Evandilson Guenes Campos de Barros, Salvador Vilar Correia Lima, Fabio de Oliveira Vilar, Eugenio Soares Lustosa, Roberto Santos Lima
Open Journal of Urology (OJU) , 2013, DOI: 10.4236/oju.2013.36046

Introduction: Percutaneous approach to the kidney is a very useful alternative in renal surgery which minimizes the morbidity of a variety of procedures. Objectives: To evaluate the efficacy, practicity of a reusable system of metallic coaxial dilator coupled to a special puncture needle to perform lumbar puncture and dilation of the percutaneous tract. Methods: A randomized experimental study was carried out involving 50 individuals. These patients were randomized as follows: Group 1 had the procedure performed with the conventional disposable Amplatz set traditionally used for this procedure. Patients in Group 2 were operated utilizing the new reusable coaxial set specially designed for this purpose. The following parameters were measured to compare the 2 groups: sex Corporeal Mass Index (CMI), Pre and postoperative hematocrit and hemoglobin. Time interval between the puncture, dilation and access to the renal pelvis and insertion of the nephroscope were also analyzed. Results: There was no statistical difference between the 2 groups concerning hematocrit and hemoglobin changes when comparing prewith postoperative period. Patients in Group 2 required a significant lower time between puncture and final access to the upper collecting system. Conclusion: The new coaxial dilator set showed to be as safe as the conventional Amplatz set with the advantage of reusability and decrease of tract

A New Biomaterial for Urinary Catheters  [PDF]
Roberto Santos Lima, Salvador Vilar Correia Lima, José Lamartine De Andrade Aguiar, Eziel Cavalcanti Vasconcelos Rocha, Flávia Cristina Morone Pinto
Journal of Biomaterials and Nanobiotechnology (JBNB) , 2018, DOI: 10.4236/jbnb.2018.91001
Abstract: Several studies argue that an ideal biomaterial for urinary catheters is utopian. Based in literature review it seems to be true. However, research advances: the biomaterial itself, new designs, new coatings, associated drugs, etc. Once implanted and interacting with urine, two old problems persist: encrustation and bacterial colonization. In this context, an extracellular product from bacterial synthesis on sugarcane molasses biomaterial has been studied in several experimental and clinical studies. Based on its high biocompatibility, the aim of this study is to evaluate its performance in an in vivo model as an endourologic prosthesis implanted in the bladder of Wistar rats. We evaluate physical, chemical and biological phenomena in comparison to an already established biomaterial, polyurethane. Even though it is not a finished product, the sugarcane biopolymer presented similar performance compared to polyurethane in several analyzed parameters and has an important characteristic: low cost.

M. C. de Albuquerque Neto, Leslie Clifford Noronha Araujo, Thome Decio Pinheiro Barros Junior, Joao Luiz Amaro, Flavia Cristina Morone Pinto, Fabio de Oliveira Vilar, Salvador Vilar Correia Lima
Open Journal of Urology (OJU) , 2017, DOI: 10.4236/oju.2017.73008
Abstract: Aim: To determine whether bladder functions deteriorate with age. Methods: Data contained in electronic medical record (INFOMED?) were used in this institutional retrospective review. Analysis was done on the urodynamic studies in women over 18 years old conducted between May 2011 and November 2015. Patients with previous history of pelvic surgery or radiotherapy, neurological disease, vaginal prolapse greater than grade I, congenital urogenital malformations, urinary obstructive disease, diabetes, or the use of any medication that could interfere with bladder function were excluded from the analysis. The urodynamic parameters analyzed were the Maximum Cystometric Capacity (MCC), Voiding Volume (VV), Maximum Flow (Qmax), Bladder Compliance (BC), Detrusor Pressure at Maximum Flow (PdetQmax), Bladder Contractility Index (BCI), Bladder Voiding Efficiency (BVE) and Post-Void Residual Urine Volume (PVR). Patients were further stratified in five groups according to age (A—18 to 40; B—41 to 50; C—51 to 60; D—61 to 70; E—over 70 years old). Results: Out of 3103 urodynamic studies analyzed, 719 were eligible for the study. The average age of patients was 49.3 (+13.2) years old and in all evaluated parameters, statistically significant correlation between age and decline of bladder function was obtained (p < 0.05). Moreover, mathematical equations were presented to estimate the parameters values in relation to age. Conclusions: This study showed a decline in bladder storage function (reduction in MCC and BC) and in bladder emptying function (reduction in Qmax, PdetQmax, VV, BCI and BVE with an increase in PVR) with age.

