Clinical study of the postural drainage lithotripsy system for the treatment of residual fragments after retrograde intrarenal surgery.
Trial report in World journal of urology, 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
purposeThe aim of this study was to compare the efficacy of two surgical modalities, Retrograde Intrarenal Ureteral Lithotripsy (RIRS) and PDLS + RIRS (Retrograde Intrarenal Ureteral Lithotripsy Combined with Posterior Drainage Lithotripsy System), in terms of stone removal, and to provide a basis for decision-making in clinical treatment.
methodsThis prospective study was carried out from 2022-02-16 to 2025-02-16 and included patients attending our hospital to collect clinical data, with surgery performed by the same attending surgeon. Patients with RFs determined by X-ray or CT 1-3 days after RIRS were selected and randomly divided into a treatment group (PDLS intervention) and a control group (conventional instruction). Patients in the treatment group were treated with preoperative water to hold urine and PDLS for 10 min, adverse effects and stone expulsion were recorded, and stone clearance status was determined by mean imaging follow-up for 20 days. The sample size was calculated using PASS 11 software, and 136 samples were identified for participation in the experiment, and the data were analysed using R 4.3.0 statistical analysis software.
resultsThere was no statistically significant difference between the two groups in terms of baseline characteristics such as Age, BMI, CT value, Gender, Hypertension, Diabetes, Respiratory disease, History of RIRS surgery, Haematuria, Back pain and Fever (P > 0.05). However, in terms of stone-free rate, the PDLS + RIRS group had a significantly higher stone-free rate (91.67%) than the RIRS group (75.00%), and the difference was statistically significant (χ²=6.94, P = 0.008).
conclusionStudies have shown that the PDLS + RIRS surgical approach has higher efficiency and advantages in stone removal, which can be used as a reference for clinical treatment. CLINICAL TRIAL REGISTRY NUMBER: ChiCTR2300071185; Registration date: 2023-05-06.
