Flexible ureteroscopy with ultrasound guidance for the treatment of parapelvic renal cysts: A complementary approach for locating the cystic wall.
Article in BMC urology, 2022. 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
backgroundFlexible ureteroscopic incision and drainage is a relatively new surgical method for treating parapelvic cysts. Considering that the intraoperative localization of the cyst may fail with a flexible ureteroscope, we use an innovative ultrasound-guided method to locate the cystic wall during flexible ureteroscopic surgery.
methodsWe retrospectively reviewed 17 consecutive cases of parapelvic renal cysts treated by ultrasound-guided flexible ureteroscopy between March 2017 and May 2020. The differences between the simple flexible ureteroscopic technique and ultrasound-guided flexible ureteroscopic technique were compared. The surgical procedures, postoperative complications, results and patient follow-ups were evaluated.
resultsThe cyst wall was seen clearly in 10 patients with ureteroscopic vision. Another 7 patients underwent ultrasound-guided flexible ureteroscopic surgery since it was difficult to identify the cyst wall. The mean operative time was 25.9 ± 8.7 min and 37.1 ± 10.1 min for the conventional and modified techniques, respectively (P = 0.004); the mean time to search for cysts was 17.6 ± 5.8 min and 26.5 ± 8.4 min, respectively (P = 0.002); and the mean incision time was 7.1 ± 4.9 min and 12.1 ± 5.6 min, respectively (P = 0.000). All of the patients were followed-up for 12 months, and no serious complications or recurrence were observed.
conclusionsWe demonstrated that it is feasible and safe to treat parapelvic renal cysts by ultrasound-guided flexible ureteroscopic incision and drainage. The small sample size and need for further studies were the limitations of our work.