Abstract: objectives: suture materials are widely used in urology. the interaction of these materials with the extracellular matrix in the inflammatory process can be estimated by stereology of collagen fibers and the present study was designed to determine the behavior of the bladder tissue of rats to grafts of the biopolymer of sugar cane (bpca), and the inflammation and intravesical stone formation compared to the polyglactin 910. materials and methods: 42 wistar rats were divided in four groups: group i (n = 10) rats submitted to bladder implantation of ~4-0 bpca suture graft and euthanized at 4 weeks; group ii (n = 10) rats submitted to bladder implantation of 4-0 polyglactin 910 suture graft and euthanized at 4 weeks; group iii (n = 12) rats submitted to bladder implantation of ~4-0 bpca suture graft and euthanized at 8 weeks; group iv (n = 10) rats submitted to bladder implantation of 4-0 polyglactin 910 suture graft and euthanized at 8 weeks. bladders collected at necropsy were analyzed for their weight and the presence of grafts and calculi. sections were prepared for stereological analysis of collagen fibers. results: the bladder weight was higher in group i, particularly in the presence of bladder stones. the presence of the graft was observed in 100% (group i), 80% (group ii), 91.6% (group iii) and 30% (group iv); polyglactin 910 showed an absorption of 70% in this period. the stereological analysis showed a higher volume density of collagen fibers in group i versus other groups (p < 0.001). conclusion: the bpca was a material with good integration into the bladder of rats; its absorption was slower than that of the polyglactin 910. the presence of urinary stones was lower in bladders with implantation of bpca, particularly after 8 weeks. there was a greater initial inflammatory response to bpca graft that was directly related to the increase in bladder weight and the presence of urinary stones, but that equalized the results of polyglactin 910 after 8 weeks.

Abstract: the article presents a part of the research "terms and concepts of museology", subject of specialty language, addressing the theory and practice that represent an area of knowledge, and which is expressed by the scientific communication (context of information/communication). in historical perspective, focuses on the intertwining museology-museum and heritage from the training grounds of the museum, museological field, and heritage. highlights processes of institutionalization of cultural objects (symbolic goods), namely patrimonialization and musealization, and its constructed meanings, over time, legitimizing the actions of 'ownership' of cultural bodies. the theoretical support has involved theoretical studies of museology, communicative theory of terminology, socioterminology, economic theory of fields and symbolic power, law, and information science. the objectives included analyzing the dynamics of creation, redefinition, change of terms/concepts, with results that provide subsidies for documentary language. the methodology developed comparative analysis of sources relating to representations and practices of the museological, heritage and terminological scenarios. the results showed one common basis for interaction between museology and heritage: the image publicizing the need to safeguard the assets for transmission to future generations - preservation, embodied in the sense borrowed from social act on the issue of identity, but whose real face is the practice of symbolic power.

Os contornos da crise e das rupturas vividas pela universidade contemporanea
Manolita Lima Correia
Eccos Revista Científica , 2003,
Abstract: This text aims to identify and discuss the reasons that led the university into crisis and ruptures, particularly the contemporarily. The discussions are based on the following assumptions: a) the never-ending crisis comes from the efforts to adapt and/or adjust to environment demands; b) the survival process has been obtained at a damaging cost of its academic ethos, which is its raison d′être as institution. The consulted bibliography allowed the establishment of some relations between these crisis/ruptures and the absence of a real democratic project associated to an uneven subordination to exogenous interests
