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
introductionIn adult patients, most ureteropelvic junction obstruction (UPJO) occurs secondarily. Concurrent UPJO with nephrolithiasis is not rare and simultaneous treatment by performing laparoscopic pyeloplasty and endoscopic stone removal has been suggested. In the case of atypical anatomy or previously failed pyeloplasty, a laparoscopic ureterocalicostomy is preferred. This study presents a case where a severe UPJO coexistence with renal stone was treated with laparoscopic ureterocalicostomy and direct lithotripsy using ShockPulse lithotripter through the laparoscopic port. PRESENTATION OF CASE: A 24-year-old male with a history of bilateral open pyelolithotomy came with left flank pain. Further examination revealed a left UPJO and multiple nephrolithiasis. During laparoscopic pyeloplasty, significant adhesion and fibrosis were encountered around the ureteropelvic junction, rendered it challenging to perform pyeloplasty. Consequently, left ureterocalicostomy and direct lithotripsy using ShockPulse lithotripter through the laparoscopic working port were performed. After 3 months, the double-J stent was removed with no complication. DISCUSSION: The typical minimal invasive options for stone removal for UPJO with large or multiple nephrolithiasis are through percutaneous nephrolithotripsy (PCNL) or direct stone removal during laparoscopy. However, by using the ShockPulse lithotripter, large or multiple calculi can be easily fragmented and siphoned through the laparoscopic port. This technique might help to shorten the operative time and reduce the risk of migrating stone to the abdominal cavity after opening the inferior calyx.
conclusionSimultaneous lithotripsy using ShockPulse lithotripter during laparoscopic ureterocalicostomy is a safe and feasible option in treating complex UPJO concurrent with renal stone.
