Summary
Advanced imaging modalities, including 3D models and CAD, offer valuable insights during complex kidney surgery, potentially aiding navigation and visualization more than 3D prints alone.
Area of Science:
- Urology
- Medical Imaging
- Surgical Technology
Background:
- Advanced 3D imaging and 3D printing are increasingly used but lack comprehensive surgical comparison.
- Complex renal surgeries require precise visualization and navigation.
Observation:
- A patient with a complex horseshoe kidney and stones underwent evaluation using five imaging modalities derived from CT data.
- These included a 3D printed model, three volume rendered models, and a CAD model.
- A survey assessed modality effectiveness during laparoscopic surgery phases.
Findings:
- CAD models, 3D prints, and various volume renders provided significant insights during complex kidney surgery.
- CAD manual segmentation enhanced visualization of tissue layers and abnormal vasculature.
- 3D printing facilitated simultaneous visualization of the renal pelvis and surrounding vasculature.
Implications:
- Advanced imaging modalities can effectively complement intraoperative CT data and laparoscopic displays.
- Specific modalities may offer greater intraoperative benefit than 3D printed models, depending on the surgical step.
- Factors for evaluating advanced imaging in complex surgery are presented.

01:28Imaging Studies I: Kidney, Ureter, and Bladder Studies
382
Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

01:30Types of Building Stone
464
Building stones, essential materials for construction, are extracted from natural rock deposits and processed into specific forms and dimensions suitable for various building applications. These stones are broadly classified into three types based on their geological formation: igneous, sedimentary, and metamorphic.
Igneous rocks are formed from the solidification of magma or lava. An example is granite, known for its durability and resistance to weathering, making it ideal for parts of...

01:15Quarrying of Stone
601
Quarrying is the process of extracting stone from a quarry, where specialized techniques are employed to remove large blocks of stone safely and efficiently. This process can involve controlled explosions or more precision-oriented methods such as cutting and drilling.
One common method involves using a diamond belt saw to cut large blocks from the quarry face. These blocks can be about 50 feet long and 12 feet high. After the initial vertical cut, drilling is performed at the base of the...

01:29Stone Masonry
510
Stone masonry is a construction technique that uses individual stones to build structures and can be categorized into two main types: rubble and ashlar. Rubble masonry uses uneven, naturally shaped stones such as river rocks or fragments from quarries. This method often requires the mason to select and possibly shape each stone to fit the designated space, ensuring a proper build, even with irregular stone sizes and shapes. Ashlar masonry, on the other hand, employs uniformly cut stones that...

01:21Pilot and Numeric Relaying
496
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

01:15Sensory Modalities
4.0K
Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...
