Urinary catheters: history, current status, adverse events and research agenda.

For more than 3500 years, urinary catheters have been used to drain the bladder when it fails to empty. For people with impaired bladder function and for whom the method is feasible, clean intermittent self-catheterization is the optimal procedure. For those who require an indwelling catheter, whether short- or long-term, the self-retaining Foley catheter is invariably used, as it has been since its introduction nearly 80 years ago, despite the fact that this catheter can cause bacterial colonization, recurrent and chronic infections, bladder stones and septicaemia, damage to the kidneys, the bladder and the urethra, and contribute to the development of antibiotic resistance. In terms of medical, social and economic resources, the burden of urinary retention and incontinence, aggravated by the use of the Foley catheter, is huge. In the UK, the harm resulting from the use of the Foley catheter costs the National Health Service between £1.0-2.5 billion and accounts for ∼2100 deaths per year. Therefore, there is an urgent need for the development of an alternative indwelling catheter system. The research agenda is for the new catheter to be easy and safe to insert, either urethrally or suprapubically, to be retained reliably in the bladder and to be withdrawn easily and safely when necessary, to mimic natural physiology by filling at low pressure and emptying completely without damage to the bladder, and to have control mechanisms appropriate for all users.

[Historical comments on urinary bladder catheterisation: an urological success story]. / Historische Anmerkungenzum Harnblasenkatheterismus - eine urologische Erfolgsgeschichte.

The first sounds and tubes were made of gold, bronze and tin or instruments made of reed, straw or rolled palm leaves. Over the course of the centuries the material as well as the design evolved because of the better knowledge of the anatomy of the human body. Especially French and German pioneers of the 19th and 20th century with their new innovations led to the progress of the catheter. From the search of the right material, to the innovation of and appropriate fixation mechanism in the bladder. Only by continous promotion of the inventions over the turn of the time a perfect instrument made of the perfect material could evolve.

Management of the bladder in traumatic injuries of the spinal cord during the First World War and its implications for the current practice of urology.

What's known on the subject? and What does the study add? Prior to the First World War, traumatic injuries to the spinal cord rapidly led to death from severe infections of the bladder. During the Second World War, Ludwig Guttmann resurrected the use of intermittent catheterisation at Stoke Mandeville Hospital, by meticulous attention to detail and was so successful, that this method was introduced into general urological practice. Historical review of the management of the bladder in patients with spinal injuries. Spinal injury patients--literature review--personal experience at Stoke Mandeville Hospital. Review of the different methods of catheterisation from the 19th century to today. Methods learned from the management of the bladder of spinal injuries patients were adopted into mainstream urology.

Two centuries of cystoscopy: the development of imaging, instrumentation and synergistic technologies.

The cystoscope used today is the product of centuries of development. The desire to view the cavities of the body was first described several centuries ago. The earliest true prototype was Bozinni's 1805 urethral viewing tube, on which many others were based. These primitive instruments were challenging to use for the operator, uncomfortable for the patient, and dangerous for both. Patient positioning was based on the method of bladder distension and the goal of the operation, rather than comfort. Images visualized by early models were inverted and backwards, and required the operator to be skilled in correcting this image. Reflected candlelight was used for illumination, and objects appeared small and distant. With the advent of lenses, prisms and the incandescent light, cystoscopy advanced to Nitze's prototype, a forerunner of the current cystoscope. Once the image quality was improved, instrumentation through the cystoscope was introduced, broadening the scope of urology, from the management of venereal disease to a premier surgical speciality. Finally, the invention of fibre optics and digital imaging provided the cystoscope used by urologists worldwide, giving unparalleled image quality, allowing for educational opportunities and a quality of patient care unimaginable to the early pioneers. An understanding of this past brings not only an appreciation of the technology currently available, but also a glimpse into what the cystoscope has the potential to become. From this past, it is clear that today's cystoscope is merely a forerunner of that which the future will bring.

[A case of vesicourethral foreign body for catheterization by scallion: historical discussion about urethral catheter].

A 62 year old man with a spinal injury was referred to our hospital for removal of an impacted scallion that he had inserted into his urethra as a form of self-catheterization. We first attempted unsuccessfully to remove the scallion using a Kocher clamp. We then performed transurethral removal of the foreign body, that turned out to be a scallion 30 cm in length. In this paper, we present a case report of self-catheterization using scallions, as well as a history of the urethral catheter.

The Foley catheter.

In the third of our biographical series tracing the origination of some of today's most commonly used surgical instruments and the people behind them, Professor Ellis explores the history of the catheter, and the breakthrough design by American urologist Frederick Foley.

The catheter and its use from Hippocrates to Galen.

PURPOSE: We comprehensively reviewed the history and use of the bladder catheter in Western medicine from 500 BC to 200 AD. MATERIALS AND METHODS: Greek and Latin texts were key word searched to identify descriptions of contemporary instruments and their uses. RESULTS: The catheter and its use were mentioned by about 10 ancient authors in more than a total of 20 texts dating to the end of the second century AD. The authors include Hippocrates, Celsus, Soranus, Rufus, Aretaeus and Galen. They described the use of the instrument in reference to contemporary anatomy and physiology, and indications and contraindications in regard to certain conditions, such as urinary retention, bladder stones and intravesical blood clots. Technical details and particularities of use were also reviewed, as were pharmacological considerations and underlying physical principles. CONCLUSIONS: Knowledge of the urinary catheter, and its usefulness and risks in ancient medicine can be dated from the 5th century BC. Our study of European texts documents its broad use. Because catheterization was perceived as a practical measure, it generated little scientific controversy.

The catheter and its use in late antiquity and the early middle ages.

PURPOSE: Based on Greek and Latin sources the use of the urinary catheter in Western medicine between 200 and 1000 CE was reviewed. MATERIALS AND METHODS: Computerized databank searches permitted the identification and analysis of ancient and early medieval texts that include material on the catheter. RESULTS: Ten medical authors mentioned the catheter and its use. In the Byzantine world they include the encyclopedists Oribasius, Aetius and Paul of Aegina. The best known Latin author is Caelius Aurelianus. These writers often put together summaries of earlier works. Innovation or independent research was not easily found at a time during which neither anatomical autopsy nor experimentation was widely practiced. CONCLUSIONS: Old texts contain numerous instructions on how to skillfully use the catheter. As a technical achievement, it was independent of philosophical trends. Its primary indications, namely urinary retention, bladder stones and the administration of cures, changed little with time. As one of the oldest and most important instruments at the disposal of physicians, the history of the catheter should be known to every urologist.
