The role of triple double-J stents in managing uretero-ileal anastomotic strictures following urinary diversion.
Observational study in World journal of urology, 2026. 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
purposeTo evaluate the efficacy and safety of triple double-J (DJ) stents in treating uretero-ileal anastomotic strictures (UIAS) following urinary diversion procedures (ileal conduit and ileal orthotopic neobladders). PATIENTS AND
methodsA prospective analysis and follow-up observation were conducted on patients who underwent triple-stent placement for UIAS after urinary diversion at our center between August 2022 and January 2024. During follow-up, surgical success rates, renal function parameters, and complication incidence were evaluated. Surgical success was defined as either ureteral stents remaining in situ with unobstructed urinary drainage or, in cases where there was unplanned stent replacement or removal, the sustained maintenance of stable renal function parameters without subsequent deterioration.
resultsDuring the 2-year follow-up period, patients underwent regular triple-stent replacement at our hospital every 6 months. The overall success rate of triple-stent reached 83.3% among 29 patients (36 cases). At the 2-year follow-up, there was a statistically significant decrease in hydronephrosis volume (59.0 ± 55.8 vs. 30.2 ± 17.0 cm³, p = 0.008), blood creatinine level (124.7 ± 38.3 vs. 109.6 ± 22.3 µmol/L, p < 0.001), and urea nitrogen level (7.4 ± 2.6 vs.6.6 ± 1.8 mmol/L, p < 0.001). Glomerular filtration rate remained stable (54.1 ± 22.0 vs. 53.3 ± 20.6 mL/min/1.73 m², p = 0.067). Surgical complications during follow-up included pain (5.6%), hematuria (2.8%), urinary tract infection (11.1%), and lower urinary tract symptoms (13.9%).
conclusionsOur center innovatively proposed the triple-stent for treating UIAS in patients after urinary diversion. Two-year follow-up data demonstrate that, for patients unsuitable for surgical reconstruction or with limited financial resources, regular triple-stent placement and replacement is feasible, showing good long-term patency rates and a low incidence of adverse events.
