Developing alternative devices to the long-term urinary catheter for draining urine from the bladder

The self-retaining urinary catheter is used for long-term drainage of urine from the bladder only as a last resort because of serious associated complications, yet it remains a routine method for managing older and disabled patients with loss of bladder control. Blockage of the catheter from calcified deposits within its lumen is a common occurrence, obstructing the passage of urine and causing an urgent, unpredictable problem for patients, carers and the nursing staff. The need for further research on the subject has been recognized for many years. The SuPort Project aimed to develop an alternative suprapubic urine collection system. This report outlines the approach adopted towards the design and selection of the novel device, the production problems that ensued and the small clinical trial of a modified prototype

The thermo-expandable metallic stent for managing benign prostatic hyperplasia: a systematic review.

OBJECTIVES: To systematically review published reports of the safety, effectiveness and durability of a self-expanding metallic prostatic stent (Memokath, Engineers & Doctors A/S Ltd., Denmark) in patients with benign prostatic hyperplasia (BPH) who are unfit for surgery. METHODS: We systematically searched the Medline and Embase databases from 1992. The reference lists of included studies and the bibliographies of review articles were also searched. We contacted the manufacturer of Memokath for additional information. The primary outcomes were treatment failure (stent removal, replacement or repositioning) and urological symptom scores. Secondary outcomes were urodynamic indices and minor complications. Two reviewers independently assessed the methodological quality of the studies and extracted data. Data were synthesized using narrative techniques. RESULTS: In all, 14 case series described the use of the Memokath stent in 839 men with BPH. All patients were at high operative risk. Most studies were of poor quality with an inadequate follow-up. Treatment failure rates were 0-48% but the duration of follow-up was often unclear. Five studies reported International Prostate Symptom Scores and found reductions of 11-19 points after stent insertion. All seven studies that reported on maximum urinary flow rates found that these increased, and the four that described residual urine volumes found that these decreased. Minor complications were inconsistently reported. CONCLUSIONS: The Memokath stent can provide an effective treatment for BPH in men at high operative risk; it also appears to be safe, but inadequate follow-up does not allow firm conclusions on stent durability

Living with a long-term urinary catheter: Older people's experiences

Title. Living with a long-term urinary catheter: older people's experiences. Aim. This paper is a report of a study of the experiences of older people living with a long-term urinary catheter and the development of a substantive theory grounded in their realities. Background. Understanding the user perspective is a prerequisite for involving older people in a collaborative relationship with healthcare professionals which is built around their needs and wishes. Older people's views and experiences of the complexity of living with a long-term catheter have not been widely researched. An enhanced understanding of catheter users' perspectives and an awareness of their needs can be used to improve care. Method. A grounded theory approach was adopted and 20 in-depth interviews were carried out in England in 2005 and 2006 with 13 older people living at home with long-term urinary catheters. Findings. The core category 'all about acceptance' described older people's adjustment to living with a long-term urinary catheter; the two categories 'at ease' and 'uneasy' reflect the extremes of contentment experienced. Three interlinking categories of 'trying to understand', 'judging catheter performance' and 'being aware of the catheter' shaped older people's relationships with their catheters and this was mediated by their 'interaction with others'. The consequences for older people fluctuated along a continuum from 'engaging actively' to experiencing 'downbeat sentiments'. Conclusion. To assist older people to adjust to living with a catheter, healthcare professionals must be sensitive to their life situations and individual needs rather than focusing predominantly on catheter performance and complications. © 2008 Blackwell Publishing Ltd
