When disease travels downstream: The effect of intravesical recurrences in patients treated for upper tract urothelial carcinoma.

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
Background: Treatment of upper tract urothelial carcinoma (UTUC) depends on risk stratification and tumour characteristics. Kidney-sparing surgery (KSS) is preferred for low-risk disease, whereas radical nephroureterectomy (RNU) is the standard for high-risk UTUC. Intravesical recurrences (IVR) are common after both treatment modalities, but their impact on survival remains unclear. Objective: To assess the IVR rate and cumulative hazard following UTUC treatment and oncological outcomes based on the presence of IVR during follow-up. Second, the relation between UTUC and IVR tumour grade in patients treated with endoscopic KSS (eKSS). Methods: A single-centre study, including non-metastatic UTUC patients treated between 2010 and 2023. Analysis was performed in a cohort of patients without a history of bladder cancer. Results: In total 164 patients were selected; 85 treated with eKSS, 79 by RNU. Overall, 91 patients (55%) developed an IVR, 53 (62%) after eKSS and 38 (48%) after RNU, during a median follow-up of 33 months (IQR 11-72). eKSS-treated patients showed a significantly higher cumulative hazard for IVR (HR 0.6, 95% CI 0.42-0.95, Conclusions: Patients treated by eKSS showed a higher cumulative hazard of IVR, without an impact on oncological outcomes. These findings support the use of kidney-sparing approaches in well-selected cases and highlight the need for proper follow-up including the bladder and evaluate IVR preventive measures as intravesical instillations.
