Endoscopy, 30(9), 778-780. doi: 10.1055/s-2007-10014210013-726Xhttps://dx.doi.org/10.1055/s-2007-1001421https://hdl.handle.net/20.500.12395/16774Background and Study Aims: The accuracy of transurethral bladder catheter pressure in reflecting intra-abdominal pressure is well defined in experimental studies and case reports but not in controlled clinical trials. Patients and Methods: We compared bladder pressure with insufflator pressure during laparoscopic cholecystectomy in 40 patients. Measurements were made at four pressure levels of the insufflator: 0, 5, 10 and 15 mmHg. Results: When the insufflator displayed 0, 5, 10, and 15 mmHg (0, 6.8, 13.6 and 20.4 cmH(2)O), and the mean bladder pressures measured 2.5 +/- 1.4, 7.3 +/- 1.5, 12.9 +/- 1.6 and 19.7 +/- 1.5 cmH(2)O, respectively, The two measurements correlated well with each other (r = 0.973, P < 0.0001). Conclusion: We concluded that bladder pressure measured by transurethral catheter was equal to insufflator pressure during laparoscopy, and that this was a valid indicator of intra-abdominal pressure.en10.1055/s-2007-1001421info:eu-repo/semantics/openAccessArticle3097787809932758Q1WOS:000078316700007Q1
