Shock Wave Lithotripsy and Renal Hemorrhage

Case Review

J Kellogg ParsonsJonathan SilbersteinCharles M Lakin

Although shock wave lithotripsy is a safe and efficacious treatment for nephrolithiasis, the most common acute complication is renal hemorrhage. Shock wave–induced renal hemorrhage is a potentially devastating injury if not promptly recognized and treated appropriately. The authors report a large perirenal hematoma occurring after shock wave lithotripsy and review the causes, prevention, and treatment of shock wave–induced renal hemorrhage.

Long-term Survival From Muscle-invasive Bladder Cancer With Initial Presentation of Symptomatic Cerebellar Lesion: The Role of Selective Surgical Extirpation of the Primary and Metastatic Lesion

Ganesh K KarthaJoseph SanfrancescoEsther UdojiHemant Chaparala (4)Donna HanselJ Stephen Jones

A 59-year-old man was diagnosed with urothelial carcinoma involving an isolated cerebellar metastasis after presenting to the emergency department for headache complaints. After selective surgical excision of the symptomatic brain lesion and delayed cystectomy due to intractable hematuria, he survived 11 years without evidence of recurrence or subsequent systemic chemotherapy. He eventually expired after delayed recurrence in the lung, supraclavicular lymph node, and brain. To our knowledge, this is the only case of prolonged survival from urothelial carcinoma after selective surgical extirpation of the primary and metastatic lesion without subsequent systemic chemotherapy.

A Review of Transplantation Practice of the Urologic Organs: Is It Only Achievable for the Kidney?

Treatment Update

Jack Donati-BourneHarry W RobertsYaseen RajjoubRobert A Coleman

Transplantation is a viable treatment option for failure of most major organs. Within urology, transplantation of the kidney and ureter are well documented; however, evidence supporting transplantation of other urologic organs is limited. Failure of these organs carries significant morbidity, and transplantation may have a role in management. This article reviews the knowledge, research, and literature surrounding transplantation of each of the urologic organs. Transplantation of the penis, testicle, urethra, vas deferens, and bladder is discussed. Transplantation attempts have been made individually with each of these organs. Penile transplantation has only been performed once in a human. Testicular transplantation research was intertwined with unethical lucrative pursuits. Interest in urethra, bladder, and vas deferens transplantation has decreased as a result of successful surgical reconstructive techniques. Despite years of effort, transplantations of the penis, testicle, urethra, vas deferens, and bladder are not established in current practice. Recent research has shifted toward techniques of reconstruction, tissue engineering, and regenerative medicine. [Rev Urol. 2015;17(2):69–77 doi: 10.3909/riu0659] © 2015 MedReviews®, LLC

Hypocitraturia: Pathophysiology and Medical Management

Management Review

Dean G AssimosJack M Zuckerman

Low urinary citrate excretion is a known risk factor for the development ofkidney stones. Citrate inhibits stone formation by complexing with calciumin the urine, inhibiting spontaneous nucleation, and preventing growth andagglomeration of crystals. Hypocitraturia is a common metabolic abnormalityfound in 20% to 60% of stone formers. It is most commonly idiopathic inorigin but may be caused by distal renal tubular acidosis, hypokalemia, boweldysfunction, and a high-protein, low-alkali diet. Genetic factors, medications,and other comorbid disorders also play a role. Hypocitraturia should be managedthrough a combination of dietary modifications, oral alkali, and possiblylemonade or other citrus juice–based therapy. This review concerns thepathophysiology of hypocitraturia and the management of stone formersafflicted with this abnormality.[Rev Urol. 2009;11(3):134-144 doi:10.3909/riu0424]© 2009 MedReviews®, LLC

Contemporary Approaches to Diagnosing Prostate Cancer

Ashley E. RossAlon LazarovichAaron S. DahmenAbhinav SidanaJack MillotJonathan E. ShoagHangcheng FuJohn Eifler

