What is the primary purpose of a 3-way continuous bladder irrigation (CBI) after TURP?

The primary purpose of a 3-way continuous bladder irrigation (CBI) after transurethral resection of the prostate (TURP) is to keep the catheter clear of clots and to facilitate the drainage of urine. Following TURP, there is a risk of bleeding and the formation of blood clots in the bladder. The continuous irrigation helps to wash out any clots that might obstruct the catheter, ensuring that urine can flow freely and preventing urinary retention. This is crucial for preventing complications such as bladder distension or infection, which can arise from blocked urinary drainage.

In addition, this irrigation helps maintain a clear path for the urine to flow, allowing for accurate monitoring of urine output and any potential bleeding. By ensuring the catheter remains patent and the bladder is consistently flushed, CBI plays a vital role in post-operative care after TURP, improving patient outcomes and comfort following this procedure.
