  • Title: The use of a bladder pressure warning device during transurethral prostatic resection decreases absorption of irrigation fluid.
    Author: Hjertberg H, Pettersson B.
    Journal: Br J Urol; 1992 Jan; 69(1):56-60. PubMed ID: 1737254.
    Abstract:
    During a period of 4 weeks 102 patients underwent transurethral prostatic resection (TURP). Of these, 50 were randomly allocated to the use of an intravesical pressure device which warned the surgeon at a pressure elevation of 1.5 kPa. Ethanol (1%) was used as a marker in the irrigation fluid (glycine 2.2%), and absorption of ethanol-tagged irrigation fluid was detected by measurements in the expired air. In 28 patients absorption took place (in 8 of the 50 patients equipped with the warning device and in 20 of the 52 without the device). The greatest absorption was seen in the group without the device. No differences were found between the groups with regard to age, resected mass, resection time, resection speed, or haemorrhage. Patients who absorbed irrigation fluid were slightly older and bled more, and the resected mass was larger. The use of a pressure warning device reduces the amount of irrigation fluid absorbed and the number of patients who absorb irrigation fluid, and minimises the risk of the TUR syndrome.
