comparison between elevate anterior apical system and Perigee system in pelvic organ prolapse surgery clinical and sonographic outcomes
International Urogynecology Journal, 2015Co-Authors: Nazura Bt Karim, Eileen Feliz M Cortes, Yihao Lin, Yiap Loong TanAbstract:The aim of this study was to assess the incidence of de novo stress urinary incontinence (SUI) and sonographic features of implanted transvaginal mesh in continent women treated with Elevate™ anterior/apical [single-incision mesh (SIM-A)] or Perigee™ [transvaginal mesh with sacrospinous fixation (TVM + SSF)] in extensive pelvic organ reconstruction surgery. This prospective observational study was done from May 2010 to January 2013. Patients were recruited from two tertiary centers, and the Elevate™ and Perigee™ systems were compared. Patients who had overt or occult SUI, previous prolapse or mesh insertion were excluded. Fifty-seven patients in the SIM-A group and sixty-one in the TVM + SSF group were analysed. All completed a minimum of 1-year follow-up. Groups were demographically and statistically similar. There was a significantly high incidence of de novo SUI postoperatively in the SIM-A group. The objective and subjective cure rate of pelvic organ prolapse (POP) were comparable between groups, with incidence of mesh erosion in the SIM-A group and three in the TVM + SSF group. Sonographic evaluation showed significant increase in mesh length in the SIM-A group. Elevate™ a offered lower incidence of mesh erosion and comparable results on anatomical POP correction; however, incidence of de novo SUI was high. There is an apparent lengthening of implanted Elevate® mesh sonographically.

Clinical Study Comparison of Clinical Outcomes Using ''Elevate Anterior'' versus ''Perigee'' System Devices for the Treatment of Pelvic Organ Prolapse
2020Co-Authors: Cheng-yu Long, Chiu-lin Wang, Kun-ling Lin, Cheng-min Liu, Eing-mei Tsai, Ching-ju ShenAbstract:Objective. This study aims to compare clinical outcomes using the Perigee versus Elevate anterior devices for the treatment of pelvic organ prolapse (POP). Study Design. One hundred and forty-one women with POP stages II to IV were scheduled for either Perigee ( = 91) or Elevate anterior device ( = 50). Preoperative and postoperative assessments included pelvic examination, urodynamic study, and a personal interview about quality of life and urinary symptoms. Results. Despite postoperative point C of Elevate group being significantly deeper than the Perigee group (median: −7.5 versus −6; < 0.01), the 1-year success rates for two groups were comparable ( > 0.05). Apart from urgency incontinence, women with advanced POP experienced significant resolution of irritating and obstructive symptoms after both procedures ( < 0.05), generating the improvement in postoperative scores of Urogenital Distress Inventory (UDI-6) and Incontinence Impact Questionnaire (IIQ-7) ( < 0.01). On urodynamics, only the residual urine decreased significantly following these two procedures ( < 0.05). Women undergoing Perigee mesh experienced significantly higher visual analogue scale (VAS) scores and vaginal extrusion rates compared with the Elevate anterior procedure ( < 0.05). Conclusions. With comparable success rates, the Elevate procedure has advantages over the Perigee surgery with lower extrusion rate and postoperative day 1 VAS scores

