Myofascial trigger points of the pelvic floor: associations with urological pain syndromes and treatment strategies including injection therapy.
Myofascial trigger points (MTrP), or muscle "contraction knots," of the pelvic floor may be identified in as many as 85 % of patients suffering from urological, colorectal and gynecological pelvic pain syndromes; and can be responsible for some, if not all, symptoms related to these syndromes. Identification and conservative treatment of MTrPs in these populations has often been associated with impressive clinical improvements. In refractory cases, more "aggressive" therapy with varied trigger point needling techniques, including dry needling, anesthetic injections, or onabotulinumtoxinA injections, may be used, in combination with conservative therapies.

ReviewColorectal surgery and its impact on male sexual function.
The quality of functional outcome has become increasingly important in view of improvement in prognosis with colorectal cancer patients. Sexual dysfunction remains a common problem after colorectal cancer treatment, despite the good oncologic outcomes achieved by expert surgeons. Although radiotherapy and chemotherapy contribute, surgical nerve damage is the main cause of sexual dysfunction. ⋯ The concept of total mesorectal excision (TME) in rectal cancer treatment has led to a substantial improvement of autonomic nerve preservation. In addition, use of laparoscopy has allowed favorable results with regards to sexual function. The present paper describes the anatomy and pathophysiology of autonomic pelvic nerves, prevalence of sexual dysfunction, and the surgical technique of nerve preservation in order to maintain sexual function.

Botulinum toxin-A (BTX-A) is well established in the management of various aspects of lower urinary tract dysfunction (LUTD). One formulation, OnabotulinumtoxinA has recently been licensed in many parts of the world for use in neurogenic detrusor overactivity (NDO), and in the US for idiopathic overactive bladder (OAB), in patient's refractory to antimuscarinics. This review article looks at recent clinical publications that examine the use of BTX-A for the treatment of LUTD with a focus on OAB, detrusor overactivity (DO), benign prostatic hyperplasia (BPH) and Painful bladder syndrome / interstitial cystitis (PBS / IC). ⋯ Repeated injections in DO appear efficacious. Results from BPH studies are mixed, and the largest randomised study in this setting has shown significant improvements in a number of parameters for a variety of OnabotulinumtoxinA doses, but none of the doses were statistically better than placebo. Few studies have been conducted in PBS / IC and larger scale randomised placebo controlled trials are required to validate its use in this setting.

Review Comparative StudyProton beam radiation therapy for prostate cancer-is the hype (and the cost) justified?
Although in use for over 40 years, proton beam therapy for prostate cancer has only recently come under public scrutiny, due to its increased cost compared to other forms of treatment. While the last decade has seen a rapid accumulation of evidence to suggest that proton beam therapy is both safe and effective in this disease site, a rigorous comparison to other radiotherapy techniques has not yet been completed. In this review, we provide an in-depth look at the evidence both supporting and questioning proton beam therapy's future role in the treatment of prostate cancer, with emphasis on its history, physical properties, comparative clinical and cost effectiveness, advances in its delivery and future promise.

ReviewPractical use of the new American Urological Association adult urodynamics guidelines.
In 2012, the American Urological Association published guidelines on adult urodynamics. On the basis of a review of the available evidence, they established guideline recommendations for urodynamics in adults with stress urinary incontinence/pelvic organ prolapse, overactive bladder/urinary urgency incontinence/mixed urinary incontinence, neurogenic bladder, and lower urinary tract symptoms. This article reviews the practical use of these guidelines in a clinical practice.
