Cryoablation of the prostate using 17-gauge IceRod cryoneedles is closely examined in this case study video. The patient is a 72-year-old male who has been diagnosed with clinical stage T1C prostate cancer with a 7 Gleason score. A doctor at Allegheny General Hospital in Pittsburgh, PA guides viewers through the steps involved in the procedure. The video starts by measuring the patient’s prostate gland and then uses a brachytherapy template with ultrasound for probe placement. During the procedure, a total of two freeze-thaw cycles are performed.
Prostate Animation
This animation shows a 3D model of a male patient in the lithotomy position undergoing a cryotherapy as primary or salvage prostate cancer treatment. The procedure uses a stepping device to hold transrectal ultrasound probes and 17-gauge cryoablation needles; software to confirm placement of the needles and simulate the freezing effect of the configuration; and real-time ultrasound imaging to show actual placement of cryoneedles and monitor temperatures in the precision freeze zone.
IceRod™ Iceball
The IceRod™ consists of a 17-gauge cryoneedle and an advanced heat exchanger which produces a precise ice ball that is comparable in size to larger diameter cryoprobes. This video demonstrates iceball formation from 32mm x 56mm at 0˚C to 14.5mm x 34mm at -40˚C.
WRAL News Prostate News Report
On this nightly new program, reporters explain how surgeons in Durham County, North Carolina are using subzero temperatures through a procedure known as cryotherapy as a new and effective way to treat prostate cancer. The camera crew follows Thomas J. Polascik, M.D., a physician at Duke Medicine, into the operation room for a closer look at the procedure. Interviews with both Doctor Polascik and one of his patients reveal this treatment’s effectiveness.
Cellular Destruction with Cryosurgery
This educational video discusses the components of the freeze-thaw cycle as they relate to cellular destruction. Extracellular freezing dehydrates a cell, intracellular freezing destroys the cell internally, and warming effects facilitate the rupture of the cell membrane. This rapid freeze-thaw cycle is shown under microscopic view.
Percutaneous Renal Cryoablation
This case study video depicts a contemporary technique for percutaneous cryoablation of a small renal mass. A 39-year-old male patient positions himself on the CT gantry and remains alert for the procedure. A targeting template is placed on his flank, marked, and the area is prepped. An access sheath is deployed and a needle biopsy is performed. Cryoablation probes are positioned using CT scans and a dual freeze-thaw cycle is deployed. The patient is interviewed post operatively on his experiences before, during, and after the procedure.
Cryoablation of the Prostate using Cryoneedles
Cryoablation of the prostate using ultra-thin, 17-gauge cryoprobes is closely examined in this case study video. The patient is a 72-year-old male who has been diagnosed with clinical stage T2A prostate cancer with a 7 Gleason score. Dr. Ralph Miller of Allegheny General Hospital in Pittsburgh, PA guides viewers through the steps involved in the procedure. The video starts by measuring the patient’s prostate gland and then uses a template to position a series of 17-gauge cryoprobes. During the procedure, a total of four – two at the base and two at the apex – freeze-thaw cycles are performed.
Kidney Animation
To show what cannot be seen with the human eye, this kidney animation demonstrates what is involved in a renal cryoablation procedure using ultra-thin, 17-gauge cryoablation needles. The needles are inserted percutaneously under laparoscopic visualization and guided into position with real-time ultrasound, CT, and MRI imagery. Thermal sensors are inserted to monitor temperatures during the procedure and prevent damage to healthy tissue. Two freeze-thaw cycles are performed and the benefits of cryoablation are discussed.
Kidney Renal Cryoablation
This case study video demonstrates a kidney renal cryoablation treatment as performed by Dr. Jamie Landman of the Columbia University Medical Center for a 62 year old male patient. A combination of CT scans and laparoscopic imaging is used to locate and characterize the patient’s renal mass while narration explains how and why the actions are performed. Cryoablation needles are inserted and two freeze-thaw cycles are initiated under a clear and close-up laparoscopic view. The patient recovered uneventfully and follow-up CT scans reveal that the area of the tumor was non-invasive.
CT Guided Renal Cryoablation
On-location video captures a CT-guided percutaneous renal cryoablation procedure as its being performed external to the patient. The female patient is transported to the CT room where a grid is placed on her skin, a CT image is taken, and the skin is marked to identify the kidney location. A biopsy is taken, and three cryoablation needles are inserted at which point two freeze-thaw cycles are performed. After the second cycle ends and the needles are removed, the patient is transported to Recovery.
IceSeed™ Iceball
The IceSeed™ 17-gauge cryoablation needle creates a small, round-shaped iceball for targeting small tumors. This video demonstrates IceSeed™ iceball formation.
WGN News Kidney News Report
In this nightly Medical Watch news program in Chicago the focus is on cryotherapy as a potentially beneficial cancer treatment option particularly for elderly patients. Practicing urology in Blue Island and Evergreen Park, Illinois, Dr. James Sylora is interviewed and briefly explains the treatment procedure. The program also includes a patient interview and discusses what makes for a good candidate. At the conclusion, the medical/health reporter makes note of benefits and risks to consider.
Renal Cryoablation
Doctor Arie S. Belldegrun, Chief of the Division of Urologic Oncology and Director of Urologic Research in the Department of Urology at the University of California, Low Angeles, discusses innovative therapies for renal cell carcinoma. The therapeutic options covered in this video include, partial and radical nephrectomy; and tumor ablation by way of cryoablation, radiofrequency ablation (RFA), and high intensity focused ultrasound (HIFU). The video goes into the operating rooms and demonstrates how these options are performed using different techniques and provides a visual comparison between the procedures.
Prostate Cryoablation Overview
Doctor Arie S. Belldegrun provides a brief prostate cryoablation overview and introduces the demonstration of a typical case using the Galil Medical SeedNet™ system. He and his colleagues at the UCLA School of Medicine, doctors Amnon Zisman and Allan J. Pantuck, and doctor Jeffery K. Cohen of Allegheny General Hospital in Pennsylvania are filmed performing the procedure. The video covers the entire process, starting with set up, cryo probe placement, SPC insertion, and urethral warmer placement through two freeze-thaw cycles and completion.
