The influence of catheter type, the number of sutures and patients' age on percutaneous nephrostomy displacement.
Observational study in Radiology and oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPercutaneous nephrostomy displacement results in procedure failure, reducing quality of life in patients with hydronephrosis. Scarce data about factors influencing displacement led to evaluation of our data in order to give better insight into this topic. PATIENTS AND
methodsPatients admitted for percutaneous nephrostomy (PCN) exchange between March 3
resultsWe included 57 patients (35 males; mean age 71.4 years) in the study. Loop catheters with strings were implanted 58 times and without strings 17 times. Fixation was achieved by 55 single and by 20 double sutures. 17 PCN (22.7%) were displaced in designated period. The mean time from PCN implantation to exchange was 4.16 months. Neither catheter type, number of sutures or patients' age significantly influenced PCN displacement (chi-square 0.57, 0.34 and 0.61, respectively).
conclusionsNo significant difference in PCN displacement between two types of catheters and the number of fixing sutures was detected. Elderly patients had similar rates of PCN displacements as younger ones. The most important causes of PCN displacement remained probably patients' activity and a care for PCN during months after the implantation. Proper patients' education and care of the PCN are possibly the keys for long-term success.
