AIMS: To report on the long-term outcomes of hydraulic artificial urethral sphincter (HAUS) placement for the correction of urethral sphincter mechanism incompetence (USMI) in New Zealand dogs.
METHODS: Retrospective data were obtained from cases of dogs which had a HAUS placed after failed medical and/or surgical management of USMI between August 2012 and November 2016. Owner assessment of urinary incontinence was evaluated by an online survey in May 2017 using a visual analogue scale (0 being normal, 100 being severely affected) for the frequency, volume and severity of any straining to urinate, immediately prior to the placement of the HAUS and at the time of the survey. The number of days between surgery and the completion of survey were recorded.
RESULTS: Seven females and two male dogs, which were all desexed except for one female, were eligible for inclusion in the study. The period of follow-up following HAUS placement ranged from 206–1,685 days. Following HAUS placement, frequency and volume of urinary incontinence decreased for six dogs and were practically unchanged for three dogs. The median frequency score decreased from 70 to 13 and the volume score decreased from 73 to 12. There was no consistent change in the perceived degree of straining to urinate. Complications occurred in three dogs; one required repositioning of a dislodged injection port, one required management for haematuria and a hypoplastic bladder, and one required surgical removal of fibrous tissue around the HAUS cuff.
CONCLUSIONS AND CLINICAL RELEVENCE: HAUS placement was an effective method for the treatment of persistent USMI in most dogs and provided good clinical results based on owner assessment. The technique was associated with few complications and allowed successful long-term control of urinary incontinence without the need for medical management. 相似文献
There is an increasing demand for air-dry performance of fluorocarbon finished materials. Thus, surface modifications of wool
fabrics were evaluated. Untreated, gaseous fluorinated, Chlorine/Hercosett processed 100 % wool fabrics were treated with
different fluorochemicals and their liquid repellency after washing, and dry cleaning were evaluated. The results indicated
that Chlorine-Hercosett treated samples, wool with a positive charge, after few washing cycles, showed better air dry performance
with higher level of repellent properties. In addition, the comparison of the wool surface modifications treatment with different
applied fluorochemicals, with different commercial formulations, illustrated that the fluorocarbon chain re-orientation and
fastness properties are more affected by the nature of the wool surface while the used fluorocarbons showed more or less similar
behaviours. In general, the fluorination increases fabric stiffness with lower fabric formability. The surface interface was
effectively probed by X-ray Photoelectron Spectroscopy, XPS, which enabled the characterisation of the loss of surface lipids,
the nature of the fibre oxidation and the deposition of fluoropolymers. 相似文献
