Authors experienced a case of torsion of spermatic cord recently and reviewed the literatures. The patient was a 33 year-old male with chief complaints of sudden onset on left scrotal swelling and testicular pain. Physical examination was not significant except positive Prehn`s sign on the involving side of testicle. Under the diagnosis of torsion of spermatic cord, he was performed of left orchiectomy and the opposite side orchiopexy.

Primary tumors of the ureter are usually malignant and rare, a few are benign. Benign tumors arising from mesoderm are especially rare. But, recently the incidence rate was progressively increased due to developed methods of diagnostic procedures. We herein report a case of ureteral polyp in the left ureteropelvic junction with a brief review of literatures.

PURPOSE: We wanted to investigate the incidence of posterior diaphragmatic defect on chest CT in various age gropus and its lateral chest radiographic appearances. MATERIALS AND METHODS: The chest CT scans of 78 patients of various ages with posterior diaphragmatic defect were selected among 1,991 patients, and they were analyzed for the incidence of defect in various age groups, the defect location and the herniated contents. Their lateral chest radiographs were analyzed for the shape of the posterior diaphragm and the posterior costophrenic sulcus. RESULTS: The patients' ages ranged from 34 to 87 with the tendency of a higher incidence in the older patients. The defect most frequently involved the medial two thirds (n= 49, 50.4%) and middle one third (n=36, 37%) of the posterior diaphragm. The retroperitoneal fat was herniated into the thorax through the defect in all patients, and sometimes with the kidney (n=8). Lateral chest radiography showed a normal diaphragmatic contour (n=51, 49.5%), blunting of the posterior costophrenic sulcus (n=41, 39.8%), focal humping of the posterior diaphragm (n=7, 6.8%), or upward convexity (n=4, 3.9%) of the posterior costophrenic sulcus on the affected side. CONCLUSION: The posterior diaphragmatic defect discovered in asymptomatic patients who are without a history of peridiaphragmatic disease is most likely acquired, and this malady increases in incidence according to age. An abnormal contour of the posterior diaphragm or the costophrenic sulcus on a lateral chest radiograph may be a finding of posterior diaphragmatic defect.

PURPOSE: The prognostic factors influencing the survival rate in patients with renal cell carcinoma were evaluated. MATERIALS AND METHODS: An analysis was performed on 102 patients with renal cell carcinoma who underwent a radical nephrectomy from January 1995 to June 1999. The survival rate according to each prognostic factor such as the 1997 TNM stage, the size, cell type and nuclear grade of the tumor and the presence of symptoms at the point of diagnosis, age and gender, and tumor location was analyzed using the Kaplan-Meier method. The statistics was determined by the log-rank test of a univariate analysis and the Cox proportional hazards model of multivariate analysis. RESULTS: Univariate analysis showed that the TNM stage, size and nuclear grade of tumor, and the presence of symptoms at the point of diagnosis had a significant influence on survival rate of patients with renal cell carcinoma. The tumor cell type, age and gender, the location of the tumors had little statistical significance. Multivariate analysis showed that a distant metastasis was the most significant prognostic factor followed by nuclear grade of the tumor cell, T stage, the presence of symptoms at the point of diagnosis, and lymph node metastasis in this order. CONCLUSIONS: The TNM stage, nuclear grade of the tumor and the presence of symptoms at diagnosis are important prognostic factors in renal cell carcinoma. Analyzing these prognostic factors will be useful as a treatment modality, follow up and prognosis of patients with renal cell carcinoma.
