“…Fluoroscopy is not always easily accessible and in the absence of fluoroscopy urine leakage is best detected by direct vision. 6 In this study during the performance of both Valsalva and cough maneuvers, visual inspection of the external urethral meatus was performed by the observer and the exact moment when the leakage had occurred was recorded. Performing the maneuvers in increasing intensities and giving a pause subse- quently for inspection, led the observer make a reliable detection of LPP.…”

“…5 These catheters might significantly increase the pressure reading at leakage even some patients may not leak with such a catheter. 6,7 The aim of this study is to investigate the effect of cystometry catheter on ALPP measurement and compare the sensitivity of Valsalva and cough maneuvers in demonstrating urinary leakage in women with stress urinary incontinence.…”

Valsalva Leak Point Pressure to Determine Internal Sphincter Deficiency in Stress Urinary Incontinence

Introduction: Valsalva leak point pressure (VLPP) represents the global competence of the conjunctive forces around the urethra to support increased pressure from the abdominal cavity with transmission to the bladder. Assessment of VLPP has prognostic meaning, but measurement techniques are still subject to controversy. Patients and Methods: 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’s maneuver. After determining the rectal pressure, the urethral probe was pulled out and the maneuver repeated. Results: Eighty-four cases (group I) presented leakage during Valsalva’s maneuver with the urethral catheter being in place. Group Ia (66.6%) had a reduction of 44.5 cm H₂O in the rectal pressure after catheter removal. In group Ib, rectal leakage pressure increased after catheter removal from 76.5 ± 18.7 to 79.5 ± 24.7 cm H₂O. 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 ± 22 cm H₂O, but urinary leakage was only observed after catheter removal. In group IIa (19 cases), the VLPP decreased by 12.6 ± 15 cm H₂O, while in group IIb (5 cases) leakage occurred only in patients showing an increase of 22.2 ± 7 cm H₂O in the rectal pressure after the second maneuver with the urethral catheter in position. Conclusions: Precise determination of the abdominal leak point pressure through Valsalva’s 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.

Evaluation of intraluminal pressure in cystorrhaphies with and without intestinal serosal patch supplementation from canine cadavers

PURPOSE:To evaluate the maximal intraluminal pressure (MIP) supported by canine cadaveric urinary bladders that underwent cystotomy followed by cystorraphy, with and without serosal patching-supplementation. METHODS:Two groups (n=8 each) were formed, and in one (conventional) the cystotomy was closed with cushing pattern. In the other group (serosal), the same procedure was performed, and a piece of jejunum was used for the construction of the serosal patching over the cystorraphy. MIP was measured by means of an invasive blood pressure transducer with closed stopcock attached to a multiparameter monitor. At the end of each measurement, the bladder body circumference was assessed. RESULTS:Mean±SD MIP sustained for the conventional and serosal groups were 28.88±5.08 and 65.38±10.99 mmHg, respectively (p<0.0001). Bladder circumference did not change significantly between groups (p=0.35) and did not correlate with MIP assessed in conventional (p=0.27; r=0.4379) and serosal groups (p=0.37; r=-0.3637). CONCLUSION:Serosal patch-supplemented cystorraphies were able to sustain intraluminal pressures 55.8% higher, than nonsupplemented cystorraphies in specimens from canine cadavers.
