Tract dilation monitored by ultrasound in percutaneous nephrolithotomy: feasible and safe.

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 investigate the feasibility and safety of tract dilation monitored by ultrasound in percutaneous nephrolithotomy (PCNL) and identify suitable patients for this technique.
methodsPatients who underwent PCNL with only one access (24 Fr) using the balloon dilator or sequential dilators (Amplatz and telescopic metal dilators) from December 2014 to May 2018 in Beijing Tsinghua Changgung Hospital were retrospectively reviewed. Patients' demographic information, intra- and postoperative data were analyzed. Factors which would increase the success rate of ultrasound-guided balloon dilation were investigated by logistic regression analysis.
resultsThere were 986 PCNLs performed. 207 cases underwent balloon dilation, while 411 underwent sequential dilation. The two groups did not significantly differ in age, sex, BMI, stone diameter, access location, operation time, postoperative complication rate, and stone-free rate. The balloon dilation group comprised 207 patients (115 males, 92 females) with a mean age of 51 ± 10 years. Mean BMI was 25.2 ± 3.3 kg/m
conclusionsTract dilation using balloon catheter can be safely monitored by ultrasound, and is most suited to patients with a hydronephrotic target calyx.
