  • 文章类型: Case Reports
    输尿管血肿是在抗凝治疗期间发生的罕见并发症,文献中报道的病例少于10例。出血并发症被低估了。它们影响约10%的长期抗维生素K(AVK)治疗的患者。肉眼血尿的出现可能表明存在潜在的有机损伤。临床上,输尿管血肿表现为腰椎或腹痛,常伴有肉眼血尿。影像学在其诊断中起主要作用。在纠正凝血障碍和立即停止抗凝治疗之后,临床和放射学演变总是迅速有利的。我们在这项工作中报告了一名50多岁的患者在抗凝治疗期间出现输尿管血肿的情况。
    Ureteral hematoma is a rare complication occurring during anticoagulant therapy, with fewer than 10 cases reported in the literature. Bleeding complications are underestimated. They affect about 10% of patients treated with long-term anti-vitamin K (AVK). The appearance of macroscopic hematuria may indicate the presence of underlying organic damage. Clinically, ureteral hematoma is manifested by lumbar or abdominal pain often associated with macroscopic hematuria. Imaging plays a major role in its diagnosis. Clinical and radiological evolution is always rapidly favorable after the correction of coagulation disorders and the immediate discontinuation of anticoagulant treatment. We report in this work the case of a patient in her 50s who presented a ureteral hematoma during her anticoagulant treatment.

    报告在狗的单侧隐睾手术中成功处理了输尿管结扎后的双侧输尿管梗阻,并利用了双侧输尿管支架置入和新输尿管膀胱造口术。
    一位体重30公斤的7个月大的男性阉割威马纳尔被送到一所大学教学医院,以评估4天的嗜睡史,呕吐,剖腹探查左侧单侧隐睾去势手术后的神经束。基于同时存在严重氮质血症和双侧肾积水和输尿管的超声检查结果,这只狗被诊断为疑似双侧输尿管梗阻。这只狗进行了剖腹手术,发现双侧输尿管结扎,并通过左侧新子宫膀胱造口术和右侧逆行输尿管支架置入术进行了纠正。由于新子宫膀胱造口术部位的并发症,随后进行了左侧输尿管支架的放置。最终,两个输尿管支架在几个月后均能被移除.在初始双侧输尿管结扎后532天,该狗在临床上表现良好,基线肌酐为1.5mg/dl(132.6μmol/L)。
    本病例报告描述了使用双侧输尿管支架和新输尿管造口术的方法对雄性犬的医源性双侧输尿管阻塞的成功长期治疗。
    UNASSIGNED: To report the successful management of the bilateral ureteral obstruction secondary to ureteral ligation during unilateral cryptorchid surgery in a dog with the utilization of bilateral ureteral stent placement and a neoureterocystostomy procedure.
    UNASSIGNED: A 7-month-old male-castrated Weimaraner weighing 30 kg was presented to a university teaching hospital for evaluation of a 4-day history of lethargy, vomiting, and stranguria following exploratory laparotomy for a left-sided unilateral cryptorchid castration. Based on the concurrent presence of severe azotemia and ultrasonographic findings of bilateral hydronephrosis and hydroureter, the dog was diagnosed with the suspected bilateral ureteral obstruction. The dog underwent a laparotomy which revealed bilateral ureteral ligation which was corrected with a left-sided neoureterocystostomy and right-sided retrograde ureteral stent placement. Subsequent placement of a left-sided ureteral stent due to complications with the neoureterocystostomy site was performed later. Ultimately, both ureteral stents were able to be removed a few months later. The dog was clinically doing well with a baseline creatinine of 1.5 mg/dl (132.6 μmol/L) 532 days following initial bilateral ureteral ligation.
    UNASSIGNED: This case report describes the successful long-term management of iatrogenic bilateral ureteral obstructions in a male dog using a combination of bilateral ureteral stents and neoureterocystostomy.

