[Fine-needle aspiration cytology in the diagnosis of prostate cancer. Results]. / Citología por aspiración con aguja fina en el diagnóstico del cáncer de próstata. Resultados.

OBJECTIVE: To demonstrate the utility of fine needle aspiration biopsy in the diagnosis of prostatic tumors, basically carcinoma of the prostate. METHODS/RESULTS: The clinical records of 497 patients who underwent fine needle aspiration biopsy were reviewed. Age, skin color, clinical diagnosis by DRE, transrectal core biopsy, correlation between clinical and histological diagnosis, distribution according to type of adenocarcinoma, correlation between cytological and histological diagnosis, and complications were analyzed. Of the 497 patients, 162 had histological confirmation. Of these 162 patients, the Galen and Gambino statistical method was utilized in 132 which represented the true negatives and positives. Sensitivity was 86%, specificity 96%, positive predictive value 91%, negative predictive value 93%, and efficiency was 92%. The complication rate was low. CONCLUSIONS: Fine needle aspiration biopsy is a safe and efficient diagnostic method in prostatic tumors and causes minimal discomfort to the patient.

[Well differentiated mucus-producing adenocarcinoma of the right renal pelvis. Presentation of a case]. / Adenocarcinoma mucoproductor bien diferenciado de pelvis renal derecha. Presentación de un caso.

OBJECTIVE: To present a rare case of well-differentiated mucus-producing adenocarcinoma of the renal pelvis. METHODS: Patient history, the results of the complementary tests after surgery, treatment and anatomopathological findings are presented. RESULTS/CONCLUSIONS: Well-differentiated mucus-producing adenocarcinoma of the renal pelvis is rare and is often associated with lithiasis, a long history of obstruction and inflammation. Nests of tumor cells surrounded by abundant mucus is a characteristic histological finding in this tumor type.

[Asymptomatic bacteriuria or "detected" bacteriuria in the female. Incidence in our health area]. / Bacteriuria asintomática o bacteriuria "detectada" en la mujer. Incidencia en nuestra área de salud.

OBJECTIVES: To determine the incidence of asymptomatic bacteriuria in women consulting at our hospital and its relationship with other chronic diseases. METHODS: A cross-sectional study was conducted on 735 women who had consulted at our hospital from February to September, 1996. Urinary sediment, serial urine culture, serum urea and creatinine values were analyzed. Patient records were reviewed to obtain pertinent data for the study. RESULTS: The incidence of asymptomatic bacteriuria was 8%; 47.4% of the cases were women over 60 years of age. E. coli was identified as the causative organism in 77.9% of the urine cultures. Diabetes mellitus was the most frequent associated chronic disease (27.1%). The incidence of renal damage was not statistically significant and was not directly related with bacteriuria. CONCLUSIONS: We emphasize the importance of performing a urine culture when leukocyturia is detected. The incidence of asymptomatic bacteriuria increases with age. E. coli was the most frequent causative organism. Diabetes mellitus was the most frequent associated chronic disease. The incidence of renal damage was not statistically significant.
