Predicting Initial Trial Without Catheter Failure After Prostate Deobstruction Surgery Using Preoperative Urodynamics.

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
purposeProstate deobstruction surgery is effective for relieving lower urinary tract symptoms in men with benign prostatic obstruction, yet some patients experience failure of the initial trial without catheter (TWOC) postoperatively and require recatheterization. This study aimed to identify clinical and urodynamic predictors of initial TWOC failure after prostate deobstruction surgery.
methodsA retrospective single-center study was conducted on 327 men who underwent prostate deobstruction surgery, including transurethral resection of the prostate, GreenLight laser photoselective vaporization, and holmium laser enucleation, at our institution from 2018 to 2024. Clinical characteristics, prostate volume, preoperative and postoperative uroflowmetry, and multichannel urodynamic parameters were evaluated. Initial TWOC failure was defined as recatheterization within 1 week of catheter removal. Logistic regression analysis was performed to identify predictive factors.
resultsAmong the 327 patients, 41 (12.5%) experienced initial TWOC failure. Uroflowmetry parameters improved significantly postoperatively. Multivariate analysis identified detrusor underactivity (DU) (odds ratio [OR], 2.773; P=0.012) and low bladder outlet obstruction (BOO) (OR, 2.881; P=0.041) as independent predictors. Patients with both risk factors exhibited a higher likelihood of initial TWOC failure (OR, 4.560; P=0.003), whereas those with high BOO and no DU showed lower risk (OR, 0.321; P=0.003). Notably, even among patients with high preoperative postvoid residual volume (PVR≥300 mL), those with high BOO and preserved detrusor contractility still demonstrated lower TWOC failure risk (OR, 0.154; P=0.018).
conclusionPreoperative multichannel urodynamics enhance initial TWOC risk stratification and support individualized postoperative catheter management. Patients with DU and low BOO may require prolonged catheterization. In contrast, early catheter removal appears feasible in patients with high BOO and preserved detrusor function, even when preoperative PVR is elevated.
