Radiation-Associated Aortocolonic Fistula in Urothelial Carcinoma: Multidisciplinary Management and Case Report.
Article in Clinical case reports, 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
Upper tract urothelial carcinoma (UTUC) is an uncommon and aggressive malignancy that often presents as an invasive disease. After receiving systemic therapy, stereotactic body radiation therapy (SBRT) offers a non-surgical option for consolidative local tumor control by delivering radiation doses in limited fractions. While SBRT is generally well tolerated in the treatment of UTUC, there is a small but serious risk of radiation-associated complications. We present a case of a 67-year-old male with metastatic UTUC of the renal pelvis treated with chemotherapy and immunotherapy. Due to persistent disease at the primary site, he underwent consolidative SBRT using a PULSAR (Personalized Ultra-fractionated Stereotactic Adaptive Radiotherapy) approach to his left kidney mass. Weeks later, he developed a renocolic fistula that was complicated by sepsis. Despite a diverting colostomy and antibiotics, he re-presented with hemorrhagic shock due to an aortocolonic fistula that required emergent endovascular aortic repair (EVAR). This case illustrates a rare but serious complication of consolidative SBRT in a patient with extensive retroperitoneal malignancy. Multidisciplinary planning and close surveillance are critical to ensuring the safe integration of SBRT in the management of metastatic UTUC.
