One of the most controversial aspects of hypospadias surgery is the election of an appropriate wound dressing. In fact, there may be as many different types of dressing as there are types of surgical repair. Here, we describe a new, simple method for hypospadias dressing in children that minimizes painful removal.

INTRODUCTION: Plasmacytoid urothelial carcinoma (PUC) is a high-grade variant of conventional urothelial cell carcinoma. This study is the first to describe the imaging findings of PUC, which are previously unreported, using clinical and histopathological correlation. METHODS: With internal review board approval, we identified 22 consecutive patients with PUC from 2007-2014. Clinical parameters, including age, gender, therapy, surgical margins, and long-term outcome, were recorded...

Traumatic urethral catheterization may result in a number of serious complications. A rare occurrence is the development of a urethral pseudoaneurysm. We report the case of a 13-year-old male who required placement of a Foley catheter for an orthopedic surgical procedure. The Foley was misplaced in the bulbourethra, resulting in the development of a bulbar artery pseudoaneurysm. Profuse bleeding via the urethra was noted after removal of the catheter, and the patient experienced severe intermittent hematuria during the postoperative period...

Hematospermia is a common complaint among patients seen in outpatient urology clinics. The differential diagnosis is broad and includes inflammatory, infectious, neoplastic, structural, systemic, and traumatic causes. The most common infectious causes are uropathogens and sexually transmitted infections. However, with increasing global travel, physicians must maintain a high clinical suspicion for pathogens not endemic to their region, including Echinococcus, Mycobacterium tuberculosis, and Schistosoma.1 We present a case of hematospermia in a traveler returning from Eastern Africa with exposure to Lake Malawi...

Granulomatosis with polyangiitis (GPA, formerly Wegener's granulomatosis) is a systemic necrotizing vasculitis of small- and medium-sized blood vessels, primarily affecting the upper and lower respiratory tracts, as well as the kidneys. Urogenital manifestations of GPA are exceedingly rare and usually respond well to systemic immunosuppressive therapy. Here, we present a case of a 36-year-old female presenting with acute urinary obstruction secondary to urethral GPA involvement in the immediate postpartum period...

Treatment of testicular cancer is dependent on the stage of disease at presentation. Stage 1 testicular cancer is treated with radical orchiectomy, followed by active surveillance, radiotherapy, or chemotherapy. Occasionally, unusual and unexpected postoperative changes can be seen on computed tomography (CT), and may raise concern for metastatic disease. Here, we present two cases of testicular cancer patients who developed retroperitoneal hematomas post-radical orchiectomy, one as a classical clinical presentation, and the other as an atypical radiological entity only...

While arteriovenous malformations (AVMs) are a common congenital or post-traumatic abnormality, male genital AVMs are rare and have been described in the scrotum or penis in pediatric patients.1,2 We describe a 34-year-old male presenting with recurrent spontaneous penile urethral bleeding found to have an AVM of the penile urethra. While angiography has traditionally been helpful, magnetic resonance imaging (MRI) can aid in the diagnosis and characterization of these lesions.3 Each case of male genital AVM provides a unique challenge to manage depending on the presenting complaint, as there are no guidelines to direct treatment...

INTRODUCTION: Nitric oxide (NO) plays an important role in the ischemia and reperfusion process. In this study, we aimed to examine the effect of L-arginine, tadalafil, and their combination for prevention of the ischemia reperfusion injury after testis torsion in rats. METHODS: A total of 40 adult, male Sprague-Dawley rats were allocated into five groups. Three hours of left testicular torsion was performed in each group, excluding the control group. While the ischemia reperfusion (I/R) group had no treatment, I/R + Arg group received L-arginine, I/R + Td group received tadalafil and I/R + Arg + Td group received tadalafil and L-arginine 30 minutes before the detorsion...

INTRODUCTION: The developments in hypospadias surgical techniques and materials are intended to improve surgery outcomes and patient comfort. The aim of this study is to determine the effect of the Zaontz urethral stent (ZUS) (Cook Medical) on patient comfort and surgical success rates in children undergoing hypospadias surgery. METHODS: A feeding tube was used to repair 46 cases of primary distal hypospadias, and ZUS (6F, 8F, and 10F in diameter) was used to repair to 31 cases of primary distal hypospadias between December 2009 and June 2011 in our clinic...

INTRODUCTION: We aimed to introduce the diagnostic value of diffusion-weighted (DWI) magnetic resonance imaging (MRI) for distinguishing benign and malignant renal cystic masses. METHODS: Abdominal DWI-MRIs of patients with Bosniak categories 2F, 3, and 4 cystic renal masses were evaluated retrospectively. Cystic masses were assigned as benign or malignant according to histopathological or followup MRI findings and compared with apparent diffusion coefficient (ADC) values...

This clinical guideline focuses on: 1) the use of multiparametric magnetic resonance imaging (mpMRI) in diagnosing clinically significant prostate cancer (CSPC) in patients with an elevated risk of CSPC and who are biopsy-naïve; and 2) the use of mpMRI in diagnosing CSPC in patients with a persistently elevated risk of having CSPC and who have a negative transrectal ultrasound (TRUS)-guided systematic biopsy. The methods of the Practice Guideline Development Cycle were used. MEDLINE, EMBASE, the Cochrane Library (1997‒April 2014), main guideline websites, and relevant annual meeting abstracts (2011‒2014) were searched...

Daniel Y C Heng
The introduction of targeted therapies over the past 10 years revolutionized the treatment of metastatic renal cell carcinoma (mRCC). The next 10 years hold promise for even greater expansion of the therapeutic armamentarium for mRCC. A number of recently completed and ongoing trials have explored the use of antivascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitors (TKIs) and mammalian target of rapamycin (mTOR) inhibitors in the adjuvant setting, the use of predictive biomarkers to guide personalized medicine, as well as new systemic treatments and combination therapies for mRCC...

REVIEW
Georg A Bjarnason
The recommended starting dose and schedule for sunitinib is 50 mg daily for 28 days, followed by a 14-day break with significant dose reductions to 37.5 mg (75% of starting dose), and then 25 mg (50% of starting dose) on the same schedule (four/two schedule). There are several reasons why these dose and scheduling recommendations may not be optimal for most patients, as outlined below.

REVIEW
Christian Kollmannsberger
With the proliferation of treatment options for the management of metastatic renal cell carcinoma (mRCC) over the past decade, predictive markers of response to therapy are becoming increasingly important. Sunitinib is commonly used in the first-line treatment of mRCC. Common mechanism-based adverse events, including hypertension, hypothyroidism, hand-foot syndrome, and neutropenia, have been explored as potential biomarkers of the clinical efficacy of sunitinib in mRCC and are reviewed in this article.
