A Case of Retroperitoneal Leiomyosarcoma / 대한비뇨기과학회지

Retroperitoneal tumors are account for fewer than 0.2 % of total malignancies. Retroperitoneal leiomyosarcoma of these are rare and show a tendency toward large size and extensions by infiltration to the adjacent structure. Thus, the most frequent symptoms are palpable abdominal mass and abdominal pain. Early detection and treatment is difficult in retroperitoneal tumor. Aggressive radical surgical excision is treatment of choice. Modern therapeutic modalilty improve the prognosis, but still remained debatable prognosis. we report a case of retroperitoneal leiomyosarcoma in 54-year-old women who was recieved chemotherapy and then surgical removal.

Errors of Prostate Volume between Actual Models and Transrectal Ultrasonographic Measurement / 대한비뇨기과학회지

PURPOSE: To determine the relative accuracy of transrectal ultrasonographic measurement of prostate volume in comparison to actual volume of prostate and its clinical application. MATERIALS AND METHODS: Forty-five benign prostate hyperplasia patients who were undergone transrectal ultrasonography for prostatic volume estimation in Kosin university hospital were selected. Prostate models in equal size with ultrasonographically estimated prostatic size were made and used as model I group. We also made twenty prostate models in different size and used as model II group. We compared measurement of ultrasonographic volume of prostate model with actual volume of prostate model in two groups. RESULTS: In model I group, the most accurate method in estimating prostate volume was variation of the spheroid formula with correlation coefficient of 0.892 and then ellipsoid formula with correlation coefficient of 0.887. In model II group, the most accurate method in estimating prostate volume was ellipsoid formula with correlation coefficient of 0.945 and then variation of the spheroid formula with correlation coefficient of 0.929. CONCLUSIONS: When different volume ranges were considered, it was suspected that ellipsoid formula provided the closest estimate of prostate volume in less than 50cc range and variation of the spheroid formula in more than 50cc range in estimating the prostate volume.

A Case of Papillary Type of Renal Cell Carcinoma after Renal Injury in a Child / 대한비뇨기과학회지

Renal cell carcinoma is an uncommon tumor in children and only 3-5 percent of the renal cell carcinoma occur under age of twenty. Interestingly, some of the patients had a history of trauma occurring shortly before the onset of symptom calling attention to the tumor. In histology of renal cell carcinoma, clear cell type is most common and papillary type is 10-15 percent. The papillary type of renal cell carcinoma is characterized by better prognosis than non-papillary types. We report a case of papillary type of renal cell carcinoma which was detected incidentally after trauma in 13-year-old male patient.
