Correlation of Histologic Types With Clinical findings and Transrectal Ultrasonographic Pictures in Benign Prostatic Hyperplasia / 대한비뇨기과학회지

Tissues obtained by transurethral prostatectomies were evaluated histologically and correlated with the clinical findings and the transrectal ultrasonographic pictures of 104 patients with benign prostatic hyperplasia (BPH). The patients were divided into 3 groups according to the following histology. predominantly glandular types (30 patients), predominantly stromal types (35 patients) and mixed types which have equal proportions of glandular and stromal hyperplasia (39 patients). The average age was highest in the glandular group. Postoperative obstructive symptom scores were significantly lower in the stromal type as compared to the glandular and the mixed type. The maximal flow rates at three months following the operations were highest in the stromal type. In comparison of the histologic findings with preoperative transrectal echographic pictures, the transverse and the longitudinal diameter of the transitional zone were significantly lower in the stromal type than in the glandular and the mixed type. The weight of transitional zone was significantly smaller in the stromal type than in the glandular and the mixed type. The echogenicity showed hyperechoic and isoechoic pattern in the stromal and the mixed type and hypoechoic and isoechoic pattern in the glandular type. The echographic homogeneity, the frequency of prostatic calculi and cyst formation, and the margination of the transitional zone did not show any significant difference among each group. In conclusion, the histologic types of BPH have correlations with the clinical findings and the transrectal ultrasonographic pictures. Furthermore precise interpretation of the histologic types of BPH by transrectal ultrasonography will be helpful in decision making about the treatment modality and in prediction of the clinical progress after some treatment for the patients with BPH.

A Case of Huge Retroperitoneal Lipoma / 대한비뇨기과학회지

Retroperitoneal lipoma probably constitute the group of the most massive solid abdominal tumors; their etiology is unknown; their symptoms insidious; and recurrence and sarcomatous change frequent. The clinical diagnosis was made by clinical symptoms, physical findings and radiologic evaluation such as intravenous urography, ultrasonography, computed tomography, angiography and so on. Abdominal CF scan provided clinically the most useful information regarding the state of tumors and also their effect on adjacent structures and shows homogenous appearing fat tissue with a low attenuation coefficient identical to that found in the subcutaneous fat. We present a case of treatment for a huge retroperitoneal lipoma in a 46-year-old man.

A Case of Leiomyoma of the Kidney / 대한비뇨기과학회지

Renal leiomyoma, a rare benign tumor, is a challenging diagnostic and therapeutic condition. The preoperative diagnosis of renal leiomyoma is very difficult, and the only definite method to distinguish between a leiomyoma and other renal tumor is postoperative microscopic evaluation. We report a case of leiomyoma of the kidney which was managed by radical nephrectomy under the impression of malignant renal mass which was incidentally found by ultrasonographic examination for health check in a 43-year-old woman.
