3D printing, Ultrastructure of the Glomerular Filtration Barrier and the Nephrotic Syndrome


Nephrotic syndrome (NS) is a clinical condition with high morbidity and mortality, this condition is caused by a failure of the glomerular filtration barrier (GFB) leading to massive proteinuria. In clinical practice, diagnostic, prognostic and therapeutic decisions are based primarily on NS own clinical and histological patterns of each case. The background above underscore the need for a proper understanding of normal and pathological structure GFB. In contrast there are major constraints for obtaining human samples intended for academic teaching today. In this sense, printing three-dimensional (3D) offers the opportunity to solve this deficiency, allowing manufacture teaching materials with the required characteristics and a high degree of detail, at a low cost.

In this work, we have developed two 3D printed models of the GFB ultrastructure, a normal and an altered one by nephrotic syndrome. We hope this tool will improve teaching-learning on one of the most common syndromes in clinical nephrology and allow to subsane the lack of teaching materials. 

The work has been divided into three stages: First one consisted in the production of two figures, based on the representations of human GFB, both normal and pathological according to what is described in the literature*. During second stage the 3D modeling was performed in this structure, using "Tinkercad ©" software, obtaining an ".stl" file. Finally, we proceeded to print the two parts, using a 3D printer: "KREABOT".
