[Tumors of the male urethra. A study of 7 cases]

To study the epidemiological, diagnostic and therapeutic features of primary tumors of the male urethra. In this retrospective study we evaluate 7 cases with tumors of the male urethra seen at our department over a period of 16 years [1989 -2005]. The following parameters were studied: the age of the patients, their medial history, clinical signs and symptoms, imaging and treatment modalities used and follow up. The patients' mean age was 56.1 years. Medical history revealed episodes of urethritis in 4 cases and treatment of cervico-urethral strictures in 4 cases. All patients complained of chronic irritating and obstructive symptoms - most patients presented with more than one symptom. Acute urinary retention was found in 5, bleeding per urethram and pyuria in 5 cystourethrography and confirmed by urethrocystoscopy and biopsy. All our patients were found to have squamous cell carcinoma. The tumor was localized in 6 patients. Treatment consisted endoscopic transurethral resection in one patient. Two patients were subjected to surgery. One of them with a stage T3N0M0 tumor of the prostatic urethra underwent urethrectomy in combination with cystoprostatectomy followed by urinary diversion [Coffey], while the other patient with a tumor at the bulbomembranous urethra [stage T4N0M0 with scrotal invasion] was subjected to penectomy and orchidectomy combined with perineal urethrostomy. Both these patients received adjuvant radiotherapy. Excision of a penile phlegmon was carried out in 3 patients. In one of them a urethral stent was left indwelling, while two were subjected to cystostomy. Due to bilateral lymphatic invasion, the remaining patient received preoperative radiotherapy, but he died three months later due to lung metastases. None of our patients received chemotherapy. Mean follow up was 9.5 months. At the end of the follow-up period 3 patients [one treated endoscopically and the two patients that had been subjected to surgery] were disease-free, while one patients had died and the 3 remaining ones were lost to follow up. Despite the availability of a variety of treatment modalities, tumors of the male urethra still have a poor prognosis. Due to their rarity, it is difficult to properly evaluate the treatment options which mainly depend on the tumor stage and whether or not there is lymphatic invasion

Carcinoma da uretra feminina / Carcinoma of the female urethra

O carcinoma da uretra feminina é uma neoplasia de grave prognóstico. Seu tratamento está relacionado ao estadiamento e à porçäo uretral comprometida. A experiência mundial é pequena com estes casos, mas os autores adiantam que possivelmente a melhor forma de tratamento, no momento seja a utilizaçäo de radioterapia para os tumores iniciais e radioterapia pré-operatória seguida de exenteraçäo pélvica nos casos mais avançados
