Physician-Owned Hospitals: A Look at the Numbers

Robert A. DowlingMara Holton

Physician-owned hospitals are sometimes characterized as examples of inappropriate self-referral. This perception contributes to legislation and regulation that constrain physician ownership. The true scope of physician ownership and its impact are incompletely understood. This study aimed to better define the current landscape of physician ownership in US hospitals to inform policy making in this area.

The Rationale for Optimal Combination Therapy With Sipuleucel-T for Patients With Castration-resistant Prostate Cancer

Treatment Review

Neal D ShoreRaoul S ConcepcionChristopher M PieczonkaVladimir MouravievNeil MariadosRobert B SimsMark Emberton

Immunotherapy encourages the recipient’s own immune response to destroy cancer cells, and current evidence suggests that immunotherapies may be most beneficial in early metastatic castration-resistant prostate cancer (mCRPC). Sipuleucel-T is the first therapeutic cancer vaccine to be approved by both the US Food and Drug Administration and European Medicines Agency for the treatment of asymptomatic or minimally symptomatic mCRPC. Combining immunotherapy with other treatments may have potent anticancer effects; cytoreductive therapies can release tumor antigens and promote a proinflammatory environment that could augment immunotherapies. However, some cytoreductive agents or coadministered drugs may be immunosuppressive. Understanding these interactions between different mCRPC treatment modalities may offer further potential to improve patient outcomes.

Spurious Hypocalcemia After Gadodiamide-Enhanced Magnetic Resonance Imaging: A Case Report and Review of the Literature

Case Review

James G CairidiChristopher D MooreRobert C Newman

Gadolinium-enhanced magnetic resonance imaging is a diagnostic modality widely used in urologic practice. We report on a 54-year-old woman in whom a critically low serum calcium level was measured with standard colorimetric assay after gadodiamide-enhanced magnetic resonance imaging. The same phenomenon was noted in 2 other patients seen in our practice. Repeat serum calcium measurements performed several hours later were within normal limits. Commercially available gadolinium-based contrast agents might precipitate critically low serum calcium values when measured by standard colorimetric assay. Physician awareness of gadodiamide-induced spurious hypocalcemia might prevent unnecessary therapeutic interventions. [Rev Urol. 2006;8(3):165-168]

Proton Beam Therapy for Localized Prostate Cancer 101: Basics, Controversies, and Facts

Treatment Update

Eric S WisenbaughPaul E AndrewsRobert G FerrigniSteven E SchildSameer R KeoleWilliam W WongSujay A Vora

Proton beam therapy for prostate cancer has become a source of controversy in the urologic community, and the rapid dissemination and marketing of this technology has led to many patients inquiring about this therapy. Yet the complexity of the technology, the cost, and the conflicting messages in the literature have left many urologists ill equipped to counsel their patients regarding this option. This article reviews the basic science of the proton beam, examines the reasons for both the hype and the controversy surrounding this therapy, and, most importantly, examines the literature so that every urologist is able to comfortably discuss this option with inquiring patients.

Use of Spermatic Cord Block Systematically Identifies a Paraspinal Tumor as Source of Orchialgia

Mason HoltelRobert J Baranello JrAllyson HalePatrick Springhart

Orchialgia is a common urologic complaint with a myriad of etiologies. Workup for orchialgia requires a broad differential diagnosis and a thorough understanding of relevant anatomy. We report the case of a 43-year-old man who presented to a urologist with right testicular pain. Following a negative workup, the patient received a spermatic cord block for therapeutic and diagnostic purposes. Two months after the block, the patient returned with new complaints of ipsilateral inner thigh paresthesias, suggesting a pathologic process proximal to the genital branch of the genitofemoral nerve. A subsequent MRI of the lumbosacral spine revealed a paraspinal mass involving nerve roots at L1-2. We highlight the utility of the spermatic cord block and its role in the diagnosis of a paraspinal tumor as an uncommon cause of orchialgia. [Rev Urol. 2019;21(1):49–52] © 2019 MedReviews®, LLC

Cryptozoospermia Associated With Genital Tucking Behavior in a Transwoman

James T TrusslerRobert J Carrasquillo

Transwomen may elect to pursue fertility preservation prior beginning hormonal treatment or proceeding with gender-affirming surgery. To date, there has been little research specifically investigating factors influencing fertility and preservation thereof among transwomen. Here, we review the case of a transwoman who engaged in genital tucking behavior presenting with severe oligospermia, and we review the literature regarding transgender fertility preservation and the role of the heat stress hypothesis with regards to this common behavior.

