Renal angle: B/W 12th rib & Erector Spinae Anatomy, Medical, Medical Doctor Areas/Organs - Urinary tract - Kidneys Relationships Kidney Anatomy. Attempt to ballot the kidney with the other hand in costophrenic angle. An enlarged kidney should be palpable by the anterior hand. Repeat the same maneuver. Jun Date of Web Publication, Jun Laparoscopic or robotic surgery is the main method of treating renal cell carcinoma (RCC). LUS can assist in the detection of tumor boundaries and the extent of tumor thrombi. The lack of .. The robotic US probe angle can be adjusted with the robotic instrument.
renal angle - definition and meaning
After renal artery division, the proximal renal vein was found to be flat because of a lack of blood flow, which allowed easy visual identification of the proximal extent of the tumor thrombus. The renal vein and vena cava were dissected to allow a 1—2 cm margin distal to the thrombus.
renal angle - Wiktionary
An endovascular stapler was used to staple the renal artery, and then the stapler was guided to the uninvolved portion of the renal vein using LUS. When the thrombus extends into the IVC and cannot be milked back, vascular staplers are ineffective; thus, vascular clamps are necessary to control the IVC distally and proximally.
Demarcation of the thrombus with LUS is useful in delineating the extent of necessary IVC dissection during the initial laparoscopic part of the procedure. Further refinement and investigation of this technique may be necessary to optimize results in human patients and is currently underway.
Laparoscopic Ultrasound Contrast-enhanced ultrasound CEUS is an advanced technique that utilizes US contrast agents to improve lesion visualization in difficult cases. This oscillation produces energy that is detected by the transducer and converted into an image.
As an effective diagnostic modality, this method leads to better, enhanced scanning of the macro and microvasculature of the kidneys.
Costovertebral angle tenderness
However, the higher US transmission power may result in microbubble destruction. Renal US can assess disseminated tissue disorders, focal lesions, and renal perfusion. CEUS is not affected by movement artifacts caused by the US probe and may, therefore, be a better technique than the power Doppler. As the malignant tumor is rich in blood supply, this feature improves the quality of the CEUS detection signal compared to other ultrasonographic methods such as power Doppler.5 Christian Dating Boundaries
The combination of selective occlusion angiography and CEUS provides a more effective assessment of renal ischemia and of the perfusion area. In the case of reduced renal perfusion, ischemia, and diabetic nephropathy, under-intake is safely overcome by multiple injections. LUS probes for intraoperative scanning have limitations and may reduce surgical precision, as the assistant holds and manipulates the LUS probe.
The LUS probe is also prone to slipping off the kidney surface and requires the assistance of a robotic instrument for repositioning the probe or to prevent it from slipping off the kidney. It can be especially challenging with tumors in a posterolateral or upper pole location. Challenging angles for US include the near and far edges of the tumor, in which the angulation of the LUS probe may make it difficult to place the probe flat on the kidney surface parallel to the tumor edge without extra mobilization of the kidney.
The robotic US probe angle can be adjusted with the robotic instrument.
The robotic US probe also eliminates the issue of instrument clashing in the operating field. According to all published medical literature, there are so far only four cases including the patient reported here.
And each of the four cases showed its own characteristics, which will be discussed below Case report A year-old male patient suffered from abdominal pain and abdominal distension for half a month.

A large abdominal mass was noted on the left abdomen without clear causes. After seven days, the symptoms were aggravated and the abdominal mass become bigger prior to his admission to the hospital on July 14th On body examination, the patient was found to experience left abdominal dilation, and a large, solid abdominal mass extended from the left side of the rib arch to the symphysis pubis. The top was located on the costal margin, the bottom in pelvic cavity, dotted inside, and separated into many parts.
Left kidney is Abdominal enhanced computed tomography CT: Peripheral vascular and organ changed location under pressure. The strengthened reinforcement is not obvious, with mild delay to strengthen.
It may be because of the left kidney intra-fascial placeholders and liposarcoma gets the highest possibility Figure 1A. Kidney ECT showed that left kidney moved up and shrank, no abnormality was observed in blood perfusion, renal parenchymal damage, or delayed excretion.
