Quality-of-life outcomes from the Prostate Adenocarcinoma: TransCutaneous Hormones (PATCH) trial evaluating luteinising hormone-releasing hormone agonists versus transdermal oestradiol for androgen suppression in advanced prostate cancer

To compare quality‐of‐life (QoL) outcomes at 6 months between men with advanced prostate cancer receiving either transdermal oestradiol (tE2) or luteinising hormone‐releasing hormone agonists (LHRHa) for androgen‐deprivation therapy (ADT).

Fournier's Gangrene Associated with Intradermal Injection of Cocaine

INTRODUCTION Cocaine abuse is associated with a number of medical complications, most notably arrhythmias, myocardial infarction, and cerebral hemorrhages. The injection of cocaine in the penis has been predominantly recorded into the corpus cavernosae and is associated with priapism. AIM Here we describe the injection of subcutaneous cocaine within the penile shaft skin producing ischemic necrosis and Fourniers gangrene. MAIN OUTCOME MEASURES We sought to highlight the effects of cocaine use within the penis and emphasize the different effects that may ensue. METHODS We reviewed a recent clinical case and conducted a literature review on the use of cocaine within the penis. RESULTS The use of cocaine has been reported previously within the literature and is mainly limited to case reports. Cocaine use within the corpora and the subcutaneous tissues produces significantly different consequences ranging from priapism to Fourniers gangrene. CONCLUSIONS The case illustrates the growing use of cocaine and other illicit drugs and emphasizes the importance of this issue to all clinicians.

Lower urinary tract symptoms in an older man

#### What you need to know A 65 year old man comes to see you with problems urinating. He feels the need to pass urine often, and it takes a long time to void when he does. Lower urinary tract symptoms in men are common and increase with age.1 There is an estimated prevalence of >50% in men over 50 years old.2 Between the ages of 40 and 79 years, the prevalence of moderate to severe symptoms increases by 9.8% per decade.3 There is also a strong association of lower urinary tract symptoms with metabolic syndrome (including obesity, diabetes, and hypertension).45 Lower urinary tract symptoms in men are most commonly due to benign prostatic enlargement, which can cause bladder outflow obstruction.67 However, not all men with benign prostatic enlargement will have bothersome symptoms.6 Lower urinary tract symptoms can interfere with general wellbeing, sleep, and sexual activity. They are an independent risk factor for sexual dysfunction in men over the age of 50 years.2 Some patients who seek medical attention may be …

Active surveillance for low-risk prostate cancer

Overtreatment of prostate cancer has become evident as studies comparing radical prostatectomy vs watchful waiting have shown that radical treatment benefits only a proportion of patients. Active surveillance was introduced as a management option for prostate cancer at low-risk of progression with the aim to closely observe for disease progression or change of tumour characteristics and offer active treatment if and when necessary. Active surveillance has been reserved for patients with Gleason 6 localised disease and low PSA; however, selection criteria may be widened as intermediate-term outcomes demonstrate excellent safety, efficacy and patient acceptance.

Evaluation of the pressure leak test in increasing the lifespan of flexible ureteroscopes

Flexible ureteroscopes are expensive and delicate instruments that are integral in the offering of a minimally invasive technique of diagnosis and treatment of urolithiasis. Published literature has identified the importance of early damage recognition in preventing frequent use of the scope that would lead to further damage and high repair and replacement costs. Our study was designed to examine the outcome of the pressure leak test on the condition of flexible ureteroscopes after every use and analysing the damage and costs of maintenance.

Prostate cancer with metastases to the kidney: a rare manifestation of a common disease

A 66-year-old Caucasian man with a background of prostate cancer presented with a progressive history of nausea, reduced appetite, shortness of breath and a distended abdomen. Radiological imaging revealed a left-sided renal mass and gross ascites suggestive of metastatic renal cell carcinoma (RCC). Subsequent histological examination and immunostaining of renal mass biopsy revealed features characteristic of metastatic moderately differentiated to a focally poorly differentiated, large duct type of prostatic adenocarcinoma.

