Duplication of the bladder with duplication of the posterior urethra is a relatively rare congenital malformation. Cases of sagittal septum duplication of the bladder with duplication of the posterior urethra have rarely been reported. Furthermore, the combination thereof with congenital megacolon is rare.
A 21-year-old male was admitted to our hospital because of frequent urination for two months. He presented to another hospital first with frequent urination and underwent computed tomography (CT) and testicular biopsy. Anti-inflammatory therapy was administered by the doctor to the patient. For further diagnosis and treatment, the patient went to the outpatient department in our hospital on June 6, 2022. After admission, the patient underwent ultrasound, CT, MRI, cystoscopy, and other related examinations and tests. The examination results suggested that the patient had duplication of the bladder with duplication of the posterior urethra. In addition, the patient's mother reported that he had suffered from long-term constipation with abdominal distension before the age of 5 years. At the time, he was admitted to the local hospital and was diagnosed with congenital megacolon based on the relevant examinations. After the patient was diagnosed with duplication of bladder and urethra, the doctor recommended surgical treatment to the patient. However, he considered that he only had frequent urination symptoms, and chose conservative treatment rather than to undergo surgical treatment. Thus, the doctor prescribed anti-inflammatory treatment. Four months later, the patient reported that frequent urination symptoms persisted, and was also considering fertility-related problems. The outpatient follow-up will be continued.
In this article, we summarize the imaging findings of duplication of the bladder with duplication of the posterior urethra and propose the advantages and disadvantages of each type of imaging examination. We also review the relevant literature on cases of bladders with duplication of the posterior urethra. The related differential diagnosis is summarized, and the significance of guiding clinical treatment and diagnosis is discussed.
膀胱重复合并后尿道重复是一种相对罕见的先天性畸形。膀胱矢状隔重复合并后尿道重复的病例很少有报道。此外，合并先天性巨结肠更为罕见。
一名 21 岁男性因尿频 2 个月入院。他最初因尿频就诊于另一家医院，接受了 CT 和睾丸活检。医生给予患者抗炎治疗。为了进一步诊断和治疗，患者于 2022 年 6 月 6 日到我院门诊就诊。入院后，患者进行了超声、CT、MRI、膀胱镜等相关检查和检验。检查结果提示患者患有膀胱重复合并后尿道重复。此外，患者的母亲报告称，他在 5 岁前长期便秘伴腹胀，当时他被送往当地医院，根据相关检查被诊断为先天性巨结肠。在患者被诊断为膀胱和尿道重复后，医生向患者推荐了手术治疗。然而，他认为自己只有尿频症状，选择了保守治疗而不是手术治疗。因此，医生开了抗炎治疗。4 个月后，患者报告尿频症状持续存在，也在考虑与生育有关的问题。将继续门诊随访。
本文总结了膀胱重复合并后尿道重复的影像学表现，并提出了各种影像学检查的优缺点。我们还回顾了膀胱后尿道重复的相关病例文献。总结了相关的鉴别诊断，并讨论了对指导临床治疗和诊断的意义。