determination of frame dragging using earth gravity models from champ and grace
New Astronomy, 2006Co-Authors: Ignazio Ciufolini, E C Pavlis, R PeronAbstract:Abstract Using the new generation Earth’s gravity field models EIGEN-2S, GGM01S and EIGEN-GRACE02S generated by the space missions CHAMP and GRACE, we have obtained an accurate measurement of the Lense–Thirring effect with the LAGEOS and LAGEOS II satellites analyzing about 10 years of data with the EIGEN-2S and GGM01S models and about 11 years of data with EIGEN-GRACE02S. This new analysis is in agreement with our previous measurements of the Lense–Thirring effect using the LAGEOS satellites and obtained with the JGM-3 and EGM96 Earth’s models. However, the new determinations are more accurate and, especially, more robust than our previous measurements. In the present analysis we are only using the nodal rates of the two satellites, making no use of the Perigee rate, as in our previous analyses. The Perigee is affected by a number of non-gravitational perturbations difficult to be modelled and whose impact in the total error budget is not easy to assess. Using the EIGEN-2S model, we obtain a total error budget between 18% and 36% of the Lense–Thirring effect due to all the error sources. Specifically, by using EIGEN-2S, we obtain: μ = 0.85, with a total error between ±0.18 and ±0.36, with GGM01S we get μ = 1.06 with a total error between ±0.19 and ±0.24 and with EIGEN-GRACE02S we obtain μ = 0.99, with a total error between ±0.05 and ±0.1, i.e., between 5% and 10% of the general relativistic predicted value of the Lense–Thirring effect. In addition to the analyses using EIGEN-2S, GGM01S and EIGEN-GRACE02S without the use of the Perigee, we have also performed an analysis using the older model EGM96 with our previous method of combining the nodes of the LAGEOS satellites with the Perigee of LAGEOS II. However, this analysis was performed over a period of about 10 years, i.e. about 2.5 times longer than any our previous analysis. The result using EGM96 over this longer period of observation agrees with our previous results over much shorter periods and with the EIGEN-2S, GGM01S and EIGEN-GRACE02S measurements of μ. In addition to the accurate determination of frame-dragging and in agreement with our previous analyses of the orbits of the LAGEOS satellites, we have observed, since 1998, an anomalous change in the Earth quadrupole coefficient, J2 which agrees with recent findings of other authors. This anomalous variation of J2 is accurately observed both on the node of LAGEOS and LAGEOS II and it is independent of the model used, i.e., it is observed by using the model EGM96 or by using EIGEN-2S, GGM01S or EIGEN-GRACE02S. However, this anomalous variation of the Earth quadrupole coefficient does not affect at all our determination of the Lense–Thirring effect thanks to the total elimination of the J2-induced errors with our especially devised estimation technique.

measuring the relativistic Perigee advance with satellite laser ranging
Classical and Quantum Gravity, 2002Co-Authors: Lorenzo Iorio, Ignazio Ciufolini, E C PavlisAbstract:The pericentric advance of a test body by a central mass is one of the classical tests of general relativity. Today, this effect is measured with radar ranging by the perihelion shift of Mercury and other planets in the gravitational field of the Sun, with a relative accuracy of the order of 10−2–10−3. In this paper, we explore the possibility of a measurement of the pericentric advance in the gravitational field of Earth by analysing the laser-ranged data of some orbiting, or proposed, laser-ranged geodetic satellites. Such a measurement of the Perigee advance would place limits on hypothetical, very weak, Yukawa-type components of the gravitational interaction with a finite range of the order of 104 km. Thus, we show that, at the present level of knowledge of the orbital perturbations, the relative accuracy, achievable with suitably combined orbital elements of LAGEOS and LAGEOS II, is of the order of 10−3. With the corresponding measured value of (2 + 2γ − β)/3, by using η = 4β − γ − 3 from lunar laser ranging, we could get an estimate of the PPN parameters γ and β with an accuracy of the order of 10−2–10−3. Nevertheless, these accuracies would be substantially improved in the near future with the new Earth gravity field models by the CHAMP and GRACE missions. The use of the Perigee of LARES (LAser RElativity Satellite), with a suitable combination of orbital residuals including also the node and the Perigee of LAGEOS II, would also further improve the accuracy of the proposed measurement.

measuring the relativistic Perigee advance with satellite laser ranging
arXiv: General Relativity and Quantum Cosmology, 2001Co-Authors: Lorenzo Iorio, Ignazio Ciufolini, E C PavlisAbstract:One of the most famous classical tests of General Relativity is the gravitoelectric secular advance of the pericenter of a test body in the gravitational field of a central mass. In this paper we explore the possibility of performing a measurement of the gravitoelectric pericenter advance in the gravitational field of the Earth by analyzing the laser-ranged data to some existing, or proposed, laser-ranged geodetic satellites. At the present level of knowledge of various error sources, the relative precision obtainable with the data from LAGEOS and LAGEOS II, suitably combined, is of the order of $10^{\rm -3}$. Nevertheless, these accuracies could sensibly be improved in the near future when the new data on the terrestrial gravitational field from the CHAMP and GRACE missions will be available. The use of the Perigee of LARES (LAser RElativity Satellite), in the context of a suitable combination of orbital residuals including also LAGEOS II, should further raise the precision of the measurement. As a secondary outcome of the proposed experiment, with the so obtained value of $\ppn$ and with $\et=4\beta-\gamma-3$ from Lunar Laser Ranging it could be possible to obtain an estimate of the PPN parameters $\gamma$ and $\beta$ at the $10^{-2}-10^{-3}$ level.
