Lower urinary tract dysfunction in childhood cancer survivors - A prospective study in a tertiary care hospital.
Observational study in International urology and nephrology, 2026. 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
backgroundLower urinary tract dysfunction (LUTD) is a potential late effect in childhood cancer survivors, often overlooked in survivorship care. Neurotoxic chemotherapy, pelvic tumors, and radiation exposure may contribute to its development.
objectivesTo determine the prevalence and severity of LUTD in childhood cancer survivors and identify associated risk factors.
methodsA prospective observational study was conducted over six months among 92 childhood cancer survivors aged ≥ 5 years to 10 years. Participants were screened using the LUTD Scoring System (DVSS). A score ≥ 9 in males and ≥ 6 in females was considered diagnostic of LUTD. Clinical and treatment-related variables were extracted from medical records and analyzed for associations. Uroflowmetry and ultrasonography were performed in children with abnormal DVSS to further assess voiding pattern and bladder parameters.
resultsLUTD was identified in 20 of 92 participants (21.7%), with a higher prevalence in females (31.6%) compared to males (14.8%), though this difference was not statistically significant (p = 0.073). Significant associations were observed with pelvic tumors (p = 0.002; Φ = 0.394), pelvic irradiation (p < 0.001; Φ = 0.455), Vinca alkaloid use (p = 0.035; Φ = 0.307), and high cumulative alkylating agent dose (> 8000 mg/m
conclusionLUTD is prevalent among childhood cancer survivors, particularly those exposed to Vinka alkaloids and pelvic-directed therapies. Routine LUTD screening using DVSS should be integrated into long-term follow-up protocols for early detection and intervention.
