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
purposeThis prospective single center study evaluated the feasibility, perioperative outcomes, and surgeon experience of a novel digital disposable semirigid nephroscope (Redpine
methodsBetween March 2024 and March 2025, 328 patients underwent SM-PCNL using the digital disposable nephroscope across institutions. Inclusion criteria encompassed all consenting patients with renal stones managed via prone/supine SM-PCNL (14-22 Fr suction sheath). The digital disposable scope served initially as a cystoscope to place the guidewire and later used for nephroscopy. Data collected included patient/stone characteristics, operative details (lithotripsy time, access technique), complications (Clavien-Dindo), surgeon satisfaction (5-point Likert scale), and stone-free rate (SFR). SFR was assessed via low-dose CT at 30 days (Grade A: no fragments; Grade B: ≤4 mm fragment).
resultsMedian stone diameter was 1.7 cm (IQR 1.3-2.3). Median lithotripsy and total operative times were 8 min (IQR 5-16) and 22 min (IQR 20-35), respectively. Intraoperative SFR was 96%. Surgeons reported excellent instrument satisfaction (median Likert score 1/5) for vision, ease of use, and manoeuvrability within the pelvicalyceal system. Complications were rare: major (Clavien ≥ 3) occurred in 0.9% (n = 3, including colonic injury, pleural injury, sepsis. One case developed lower pole arteriorvenous fistula, managed by arterial angioembolization. At 30 days, SFR was 100%: Grade A (no fragments) in 47.9% (n = 157) and Grade B (≤ 4 mm fragment) in 52.1% (n = 171). Reintervention (ESWL) was needed in 1.2% (n = 4) within 3 months. Scope tip damage occurred in 0.6% (n = 2).
conclusionThe digital disposable nephroscope demonstrated excellent feasibility and safety in SM-PCNL, facilitating efficient stone clearance time (median 22 min), high SFR, minimal complications, and superior surgeon ergonomics. Its dual cystoscope-nephroscope functionality and plug-and-play design offer significant versatility, supporting its role in advancing minimally invasive PCNL.
