BACKGROUND AND PURPOSE Cone beam CT (CBCT) is a novel imaging modality that combines the versatility of conventional C-arm imaging with the functionality of cross-sectional imaging. This is a pilot study to evaluate the capabilities of this new technology to obtain percutaneous access and for the immediate postoperative evaluation of residual fragments in(More)
UNLABELLED What's known on the subject? and What does the study add? Pathological stage, lymph node metastasis and tumour grade have been established as prognostic factors for upper-tract urothelial carcinoma, but there are few studies to date assessing location within the ureter as a prognostic factor. There are also few studies comparing surgical(More)
The presence of direct current (DC) injury currents in ischemic tissue is an important diagnostic indicator of pathophysiology in cortical spreading depression and particularly in myocardial infarction. To date, no measurements of DC injury currents in the alimentary tract have been reported. We used a SQUID magnetometer to measure changes in the baseline(More)
UNLABELLED What's known on the subject? and What does the study add? With the advancement of minimally invasive surgery, the management of small renal masses (SRM) has dramatically changed. Ablative technology such as radiofrequency ablation (RFA) and cryoablation have emerged as viable alternative modalities to extirpative surgery. RFA is one of the most(More)
Prostate cancer remains the most common solid organ malignancy in men. Unfortunately, surgical management of this disease is often associated with significant morbidity. In an effort to decrease the invasiveness and deleterious impact on quality of life associated with prostate cancer surgery, minimally invasive techniques have been applied to this disease.(More)
Testicular cancer is the most common solid organ malignancy in young men between the ages of 15 and 35. Although much of this increase in survival can be attributed to improvements in systemic chemotherapy, surgery retains a critical role in the diagnostic and therapeutic management of testicular cancer. Laparoscopic retroperitoneal lymph node dissection is(More)
approach, the answer is no. so how can we position pazopanib among the existing treatment options? in reality, it is difficult to find a niche for this molecule, despite its promising PFs, excellent response rate (32% in treatment-naive patients) and good tolerability profile. as such, pazopanib’s place might be in third, fourth or even subsequent treatment(More)