Male Urinary Incontinence: Prevalence, Risk Factors, and Preventive Interventions

Systematic Review

Tatyana A ShamliyanJean F WymanRyan PingTimothy J WiltRobert L Kane

Urinary incontinence (UI) in community-dwelling men affects quality of lifeand increases the risk of institutionalization. Observational studies and randomized,controlled trials published in English from 1990 to November 2007on the epidemiology and prevention of UI were identified in several databasesto abstract rates and adjusted odds ratios (OR) of incontinence, calculateabsolute risk difference (ARD) after clinical interventions, and synthesizeevidence with random-effects models. Of 1083 articles identified, 126 wereeligible for analysis. Pooled prevalence of UI increased with age to 21% to32% in elderly men. Poor general health, comorbidities, severe physicallimitations, cognitive impairment, stroke (pooled OR 1.54; 95% confidenceinterval [CI], 1.14-2.1), urinary tract infections (pooled OR 3.49; 95%CI, 2.33-5.23), prostate diseases, and diabetes (pooled OR 1.36; 95% CI,1.14-1.61) were associated with UI. Treatment with tolterodine alone (ARD0.17; 95% CI, 0.02-0.32) or combined with tamsulosin (ARD 0.17; 95% CI,0.08-0.25) resulted in greater self-reported benefit compared with placebo.Radical prostatectomy or radiotherapy for prostate cancer compared withwatchful waiting increased UI. Short-term prevention of UI with pelvic floormuscle rehabilitation after prostatectomy was not consistently seen acrossrandomized, controlled trials. The prevalence of incontinence increased with ageand functional dependency. Stroke, diabetes, poor general health, radiation, andsurgery for prostate cancer were associated with UI in community-dwellingmen. Men reported overall benefit from drug treatments. Limited evidence ofpreventive effects of pelvic floor rehabilitation requires future investigation.[Rev Urol. 2009;11(3):145-165 doi:10.3909/riu0416]© 2009 MedReviews, LLC

Accuracy in 24-hour Urine Collection at a Tertiary Center

Dean G AssimosKyle WoodCarter BoydDustin WhitakerOmotola AshorobiRobert OsterLisa HarveyRoss P Holmes

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

Endoscopic Management of Genitourinary Foreign Bodies

Joseph B SongYoussef S TanaghoMohammed HaseebuddinBrian M BenwayAlana C DesaiSam B BhayaniRobert S Figenshau

Retrieval of foreign bodies from the genitourinary system, most commonly inserted for sexual satisfaction or as a result of a psychiatric illness, can pose a significant surgical challenge. Due to their breadth of size, shape, and location within the genitourinary system, endoscopic management can be difficult. Here, we review the management of four cases of foreign object insertion into the genitourinary system and their outcomes and management.

Extent of Pelvic Lymph Node Dissection During Radical Cystectomy: Is Bigger Better?

Management Review

Debasish SundiRobert S SvatekMatthew E NielsenTrinity J Bivalacqua

Pelvic lymph node dissection (PLND) is a standard component of radical cystectomy (RC) for bladder cancer. The optimal anatomic PLND template remains undefined. An extended PLND template can potentially improve survival through the eradication of micrometastatic disease and improved pathologic staging. However, this benefit could be compromised by a potential increase in perioperative complications and cost. Two randomized controlled clinical trials that will clarify this question are ongoing. Many important retrospective studies have provided insights into the optimal PLND extent. Here the authors review the key evidence that informs how urologists may tailor the PLND template during RC depending on patient and tumor characteristics.
