A Case of Urethral Carcinoma in Situ Resected by Urethrectomy of Anterior Urethra

A 62-year-old man had been treated for urethral stricture developed after his right kidney was harvested for donation to his sister 34 years ago. Transurethral biopsy was performed because of positive urinary cytology and squamous cell carcinoma was detected from the site of urethral stricture. The patient with the desire to preserve the penis was referred to our department. Magneticresonanc e imaging showed no evidence of invasion to subepithelial tissue. Re-biopsy from the site of urethral stricture revealed squamous cell carcinoma in situ. Under the diagnosis of urethral carcinoma cTisN0M0, urethrectomy of anterior urethra with perineal urethrostomy was performed. Histopathological diagnosis was squamous cell carcinoma of the urethra pTis and surgical margins were negative. The patient reported complete urinary continence, normal erections and ejaculation from his urethrostomy. He showed no evidence of recurrence at 28 months after surgery.
