Purpose: To illustrate a simple method that screens for ureteral injury in the acute postoperative period after urogynecologic surgeries.
Methods: Serum creatinine measurements in the preoperative (baseline) and postoperative periods of urogynecologic surgeries were determined and the correlation of the change to ureteral injury and/or obstruction analyzed. The sample size calculation showed 7 cases and 28 controls were sufficient to detect significant changes in creatinine. Each of the seven cases was matched for age and type of surgery with a control patient in a 1:4 ratio following standard protocol.
Results: Chart review of patients (273 cases) undergoing urogynecologic surgeries from October 2009 to June 2014 were undertaken. There were 7 cases of ureteral injury and 28 matching control cases. All cases had intraoperative cystoscopy confirming bilateral ureteral flow. In the ureteral injury group, blockage of ureter was confirmed by CT scan with IV contrast. There was a 59.8% increase in serum creatinine levels postoperative in the ureteral injury group versus a 3.8% decrease in controls. A difference of creatinine levels greater than or equal to 0.3 mg/dL over baseline was evident in ureteral injury cases.
Conclusion: A small change in serum creatinine level over baseline after urogynecologic surgery alerted the possibility of ureteral injury or obstruction. A simple and inexpensive evaluation of perioperative creatinine levels can promptly diagnose ureteral damage in the acute postoperative period for gynecologic reconstructive surgeries.

Renal fibrosis is a common pathological process in various chronic kidney diseases. The accumulation of senescent renal tubular epithelial cells (TECs) in renal tissues plays an important role in the development of renal fibrosis. Eliminating senescent TECs has been proven to effectively reduce renal fibrosis.

In our research, we constructed models of renal ischemia-reperfusion (I/R)-exposed acute kidney injury (AKI) and unilateral ureteral obstruction (UUO)-stimulated renal fibrosis (RF) in C57BL/6 mice and HK-2 cells. We firstly authenticated that oral pinocembrin (PIN) administration obviously mitigated tissue damage and renal dysfunction induced by I/R injury, and PIN attenuated UUO-caused RF, as confirmed by the reduced expression of fibrotic markers as well as hematoxylin-eosin (H&E), Sirius red, immunohistochemistry, and Masson staining. Meanwhile, the beneficial role of PIN was again demonstrated in HK-2 cells with hypoxia-reoxygenation (H/R) or transforming growth factor beta-1 (TGF-β1) treatment.

Objectives: Serum galectin-3 (sGal-3) is a protein present in renal tubules and increases in experimental rodent models of acute kidney injury. The aim of this study was to compare sGal-3 concentrations in healthy cats and cats with ureteral obstruction (UO).
Methods: This was a retrospective study.

Spontaneous ureteral rupture is a rare cause of acute abdominal pain, particularly unusual during pregnancy or the post-partum period. While pregnancy-related changes like ureteral compression and dilation may play a role, no definitive mechanisms have been established. Clinicians should suspect ureteric injury in post-partum patients with free pelvic fluid.

Introduction: The pathogenesis of renal fibrosis is related to blood stasis, and the method of promoting blood circulation and removing blood stasis is often used as the treatment principle. Danshen injection (DSI) is a commonly used drug for promoting blood circulation and removing blood stasis in clinic. However, whether DSI slows the progression of renal fibrosis or the potential mechanism is uncertain.
