suprapubic catheter
Also written as: SP — suprapubic
Surgical drainage tube inserted directly through the abdominal wall into the bladder, bypassing the urethra for urinary diversion.
Full Definition
A suprapubic catheter is a urinary drainage device inserted surgically through the anterior abdominal wall directly into the bladder dome, providing an alternative route for urine drainage that bypasses the urethra entirely. In pediatrics, this procedure is typically performed under general anesthesia and is indicated for conditions such as severe urethral strictures, complex hypospadias repairs, or when prolonged urethral catheterization is contraindicated. The catheter exits through a small incision above the pubic bone and connects to a drainage bag system. This approach reduces the risk of urethral trauma and infection compared to transurethral catheterization, particularly in patients requiring long-term bladder drainage.
Usage
Usage note: Often abbreviated as SP catheter. Distinguish clearly from transurethral catheters in clinical documentation.
