title: Flow visualization in uroendoscopy: the steal effect.
abstract: Balanced continuous flow resection has been offered as the best form of irrigation in uroendoscopy. Although it will keep the bladder pressure low, using flow visualization techniques it has been demonstrated that it does not fulfil the requirements of an irrigating fluid when used in a confined environment such as the prostatic urethra. The outflowing irrigating fluid has been shown to be taken directly from the inflowing jet ('steal effect') thereby reducing the effectiveness of the irrigating jet on the working area of the resectoscope.