    输尿管小细胞神经内分泌癌(SCNEC)是一种罕见的肿瘤,占所有输尿管肿瘤的不到0.5%。SCNEC肿瘤具有高度侵袭性,患者预后不良。输尿管SCNEC与其他病理类型的肿瘤碰撞极为罕见。在本文中,我们介绍了一例输尿管小细胞癌与鳞状细胞癌碰撞的病例,并回顾了有关临床病理特征的文献。因此肿瘤的治疗和预后。据我们所知,这是第2例输尿管SCNEC与SCC碰撞的病例.
    一名64岁男性患者,有1个月的肉眼血尿和3个月的左侧腹疼痛病史。CT尿路造影显示输尿管上段有软组织肿块,在对比增强CT上略有增强。在患者被诊断出患有左输尿管肿瘤后,进行了肾输尿管切除术。显微镜和免疫组织化学检查证实肿块是SCNEC与SCC碰撞。手术后两个月,患者接受辅助化疗(顺铂/依托泊苷).经过14个月的随访,未发现局部复发或远处转移。
    伴有SCNEC的输尿管碰撞癌主要发生在亚洲个体,术前难以诊断,并且具有很强的侵入性。目前输尿管碰撞癌的治疗是以手术为主的综合治疗。
    UNASSIGNED: Small cell neuroendocrine carcinoma (SCNEC) of the ureter is a rare tumour, accounting for less than 0.5% of all ureteral tumours. SCNEC tumours are highly aggressive and patients have a poor prognosis. Ureteral SCNEC colliding with other pathological types of tumours is extremely rare. In this paper, we present the case of a patient with ureteral small cell carcinoma colliding with squamous cell carcinoma and review the literature regarding the clinicopathological features, treatment and prognosis of thus tumour. To the best of our knowledge, this is the second identified case of ureteral SCNEC colliding with SCC.
    UNASSIGNED: A 64-year-old male patient presented with a history of 1 month of gross haematuria and 3 months of left flank pain. CT urography revealed a soft tissue mass in the upper ureter, which was slightly enhanced on contrast-enhanced CT. Nephroureterectomy was performed after the patient was diagnosed with a tumour in the left ureter. Microscopy and immunohistochemical examination confirmed the mass to be a SCNEC collision with SCC. Two months after the surgery, the patient received adjuvant chemotherapy (cisplatin/etoposide). After 14 months of follow-up, no local recurrence or distant metastasis was found.
    UNASSIGNED: Ureteral collision carcinoma with SCNEC predominantly occurs in Asian individuals, is difficult to diagnose preoperatively and is highly invasive. The current management of ureteral collision carcinoma is a comprehensive treatment based on surgery.

    Upper urinary tract neoplasms comprise only 5% of urinary malignancies overall, the overwhelming majority showing an urothelial histology. Nonurothelial lesions represent 1.9% of upper tract neoplasms, and small cell carcinomas (SmCCs) only account for a minute fraction of them, with few cases reported in the literature to date. In the genitourinary tract, these lesions are most frequently found in the urinary bladder, where they tend to show a mixed histology with a characteristic small cell neuroendocrine component that is positive for chromogranin A, synaptophysin, and CD56 immunostains. Urinary SmCCs are almost invariably aggressive, with a propensity to infiltrate surrounding tissues and vascular structures. Unfortunately, clinical stage at presentation is often advanced, with early dissemination to lymph nodes or distant organs in a significant proportion of patients. For the most part, prognosis is dismal and can be predicted by the pathologic stage at diagnosis. Recently, new chemotherapeutic regimens have shown some potential benefit for the treatment of urinary SmCC, albeit not achieving curative results. Here we present the case of a 71-year-old male patient with a history of treated bladder urothelial carcinoma that presented with subacute flank pain and was diagnosed with a primary pure SmCC of the ureter. Besides the usual neuroendocrine immunomarkers, this tumor showed intense positivity for TTF-1 (thyroid transcription factor-1), a phenomenon that has been described for extrapulmonary SmCC of other locations.

    The presence of a ureter within an inguinal hernia is an extremely rare entity, usually discovered incidentally during herniorrhaphy and may pose a surgical risk. Early preoperative diagnosis is crucial to guide proper surgical approach and to preserve renal function.
