Craniocaudal bull's eye technique for superior calyceal access during percutaneous nephrolithotomy: Determination of angle, efficacy, and outcomes.

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
Introduction: The classical lateromedial "bull's eye" technique for fluoroscopy-guided access for percutaneous nephrolithotomy (PCNL) may be inappropriate for a superior calyx puncture since its infundibulum has a craniocaudal (CC) orientation. We evaluated a modified bull's eye technique in a CC orientation (craniocaudal bull's eye [CCBE]) for superior calyceal access during PCNL. Methods: In an Institutional Review Board-approved, two-phase study, we evaluated the ideal angle for CC puncture in 24 patients who underwent CT scans for unrelated indications. Subsequently, patients planned for superior pole access PCNL were prospectively enrolled for the study. The maximum CC angle allowing puncture below the 11 Results: CT scans of 24 patients were reviewed, and the ideal angle for CC rotation for the left and right kidney was 68.6° ± 4.5° and 68.1° ± 7.3°, respectively. All these would have resulted in access above the 10 Conclusions: Superior calyceal access can be achieved using a 15° CCBE technique. This is safe and successful in most patients with a single attempt and short fluoroscopy time.
