■成人膀胱中很少发现异位组织。目前,有报道称膀胱异位前列腺和结肠组织。这些异位组织表现为膀胱肿块并引起下尿路症状。然而,膀胱中的异位海绵体从未被报道过,其临床特点和治疗方法尚未探讨。
■一名3岁男孩因尿频1个月入院。体检并不显著。其他医院的尿液分析显示尿液白细胞计数升高,为17.9/ul。此外,超声显示可能有膀胱肿块.CT和MRI显示膀胱三角区边缘病变(1.9×1.9cm)。通过术前成像,我们诊断为膀胱肿瘤(倾向于良性)。经尿道膀胱肿瘤切除术。不幸的是,由于难以通过尿道切除切除的组织,手术未能成功.随后,行膀胱切开和肿瘤切除术。肿瘤被成功切除。令人惊讶的是,术后病理显示肿瘤组织为海绵体。病理诊断为膀胱海绵体异位。术后未发现并发症,随访期间未见复发。
■膀胱中的海绵体异位从来没有报道过儿童,这是一种良性肿瘤,具有快速增殖和大尺寸。建议手术。然而,由于尿道狭窄和手术器械有限,膀胱肿瘤的经尿道切除术很难进行。膀胱切口和肿瘤切除术可能是首选。
UNASSIGNED: Ectopic tissue is rarely found in the bladder for adults. Currently, there have been
reports of ectopic prostate and colon tissue in the bladder. These ectopic tissues are manifested as a bladder mass and cause lower urinary tract symptoms. However, the ectopic corpus cavernosum in the bladder has never been reported, and its clinical characteristics and treatment have not been explored yet.
UNASSIGNED: A 3-year-old boy was admitted to the hospital due to 1 month of urinary frequency. The physical examination was unremarkable. Urine analysis from other hospitals showed an elevated urine white blood cell count of 17.9/ul. In addition, ultrasound indicated a possible bladder mass. CT and MRI showed a well-margined lesion (1.9×1.9 cm) in the bladder trigone. Through preoperative imaging, we diagnosed a bladder tumor (inclined towards benign). The transurethral resection of the bladder tumor was performed. Unfortunately, the surgery was unsuccessful due to the difficulty in removing the excised tissue through the urethra. Subsequently, bladder incision and tumor resection were performed. The tumor was successfully removed. Surprisingly, the postoperative pathology showed that the tumor tissue was corpus cavernosum. The pathological diagnosis was ectopic corpus cavernosum in the bladder. No complications were found after the operation, and no recurrence was observed during follow-up.
UNASSIGNED: The ectopic corpus cavernosum in the bladder has never been reported for children, which is presented as a benign tumor with rapid proliferation and large size. Surgery is recommended. However, the transurethral resection of bladder tumors is difficult to perform due to narrow urethra and limited surgical instruments. Bladder incision and tumor resection may be preferred.
