Assessment of VLPP has prognostic meaning, but measurement techniques are still subject to controversy. <i>Patients and Methods:<\/i> One hundred and eight consecutive women with no genital prolapse or bladder hyperactivity exclusively presenting with urinary stress incontinence were submitted to VLPP determination during urodynamic evaluation using a rectal and urethral catheter. Rectal pressure measurement served as the landmark in the determination of Valsalva\u2019s maneuver. After determining the rectal pressure, the urethral probe was pulled out and the maneuver repeated. <i>Results:<\/i> Eighty-four cases (group I) presented leakage during Valsalva\u2019s maneuver with the urethral catheter being in place. Group Ia (66.6%) had a reduction of 44.5 cm H<sub>2<\/sub>O in the rectal pressure after catheter removal. In group Ib, rectal leakage pressure increased after catheter removal from 76.5 \u00b1 18.7 to 79.5 \u00b1 24.7 cm H<sub>2<\/sub>O. Eight patients did not demonstrate urine leakage after catheter removal. In group II, 24 cases showed a rise in rectal leakage pressure to 76.2 \u00b1 22 cm H<sub>2<\/sub>O, but urinary leakage was only observed after catheter removal. In group IIa (19 cases), the VLPP decreased by 12.6 \u00b1 15 cm H<sub>2<\/sub>O, while in group IIb (5 cases) leakage occurred only in patients showing an increase of 22.2 \u00b1 7 cm H<sub>2<\/sub>O in the rectal pressure after the second maneuver with the urethral catheter in position. <i>Conclusions:<\/i> Precise determination of the abdominal leak point pressure through Valsalva\u2019s maneuver may be critical. The different techniques used for VLPP determination may render comparisons difficult. Rectal pressure measurement with no urethral catheter in place to monitor abdominal leak pressure seems to be more appropriate because it resembles clinical practice. Although lower abdominal leakage pressures may be found, this is not a uniform finding, and a higher incidence of type III incontinence may be expected, and critical analysis or painstaking repetition may be required in the case of lack of demonstration of urinary loss.<\/jats:p>","DOI":"10.1159\/000090880","type":"journal-article","created":{"date-parts":[[2006,2,22]],"date-time":"2006-02-22T11:46:38Z","timestamp":1140608798000},"page":"154-158","source":"Crossref","is-referenced-by-count":5,"title":["Valsalva Leak Point Pressure to Determine Internal Sphincter Deficiency in Stress Urinary Incontinence"],"prefix":"10.1159","volume":"76","author":[{"given":"Paulo","family":"Rodrigues","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuri","family":"Afonso","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Flavio O.","family":"Hering","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jo\u00e3o C.","family":"Campagnari","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alberto","family":"Azoubel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2006,2,24]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016%2FS0022-5347%2805%2965546-2"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016%2FS0002-9378%2896%2970243-0"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016%2FS0094-0143%2805%2970309-8"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1046%2Fj.1464-410x.2000.00947.x"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1002%2F1520-6777%282000%2919%3A6%3C677%3A%3AAID-NAU5%3E3.0.CO%3B2-J"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016%2F0029-7844%2895%2900173-O"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1034%2Fj.1600-0412.1998.771010.x"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016%2FS0022-5347%2805%2965089-6"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016%2FS0090-4295%2802%2901600-X"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1016%2F0090-4295%2882%2990371-5"}],"container-title":["Urologia Internationalis"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/90880","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/90880","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T02:48:49Z","timestamp":1745462929000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000090880"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2006]]},"references-count":10,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2006,2,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000090880","archive":["Portico"],"relation":{},"ISSN":["0042-1138","1423-0399"],"issn-type":[{"type":"print","value":"0042-1138"},{"type":"electronic","value":"1423-0399"}],"subject":[],"published":{"date-parts":[[2006]]}}}
