THE PROBLEM A SOLUTION

THE PLOT THICKENS …. UNEXPECTED RESULTS

A NEW EQUIPMENT TO OFFER

THE PROBLEM

• Kidneys with polyquistosis are difficult to measure • Renal volume is needed for follow up • CT scan cannot be repeated

How can renal volume be estimated non invasively?

Ultra Sound Imaging

Used routinely by nephrologists Non ionizing Repeatable Affordable

But US imaging is

Usually only qualitative User dependant

Volume estimated by formula 2D image only for DICOM

Poor documentation for ECR

NEFROVOL

Parallel 2D images along main axis User to define boundaries in each 2D

Build a mesh Extrapolate at the ends

Count contained elements Use scale to estimate volume

Design

NEFROVOL

Tests of NEFROVOL

Report for ECR in

CDA format

NEFROVOL to monitor volume

• Not very precise • Repeatability tests pending • Only indicative volume •  Self reference of patient • Graph over months or years available

Difficulty with patient communication

• What if the volume is 3D printed ?

3D printer produced by:

Start up firm of Cochabamba, Bolivia

Support from the Bolivian:

Small Enterprise to intregrate NEFROVOL into IMPOVOL:

Start up firm of Montevideo, Uruguay

Design and Coordination

NEFROVOL is a project of nib in cooperation with Nephrology Department of Hospital de Clínicas:

Mauro Sitrin, Esteban Arrua, D.I. Luciana Urruty, Dr. Oscar Noboa, Dr. Diego Tobal e Ing. Franco Simini.

La Impresora 3D es un desarrollo de SAWERS, Cochabamba, en una iniciativa de cooperación de la Universidad Mayor San Simón de Bolivia y de la Universidad de la República.

La integración y distribución son de Bullseye, Montevideo. Setiembre 2014.

IMPOVOL

•  It is a new idea • Give a PVC model of an inner organ to

MDs for interaction with patients, not just a standard organ

• Give a real reproduction of organs for surgery planning, instruction, strategic decisions, reconstruction, tc

By product

DICOM new object type: CT-like set of images for US

specifying number of cuts

What do you think of it?

Thank you !
