The multicentric potential of urothelial malignancy is well recognized, and the occurrence of urethral neoplasm after cystectomy is attributed to this characteristic of urothelial tumors. Eight instances of tumors in the glandular urethral remnant after subtotal urethrectomy illustrate the necessity of excising the fossa navicularis and urethral meatus when performing urethrectomy.
尿路上皮恶性肿瘤的多中心潜能已得到充分认识，膀胱切除术后尿道肿瘤的发生归因于尿路上皮肿瘤的这一特征。8例次全尿道切除术后腺性尿道残端肿瘤的病例说明了在进行尿道切除术时切除舟状窝和尿道口的必要性。
