Robot-assisted laparoscopic management of primary urethra clear cell adenocarcinoma in females: a case report and literature review.
Article in Frontiers in surgery, 2026. 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
Background: Primary clear cell carcinoma of the urethra (CCAU) in women is extremely rare. There are only limited reported cases in the literature, with no standardized treatment protocol presently available. This article aims to explore the clinical characteristics, diagnostic difficulties, treatment strategies, and prognosis of female primary clear cell adenocarcinoma of the urethra, and supplement it with relevant literature analysis to improve the understanding of this rare disease. Methods: A 57-year-old female patient presented with progressive dysuria for half a year and recurrent urinary retention for 2 months. After evaluation by imaging, endoscopic, and pathological examinations, the patient underwent robot-assisted laparoscopic radical resection of urethral cancer, with the postoperative pathology finally diagnosed as CCAU. Innovative surgical positioning and auxiliary methods were employed during the operation to effectively optimize the treatment and promote the smooth progress of the operation. Results: Postoperative pathology revealed urethral clear cell adenocarcinoma with sarcomatoid differentiation in some areas. The patient underwent a successful surgical procedure with an uneventful postoperative recovery. Follow-up imaging showed no signs of tumor recurrence. The patient experienced a postoperative complication of urinary incontinence. Conclusion: CCAU is a rare and highly malignant tumor with poor prognosis. The diagnosis of this disease primarily relies on pathological immunohistochemistry and differential exclusion of metastatic tumors. Multidisciplinary collaboration and radical surgery are key to successful treatment, with consideration given to adjuvant therapy and close postoperative follow-up. At present, no standard surgical regimen exists, and the efficacy of postoperative adjuvant therapy remains unclear.
