Staphylococcus infection was the most common organism found in infection of athletics, and tuberculosis (TB) was rare. Although genitourinary tuberculosis (GUTB) was the most common subtype of extrapulmonary tuberculosis (EPTB) in the past, it was recently reported to account for less than 0.5% of all patients with EPTB and 1.5% of all patients with pulmonary tuberculosis (TB). And, there are few cases reported about concomitant tuberculous infection of testis and prostate. Pubic pain is a commo

The incidence of horseshoe kidney is about 1 in 400 cases. The presence of Wilms' tumor with a horseshoe kidney is unusual, and the occurrence of Wilms' tumor in a horseshoe kidney is estimated at 0.4 to 0.9% of all Wilms' tumors. We report the case of a 5-year-old boy who presented with a stage IV Wilms' tumor in a horseshoe kidney. The patient was treated with preoperative chemotherapy followed by surgical resection and adjuvant chemotherapy. This case illustrates the role of preoperative chem

Statin administration reduced PSA and PV in BPH patients. This finding may imply the improvement of lower urinary tract symptoms and prevention of cardiovascular disease and chemoprevention of prostate cancer with statin treatment.

The HCl pretreatment model was a preferable murine bladder tumor model for evaluating further therapeutic interventions.

Purpose We investigated potential difference in the clinical features of hospitalized female acute pyelonephritis (APN) patients with and without diabetes mellitus (DM). The additional purpose of the study was to determine whether HbA1c has a role in predicting clinical outcome in terms of morbidity compared with those considered to have normal glycemic control in female APN patients with DM. Materials and Methods Among the female patients who received inpatients care due to APN from January 201

= Abstract = Purpose: We investigated the predictive factors in patient with prostate cancer diagnosed by repeat prostate biopsy, where initial prostate biopsy results were negative for malignancy. Materials and Methods: Between March 2000 and June 2007, 1280 men with suspected prostatic cancer underwent transrectal ultrasound guided needle biopsy of the prostate, with 148 (11.6%) diagnosed as having prostate cancer. Of 1132 men whose biopsy results were negative for malignancy, 655 whose prosta

Purpose: An animal model with experimental uremia is an important research tool for the study of pathophysiological events that take place during chronic renal failure. Among the several techniques of making uremic models, the two-stage 5/6 nephrectomized rat model is the most popular method, but this modality has some disadvantages. The aim of this study was to simplify the complicated method for experimental uremic animal models in the rat. Materials and Methods: Forty Sprague-Dawley rats were

Lymphoepithelioma was originally described as a neoplasm in the nasopharynx. Tumors with histologic features similar to those of nasopharyngeal lymphoepithelioma have been identified in anatomic sites other than the nasopharynx, such as the salivary gland, lung, thymus and stomach; these tumors have been termed lymphoepithelioma-like carcinoma(LELC). The etiology and pathogenesis of this neoplasm in the renal pelvis is not clear. We have experienced a case of lymphoepithelioma-like carcinoma of

The occurrence of bladder tumors in the first 2 decades of life are rare neoplasias. Transitional cell tumors of the bladder are extremely a rare clinical disease entity. Here, a case of a papillary urothelial tumor in a 5-year-old girl is reported, with a brief review of the literature. Histologically, the tumor was a solitary and papillary urothelial tumor of low malignant potential(by WHO and the ISUP).

Purpose: We evaluated the rate of prostate cancer detection according to the region and number of biopsies in patients with an elevated level of serum prostate-specific antigen (PSA). Materials and Methods: Transrectal ultrasound (TRUS) guided prostate biopsies were performed at 12 regions, using the standard sextant, with an additional 6 cores from the far lateral peripheral zone, in 178 men with an elevated PSA level, and with no suspicious lesions of prostate cancer on digital rectal examinat

The incidence of horseshoe kidney is about 1 in 400 cases. The presence of Wilms’ tumor with a horseshoe kidney is unusual, and the occurrence of Wilms’ tumor in a horseshoe kidney is estimated at 0.4 to 0.9% of all Wilms’ tumors. We report the case of a 5-year-old boy who presented with a stage IV Wilms’ tumor in a horseshoe kidney. The patient was treated with preoperative chemotherapy followed by surgical resection and adjuvant chemotherapy. This case illustrates the role of preoperative chem

Endometriosis represents extrauterine nonneoplastic endometrial tissue. It is most commonly diagnosed in women of childbearing age, with a peak age of 40 to 44 years. The incidence of genitourinary involvement ranges from 1% to 2%. Ureteral endometriosis is a rare entity, and its diagnosis requires a high index of suspicion. We report a case of ureteral endometriosis in a 44-year-old multiparous woman with a brief review of literature. (J. Korean Continence Society 2005;9:142-145)
