    Abstract A 53-year-old man with a history of surgery for renal cancer was referred to our hospital due to massive hemoptysis. Contrast-enhanced CT revealed a well-enhanced pulmonary nodule suggestive of a tumor (diameter of 16 mm), which was considered a causal lesion. Bronchial artery embolization was successfully performed and subsequently hemoptysis disappeared. However, hemoptysis recurred 6 months later, and the tumor was surgically resected. Pathological examination revealed the resected tumor was a lung metastasis of renal cell carcinoma, which directly invaded into pulmonary bronchus. Hemoptysis secondary to lung metastasis of renal cell carcinoma has rarely been reported in the literature.

    Abstract Uro-lymphatic fistulas are rare, and involve communication between the renal collecting system and the lymphatic system. The disorder is usually caused by the obstruction of lymphatic vessels due to several diseases, leading to chyluria. Here, we report the case of a patient with a uro-lymphatic fistula, considered to be associated with urolithiasis.

    Abstract A 60-year-old woman taking anti-platelet drugs was referred to the hospital for the treatment of advanced renal cell carcinoma. CT revealed that the tumor had a diameter of 5 cm and hyper-vascularity. Percutaneous CT-guided cryoablation (CA) was indicated. Since preprocedural arterial embolization failed to provide sufficient embolic effects, sunitinib maleate was administered. It provided good tumor devascularization and volume reduction, which corresponded to downstage. Therefore, the administration contributed to successfully performing subsequent percutaneous CT-guided CA with no serious hemorrhagic complications. Sunitinib maleate may be an alternative to conventional treatments before CA for renal cell carcinoma.

    Abstract Objectives: To investigate whether the number and size of endometrial-leiomyoma fistulas (ELFs) change following uterine artery embolization (UAE) for leiomyoma and the correlation between ELFs and vaginal discharge (VD).
    Materials & methods: This study was a retrospective analysis of 100 patients who underwent UAE at a single institution between May 2016 and March 2021. They all underwent MRI at baseline, 4 months, and 1 year after UAE. The number and size of the ELFs were compared with the MRI images each time. The ELF tumor characteristics and the correlation between the ELFs and VD were assessed. Additional gynecologic interventions due to VD associated with ELFs were evaluated.
    Results: No ELF was observed at baseline. Ten ELFs were noted in nine patients at 4 months, and 35 ELFs were noted in 32 patients 1 year after UAE. The ELFs significantly increased over time (p = 0.004, baseline vs. 4 months; p < 0.001, 4 months vs. 1 year). The ELF size did not significantly change over time (p = 0.941). The tumors developing ELFs after UAE were mainly located at the submucosal or intramural area contacting the endometrium at baseline, with a mean size of 7.1 (2.6) cm. Nineteen patients (19%) had VD 1 year after UAE. There was no significant correlation between VD and the number of ELFs (p = 0.80). No patients underwent additional gynecologic interventions due to VD associated with ELFs.
    Conclusion: ELFs increased in number and did not disappear over time after UAE in most tumors.
    Clinical relevance statement: Despite the MR imaging findings, within the limited data of this study, ELFs were not seemingly associated with clinical symptoms, including VD.
    Key points: • Endometrial-leiomyoma fistula (ELF) is a complication of uterine artery embolization (UAE). • ELFs increased in number over time after UAE and did not disappear in most tumors. • Most tumors developing ELFs after UAE were located near/contacted the endometrium and were larger.

    Abstract Uro-lymphatic fistulas are rare, and involve communication between the renal collecting system and the lymphatic system. The disorder is usually caused by the obstruction of lymphatic vessels due to several diseases, leading to chyluria.