The diagnosis of prostate cancer (PCa) has changed substantially over the last decade. An increased understanding of disease behavior has led to the development of more specific biomarkers that may limit the numbers of prostate biopsies performed as well as the overdiagnosis of low-grade disease. We have concurrently seen the refinement of imaging techniques such as multiparametric magnetic resonance imaging (mpMRI), which can also limit overdiagnosis and aid in the discovery of clinically significant disease. We now have various options for performing ultrasound-guided biopsies, including transperineal and transrectal approaches. In this article, we gather perspectives on contemporary pathways toward the diagnosis of PCa from experts practicing in large urology practice groups and academia.

Barriers to Accessing Urethroplasty

Treatment Update

David O SussmanGordon A BrownMichael J ConsoloKirin K SyedChristopher RobisonJacob McFaddenDavid I ShalowitzBradley D Figler

Urethroplasty is an effective treatment for men with anterior urethral strictures, but is utilized less frequently than ineffective treatments such as internal urethrotomy. We sought to identify provider-level barriers to urethroplasty. An anonymous online survey was emailed to all Mid-Atlantic American Urological Association members. Six scenarios in which urethroplasty was the most appropriate treatment were presented. Primary outcome was recommendation for urethroplasty in ≥ three clinical scenarios. Other factors measured include practice zip code, urethroplasty training, and proximity to a urethroplasty surgeon. Multivariate logistic regression identified factors associated with increased likelihood of urethroplasty recommendation. Of 670 members emailed, 109 (16%) completed the survey. Final analysis included 88 respondents. Mean years in practice was 17.2. Most respondents received formal training in urethroplasty: 43 (49%) in residency, 5 (6%) in fellowship, and 10 (11%) in both; 48 respondents (55%) had a urethroplasty surgeon in their practice, whereas 18 (20%) had a urethroplasty surgeon within 45 minutes of his or her primary practice location. The only covariate that was associated with an increased likelihood of recommending urethroplasty in ≥ three scenarios was formal urethroplasty training. Most members (68%) reported no barriers to referring patients for urethroplasty; the most common barriers cited were long distance to urethroplasty surgeon (n = 13, 15%) and concern about complications (n = 8, 9%). Urethroplasty continues to be underutilized in men with anterior urethral strictures, potentially due to lack of knowledge dissemination and access to a urethroplasty surgeon. Appropriate urethroplasty utilization may increase with greater exposure to urethroplasty in training. [Rev Urol. 2016;18(4):188-193 doi: 10.3909/riu0731] © 2016 MedReviews®, LLC

Erectile Dysfunction and Essential Hypertension: The Same Aging-related Disorder?

Screening Update

Raul I ClavijoMartin MinerJacob Rajfe

An erection is a mechanical event dependent primarily on corporeal vascular dynamics wherein arterial inflow and storage of blood within the corpora is greater than the egress of blood from the corpora. The most common cause of erectile dysfunction (ED) is the inability of the corporal tissue to store the blood within the corporal sinusoids once inflow into the corpora begins. This failure to store is primarily due to a corporal smooth muscle dysfunction and, in most men, is most likely an aging-related occurrence. Because the corporal smooth muscle is embryologically and physiologically indistinguishable from the smooth muscle within our arterial system, the authors hypothesize that the aging-related dysfunction that occurs within the penis also occurs within the arterial system, and that this smooth muscle dysfunction within the arterial media is most likely the cause of what is called essential hypertension. This panvascular smooth muscle myopathy could explain why hypertension is the most common comorbidity associated with ED and appears to indicate that both ED and essential hypertension are the same disorder, albeit in two different organ systems.

