Primary outcomes included the change in stricture quality and the difference in ureteral stricture length after ureteral rest. Results: Overall, 50 patients met the inclusion criteria. Preoperative stricture quality was determined to be narrowed in 86.0% and obliterative in 14.0% of patients.

Based on these findings, we sought to simplify the existing ureteral injury grades and improve ureteral stricture prognostication by creating a novel dichotomous injury scale. Conclusions: Iatrogenic ureteral stricture rates rose sharply when ureteral wall integrity was disrupted.

Considering the reduced quality of life due to the nephrostomy and the possibility of ureteral stricture due to malignancy, the patient underwent right nephrectomy at a later date. Pathological examination revealed an abscess and granuloma around the ureteral stenosis....Therefore, the patient was diagnosed with ureteral stricture due to syphilis.
Comparison of different segmental metal ureteral stents as maintenance therapy across different years in ureteral stricture management: a systematic review and meta-analysis [0.03%]

Background: Ureteral stent placement is a common treatment for relieving hydronephrosis due to ureteral strictures. Recently, segmental metal ureteral stents (MUSs) have emerged as a promising option. However, the efficac...
The clinical efficacy analysis of One-stage flexible ureteroscopic lithotripsy assisted by CT urography and intelligent pressure control platform and the establishment of a prediction model for stone clearance rate [0.03%]

After identifying the independent risk factors through Logistic regression analysis, the clinical prediction model for the SFR was established as follows: L = ureteral stricture + 1.288/1.144 × urinary tract infection + 1.315/1.144 × CT value of the stone + 1.154/1.144 × IPA angle + 4.989/1.144 × stone...The areas under the ROC curve were as follows: combined predictor (0.913) > stone volume (0.895) > stone composition (0.639) > IPA angle (0.627) > ureteral stricture (0.609) > urinary tract infection (0.595).

Secondary outcomes included the total SFRs 1 month postoperatively, operative time, reduction in hemoglobin levels, length of postoperative hospital stay, improvement in the quality of life as measured by the QoL score, incidence of ureteral stricture at 3 months postoperatively, and any surgery-related...At 3 months postoperatively, the difference between two groups in the terms of ureteral stricture was not statistically significant (P > 0.05). Notablely, the overall rate of postoperative complications was markedly lower in the FV-UAS group than in the MPCNL group (P < 0.001).

Objective: A porcine model was established to investigate the effect of indwelling duration of ureteral stents on formation and pathological characteristics of ureteral stricture after laser thermal injury....The incidence of ureteral stricture in group A was higher than that in group B (P < 0.001). The percentages of inflammatory cell infiltration (P = 0.001), epithelial necrosis (P < 0.001), and epithelial hyperplasia (P < 0.001) were higher in Group A than in Group B.

Drawing parallels with ureteral stricture prevention, where prestenting with a ureteral catheter is commonly used, we hypothesize that preoperative transurethral catheterization may relax and dilate the urethra, potentially lowering the risk of stricture formation.

Methods: A prospective, multicenter, randomized, open-label, and controlled study enrolled 60 ureteral calculi patients with ureteral stricture from July 2021 to July 2023.

Therefore, in this study, we established a rabbit ureteral stricture model, implanted a ureteral stent loaded with TGF-β1-siRNA for treatment, and compared the histopathology of ureteral stricture and the protein expression of genes related to the formation of stricture between different groups to test...In addition, the rabbit ureteral stricture model experiment verified that TGF-β1-siRNA could effectively transfect into ureteral tissues and inhibit the expression of TGF-β1, thereby inhibiting ureteral stricture.
