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.

Calyceal Diverticula: A Comprehensive Review

Disease State Review

Zeph OkekeNikhil WaingankarSamih HayekArthur D Smith

Calyceal diverticula are rare outpouchings of the upper collecting system that likely have a congenital origin. Stones can be found in up to 50% of calyceal diverticula, although, over the combined reported series, 96% of patients presented with stones. Diagnosis is best made by intravenous urography or computed tomography urogram. Shock wave lithotripsy (SWL) is an option for first-line therapy in patients with stone-bearing diverticula that have radiologically patent necks in mid- to upper-pole diverticula and small stone burdens. Stone-free rates are the lowest with SWL, although patients report being asymptomatic following therapy in up to 75% of cases with extended follow-up. Ureteroscopy (URS) is best suited for management of anteriorly located mid- to upper-pole diverticular stones. Drawbacks to URS include difficulty in identifying the ostium and low rate of obliteration. Percutaneous management is best used in posteriorly located mid- to lower-pole stones, and offers the ability to directly ablate the diverticulum. Percutaneous nephrolithotomy remains effective in the management of upper-pole diverticula, but carries the risk of pulmonary complications unless subcostal access strategies such as triangulation or renal displacement are used. Laparoscopic surgery provides definitive management, but should be reserved for cases with large stones in anteriorly located diverticula with thin overlying parenchyma, and cases that are refractory to other treatment. This article reviews the current theories on the pathogenesis of calyceal diverticula. The current classification is examined in addition to the current diagnostic methods. Here we summarize an extensive review of the literature on the outcomes of the different treatment approaches. [ Rev Urol. 2014;16(1):29-43 doi: 10.3909/riu0581] © 2014 MedReviews®, LLC

A Novel Approach to Mesh Revision After Sacrocolpopexy

Nima M ShahMelissa L DawsonRebecca RinkoKristene E Whitmore

Pelvic organ prolapse (POP) is the herniation of pelvic organs to or beyond the vaginal walls. POP affects 50% of parous women; of those women, 11% will need surgery based on bothersome symptoms. Transvaginal mesh has been used for vaginal augmentation since the 1990s. Complications from mesh use are now more prominent, and include chronic pelvic pain, dyspareunia, vaginal mesh erosion, and urinary and defecatory dysfunction. Presently, there is no consensus regarding treatment of these complications. Reported herein are two cases of women with defecatory dysfunction and pain after sacrocolpopexy who underwent mesh revision procedures performed with both urogynecologic and colorectal surgery.

Reducing Infectious Complications Following Transrectal Ultrasound-guided Prostate Biopsy: A Systematic Review

Systematic Review

Nirmish SinglaJordon T WalkerClaus G Roehrborn

A rise in antimicrobial resistant uropathogens has generated a global increase in infections following transrectal ultrasound-guided prostate biopsy (TRUS-Bx). We performed a systematic search of Ovid MEDLINE® and PubMed to comprehensively review strategies to mitigate infections. Of 1664 articles retrieved, 62 were included. The data suggest that augmented prophylaxis and povidone-iodine bowel preparation warrant consideration in regions with high rates of antimicrobial resistance. Transperineal biopsy may be a safer, equally effective alternative to TRUS-Bx in select cases. Recent international travel appears to increase patients’ risk for experiencing infections. These findings can aid clinicians in minimizing post-TRUS-Bx infectious complications. [Rev Urol. 2016;18(2):73-89 doi: 10.3909/riu0713] © 2016 MedReviews®, LLC

Leptomeningeal Carcinomatosis of Prostate Cancer: A Case Report and Review of the Literature

Elad NeemanNoriko SalamonMatthew Rettig

Leptomeningeal carcinomatosis is a rare complication of prostate cancer. It is likely underdiagnosed as suggested by autopsy studies and is expected to become more prevalent with increasing survival of prostate cancer patients. Prostate cancer leptomeningeal carcinomatosis is associated with rapid functional decline and a median survival of approximately 1 month. Diagnosis is challenging because the clinical manifestations are varied, and no gold-standard diagnostic approach exists. Treatment of prostate cancer leptomeningeal carcinomatosis is not standardized and multiple approaches have been reported, mostly as case studies. Herein we report a case of a 73-year-old patient with metastatic castration-resistant prostate cancer who presented to our clinic with subacute cognitive decline, ataxia, and urinary incontinence, and was found to have leptomeningeal carcinomatosis.

