Background And Objective:
Ileal ureter replacement (IUR) is the definitive management approach for extensive ureteral strictures (UrSs). Patients with UrS exhibit poor health-related quality of life (HRQoL). We conducted a long-term, multi-institutional evaluation of patients who underwent IUR to assess its durable safety and efficacy, as well as postoperative recovery of HRQoL.
Methods:
A prospective multicenter study (January 2020-July 2022) enrolled patients with an extensive UrS scheduled for IUR. Participants completed the 36-item Short Form Survey (SF-36) before and at 6 mo and 12 mo after surgery. A significant HRQoL improvement was defined as an increase of ≥10 points from baseline.
Key Findings And Limitations:
Overall, 82 consecutive patients who underwent IUR were evaluated. The mean age of the cohort was 44.6 yr, and 52/82 (63.4%) were female. During median follow-up of 48 mo, one patient experienced radiographic reobstruction, and eight patients had Clavien-Dindo grade III-IV complications. There was a significant decrease in serum creatinine after surgery (p < 0.001), with a minor increase observed at long-term follow-up (p = 0.001). Some 45.5-79.2% of patients with poor HRQoL at baseline experienced significant improvements in different domains within 12 mo after surgery. Specifically, in comparison to baseline, 77 patients (93.9%) reported improvements at 6 mo (median improvements: physical function [PF] +15; role limitation due to physical health [RP] +87.5; bodily pain [BP] +10; general health perception [GH] +16; vitality [VT] +20; social function [SF] +25; role limitation due to emotional problems [RE] +100; mental health [MH] +12), and 79 (96.3%) reported improvements at 12 mo (PF +20; RP +100; BP +20; GH +18.5; VT +20; SF +25; RE +100; MH +12). The main limitations are the lack of a disease-specific questionnaire and the relatively short-term follow-up for HRQoL.
Conclusions And Clinical Implications:
Our study confirms the safety and efficacy of IUR for complex ureteral reconstruction. IUR was associated with favorable HRQoL improvements within 12 mo in most domains.
Patient Summary:
We looked at changes in quality of life for patients who had surgery that used a piece of bowel tissue to repair a complex urinary blockage. Most patients reported a substantial improvement in their quality of life within 12 months. Our findings support use of this surgical procedure as an effective option when simpler treatments fail.

Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
