Chronic Indwelling Foley and Catheter Associated Trauma (CIF-CAT) Study

2019-01-09 10:54:20 | BioPortfolio


To determine whether an indwelling low profile Kohli Atraumatic Catheter causes less macro-morphologic inflammation and edema to the bladder mucosa than a traditional indwelling Foley catheter as assess by computerized image analysis.


The Kohli Atraumatic Catheter similarly aims to reduce bladder mucosal trauma with its low profile pancake shaped balloon versus the ovoid balloon of a traditional Foley catheter. The Kohli Atraumatic Catheter has a short, opened-ended tip that minimally protrudes through a patented low-profile donut-shaped balloon. The combination of the low profile and reduced tip length prevents the catheter from contacting the bladder walls and thereby minimize disruption of the bladder surface mucus layer and trauma to the urothelium - theoretically reducing the chance of bacterial invasion. A trial in which sheep were randomized to a traditional indwelling Foley catheter or a prototype Kohli Atraumatic Catheter demonstrated a dramatic reduction in both bladder wall trauma and edema. The ulcerated area dropped from 7.2% to 1.8% (75%) and the edema from 26.9% to 13.0% (52%).

Statistical Analysis To compare the effects of 2 catheter types, data will be analyzed using the general linear models tools from SAS/STAT software and presented as means ± standard error of the mean. The model will include 2 catheter types, inflamed vs non-inflamed areas, and their interactions.

Medical and Biotech [MESH] Definitions

Endoscopic examination, therapy or surgery of the urinary bladder.

A HERNIA-like condition in which the weakened pelvic muscles cause the URINARY BLADDER to drop from its normal position. Fallen urinary bladder is more common in females with the bladder dropping into the VAGINA and less common in males with the bladder dropping into the SCROTUM.

Involuntary discharge of URINE as a result of physical activities that increase abdominal pressure on the URINARY BLADDER without detrusor contraction or overdistended bladder. The subtypes are classified by the degree of leakage, descent and opening of the bladder neck and URETHRA without bladder contraction, and sphincter deficiency.

An abnormal passage in the URINARY BLADDER or between the bladder and any surrounding organ.

Multinucleated cells (fused macrophages) seen in granulomatous inflammations such as tuberculosis, syphilis, sarcoidosis, and deep fungal infections. They resemble foreign-body giant cells (GIANT CELLS, FOREIGN BODY) but Langhans giant cells contain less chromatin and their nuclei are arranged peripherally in a horseshoe-shaped pattern. Langhans giant cells occur frequently in delayed hypersensitivity.
