“…The evaluation of urinary tract obstruction and ureterolithiasis by imaging methods has been the subject of a series of recent publications in the radiology literature of Brazil (15)(16)(17)(18) . The present study provides evidence of the value of applying methods of cost-effectiveness analysis to interventional radiology.…”

Objective: To compare two percutaneous techniques used in the treatment of malignant obstructive uropathy-antegrade double-J stent placement (JJ stenting) and percutaneous nephrostomy-in terms of their cost-effectiveness, from the perspective of the Brazilian public health care system. Materials and Methods: In this cost-effectiveness analysis, we employed decision-analytic modeling. We calculated material costs from 2017 factory prices listed by the Brazilian Pharmaceutical Market Regulatory Board (for medications) and published in the journal Revista Simpro (for medical devices). Procedure-related costs were evaluated, as were the rates of technical and clinical success. Those measures were then used as inputs for a cost-effectiveness analysis comparing the two procedures. Results: The sample comprised 41 patients, of whom 16 underwent antegrade JJ stenting (26 procedures) and 10 underwent percutaneous nephrostomy (15 procedures). Patient records, radiology reports, and expense reports of the interventional radiology department of the public hospital where the study was conducted were analyzed retrospectively. There were no significant complications: one patient had low back pain, and one had a transient retroperitoneal hematoma. The mean procedure time was 24 min, and clinical success (improvement in serum creatinine and resolution of hydronephrosis) was achieved in 97.5% of the cases. The average cost of JJ stenting was significantly lower than was that of percutaneous nephrostomy (US$164.10 vs. US$552.20). Conclusion: In the absence of any clinical contraindications, antegrade JJ stenting is a suitable alternative to both percutaneous nephrostomy and retrograde stenting in patients with dilated renal collecting systems secondary to malignant ureteral obstruction, providing significant cost savings and high success rates.

“…Voiding can reduce the possibility of patient motion from discomfort or needing to terminate the study prematurely for the patient to urinate. It also minimizes the backpressure effect that a distended bladder may have on slowing the draining of the upper tracts (16)(17)(18)(19).…”

Twist and shout: magnetic resonance imaging findings in ovarian torsion

et al. 2019

Adnexal torsion is characterized by partial or complete rotation of the suspensory ligament of the ovary and its corresponding vascular pedicle, resulting in vascular impairment that can culminate in hemorrhagic infarction, as well as necrosis of the ovary and fallopian tube. Because there are myriad causes of acute pelvic pain, the differential diagnosis of ovarian torsion is often challenging. Consequently, radiologists should be familiar with the main imaging findings. In this regard, there are typical signs of ovarian torsion on magnetic resonance imaging, including increased ovarian volume with stromal edema and peripheral distribution of the ovarian follicles, as well as thickening of the fallopian tube, an adnexal mass (causal factor) that shifts toward the midline, and the classic, pathognomonic “whirlpool sign”. The objective of this essay was to review and illustrate the various magnetic resonance imaging findings in ovarian torsion.
