Bladder tuberculosis with ureteral strictures after bacillus Calmette‑Guérin therapy for urinary bladder cancer: A case report.
Article in Molecular and clinical oncology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
Intravesical immunotherapy using bacillus Calmette-Guérin (BCG) is recommended for patients with intermediate- to high-risk non-muscle invasive bladder cancer. Bladder tuberculosis (TB) is a rare complication of BCG therapy. The present study describes the case of a 73-year-old man who underwent intravesical BCG therapy for urothelial carcinoma in situ of the bladder. Red patches around the resection scar were first detected 1 year and 5 months after BCG treatment; these findings gradually spread to encompass more of the bladder wall. Transurethral biopsy revealed a benign lesion, but the patient developed bilateral hydronephrosis and mild voiding dysfunction. The patient was eventually diagnosed with bladder TB by mycobacterial urine culture and TB-specific polymerase chain reaction (PCR). The patient was given multidrug therapy (isoniazid, rifampicin and ethambutol) and their bladder TB was completely cured; however, their voiding dysfunction and bilateral hydronephrosis did not fully improve. Bladder TB can occur long after intravesical BCG administration and cystoscopy findings consistent with inflammation can be the key to suspecting this condition. Acid-fast examination and PCR testing of a urine sample are necessary for early diagnosis.
