A Study on the Differential Diagnosis of Upper Urinary Tract and Lower urinary Tract Infection by Urinary Lactate Dehydrogenase lsozyme Assays / 대한비뇨기과학회지

Urinary lactate dehydrogenase (U-LD) isozyme assays were performed by cellulose acetate electrophoresis on the patients with clinically proven upper urinary tract infection (U-UTI) (N=21), lower urinary tract infection (L-UTI) (N=l5) and undetermined site of urinary tract infection (N =l4) as well as normal controls(N=l5). The results of this study are summarized as follows: * Total U-LD in normal controls (73.8 +/- 37.4 U/1) was significantly lower than in patients with upper UTI (145.9 +/- 86.8 U/I(p<0.01) or lower UTI (126.3 +/- 88.4 U/I) (p<0.05). * In normal controls and patients with L-UTI, LDI and LD2 predominated ('fast zone' pattern), and in patients with U-UTI, mainly LD5 and LD4 predominated('slow zone' pattern).

A Case of Pleomorphic Rhabdomyosarcoma of an Adult Prostate / 대한비뇨기과학회지

Rhadomyosarcoma of the prostate is relatively rare and highly malignant condition. Three major categories of rhabdomyosarcoma exist, which should be kept clearly separated: pleomorphic, embryonal, and alveolar Pleomorphic rhabdomyosarcoma is actually the least common of the three categories. It arises from myotome-derived skeletal muscle and occurs almost exclusively in adults. We make the unequivocal diagnosis of pleomorphic rhabdomyosarcoma only if we can detect cross striations in some of the tumor cells. Herein we experienced a pleomorphic rhabdomyosarcoma of the prostate which is generally not found in the urogenital area and reviewed literature briefly.

A Case of Inverted Papilloma of Urinary Bladder / 대한비뇨기과학회지

Inverted papilloma of the urothelium is a rare, benign polypoid lesion which has typical histologic findings. Microscopically, a nonpapillary urothelium covers the surface from which cords of same epithelium invert and extend deep into the core in an anastomosing pattern, always maintaining its benign histological characteristic. Recently, we experienced a case of inverted papilloma of the bladder in 23-year-old male.
