies by 30%, there was a 100% increase in the total number of positive prostate biopsies.
