The urethral meatus should be examined after trauma. [1] Blood at the urethral meatus precludes insertion of a foley catheter into the bladder. [1] Erroneously placing a foley in this situation can result in infections of periprostatic and perivesical hematomas or conversion of a partial transection to a complete urethral transections. [1]
Urethral trauma is the only absolute contraindication to the placement of a urinary catheter. Examination findings such as blood at the urethral meatus, or a high riding prostate necessitate a retrograde urethrogram prior to insertion.
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.
Rupture of the urethra is an uncommon result of penile injury, incorrect catheter insertion, straddle injury, or pelvic girdle fracture. The urethra, the muscular tube that allows for urination, may be damaged by trauma. When urethral rupture occurs, urine may extravasate (escape) into the surrounding tissues.
Filling up the bladder with contrast material without full catheterisation (the end of catheter inside the urethra) is also possible if the subject is able to relax the bladder neck to allow contrast material to flow into the bladder. [4] If a urethral injury is suspected, a retrograde urethrography should be performed before attempting to ...
A tube called a catheter can be inserted through the urethra to drain urine from the bladder, called an indwelling urinary catheter; or, to bypass the urethra, a catheter may be directly inserted through the abdominal wall into the bladder, called a suprapubic catheter. [28]
When in acute urinary retention, treatment of the urethral stricture or diversion is an emergency. Options include: Urethral dilatation and catheter placement. This can be performed in the Emergency Department, a practitioner's office or an operating room. The advantage of this approach is that the urethra may remain patent for a period of time ...
Trauma, iatrogenic injury and infections are the most common causes of urethral injury/defect requiring repair. Urethroplasty is regarded as the gold standard treatment for urethral strictures and offers better outcomes in terms of recurrence rates than dilatations and urethrotomies .
