Abstract

Urinary lithiasis is one of the most common disease of the urinary tract. It occurs or frequently in men thanin women but rare in children and in blacks; a familial predisposition is often encountered. Ureteral stonesoriginate in the kidney. Gravity and peristalis contribute to spontaneous passage into and down the ureter.Ureterovesical junction is the most frequent lodging site of stone. In our hospital one case of ureteral casestone and giant urethral stone were found respectively and they were confirmed by radiological examination andsurgery on Aug. 1978 and Jan. 1979. Uretral case stone which had been introduced and named first by kiyonobu Tariand Kikjiro So in 1972 was very giant unusually. It may be the only one till now. Our patient was 36 years oldfemale who has been suffered from intermittent right flank pain for 10 years. On KUB giant cylindrical radiopaqueshadow was shown on RLQ extended to right minor pelvis and this was confirmed as a stone by retrograde ureteralcatheterization. A stone measured 13cm x 1.5cm was found above the ureterovesical junction during operation.Follow up excretory urogram one year after operation showed no functional improvement of right kidney. Urethralstone is also unusual urinary lithiasis. This 60 years old male patient has been suffered from nontender palpablehard mass on scrotal area and intermittent urinary retention. When urinary retention was occurred it was relievedby manipulation of the mass by himself. On plain filn oval shaped giant radiopaque shadow was shown on cavernousurethral region. On urethrocystogram anterior urethra was opacified, but posterior urethra and bladder were notopacified and mulitiple fistulous leadkage was identified. A stone measured 6.5cm Ã— 3.5cm was found in cavernousurethra during operation.
