Frequency of urinary tract infection was determined in 82 patients with urolithiasis and in 40 patients with an indwelling Catheter. Significantly high proportion of adult patients with renal and vesical calculi were infected while children with bladder stones had high proportion of sterile urine. Indwelling catheter was associated with a high rate of urinary infection (JPMA 31:254,1981).

We describe a novel infection-responsive coating for urinary catheters that provides a clear visual early warning of Proteus mirabilis infection and subsequent blockage. The crystalline biofilms of P. mirabilis can cause serious complications for patients undergoing long-term bladder catheterisation. Healthy urine is around pH 6, bacterial urease increases urine pH leading to the precipitation ...

The aim of this study was to analyse the outcome of trial off catheter for patients who were admitted to the Department of Urology, Singapore General Hospital (SGH) for acute retention of urine (ARU) due to benign prostatic hypertrophy (BPH). From 1 June to 15 October 1997, 150 patients were admitted for ARU. Seventy-one patients were excluded from our study due to our exclusion criteria such a...

Colonization of urinary catheters by bacteria which produce urease leads to an increase in urine pH, followed by deposition of the minerals struvite and hydroxyapatite. Adhesion of these encrusting deposits can be reduced, but not prevented, by using catheters with a smooth surface finish. Chemical methods for preventing encrustation are not completely satisfactory. A better way of preventing e...

BACKGROUND Prostate traction is one way to control post-prostatectomy bleeding. The most popular method involves traction with a catheter fixed to the thigh with adhesive bands. However, this method has its own drawbacks. OBJECTIVES We aimed to simplify this traction procedure and to overcome its disadvantages. PATIENTS AND METHODS From 2007 - 2015, a new method was used to control post-pro...

BACKGROUND Retrograde ureteropyelography plays a vital role in imaging of the upper tract, particularly in aiding the diagnosis of upper tract urothelial cancers.1 Retrograde studies in theatre are often of inferior quality compared with those performed in the radiology department. Retrograde ureteric catheter placement in theatre is therefore followed by formal retrograde studies in the radiol...

candida glabrata was thought to be a primarily non-pathogenic organism. however, with the ever-increasing population of immunocompromised individuals, it is considered to be an opportunistic pathogen. patients with spinal cord injuries often using a long-term urinary catheter and are high risk for urinary tract infections. this case report describes a patient with spinal cord injury (thoracic r...

Background. Catheter associated urinary tract infections (CAUTIs) are the most frequent healthcare-associated infection (HAI). Intensive care unit (ICU) CAUTIs identified using the National Healthcare Safety Network (NHSN) definition are publicly reported and are considered as a quality measure. However, clinicians are often challenged with differentiating CAUTI from asymptomatic bacteriuria. W...

OBJECTIVE To evaluate the management of patients with long-term (>1 month) indwelling catheter by general practitioners (GP). PATIENTS AND METHODS A self-questionnaire was sent to 603 regional GP, between March and May 2010. It was composed of 12 multiple-choice questions and one open question, about management of their patients with indwelling catheter. RESULTS Two hundred and twenty-eight...

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...
