The Impact of One Week of Pre-stenting on Porcine Ureteral Luminal Circumference.

J Endourol 2022 Jan 19. Epub 2022 Jan 19.

University of California Irvine, 8788, Urology, Orange, California, United States;

Percutaneous insertion of bilateral double J in pelvic cancer patients: Indications, complications, technique of antegrade ureteral stenting.

Gynecol Oncol Rep 2021 Nov 24;38:100864. Epub 2021 Sep 24.

Interventional Radiologist, Radiology Department, Heart Institute (InCor), University of São Paulo, São Paulo, Brazil.

Background: Antegrade percutaneous insertion of a double J seems to be a good alternative when retrograde insertion fails. Malignant ureteral obstruction occurs due to occlusion of the ureter secondary to tumor invasion, extrinsic compression, which prevents intermittent urine flow, leading to acute renal failure, increased morbidity, mortality and interruption of cancer treatment.

Case: A 26-year-old woman with endometrial carcinoma with internal invasion of pelvic structures due to urosepsis and acute renal failure. Read More
