“…Studies also have established the correlation between the Pabd and BMI in patients with abdominal compartment syndrome. 10 Meanwhile, Richter et al have demonstrated a significant correlation between Pves and Pabd and abdominal circumference in the overweight and obese female patients. 18 However, there are no previous studies having attempted to correlate Pves and Pabd with obesity-related measurements in the AFC system.…”

“…In WFC system, it has been reported that body mass index (BMI) correlated with Pves and Pabd 8,9 .

ObjectivesTo establish the initial (before pressure equilibrium) and initial resting intravesical and abdominal pressure in the sitting position using air‐filled catheters, to assess the correlation between these pressures and obesity‐related measurements, and to estimate if obesity‐related measurements can be a guide to interpret initial and initial resting pressures in urodynamic testing.MethodsPatients with non‐neurogenic lower urinary tract symptoms referred for urodynamic testing in our center were consecutively enrolled in a prospective study from August 2022 to October 2022. The correlation between the initial and initial resting pressures (before and after pressure equilibrium) and obesity‐related measurements were analyzed using Pearson's correlation coefficient and multiple linear regression analysis.ResultsNinety‐eight patients aged 56 ± 16 were studied. The 95% range of the initial intravesical and abdominal pressure were 18–42 cmH2O and 21–60 cmH2O, respectively. The initial resting intravesical, abdominal, and detrusor pressure in the 95% range were 17–41, 16–42, and −5 to 4 cmH2O, respectively. Over the multiple analysis, abdominal fat thickness, and body mass index (BMI) correlated independently with initial intravesical pressure, and only visceral fat grade correlated with initial abdominal pressure. BMI correlated independently with initial resting intravesical pressure.ConclusionsOur results determined the ranges of values of both initial and initial resting pressures in the air‐charged system. Meanwhile, the present study indicated the obesity‐related measurements may be used as a guide to interpret the initial and initial resting pressures in urodynamic testing, and may provide a reference for the quality control of these pressures.

IntroductionThe International Continence Society recommends zeroing of transducers to the atmospheric pressure for invasive urodynamics. The range of abdominal pressure relative to atmospheric pressure is well‐known in adults but has not been described in children. This prospective observational study was carried out to establish baseline abdominal in children.Materials and MethodsProspective, multicenter, observational study of 100 children aged 0‐18 years undergoing invasive urodynamics using water‐filled systems. Initial resting abdominal pressure, intravesical pressure and detrusor pressure were recorded in supine, sitting, and standing position (as age‐ and diagnosis‐appropriate). This data was analyzed using SPSS 20.0.0 with regard to age, gender, height, weight, body mass index, and underlying diagnosis (classified as neurogenic or non‐neurogenic). Nonparametric tests were used (2‐sided p < 0.05, significant).ResultsInitial resting abdominal pressure (inter‐quartile range) in children was between 5 and 15 cmH2O in the supine, 13−20 cmH2O in the sitting, and 15−21 cmH2O in the standing position. These pressures were not consistently influenced by age, gender, height, weight or underlying diagnosis. The initial resting detrusor pressure was noted to be 0−4 cmH2O without any difference based on posture. Limitations include use of two‐tube technique, relatively small number of subjects across each age group, wide range of underlying diagnoses and need for manual smoothing of some traces.ConclusionThis study defines initial resting abdominal pressure at urodynamics in children and notes that, as with adults, it is possible to define widely applicable ranges regardless of individual characteristics. These pressures appear lower than those noted historically in adults.

Introduction Increased intraperitoneal pressure (IPP) is associated with abdominal wall complications and technical failure in peritoneal dialysis. Since the standard measurement of IPP is limited due to its cumbersome procedures, we aimed to develop and validate equations for evaluating IPP (eIPP). Methods A cross-sectional study. Totally 200 prevalent PD patients were divided into development and validation datasets after random sampling matched by body mass index. The IPPs were measured using the Durand method, with whole-body and abdominal anthropometry indices collected. Equations with 2.0 L and 1.5 L fill volume were generated by stepwise linear regression modeling respectively. The bias, accuracy and precision of eIPP with 2 L and 1.5 L fill volume were compared with actual IPP by Durand method respectively. The eIPP for 2 L fill volume was also compared with other existing equations. Results Two new equations both incorporating waist and height from decubitus plane to midaxillary line were generated. The value of eIPP exhibited small biases in relation to golden standard, with median differences of -0.24 cmH2O and -0.10 cmH2O for 2 L and 1.5 L respectively. The precisions evaluated by the SD of the absolute value of the differences were 2.59 cmH2O and 2.50 cmH2O respectively. The accuracies evaluated by the value of 1-P20 for eIPP were 26% for 2.0 L and 27% for 1.5 L. Better bias, precision and accuracy were observed for the eIPP equation compared with other existing equations for 2.0 L fill volume. Conclusions We provided two new equations, first developed from abdominal anthropometry indices, to accurately estimate the IPP in the PD population.
