Nephroureterectomy with ileal cuff for upper tract recurrence after radical cystectomy: oncologic and survival outcomes.
Article in World journal of urology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeUpper tract urothelial carcinoma developing after radical cystectomy presents a technical challenge because complete ureteral removal to the ileal anastomosis is often hindered by postoperative adhesions. This study evaluated the prognostic impact of the completeness of ureteral excision including the ileal cuff in patients undergoing nephroureterectomy for upper tract recurrence after radical cystectomy.
methodsWe retrospectively analyzed 30 patients who underwent nephroureterectomy for recurrent upper tract urothelial carcinoma after radical cystectomy between 2001 and 2024. Patients were divided into the Cuff group (complete ureteral excision including the ileal cuff, n = 18) and the Cuff_Fail group (failed or omitted distal excision, n = 12). Survival outcomes were compared using Kaplan-Meier analysis, and Firth's penalized Cox regression was applied to adjust for small-sample bias.
resultsAmong 2,148 patients who underwent radical cystectomy, 30 (1.4%) later required nephroureterectomy for upper tract recurrence after a median interval of 49 months. The 5-year cancer-specific survival rate was significantly higher in the Cuff group than in the Cuff_Fail group (74.3% versus 30.6%, p = 0.013). Multivariate analysis identified incomplete ureteral removal as an independent predictor of poorer cancer-specific survival (hazard ratio 3.41; 95% confidence interval 1.09-12.32; p = 0.035).
conclusionIn nephroureterectomy for upper tract recurrence after radical cystectomy, complete ileal cuff excision was associated with improved cancer-specific survival. These hypothesis-generating findings require validation in larger multi-center cohorts.
