Representing 0.43% of all urinary bladder neoplasms, leiomyomas are rare mesenchymal tumours with a benign pathophysiology. There have only been approximately 250 cases published on this subject, necessitating further inquiry into this disease and effective management protocols. Treatment options may include a broad spectrum of surgical interventions, from minimally invasive resection to radical cystectomy, depending on the location, size and symptoms associated with the tumour. To date, few cases of leiomyoma have resulted in recurrence after removal, and zero have reported malignant transformation. Described here in detail is a woman in her early 40s who presented with a history of chronic pelvic pain and irregular vaginal bleeding. The urology team completed further evaluation after imaging discovered a concerning bladder lesion. Eventually, she underwent transurethral resection, with the subsequent pathology revealing a rare diagnosis of leiomyoma in the urinary bladder.
平滑肌瘤占所有膀胱肿瘤的 0.43%，是一种罕见的良性间叶组织肿瘤。目前仅有大约 250 例相关病例发表，因此需要进一步研究这种疾病并制定有效的管理方案。治疗选择可能包括广泛的手术干预，从微创切除到根治性膀胱切除术，具体取决于肿瘤的位置、大小和相关症状。迄今为止，少数平滑肌瘤切除后复发，且无一例报告发生恶性转化。这里详细描述了一位 40 多岁的女性，她因慢性盆腔疼痛和不规则阴道出血就诊。泌尿科团队在影像学检查发现膀胱有可疑病变后进行了进一步评估。最终，她接受了经尿道切除术，随后的病理检查显示罕见的膀胱平滑肌瘤诊断。
