True hermaphroditism is a rare disorder or sexual development in which both ovarian and testicular tissue exist in a same individual. Author experienced a case of true hermaphroditism in a 15 years old patient, reared as a male who had an ovotestis in the right side and ovary in the left, managed by resection of testicular tissue and feminine genitoplasty.

We analyzed the composition of urinary stones using chemical analysis method. From 1985 to 1995, 495 urinary calculi were eligible for stone analysis. Forty six per cent of the stones were composed of single chemical component, and pure calcium oxalate stone was the most common type of the stones consisting 34.9% of all stones, followed by 23.8% of mixture of calcium oxalate and calcium phosphate, and 92.7% of the stones had calcium component. Calcium oxalate crystal was found in 82.6% of the stones, calcium phosphate in 50.5%, ammonium magnesium phosphate in 26.7%, uric acid in 11.3% and cystine in 0.4%. Nation-wide extension of this study using chemical analysis will be mandatory for a proper assessment of the stone composition of Koreans and for planning of the proper management strategies for urinary stones in Korea.

A study was done to evaluate the diagnostic value of ultrasonography on acute scrotum patients. During the last three years, 25 patients were managed at Cheju Medical Center, eight of them were testicular torsion patients including one cryptorchid testicular torsion. one torsion of appendix testis, 11 acute epididymitis and 5 testicular rupture due to blunt scrotal trauma. Ultrasonography revealed enlarged testis and epididymis in all of the 8 testicular torsion patients and 7 of them showed inhomogeneously decreased echogenecity of the testis and epididymis. All acute epididymitis patients showed enlargement of the epididymis, and inhomogeneously decreased echogenecity was found in 8 of them. But testicular echogenecity was normal in all of the acute epididymitis patients and enlargement of the testis was found in two. All of the 5 testicular rupture patients showed irregular hypoechoic portions in the testicle and distorted testicular morphology, and linear fracture lines of the testis were found in two. We could suggest that scrotal ultrasonography is useful for the early differential diagnosis of the acute scrotum, especially when scrotal radioisotope scan is not available.
