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.
Urine flow is blocked. The Foley catheter must be discarded and replaced. The urethra begins to bleed. The healthcare provider monitors the bleeding. Catheterization introduces an infection into the bladder. The risk of bladder or urinary tract infection increases with the number of days the catheter is in place.
A hematocele that begins bleeding into itself, becoming a hemorrhagic cyst, can easily rupture and cause a number of problems. [11] If the hematocele is older, the tunica sac appears filled with spongy material several times larger than the testicular volume. [8] Most of this material is fibrin and cholesterol granulomas. [8]
The acute management of obstructing clots is the placement of a large (22–24 French) urethral Foley catheter. [17] Clots are evacuated with a Toomey syringe and saline irrigation. [17] If this does not control the bleeding, management should escalate to continuous bladder irrigation (CBI) via a three-port urethral catheter. [17]

The catheter is then carefully navigated through the arterial system with x-ray guidance until it reaches the branches of the superior rectal artery that supply blood to the hemorrhoidal plexus. [3] Once in position, microparticles and/or microcoils are injected through the catheter to block these arteries, thereby reducing the blood supply to ...
