Exime prostatic stent in acute and chronic urinary retention.
Article in World journal of urology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeThe Exime prostatic stent, a silicone-based device designed for temporary urinary retention management, offers an alternative to indwelling urethral catheters (IUCs), allowing spontaneous voiding. This study aimed to compare the efficacy and safety of the Exime device with IUCs in patients with urinary retention due to benign prostatic obstruction (BPO).
methodsThis retrospective study included 43 patients from 2020 to 2024 with failed trial without catheter (TWOC) following acute urinary retention (AUR) secondary to BPO, prostate volume ≤ 120 mL, and intravesical prostatic protrusion < 5 mm. The stent was inserted under local anesthesia as an outpatient procedure. PRIMARY ENDPOINT: effectiveness in restoring urinary flow. Secondary endpoints: complications, patient preferences, and comparisons with IUCs.
resultsMedian patient age was 86 years (IQR 78-90); median prostate volume was 45 mL (IQR 40-61). The stent was successfully inserted in 42 patients (98%), with all achieving spontaneous voiding. Median post-void residual volume was 45 mL (IQR 38-73), and 70% retained the stent for ≥ 4 weeks. Complications included obstruction (14%), infection (9%), and migration (7%). Compared to IUCs, the Exime stent reduced symptomatic urinary tract infections (9% vs. 40%, p = 0.03), bladder spasms (16% vs. 84%, p < 0.001), and urinary leakage (0% vs. 30%, p < 0.001). Patients reported lower pain (VAS 2 vs. 8, p < 0.001) and higher satisfaction (VAS 8 vs. 1, p < 0.001).
conclusionThe Exime stent effectively managed urinary retention with fewer complications and higher patient satisfaction compared to IUCs.
