A Rare Case of Bladder Neck Obstruction Caused by Extrusion of Necrotic Tissue Following Transurethral Water Vapor Energy Therapy for Benign Prostatic Hyperplasia.

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
Transurethral water vapor energy (WAVE) therapy is a minimally invasive treatment for benign prostatic hyperplasia (BPH) that typically results in coagulative necrosis without significant clinical sequelae. However, rare complications such as urinary tract obstruction due to sloughed necrotic tissue have been reported. We report the case of a 67-year-old man with BPH who developed acute urinary retention and underwent WAVE. Although his initial postoperative course was favorable, he subsequently presented with worsening voiding dysfunction. Imaging revealed a soft tissue mass with surface calcification obstructing the bladder neck. Cystoscopy identified a calcified mass adherent to the bladder neck, and endoscopic removal of the underlying necrotic tissue resulted in rapid improvement of urinary symptoms. This case highlights a rare but significant complication of WAVE. Clinicians should consider the possibility of bladder outlet obstruction due to necrotic tissue extrusion in patients with delayed postoperative urinary symptoms.