Bipolar Transurethral Resection of Prostate: Current Status in the Management of Bladder Outflow Obstruction

Monopolar transurethral resection of prostate has been the preferred surgical treatment of benign prostatic hyperplasia. Even in modern series there are significant risks such as haemorrhage requiring transfusion and TUR syndrome, although their incidence is lower than previously. Over the last decade or so newer technologies have emerged that have proven to be at least equivalent to monopolar TURP. Bipolar transurethral resection of the prostate in normal saline is a potentially safer option to monopolar resection but with equivalent efficacy in the medium term. This is supported by 2 recent meta-analyses. This review describes the technology, efficacy and safety profile of bipolar transurethral resection of the prostate.

A review of the contemporary management of upper urinary tract urothelial carcinoma

Upper tract urothelial carcinoma (UTUC) is relatively rare and accounts for approximately 5% of all urothelial carcinomas. The estimated annual incidence of UTUC in Western countries is about two new cases per 100,000 inhabitants. The management of patients with upper tract urothelial carcinomas has changed significantly over the last decade with improved diagnostic techniques and treatment options. The gold-standard treatment used to be open radical nephroureterectomy with removal of the ipsilateral bladder cuff. The use of minimally invasive techniques for the diagnosis and management of upper urinary tract urothelial carcinoma is however expanding and has led to a paradigm shift in treatment strategies of upper tract urothelial carcinomas. In this article, we review the current diagnostic modalities and various endoscopic techniques being currently used in the management of this relatively rare tumour.

Spontaneous rupture of a renal artery pseudoaneurysm with no precipitating risk factor

Renal artery pseudoaneurysm is a rare complication following renal interventional procedures or, although it may be spontaneous as described in this case. Clinicians should have a low threshold for early computer tomography (CT) imaging in cases of diagnostic uncertainty.

Radiofrequency-induced Thermo-chemotherapy Effect Versus a Second Course of Bacillus Calmette-Guérin or Institutional Standard in Patients with Recurrence of Non–muscle-invasive Bladder Cancer Following Induction or Maintenance Bacillus Calmette-Guérin Therapy (HYMN): A Phase III, Open-label, Randomised Controlled Trial

BACKGROUND There is no effective intravesical second-line therapy for non-muscle-invasive bladder cancer (NMIBC) when bacillus Calmette-Guérin (BCG) fails. OBJECTIVE To compare disease-free survival time (DFS) between radiofrequency-induced thermo-chemotherapy effect (RITE) and institutional standard second-line therapy (control) in NMIBC patients with recurrence following induction/maintenance BCG. DESIGN, SETTINGS, AND PARTICIPANTS Open-label, phase III randomised controlled trial accrued across 14 centres between May 2010 and July 2013 (HYMN [ClinicalTrials.gov: NCT01094964]). INTERVENTION Patients were randomly assigned (1:1) to RITE (60min, 40mg mitomycin-C, 42±2°C) or control following stratification for carcinoma in situ (CIS) status (present/absent), therapy history (failure of previous induction/maintenance BCG), and treatment centre. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Primary outcome measures were DFS and complete response (CR) at 3 mo for the CIS at randomisation subgroup. Analysis was based on intention-to-treat. RESULTS AND LIMITATIONS A total of 104 patients were randomised (48 RITE: 56 control). Median follow-up for the 31 patients without a DFS event was 36 mo. There was no significant difference in DFS between treatment arms (hazard ratio [HR] 1.33, 95% confidence interval [CI] 0.84-2.10, p=0.23) or in 3-mo CR rate in CIS patients (n=71; RITE: 30% vs control: 47%, p=0.15). There was no significant difference in DFS between treatment arms in non-CIS patients (n=33; RITE: 53% vs control: 24% at 24 mo, HR 0.50, 95% CI 0.22-1.17, p=0.11). DFS was significantly lower in RITE than in control in CIS with/without papillary patients (n=71; HR 2.06, 95% CI 1.17-3.62, p=0.01; treatment-subgroup interaction p=0.007). Disease progression was observed in four patients in each treatment arm. Adverse events and health-related quality of life between treatment arms were comparable. CONCLUSIONS DFS was similar between RITE and control. RITE may be a second-line therapy for non-CIS recurrence following BCG failure; however, confirmatory trials are needed. RITE patients with CIS with/without papillary had lower DFS than control. HYMN highlights the importance of the control arm when evaluating novel therapies. PATIENT SUMMARY This study did not show a difference in bladder cancer outcomes between microwave-heated chemotherapy and standard of care treatment. Papillary bladder lesions may benefit from microwave-heated chemotherapy treatment; however, more research is needed. Both treatments are similarly well tolerated.
