Percutaneous nephroscopy combined with ultrasound-guided negative-pressure suction for the treatment of perinephric abscess: a case series.
Article in BMC urology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundDrainage is indicated in many patients with a perinephric abscess (PA). Surgical drainage is associated with trauma and slow recovery, while percutaneous drainage can be ineffective in some patients. We report on 11 patients with PA treated by percutaneous nephroscopy combined with ultrasound-guided negative-pressure suction under local anesthesia.
methodsThis case series included 11 PA patients operated on from January 2013 to June 2020. All patients received percutaneous nephroscopy combined with ultrasound-guided negative-pressure suction. Data, including operation time, volume of intraoperative blood loss, volume of intraoperative pus suction, time of postoperative drainage tube indwelling, time to restore normal body temperature, length of postoperative hospital stay, and intraoperative and postoperative complications, were collected.
resultsThe age of the patients was 59 (53-69) years. Eight, six, two, and two patients had hypertension, type 2 diabetes, rheumatoid arthritis, and renal calculi, respectively. The operations were successful forall11 patients. Eight, two, and one patients required one, two, and three channels, respectively, to clear their abscess. The average operation time was 44 (30-65) min, and intraoperative blood loss was 16 (10-20) ml. The volume of intraoperative pus suction was 280 (200-400) ml, time of postoperative drainage tube indwelling was 8.2 (6-12) days, and time to restoring normal body temperature was 0.8 (0.5-2) days. The average postoperative hospital stay was 9.8 (7-14) days. No severe intraoperative or postoperative complications occurred. The postoperative follow-up time was typically 4.8 (3-8) months, and there were no recurrences.
conclusionPercutaneous nephroscopy combined with ultrasound-guided negative-pressure suction might be a feasible method for treating PA.
