A coudé catheter, including Tiemann's catheter, is designed with a curved tip that makes it easier to pass through the curvature of the prostatic urethra. [2] A hematuria catheter is a type of Foley catheter used for Post-TURP hemostasis. This is useful following endoscopic surgical procedures, or in the case of gross hematuria.
When a Foley catheter becomes clogged, it must be flushed or replaced. There is currently not enough adequate evidence to conclude whether washouts are beneficial or harmful. [13] There are several risks in using a Foley catheter (or catheters generally), including: The balloon can break as the healthcare provider inserts the catheter.
The patient was given the following medication regimen: oral cefuroxime, then changed to ceftriaxone IV and gentamicin IV, and oral glycerol for constipation. [25] The Foley catheter was replaced, the purple urine disappeared, and the urinalysis was sterile; as a result, the patient was discharged in stable conditions. [25]
Diagram of a Foley catheter. Foley first described the use of a self-retaining balloon catheter in 1929, to be used to achieve hemostasis after cystoscopic prostatectomy. [2] He worked on development of this design for use as an indwelling urinary catheter, to provide continuous drainage of the bladder, in the 1930s.
A suprapubic cystostomy or suprapubic catheter (SPC) [1] (also known as a vesicostomy or epicystostomy) is a surgically created connection between the urinary bladder and the skin used to drain urine from the bladder in individuals with obstruction of normal urinary flow.

Hematuria can be classified according to visibility, anatomical origin, and timing of blood during urination. [1] [6]In terms of visibility, hematuria can be visible to the naked eye (termed "gross hematuria") and may appear red or brown (sometimes referred to as tea-colored), or it can be microscopic (i.e. not visible but detected with a microscope or laboratory test).
Contamination of the sample with blood from a non-urinary source, such as from menstruation or rectal bleeding, can mimic hematuria, [99] and microscopic hematuria is sometimes observed in healthy people after exercise. [98] Other causes of microscopic hematuria include UTI, kidney stones, benign prostatic hyperplasia, and trauma to the urinary ...
