Clinical characteristics of patients with ureteral endometriosis and severe renal impairment identified by diuretic renal dynamic imaging.

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
Purpose: This study aimed to summarize the clinical characteristics, surgical management, and follow-up outcomes of patients with severe renal impairment caused by ureteral endometriosis. Methods: We conducted a retrospective analysis of the clinical data of 15 patients with severe renal impairment caused by ureteral endometriosis treated at the First Hospital of Peking University between January 2000 and January 2022. Results: Among the 15 patients, 3 (20.0%) were asymptomatic, whereas 12 (80.0%) reported endometriosis-related pain and/or urinary symptoms. Seven patients (46.7%) reported lumbar discomfort. All patients underwent preoperative diuretic renography, which showed an affected-kidney glomerular filtration rate (GFR) of <15 mL/min in all cases. Despite severe impairment of the affected kidney, only one patient had elevated serum creatinine levels, suggesting that serum creatinine may fail to detect severe unilateral renal impairment when contralateral renal function is preserved. Eight patients (53.3%) underwent ipsilateral nephrectomy, four (26.7%) underwent ureteroneocystostomy, and three (20.0%) underwent ureterolysis. During a median follow-up of 61 months, the majority of patients' symptoms improved. Among the seven patients who underwent kidney function-preserving procedures, hydronephrosis disappeared in six patients and significantly improved in one patient on postoperative ultrasonography. No reoperation for recurrent ureteral obstruction was documented during follow-up. Conclusion: Delayed diagnosis of ureteral endometriosis may lead to severe unilateral renal impairment and even the need for nephrectomy. Normal serum creatinine levels do not exclude severe dysfunction of the affected kidney. Early urinary tract imaging, split renal function assessment, individualized surgery, and long-term follow-up are essential for renal preservation.