The QT Interval and Selection of Alpha-Blockers for Benign Prostatic Hyperplasia

Treatment Update

Herbert LeporNorman E LeporLawrence A HillRichard G Trohman

The QT interval is the electrocardiographic manifestation of ventricular depolarization and repolarization. Drug-induced long QT syndrome is characterized by acquired, corrected QT (QTc) interval prolongation that is associated with increased risk of torsade de pointes. Every physician must recognize if the drugs he or she prescribes prolongs the QTc interval, especially if the drug is prescribed for a chronic condition in older patients who are on polypharmacy. The evolution of alpha-blockers for the treatment of benign prostatic hyperplasia has allowed the development of drugs that are easier to administer and better tolerated. Because alpha-blockers generally have equivalent efficacy, this class of drugs is typically differentiated by safety and side effects. Studies suggest that alpha-blockers may vary in regard to their effect on the QT interval, and, therefore, on their predisposition to cause potentially life-threatening ventricular arrhythmias.

Irreversible Electroporation for Prostate Cancer as Salvage Treatment Following Prior Radiation and Cryotherapy

Katie S MurrayOguz AkinJonathan A Coleman

Salvage treatment options after localized primary treatment failure of prostate cancer are limited and associated with risk for serious complications. We report on the management details of a 57-year-old African American man treated with partial-gland ablation using irreversible electroporation following local recurrence after brachytherapy and prior salvage cryoablation. Therapeutic and functional outcomes were assessed by conventional means, including serum prostate-specific antigen values and prostate biopsy results.

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.

Immunotherapy in Urological Tumors

Treatment Review

Nikhil VasdevAnand SharmaNarin SuleymanOliver Jones

The past decade has seen significant improvement in our understanding of tumor biological features, which has led to use of anti-programmed-death 1 (PD-1) and anti-PD ligand-1 (PD-L1) agents and cytotoxic T lymphocytes antigen 4 (CTLA-4) inhibitors in a multitude of cancers. These immunotherapeutic agents have shown activity in melanoma, lung, head and neck, colorectal, urological, and other cancers. This article details the use of immunotherapy agents in urothelial, renal, prostate, and testicular tumors. [Rev Urol. 2019;21(1):15–20] © 2019 MedReviews®, LLC

Prostate-Specific Antigen: Any Successor in Sight?

Diagnostic Review

Aniebietabasi S ObortMary B AjadiOluyemi Akinloye

Prostate cancer (PCa) is the most frequently diagnosed malignancy and the second leading cause of cancer death in men in the United States and other parts of the world. The lifetime risk of being diagnosed with PCa is approximately 16%. At present, the only widely accepted screening tools for PCa are prostate-specific antigen (PSA) and digital rectal examination. PSA is known to be prostate specific, but not PCa specific, and hence lacks the sensitivity to detect a large number of tumors, especially during the early stages. The PSA level is also known to be affected by many factors, such as medication, inflammation (benign prostatic hyperplasia and prostatitis), and urologic manipulation; hence, the controversy regarding the appropriate level of serum PSA that should trigger a biopsy or have clinical relevance to prostate metastases. Attempts to determine the level of prostate cells in peripheral blood by reverse transcriptase polymerase chain reaction did not significantly improve cancer diagnosis or predict postoperative failure. Therefore, the search continues for a novel biomarker or a panel of markers as well as other possible interventions to improve the use of PSA. This article reviews several possibilities.

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

Laparoscopic Nephrectomy for Pyonephrosis During Pregnancy: Case Report and Review of the Literature

Onkar SinghNand Kishore ArvindShilpi Singh GuptaSurbhi SahayKutub AliAnand Dharaskar

The maternal and fetal complications of pyonephrosis during pregnancy can be devastating, thus the call for urgent but safe intervention. Laparoscopic nephrectomy has been used safely and effectively in nonpregnant patients with pyonephrotic kidney. We report on a case of a 28-year-old pregnant woman with pyonephrotic kidney that we believe to be the first such case managed by transperitoneal laparoscopic nephrectomy. A review of the reported cases of laparoscopic nephrectomy for different indications and by different approaches during pregnancy is also presented.

Idiopathic Scrotal Calcinosis: A Non-Elucidated Pathogenesis and Its Surgical Treatment

Abdelhak KhalloukMohamed Jamal El FassiMoulay Hassan FarihOussama El YazamiMohamed Fadl TaziSoufiane Mellas

Scrotal calcinosis (SC) is a rare, benign entity defined as the presence of multiple calcified nodules within the scrotal skin. In most cases, there are no associated symptoms. We report the case of 27-year-old man with a massive SC. Treatment was surgical with complete excision of the affected part of the scrotum wall. Histopathologically, there was no epithelial lining around the calcified nodules and no cystic structure. Therefore, our case was considered idiopathic SC [Rev Urol. 2011;13(2):95-97 doi: 10.3909/riu0481] © 2011 MedReviews®, LLC
