A Case of Incidental Testicular Teratoma Found during Hydrocelectomy / 대한비뇨기과학회지

Testicular teratoma contains more than one germ cell layer in various stages of maturation and differentiation. The teratoma occurs at all ages but is most common in the 25-30 year age group. It is relatively infrequently seen in childhood and infancy. In these age group, teratoma is a benign tumor. Recently, we experienced one case of incidental testicular teratoma during hydrocelectomy in 22 month-old child, The hydrocele is frequently associated with teratoma under age 4 years and is the most common misdiagnosis. So we report this one case of testicular teratoma with review of related literatures.

153 Cases of Laser Lithotripsy / 대한비뇨기과학회지

The pulsed laser lithotripsy has been used in the treatment of urinary calculi. We treated 153 patients of stones, via the pulsed dye laser(Technomed Pulsolith) with 7.5 and 6.5 F. rigid ureteroscope between January 1992 and January 1995. Stones were in bladder(4 cases), upper ureter(17), mid ureter(31) and lower ureter(101). The laser lithotripsies were applied for impacted stones and relatively large stones(more than 6 mm) The success rates according to location were 47%(8/17) in upper ureter, 77%(24/31)in middle ureter, 95%(96/101)in lower ureter and 100%(4/4) in bladder and mean success rate was 86% (132/153). There were 21 failures due to upward migration(9 cases), poor visual field(7), laser resistant stone(3) and malfunction of laser(2). Complications were showed in 28 cases that were gross hematuria(16 cases), ureteral perforation(6), fever(4) and ileus(2), but most of them might be related to ureteroscopy rather than laser, and all of them were resolved with conservative management. So laser lithotripsy is safe and effective method of middle and lower ureteral calculi, and upward migration of stones, the major cause of failure may be resolved by use of extracorporeal shock wave lithotripsy and flexible ureteroscope.

A Case of Urethral Diverticulum Combined with Giant Stone / 대한비뇨기과학회지

A case of one of the largest stone in a giant penile urethral diverticulum which disturbed voiding and ejaculation was responded with review of some literatures.

A Case of 47XYY Syndrome with Azoospermia / 대한비뇨기과학회지

The XYY syndrome is a rare entity, which is a phenotypic man with a 47 XYY It was first reported by Sandberg and associates in 1961. The XYY individual is seldom detected during childhood or even in adult because the features of XYY syndrome are often subtle and not overtly suggestive of a chromosomal abnormalities. We have reported a case of XYY syndrome associated with absence of pubic and axillary hair, no voice mutation and azoospermia. Clinical, endocrinologic and genetic studies were presented and theories regarding the etiology of the XYY syndrome were discussed with review of the literature.
