A visual computer tool for percutaneous nephrolithotomy preoperative planning

Proceedings of the 25th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (IEEE Cat. No.03CH37439), 2003

The percutaneous nephrolithotomy is a minimally invasive surgery that is employed to remove larger stones (calculi) in the kidney. This technique places a nephroscope into the kidney through a small tract set after a small incision in the patients back. During the tract positioning, there are risks of kidney bleeding and of injury of other organs near the kidney such ...

  • A visual computer tool for percutaneous nephrolithotomy preoperative planning

    The percutaneous nephrolithotomy is a minimally invasive surgery that is employed to remove larger stones (calculi) in the kidney. This technique places a nephroscope into the kidney through a small tract set after a small incision in the patients back. During the tract positioning, there are risks of kidney bleeding and of injury of other organs near the kidney such as the bowels, spleen or lever. In order to minimize this risks a preoperative planning helps for the choice of the best kidney calyx target and for the definition of the optimal track to reach this target. Our study is focused on the development of a computer tool that will help establishing the preoperative planning on patient specific data. Especially, this tool allows defining interactively and visually the optimal track on a 3D volume data acquired on the patient, simulating the effect on the anatomy of the real passageway and finally gives the necessary information back to the surgeon in order to transpose during the intervention the defined optimal track.

  • Shock wave pulse pressure after penetration of kidney tissue

    Lithotripter generated compressional peak pressure (p/sup +/) was measured after penetrating tissue samples 0.5, 1, 2.5, and 4 cm thick. The samples were taken from fresh pig kidneys and insonated by shock wave pulses with positive peak pressures varying from 14 to 72 MPa. The measurement results allow one to draw some qualitative conclusions concerning the attenuation process in the lithotripter beam and show that in practice the compressional peak pressure values generated in the lithotripter may decrease almost by a factor of two before reaching the kidney stone. On the contrary, theoretical estimates indicate that negative pressures are practically not influenced by attenuation due to their different spectral composition.<<ETX>>

  • Shockwave simulation in electrohydrolic lithotripsy and wave performance optimization

    Lithotripsy systems are commonly used to break kidney stones into fragments. Nowadays these systems are also used in orthopedic operations. There are several ongoing investigational studies on lithotripsy systems in the treatment of cancer and cardiovascular diseases. Because of these new application areas we need novel lithotripter designs for different kinds of treatment strategies. The best way to reduce design time and cost is to create a computational model of the lithotripsy system. In this study the finite difference time domain (FDTD) method were used while constructing the computational model of the lithotripsy system. While implementing the model, most of the physical system parameters were defined as an input and/or as a variable in the simulations. We tested several realistic parameters used in the simulations and compared the results with the expected outcomes and optimized our system accordingly. Finally, we studied the effects of changing the input parameters like ellipsoide reflector size, and focus point misalignment. In conclusion, to reduce design costs in various medical applications that use shockwave principle this computer-based simulation platform may be suitable.

  • Modification of the design of the invasive lithotripter sheath for effective urinary calculi disintegration

    Human urinary calculi is still a major problem facing urologists and scientists. Besides the standard surgical removal it has been shown that these stones can be removed by non-surgical disintegration using invasive or non- invasive techniques. This paper describes an in-vitro experiment performed to study the effect of a modification introduced to the design of the sheath being used with the electrohydraulic lithotripter (EHL). The details of the design will not be discussed here, however, various parameters, namely, spark duration, the standoff distance between the electrode tip and the urinary test concretions, and the repetition rate of the electrical discharge, were examined in this experiment. It was shown that the modification not only can eliminate the EHL sources of deficiency but it can make the technique more versatile and effective, particularly for removing ureteric calculi.

  • Regression Analysis for the Climate Effects on Seasonal Variations in the Urinary Lithotripsy: A Regional Hospital Based Study

    We study the climate effects on seasonal variations in the amount of urinary lithotripsy operations using 6-year data in a regional hospital in northwestern Taiwan. From 2003 to 2008, 7660 procedures for upper tract urinary calculi are performed. These data are divided into subgroups by gender and age range (18-44, 44-65, &gt;65). Five climate factors (ambient temperature, atmosphere pressure, relative humidity, hours of sunshine, and rainfall) are considered. The purpose of this study is for used in the future research aiming to predict the stone recurrence based on climate conditions and related items for this hospital. Unlike an earlier nationwide study, our results show that not only the ambient temperature but also the atmosphere pressure and relative humidity have significant effects on the amount of urinary lithotripsy operations. The difference may be due to the multicollinearity problem. Furthermore, we exclude the age group of 65 and older from the regression analysis because of its lack of seasonal variations.

  • Cavitation induced cell detachment and membrane permeabilization

    The effects of cavitation bubble dynamics on cells has been investigated with respect to cell damage, cell detachment and membrane permeabilization. High- speed images show the dynamics of pressure excited contrast agents and of lithotripter generated cavitation bubbles adjacent to cells. It is shown that cells are detached from a substrate by the action of cavitation bubbles. Furthermore, fluorescence labeling techniques indicate destruction and transient permeabilization of cell membranes after cavitation activity conterminous to the sites of cell detachment.

  • Ultrasonic probes for shock wave measurements

    Extracorporeal shock wave lithotripsy (ESWL) has recently become the preferred procedure for the treatment of urinary and gall bladder stones. The device used in this treatment generates acoustic shock waves which are focused onto the stone, causing it to disintegrate. Interest in studying the properties of the shock waves quantitatively has intensified, since it is believed that the acoustic shock wave parameters, such as rise time, peak positive and peak negative pressure amplitudes, and frequency content, may influence the treatment's efficiency. In the present work the authors describe the evaluation of several piezoelectric materials and design configurations for their applicability to quantitative shock wave measurement. Preliminary experimental results indicate that PVDF (polyvinylidene fluoride) polymer sensors with a low acoustic impedance backing have the greatest potential as shock wave sensors.<<ETX>>

  • Dependence of the ultrasonic nonlinearity parameter B/A on cellular-level structure

    The nonlinearity parameter B/A of biological media is considered useful as a tissue characterization parameter and as an accurate model of finite amplitude wave propagation in such applications as ultrasonic hyperthermia and lithotripsy. The dependence of B/A on cellular-level structure has been investigated by the thermodynamic method using liposomes as a cell model. B/A measurements were made using a pressure jump scheme to create an adiabatic pressure change and employing a cross-correlation method to determine the time delay between a pulse transmitted through a sample and a reference pulse and, thereby, the speed of wave propagation. It was found that B/A increases considerably near the transition temperature of the liposomes, suggesting that the nonlinearity parameter reflects the state of the liposome membrane.<<ETX>>
