Complications of Encrusted Stents in Recurrent Nephrolithiasis: A Case Report.
Article in Cureus, 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
Chronic kidney disease (CKD) and recurrent nephrolithiasis can lead to significant renal impairment due to obstruction, infections, and direct damage from stones. Timely intervention is crucial to prevent further deterioration, especially in patients with poorly controlled diabetes and encrusted stents. We present a 56-year-old male with poorly controlled type 2 diabetes and stage 3 CKD. He had recurrent nephrolithiasis and initially underwent ureteral stenting, followed by a second stent placement due to pyelonephritis and significant encrustation. Imaging revealed a large bilateral calculous mass. The patient initially underwent nephrolithotomy with spectrophotometric analysis of the stones and had a favorable postoperative outcome. This case highlights the impact of untreated stents and recurrent stones in CKD patients. Encrusted stents can cause hydronephrosis, secondary obstruction, and increased renal pressure, contributing to renal function decline. Surgical intervention, including nephrolithotomy and ureterolithotomy, can improve renal function and prevent further complications. Spectrophotometric analysis of the stones revealed struvite and uric acid stones, both linked to infections and metabolic factors. Early stone removal and management of encrusted stents are essential in CKD patients with recurrent nephrolithiasis. A multidisciplinary approach is necessary to optimize treatment and prevent further renal deterioration. Regular follow-up is critical to avoid irreversible renal damage.
