Effect of bladder volume on dose of exposure to dangerous organs and incidence of cystitis and enteritis in patients with cervical cancer after external radiotherapy.

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 and objective: This study looked into how bladder volume affected clinical outcomes in individuals with cervical cancer after external radiation therapy as well as the radiation dosage received by organs at risk. Methods: A retrospective cohort analysis was carried out on 142 patients with cervical cancer who underwent postoperative radiotherapy between January 2017 and September 2020. Based on differences in bladder capacities, these patients were divided into three groups: Group A (V ≤ 300 ml), Group B (300<V ≤ 500 ml), and Group C (V>500 ml). The purpose of the study was to determine how different bladder volumes affected the radiation doses that the rectum (V30, V40, V50, D2cm Key findings and limitations: The median age was 53 years, and the usual follow-up period was 48 months. Group A had considerably higher values for bladder V30 and V40 (73.83 ± 11.56% and 47.21 ± 6.953%, respectively; Conclusions and clinical implications: For patients with cervical cancer undergoing external irradiation, a bladder volume of 300ml to 500ml is ideal. Advancing practice what does the study add?: This study identifies an optimal bladder volume range of 300-500 mL during external beam radiotherapy for cervical cancer. Compared to smaller or larger volumes, this range reduces radiation exposure to critical organs, leading to fewer side effects. These findings provide practical, evidence-based guidance for bladder filling protocols to improve patient outcomes. Patient summary: For patients receiving radiation therapy for cervical cancer, keeping the bladder moderately full (about 300-500 mL) during treatment may help protect the bladder and bowel from radiation damage. This simple measure was linked to fewer mild side effects, such as bladder irritation or diarrhea. Patients can discuss with their doctors how to maintain a comfortable bladder volume to potentially improve their quality of life during and after treatment.
