Accuracy in 24-hour Urine Collection at a Tertiary Center

Robert OsterRoss P HolmesLisa HarveyOmotola AshorobiDustin WhitakerCarter BoydKyle WoodDean G Assimos

There is a paucity of studies addressing the accuracy of 24-hour urine collection for assessing stone risk parameters. Collection accuracy is thought to be essential for assigning optimal therapy for stone prevention. The objective of this study was to determine factors associated with accurate and inaccurate collections. During a 2-year period (2015-2016), 241 stone formers completed 24-hour urine collections. They were divided into accurate collectors (AC), defined as at least one accurate urine collection, and inaccurate collectors (IC). Accuracy was assessed by 24-hour urine creatinine (Cr) excretion indexed to body weight (normal: males, 20-25 mg Cr/kg; females, 15-20 mg Cr/kg). Demographic data analyzed included age, gender, race, insurance status, partner status, income, and education. Statistical analysis methods included the chi-square test, Fisher’s exact test, and the two-group t-test. Average age was 50.7 years at the time of collection; 50.2% were men, 86% were white, and 14% were black. Overall, 51.0% of collections were inaccurate. There was no statistical significance between AC and IC for gender (P = 0.85), race (P = 0.90), insurance status (P = 0.85), recurrence (P = 0.87), stone type (P = 0.57), education (P = 0.35), income (P = 0.42), or poverty (P = 0.35). Older age (P = 0.017) and having a partner (P = 0.022) were significantly associated with AC. The high rate of inaccurate 24-hour urine collections is a concern. The only factors we identified as influencing collection accuracy were age and partner status. These results underscore the importance of developing methods to improve the accuracy of collecting 24-hour urine samples. [Rev Urol. 2018;20(3):119–124 doi: 10.3909/riu0807] © 2018 MedReviews®, LLC

Hemostasis During Urologic Surgery: Fibrin Sealant Compared With Absorbable Hemostat

David M. AlbalaJonathan BatillerLiza OvingtonJessica ShenJohn AlbaneseBogdan IlieRichard KocharianJerome B Riebman

In the United States, fibrin sealants have been used to achieve hemostasis for nearly two decades. Although their clinical utility was first demonstrated in cardiac surgery, their effectiveness and safety have since been demonstrated to extend to a wide array of procedures. Fibrin sealants typically contain two components—fibrinogen and thrombin—that are combined and delivered simultaneously to a target bleeding site in order to achieve hemostasis. However, many commercial formulations contain other additional components, such as antifibrinolytic agents, that have been associated with adverse outcomes. This subanalysis compares the safety and effectiveness of a fibrin sealant versus an absorbable hemostat for achieving hemostasis during urologic procedures with mild to moderate bleeding.

Revisiting the Role of Testosterone: Are We Missing Something?

Thereapeutic Update

Loren Wissner GreeneFrank A LiporaceRichard S YoonMichael ScordoVineet Tyagi

Testosterone is a pleiotropic hormone that plays an important role in the human body. Classically, testosterone was thought to be predominantly involved in androgenesis and physiology in boys and men. Through its conversion to estrogen, testosterone affects bone health, including bone density. Recently, there has been a renewed interest in the systemic role of testosterone in pain, well-being, and cardiovascular function in women and men alike. In this review, we discuss the historic significance of testosterone, its traditionally known physiology, and its molecular and cellular effects. We also discuss evidence for testosterone’s lesser known effects, including its role in women’s health. We suggest a need to revisit the clinical role of testosterone given its potential for applications to treat mood, cognitive health, and other illnesses, and its anabolic role in bone and muscle; we also suggest consideration of the current debate on risks of its use.

