The volume in the bladder should not affect the VLPP as long as the detrusor pressure is kept at a level that does not affect the urethra.
The purpose of this study was to compare the VLPP and CLPP in urodynamically proven SUI women at different bladder volumes to evaluate whether the bladder volume can affect the LPP, to examine the relationship between VLPP and CLPP, and to determine if LPP would be changed by the incontinence severity to evaluate whether the bladder volume can affect the LPP.
A total of 228 women with urodynamically proven SUI who underwent serial VLPP and CLPP measurements at bladder volumes of 150, 200, 250, and 300 mL between January 2009 and December 2011 were included in this study.
(15) Measurement of VLPP was performed with the patient in lithotomy position on an urodynamic table.
The mean value of VLPP and CLPP according to the bladder volume, and LPP according to the Stamey grade are shown in Tables 1 and 2.
Both the VLPP and CLPP measurements were affected by Stamey grade.
Presently, we evaluated the relationship between VLPP and CLPP, and the change of LPP with different bladder volumes in SUI women.
A uniform definition of ISD is presently lacking and tests used to diagnose ISD include low VLPP.
VLPP measurement offers an objective means of assessing urethral function and incontinence, which is the intra-abdominal pressure that can overcome urethral resistance and cause urine leakage.
CLPP can also be used to test for SUI when the measurement of VLPP is impossible.
(18) The progressive lowering of VLPP in the same patients as the bladder volume increased has been reported in urodynamic studies.
