More than 90% of bladder cancer is composed of transitional cell carcinoma (TCC), being characterized by the development of multiple tumors in the entire urinary tract over time. When cystectomy is conducted, the urinary tract must be reconstructed by various procedures, which can include an orthotopic neobladder using the patient’s own intestine formed into a spherical shape anastomosed to the urethra. Using this procedure, patients can void urine from their own urethra even after cystectomy. The incidence of subsequent urethral cancer arising after cystectomy is known to be relatively high; however, if patients with a high risk of urethral recurrence are appropriately excluded, a neobladder can be safely provided for patients. Orthotopic neobladder use is reviewed from an oncological viewpoint and the patient’s quality of life after cystectomy for bladder cancer.

超过 90% 的膀胱癌由移行细胞癌 (TCC) 组成，其特点是随着时间的推移，整个泌尿道会出现多个肿瘤。进行膀胱切除术时，必须通过各种手术重建泌尿道，其中包括使用患者自己的肠道形成与尿道吻合的球形形状的原位新膀胱。通过这种手术，即使在膀胱切除术后，患者也可以从自己的尿道中排出尿液。众所周知，膀胱切除术后发生尿道癌的发病率相对较高；然而，如果适当排除尿道复发高风险的患者，则可以安全地为患者提供新膀胱。从肿瘤学角度和膀胱癌膀胱切除术后患者的生活质量来回顾原位新膀胱的使用。
