AB039. Preparation and application of bladder irrigation colourimetric card after transurethral operation

Transurethral surgery is a kind of routine operation in urology department which mainly includes transurethral resection of the prostate (TURP) and transurethral resection of bladder tumor (TUR-BT). Because of the inevitable exudation after this type of surgery, continuous bladder irrigation is necessary. Not only can successful irrigation provide an effective blood drainage of the prostatic fossa and bladder, but preliminarily reflect patients postoperative blood loss and guide the clinical management. Thus, urethral blotting by blood clots and dysuria can be avoided. Traditional bladder irrigation speed is regulated by observing rinses color empirically. This method is strongly subjectively, caused a lot of randomness and blindness for clinical work, leaving patients in postoperative safety hidden troubles. Unfortunately, no uniform standard rinse color was set so far. Therefore, a method of quantifying the color of bladder rinse solution is urgently needed to solve the above problems. Standard bladder irrigation colourimetric card was developed and preliminarily used in clinical after the carefully summary and unremitting efforts of urologic doctors in our hospital. By this mean, the defects of traditional bladder irrigation can be made up scientifically. Nevertheless, some limitations still exist in this program such as light interference and poorly resolution capability of naked eye. Hence intelligent colorimetric device and accurate irrigation speed control system should be further developed to quantify the whole procedure more scientifically and precisely, thus making the bladder irrigation more standardized and normalized.
