POIROT trial: post-operative imaging after urethroplasty with peri-catheter retrograde urethrography or trial of voiding with voiding cysto-urethrography.
Trial report in World journal of urology, 2022. 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
purposeThis study directly compares peri-catheter retrograde urethrography (pcRUG) and voiding cysto-urethrography (VCUG) as early postoperative imaging after urethroplasty and aims to assess whether pcRUG is superior at avoiding catheter reinsertion.
methodsThis is a single-center, prospective, interventional study comparing pcRUG and VCUG after urethroplasty in a within-patient fashion. All participants were first evaluated with pcRUG and subsequently with VCUG, unless pcRUG revealed significant contrast extravasation warranting further catheter stay. The primary end-point was to assess whether pcRUG is superior at avoiding catheter reinsertion compared with VCUG. Secondary end-points included the amount of significant contrast extravasations missed on pcRUG and the differences in radiation exposure.
results80 patients were included in this study. Median (IQR) interval between surgery and first postoperative imaging was 16 (9-16) days. In 14/80 (18%) patients, the pcRUG showed significant contrast extravasation and catheter reinsertion was avoided, while this percentage is 0 by default for VCUG (p < 0.001). In the other 66/80 (82%) patients, a VCUG was performed and 1/66 (1.5%) of these was considered as significant contrast extravasation. Notably, 9/66 (14%) of these patients could not void during the investigation. Median (IQR) dose of radiation exposure during pcRUG and VCUG was, respectively, 120 (84-161) mGy/cm
conclusionsAfter urethroplasty, pcRUG is a valuable alternative for VCUG as early postoperative imaging. It has a comparable diagnostic yield, averts the risk of having to reinsert the catheter, avoids the problem of patients being unable to void during the examination and requires significantly less radiation.