Estrogenic Side Effects of Androgen Deprivation Therapy

Treatment Update

Michael S CooksonJames A EasthamTheresa A GuiseMichael G OefeleinMatthew R SmithCelestia Higano

Androgen deprivation therapy (ADT) is part of standard therapy for locally advanced or metastatic prostate cancer and is frequently used in men with a rising prostate-specific antigen following radical prostatectomy or radiation therapy. In some men, ADT may be administered for years or even decades. The intended therapeutic effect of ADT is testosterone deficiency. Because estrogen is a normal metabolite of testosterone, ADT also results in estrogen deficiency. ADT has a variety of adverse effects, many of which are primarily related to estrogen deficiency. Bone mineral density may decrease by 4% to 13% per year in men receiving ADT. The fracture rate for patients on ADT averages 5% to 8% per year of therapy. Hot flashes, gynecomastia, and breast tenderness are common side effects associated with ADT. In the clinic, minimum baseline testing should include weight measurement, blood pressure reading, and fasting lipid panel and serum glucose tests. Currently, there are no large outcome trials in men on ADT testing the available therapies for adverse effects. No therapies are specifically approved for treatment of adverse effects in men on ADT. Although some therapies can be used for a single indication (based upon small studies), there is currently no agent to treat the multiple estrogenic side effects of ADT.

The Use of Vacuum Erection Devices in Erectile Dysfunction After Radical Prostatectomy

Management Update

Nikhil VasdevKimberley HoylandJames Adshead

The risk of postoperative erectile dysfunction (ED) following radical prostatectomy (RP) is reported to be between 14% and 89%. With an increase in the detection of prostate cancer in younger men, there is a greater emphasis on the appropriate management of ED following RP. A number of options are available to manage ED after RP, including phosphodiesterase-5 inhibitors, intracorporeal injections, intraurethral alprostadil, and vacuum erection devices (VEDs). Penile rehabilitation programs are increasingly used to facilitate the return of natural postoperative erections; the VED is an ideal therapy given that it increases blood flow and oxygenation to the corpora to reverse the changes that result in ED after RP.

The Role of Minimally Invasive Surgical Techniques in the Management of Large-gland Benign Prostatic Hypertrophy

Management Update

Ojas ShahHerbert LeporGanesh SivarajanMichael S BorofskyJames E Lingeman

Lower urinary tract symptoms (LUTS) secondary to benign prostatic hypertrophy (BPH) are among the most common medical issues for aging men. Population-based studies suggest that 13.8% of men in their 40s and more than 40% of men over age 60 have BPH. When LUTS are refractory to medical therapy and bothersome enough to warrant surgical intervention, transurethral resection of the prostate and open simple prostatectomy have been the historical reference-standard procedures for decades. Both procedures are highly effective and offer durable improvements in urinary functional outcomes. However, they also have the potential for considerable perioperative complications and morbidity. In an effort to limit surgical morbidity, a variety of minimally invasive surgical techniques to treat BPH have been introduced. Herein we present a comprehensive, evidence-based review of the efficacy and safety profile of modern minimally invasive treatments for large-gland BPH.

Contemporary Management of Bulbar Urethral Strictures

Management Review

Andrew J CohenRoss S LiaoErica SternJames E Wright

Urethral stricture disease (USD) is a progressive scar-forming disease commonly encountered by urologists and is challenging to manage. USD most frequently occurs in the bulbar urethra. Patients typically present with chronic obstructive voiding symptoms but may develop recurrent urinary tract infections, detrusor failure, or renal disease. The authors review the pathophysiology, diagnostic workup, and evidence-based management of bulbar urethral strictures (BUS). There are multiple surgical options to treat BUS. Endoscopic techniques (eg, dilation and urethrotomy) are suitable for the initial management of short strictures but new evidence-based guidelines recommend against repeated endoscopic treatment. Urethroplasty is the gold standard treatment for BUS of all lengths, with anastomotic techniques appropriate for strictures <2 cm and tissue substitution performed for longer strictures. New techniques, such as non-transecting urethroplasty, lack long-term data but may represent a paradigm shift in the field. Future treatments may utilize tissue-engineered grafts and agents that inhibit inflammation and scar formation. [Rev Urol. 2020;22(4):139–151] © 2021 MedReviews®, LLC

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]
