Two cases of Primary Urethral Cancer which was f ound in each one of male and female in our department are reported, as following. Case I ; Patient, 72-year-old, m a l e, recognized hematuria and painless tumor in the root of penis, and visited our clinic. From the X-ray film, anterior part of urethra was pushed up, the cavity at that part was narrow and its outline was irregular. At the part of bulbous, the cavity was expanded and shadow deficit was found. Then amputation of the penis with groin dissection was p erformed and cut-end of the urethra was opend out in the perineal part. Histologically it was diagnosed as squamous cell carcinoma. In this country 31 cases of urethral cancer have been reported including this case. Now the patient is still in health and has no symptom of relapse after 3 mon t hs operation. Case II Patient, 58-year-old, female, since around 2 years ago recognized external genital bleeding, and she visited our clinic whith a chief complaint of sudden urinary retention. In the external genitalia no lesion was found but from 1 cm over external urethral orifice over the whole urethra bundle-shaped induration was felt. From X-ray film the whole urethra was noted to have a deviation to the right and irregular outline. Then total urethro-cystectomy and ureterosigmoidostomy was done. The p rognosis after the operation was good. Alkaline treatm e nt had been effective in preventing hyperchloremic acidosis which occured after her leaving hospital. Histological diagnosis w a s columnar epitheliar carcinoma. According to the classification of Ehrendorfer it was categorized II Urethral-type which is extremely rare. In our country only 8 cases were described clearly and the cases o f female primary urethral cancer, including this case, are 88. In case of diversion of urinary tract, we will appreciate cutaneous ureterostomy, nephrostomy and ileocystoplasty instead of ureterosigmoidostomy which produce a fetal complication such as hyperchloremic acidosis based upon our experience and other reports .
