Sex-Specific Differences and Risk Factors for Postoperative Urinary Retention after Spine Surgery with TIVA.
Article in Journal of Korean Neurosurgical Society, 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
objectiveTo identify sex-specific risk factors for postoperative urinary retention (POUR) in patients undergoing spine surgery with total intravenous anesthesia (TIVA) and explore differences between male and female patients.
methodsA retrospective chart review was conducted on 446 adult patients (268 males, 178 females) who underwent spine surgery with TIVA from January 1, 2019 to December 31, 2023. Propensity score matching was applied to adjust for confounding variables, resulting in 328 matched patients (164 males and 164 females). Multivariable logistic regression analyses were performed to identify independent risk factors for POUR. Residual urine volume ≥300 mL was used to define POUR.
resultsMale patients had a higher incidence of POUR compared to female patients. Significant risk factors for POUR in males included myelopathy (adjusted odds ratio [aOR], 5.17; 95% confidence interval [CI], 1.11-24.15), benign prostatic hyperplasia (BPH) (aOR, 2.63; 95% CI, 1.02-6.78), and prolonged anesthesia time ≥240 minutes (aOR, 2.54; 95% CI, 1.13-5.72). No significant risk factors were found in female patients. Myelopathy and prolonged anesthesia were associated with an increased risk of POUR across the overall population.
conclusionMale sex, myelopathy, BPH, and prolonged anesthesia time are significant risk factors for POUR following spine surgery with TIVA. Given these findings, particular attention should be paid to myelopathy, a history of BPH, and anesthesia time in male patients.
