There were no differences in objective or subjective success rates when the analyses were adjusted for VLPP
or maximum urethral closure pressure (MUCP).
40% patients have VLPP
of 60-80 cm [H.sub.2]O and 60% have 80-120 cm H2O.
The VLPP was positive in only one patient at an abdominal pressure of 65 cm[H.sub.2]O.
The VLPP was positive for two patients (abdominal pressures of 37 and 65 cm[H.sub.2]O) at 3 months and one patient (abdominal pressure = 73 cm[H.sub.2]O) at 6 months.
The VLPP was low in only one patient at 3-month follow-up.
Variables associated with the need for repeat treatment included indicators of more severe incontinence, including leak point pressure of 60 cm [H.sub.2]O or lower (OR, 7.3), history of urethrolysis (OR, 6.2), low MUCP (OR, 3.5), VLPP
of 60 cm [H.sub.2]O or lower (OR, 3.5), five or more incontinent episodes per day (OR, 3.0), and a positive empty supine test (OR, 2.7).
This randomized, prospective study of 164 women who had SUI and ISD (defined as MUCP <20 cm [H.sub.2]O or VLPP
<60 cm [H.sub.2]O) randomized subjects to placement of a retropubic sling or a TOT sling.
However, VLPP measurement is still controversial, and the VLPP value can be affected by various factors, such as bladder volume, catheter insertion, catheter size, patient position, and pelvic organ prolapsed.
Cough-induced LPP (CLPP) is another way to test for stress incontinence, especially when the measurement of VLPP is impossible because not enough pressure can be produced from the Valsalva maneuver.
VLPP was defined as the lowest intravesical pressure at 200 mL of bladder capacity during valsalva that produced urine leakage.
The objective cure rate was defined as no leakage at all during the VLPP studies.
All patients were evaluated with history including the number of pads used per day, physical examination including pelvic examination, urinalysis, urogenital distress inventory (UDI-6), analog global satisfaction scale (GSS), pad weight test, urodynamic studies included filling cystometry and Valsalva leak point pressure (VLPP
