Erosion of urethra in female patients with spinal cord injury

Urine-drainage leg bags: an overview

This article looks at leg bags from the perspective of the clinical guidance available, published research, review papers, the diverse nature of products available, and their use with catheters, sheaths or urinals. The part that leg bags play in catheter-associated urinary tract infection control is addressed. Other aspects of catheter safety are discussed, including the avoidance of catheter traction. Variations in leg-bag structure including bag size, inlet tubing, tap, connector and backing, along with the reasons for selecting a particular leg bag are considered, along with the choice of either leg-bag straps or sleeves. The article concludes that, as a result of the variation of leg bags available, patients may require assistance and support from health professionals in finding the right leg bag for them.

Catheter lubrication and fixation: interventions

This article looks at the indications for catheterisation, the anatomy of the urethra, the importance of asepsis and the rationale for the use of urethral lubrication for catheter insertion. The variations of lubrication available are discussed, including the use of products containing lidocaine and chlorhexidine. It then considers the problems caused by traction to the catheter and discusses the securement devices available for preventing tissue damage at the bladder neck, within the urethra and also at the meatus. The variation of devices is examined along with the potential problems associated with their use. Finally, it discusses the importance of clinicians being knowledgeable about the problems looked at and how to resolve them.

Biofilm and other causes of pain in catheterization

This article looks at the anatomy of the bladder and how sensations, including pain, are transmitted to the brain. The use of urinary catheters is discussed and initially, the development of biofilm is addressed, from its cause, structure and effect, to how it can be treated. Many of the problems arising from biofilm and the resulting encrustation, can lead to pain, and the causes of this are discussed. Other problems which can cause patients to experience pain are also considered, and where there are possible solutions, these have been put forward. However, even when good practice is carried out, there will still be problems encountered, and further research is needed.

[Specific features of urethral diseases in spinal cord injury patients]

This article discusses all of the urethral diseases observed in patients with neurogenic bladder. The frequency of these disorders has decreased considerably with progress in intermittent catheterization and bladder retraining. However, urologists may occasionally be required to manage an urethral diverticulum, or an ulcer of the urethra over an indwelling catheter and must be familiar with the specific features in this setting.
