Fluoroscopy-guided trans-urethral exchange of double-J ureteral stents.
Article in BMC 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
backgroundFor patients with malignant ureteral obstruction or stricture who require long-term internal drainage, plastic double-J stents (DJ stents) represent the mainstay of therapeutic strategies. DJ stents should be replaced at least once every 6 months to avoid infection or obstruction. Although DJ stents are generally replaced under cystoscopy, successful fluoroscopy-guided retrograde replacement of DJ stents in the interventional suite has been described in the literature.
methodsBetween April 2004 and May 2020, we exchanged 143 DJ stents in 19 male and 22 female patients under fluoroscopic guidance using Nelaton catheters, snare catheters, and 8F DJ stents. All procedures were performed with patients under sedation and local anesthesia. There were 39 patients with malignant ureteral obstruction and two patients with benign ureteral strictures. This study was approved by the Institutional Review Board. Technical success, clinical success, complications, procedure time, and mean interval between two procedures were retrospectively reviewed, and the factors affecting the success rate of the procedure were analyzed.
resultsObstruction was detected at the abdominal ureter in 4 patients, pelvic ureter in 29 patients, and intravesical ureter in 8 patients. Twenty-six patients underwent two or more sessions of the procedures, whereas 15 patients underwent single-session procedures. Total 34 outpatient-based procedures and 109 inpatient-based procedures were performed. Technical success and clinical success were achieved in 94.4% (135/143) and 93.3% (126/135) procedures, respectively. Mean procedure time was 21.5 min (range 9-192 min). Mean procedure interval was 101.8 days (range 5-306 days). Technical success was negatively affected by male sex and obstruction at the pelvic ureter and was positively affected by previous successful exchange. Left-sided ureteral stent placement and old age negatively influenced clinical success. Septic shock occurred in one patient and was treated with antibiotics.
conclusionFluoroscopy-guided trans-urethral exchange of DJ stents is an effective and less painful procedure.