Intracavitary Immunotherapy and Chemotherapy for Upper Urinary Tract Cancer: Current Evidence

Systematic Review

Angelica GrassoAugusto MaggioniElena TondelliMarco RossoSara MelegariCarlo MarenghiNicola MacchioneGabriele CozziRoberto BianchiLuca Carmignani

A review of the literature was performed to summarize current evidence regarding the efficacy of topical immunotherapy and chemotherapy for upper urinary tract urothelial cell carcinoma (UUT-UCC) in terms of post-treatment recurrence rates. A Medline database literature search was performed in March 2012 using the terms upper urinary tract, urothelial cancer, bacillus Calmette-Guérin (BCG), and mitomycin C. A total of 22 full-text articles were assessed for eligibility, and 19 studies reporting the outcomes of patients who underwent immunotherapy or chemotherapy with curative or adjuvant intent for UUT-UCC were chosen for quantitative analysis. Overall, the role of immunotherapy and chemotherapy for UUT-UCC is not firmly established. The most established practice is the treatment of carcinoma in situ (CIS) with BCG, even if a significant advantage has not yet been proven. The use of BCG as adjuvant therapy after complete resection of papillary UUT-UCC has been studied less extensively, even if recurrence rates are not significantly different than after the treatment of CIS. Only a few reports describe the use of mitomycin C, making it difficult to obtain significant evidence. [Rev Urol. 2013;15(4):145-153 doi: 10.3909/riu0579] © 2014 MedReviews®, LLC

Adenocarcinoma of the Urethra With Mucinous Features

Lucas ReddArthi SatyanarayanAnthony DyerJonathan WalkerAndrew Wright

Primary adenocarcinoma of the female urethra is a rare malignancy. Previous studies hypothesize multiple origins, including periurethral glands or intestinal metaplasia. We report a case of a 60-year-old white woman with adenocarcinoma of the urethra who initially presented with obstructive voiding complaints secondary to a urethral mass. Wide local excision revealed invasive adenocarcinoma of the urethra with mucinous features. There was intestinal metaplasia adjacent to the tumor, as well as separate identification of intestinal metaplasia along the urethra. Ultimately, the patient underwent radical cystectomy with ileal conduit urinary diversion with no evidence of recurrence, indicating the role of early identification and surgical intervention for such cases.

Spinal Dysraphism: A Neurosurgical Review for the Urologist

Management Review

André A FigueiredoLuis M PérezAndré N BastosJosé Murillo B Netto

Spinal neural tube defects are congenital malformations of the spine and spinal cord (eg, myelomeningocele) and are frequently seen in pediatric urology practice. These neurologic problems have many consequences in a child’s life and affect different parts of the body, such as the brain, spinal cord, limbs, bladder, and bowels. Because of the complexity and neurologic aspects of spinal dysraphism, many related terms and aspects of the disease are unfamiliar to the urologist. This review addresses some of the most commonly used neurosurgical terms and concepts related to spinal dysraphism.[Rev Urol. 2009;11(2):71-81]

Metastatic Urethral Melanoma: Case Report and Review of the Literature

Luiz Ronaldo AlbertiRafaela Saint-Clair Pimentel Mafra De OliveiraBruno Moraes Vasconcelos

Melanoma is a cancer that originates from melanocytes, is predominant in adults with white skin, represents 4% of skin cancers, and has high possibility of forming metastasis. This review reports on the case of a young man, age 36 years, previously diagnosed with melanoma. The patient complained of obstructive urinary symptoms and, while he was undergoing a cystoscopy, it was discovered that he had a lesion corresponding with metastatic melanoma of the prostatic urethra, which occluded almost the entire urethra and resulted in blocked urinary flow. He underwent a transurethral resection of the prostate, followed by resection of the lesion. After the procedure, he had good urinary flow and is currently on follow-up.

Using 17-OHP as Serum Biomarker to Monitor Therapy in Patients With Hypogonadotropic Hypogonadism

R RamasamyP PatelM NarasimmaA Mouzannar

Exogenous testosterone administration decreases intratesticular testosterone (ITT) significantly, an essential hormone for spermatogenesis. Therefore, treatment of patients with hypogonadotropic hypogonadism (HH) who desire infertility can be challenging. These patients are treated with recombinant follicle-stimulating hormone (FSH), clomiphene citrate, and human chorionic gonadotropin (hCG) to increase their ITT. However, there is no approved serum biomarker for ITT and it can only be measured via invasive testicular biopsy or aspiration. Previous authors have speculated that serum 17-hydroxyprogestrone (17-OHP) can be used as serum biomarker for ITT. In our case report, we demonstrate increase in 17-OHP associated with spermatogenesis after commencing treatment for infertility in patient with HH.

The Emergence of Radioimmunoscintigraphy for Prostate Cancer

Prostate Cancer Imaging

Inger L RosnerM Scott WingoThomas E KeaneDavid G McLeod

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]
