Percutaneous nephroscopy combined with flexible ureteroscopy for treating calyceal outlet occlusion after partial nephrectomy: a case report.
Article in BMC urology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Tumors located near the renal collecting system often led to collecting system injuries during partial nephrectomy, with urinary leakage caused by collecting system rupture being a common complication. We report a rare case of another type of collecting system injury: intraoperative suturing caused occlusion of the upper calyceal outlet of the right kidney, resulting in hydronephrosis of the upper calyx and persistent urinary leakage postoperatively. Using a combination of percutaneous nephroscopic and ureteroscopic approaches, we located the occluded calyceal outlet and successfully restored urine drainage from the obstructed calyx by performing laser incision and balloon dilation to open and enlarge the calyceal outlet. Our case demonstrates that for iatrogenic occlusion of renal calyceal outlets caused by partial nephrectomy, combining percutaneous nephroscopic and ureteroscopic endoscopic surgery can effectively resolve calyceal obstruction.
