The use of the amplatz sheath in percutaneous nephrolithotomy: does amplatz sheath size matter?
Article in Current urology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
objectivesTo evaluate the effect of Amplatz sheath size used in percutaneous nephrolithotomy (PCNL) on postoperative outcome, bleeding, and renal impairment rates. MATERIALS AND
methodsOne-hundred and ten patients who underwent uneventful percutaneous nephrolithotomy between November 2011 and October 2012 were included in the study. The patients were divided into 5 groups based on Amplatz sheath size (22, 24, 26, 28 and 30 Fr). Groups were comppared in terms of pre- and post-operative mean hemoglobin, creatinine, nephrostomy time, nephrostomy tube diameter, operative time, and fluoroscope time.
resultsMean operative time, preoperative hemoglobin and creatinine values were similar in all groups. Postoperative mean hemoglobin level was significantly lower and postoperative mean creatinine level was significantly higher in patients who were treated with a larger Amplatz sheath when compared to a smaller size (p < 0.05). It was observed that nephrostomy time and nephrostomy tube size significantly increased as the Amplatz sheath size increased. Seven patients presented with postoperative infection (1, 2, 1, 0 and 3 patients in Group I, II, III, IV, and V respectively), 13 patients presented with bleeding requiring blood transfusion (2, 4, and 7 patients in Group III, IV, and V respectively), and residual stone was observed in 9 patients (5, 2, 0, 1, and 1 patients in Group I, II, III, IV, and V respectively).
conclusionAlthough the use of a larger Amplatz sheath for larger stones seems to be suitable, this is not the case for smaller stones. For smaller stones, a smaller Amplatz sheath size would be useful to decrease the bleeding and renal impairment rates.
