Overactive bladder is a common and bothersome condition. Antimuscarinic agents, as a class, are the cornerstone of medical treatment of overactive bladder. They offer significant improvements in symptoms and patients' quality of life. Antimuscarinics are generally well tolerated with mild and predictable side effects. Available antimuscarinics have small,(More)
PURPOSE OF REVIEW To summarize data concerning the medical treatment of men with overactive bladder symptoms published in peer-reviewed journals between January 2012 and March 2013. RECENT FINDINGS Results of large, randomized trials of solifenacin in combination with tamsulosin in men with lower urinary tract symptoms, including voiding and storage ones,(More)
OBJECTIVE To investigate the impact of daily sildenafil on levels of soluble molecular markers of endothelial function in men with erectile dysfunction. METHODS Patients aged >18 years with erectile dysfunction of vascular etiology for >6 months, either alone or in combination with disease states strongly associated with endothelial dysfunction such as(More)
Sildenafil was the first orally administered phosphodiesterase-5 inhibitor approved for the treatment of erectile dysfunction. Its successful introduction into clinical practice was soon followed by the launch of two other phosphodiesterase-5 inhibitors: vardenafil and tadalafil. The plethora of choices made the question "which PDE-5 inhibitor?" relevant(More)
INTRODUCTION Locally advanced or metastatic renal cell carcinoma (RCC) is notoriously chemo- and radioresistant, leaving immunotherapy as the only treatment option. In recent years, targeted therapies have offered significant increases in progression-free survival (PFS). Despite this, the majority of patients soon develops resistant disease and finally(More)
BACKGROUND Lower urinary tract symptoms (LUTS) are prevalent in ageing men and commonly coexist with erectile dysfunction. Preclinical data on the involvement of the nitric oxide/cyclic guanosine monophosphate/phosphodiesterase pathway in the regulation of lower urinary tract smooth muscle activity have been available for several years. Phosphodiesterase 5(More)
BACKGROUND Storage lower urinary tract symptoms (LUTS) or overactive bladder (OAB) often coexist with voiding symptoms in patients with benign prostatic obstruction (BPO). Anticholinergic medications to treat storage LUTS are often withheld in such patients for fear of significantly increasing post-void residual urine volumes or provoking acute urinary(More)
OBJECTIVE To test the hypothesis that the ultrasound-estimated bladder weight (UEBW) will correlate with the urodynamic diagnoses in women with lower urinary tract symptoms, in particular, detrusor underactivity and bladder outflow obstruction. Ultrasonography has been increasingly used in the assessment of lower urinary tract conditions. METHODS Adult(More)
Abdominal sacrocolpopexy (ASC) is considered the gold standard for vaginal vault prolapse (VVP) repair. Our aim was to evaluate the long-term durability of its anatomic and functional results. This was a prospective series of women undergoing ASC for symptomatic VVP stage III or IV according to the Pelvic Organ Prolapse Quantification (POP-Q) system. All(More)
Obstructive sleep apnoea, characterised by repetitive occlusion of the upper airway during sleep, is recognised as a risk or even an aetiological factor for erectile dysfunction. On the other hand, sleep-disordered breathing has been reported by many patients with erectile dysfunction. Sildenafil, a very commonly used erectile dysfunction treatment, could,(More)
