This passive “”optical”" structure allows either the generation of a subwavelength confinement of the longitudinal electric field (polarized along the wire antenna) or, due to reciprocity, the collection of the longitudinal component of the electric field (along the wire antenna) with subwavelength resolution. The emission and collection properties of the proposed antenna have been demonstrated experimentally using a preliminary realization
designed to work at 0.1 THz. Experimental results are well supported by calculations. (C) 2009 American Institute of Physics. [doi: 10.1063/1.3236665]“
“This study aims to analyze comparatively the efficacy and safety of synthetic transobturatory and aponeurotic retropubic slings, in the treatment of selleckchem stress urinary incontinence (SUI) in women.
Patients were separated in a randomized way. Twenty-one patients were submitted to the operatory correction by the transobturatory sling technique, whereas 20 patients were operated by the retropubic sling technique. All patients were submitted to complete physical exam and urodynamic test. The “”T”" test and the Mann-Whitney U test were applied to establish comparisons between the two groups. Patients were followed-up Selleck PFTα for 12 months.
Healing rate was 90.5% (19/21) and 95% (19/20), respectively after 12 months. The transobturatory group presented lesser complications rate
than the retropubic group.
The transobturatory and the aponeurotic slings techniques were equally effective for the treatment of SUI. The transobturatory sling has shown fewer complications and lesser surgical time than the aponeurotic sling technique.”
“The levator ani muscle is generally thought to play a role in urinary continence, with incontinence assumed to be due to abnormal muscle function or morphology. This study examined whether avulsion of the puborectalis muscle is associated with symptoms or signs of bladder dysfunction.
In
a retrospective observational study, we reviewed the records of 425 women who had attended a urogynecological unit for independent flowmetry, multichannel urodynamic testing, and 4D pelvic floor ultrasound.
Mean age was 55 years (range, 17-87 years). Of 420 women with complete datasets, 104 (25%) were diagnosed with a puborectalis muscle avulsion. Z IETD FMK These women were less likely to suffer from stress urinary incontinence (SUI; P < 0.001) and urodynamic stress incontinence (USI; P = 0.065) and more likely to present with symptoms of prolapse (P < 0.001) and show signs of voiding dysfunction (P = 0.005). The negative association between avulsion and SUI persisted in multivariate models.
Puborectalis muscle trauma is not associated with an increased risk of SUI or USI in a urogynecological population, even when controlling for symptoms or signs of prolapse and previous surgery.”
