A rare case of spondylodiscitis.
IDCases
December 2024
Division of Infectious Diseases, Department of Medicine, University of Kansas, Kanas City, KS, USA.
A 55-year-old-male with a chronic left uretero-pelvic junction (UPJ) obstruction managed with intermittent stent exchanges presented with low midline back pain. CT Abdomen/Pelvis revealed spondylodiscitis at L4-L5, further demonstrated on MRI Lumbar spine. Imaging also revealed the left nephro-ureteral stent was mispositioned, with some mild wall thickening of the left ureter.

Objective: To determine whether adjuvant transforming growth factor-β (TGF-β) inhibition with pirfenidone (PFD) can mitigate ureteral wall scarring and related complications in a rat model of upper urinary tract ablation with irreversible electroporation (IRE).
Methods: Transmural ablation of the ureter was performed with IRE in 24 rats. Post-IRE, animals were randomly assigned to receive PFD or no drug, followed by euthanasia at 2-, 5-, or 10-days.
Prospective Evaluation of Ureteral Wall Thickness as a Means to Predict Spontaneous Stone Passage: Is It Beneficial?

Department of Urology, University of California Irvine, Orange, California, USA.
Ureteral wall thickness (UWT) was proposed as a potential predictor for spontaneous stone passage (SSP). In earlier studies, the effect could not be isolated from stone size. Accordingly, we sought to determine whether UWT, alone or combined with stone size, could enhance SSP predictability.

Purpose: The objective of this study was to evaluate the diagnostic efficacy of high- and low-frequency ultrasound (H&LFUS) in the imaging of post-hematopoietic stem cell transplantation (post-HSCT) ureteral obstruction in leukemia patients.
Methods: A total of 103 patients who received HSCT for leukemia were included in this retrospective study. Patients underwent examinations using high-frequency ultrasound (HFUS), low-frequency ultrasound (LFUS), and the combined use of H&LFUS approach.

Article Synopsis
- * In the experiment, urine was either aspirated from the bladder or leaked through the ureter into the peritoneum of seven minipigs, with samples taken at 4 and 10 hours for analysis of inflammatory response.
- * Results show that while urine in the peritoneum causes bowel distention, there was no significant inflammatory response in the visceral peritoneum within the 10-hour observation period, leading to questions about other mechanisms affecting bowel distention.
