Prevalence of Urinary Tract Injuries in Patients With Rectal Cancer Undergoing Low Anterior Resection Versus Abdominal Abdominoperineal Resection at a Tertiary Care Center in Latin America.

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
introductionUrinary tract injuries are uncommon complications in rectal cancer. However, there are no epidemiological data documenting their frequency in the patient population treated at the colorectal tumor service of the Oncology Hospital at CMN Siglo XIX.
objectiveThe objective of this study is to compare and report the prevalence of urinary tract injuries in patients with rectal cancer undergoing low anterior resection (LAR) or abdominoperineal resection (APR) at a high-specialty center in Latin America. MATERIALS AND
methodsAn observational, retrospective, and cross-sectional study was conducted between 2017 and 2018. Patients with histopathologically confirmed diagnoses were included, and clinical and surgical variables were recorded, including the presence of a urinary tract injury. Statistical tests for normality, bivariate analysis, and likelihood ratios were applied, considering p < 0.05 as significant.
resultsEight cases of urinary tract injuries were identified, corresponding to a prevalence of 5.2 percent, which is higher than that reported in international literature. No injury was recorded in 94.8 percent of cases.
conclusionThese findings suggest the need to improve intraoperative monitoring and prevention in such procedures. One of the ideal methods for ureteral identification that has recently gained popularity is indocyanine green, which is used to highlight ureteral anatomy and can serve as an alternative to methylene blue. The main advantage of this method is its accessibility, as it can be applied intraoperatively without significantly prolonging surgical time.
