RESUMEN

OBJECTIVE: Compare the capacity of the PSA density (PSAD), Free PSA percentage ( percentFPSA) and PSA transition zone density (PSATZ) in improving the sensitivity and specificity of the PSA to detect prostate cancer (PCa) in men with a PSA between 4 and 10 ng/mL. MATERIALS AND METHODS: One hundred and forty five men with PSA between 4 and 10 ng/mL were prospectively studied. Blood collection for the total PSA and free PSA was performed as well as transrectal ultra-sound with prostate biopsy and measurement of the total prostate volume (TPV) and transition zone volume (TZV). Patients with initial negative biopsy were followed and the prostate biopsy was repeated in those that presented PSA increase. The capacity of the PSAD, percentFPSA and PSADTZ in improving the sensitivity and specificity pf the PSA test to the detection of the PCa was assessed by univariate and multivariate analyses and through the ROC curve. RESULTS: Of the 145 patients, 38 (26.2 percent) had PCa and in 107 (73.8 percent) a benign prostate disease was diagnosed. No difference among the PSAD, percentFPSA and PSADTZ was found. The multivariate analysis showed that the PSADTZ, percentFPSA, TZV and age were those more powerful and highly significant PCa predictors. CONCLUSION:The determination of percentFPSA and PSAD can allow a better discrimination between PCa and benign disease that the isolated use of PSA. The combination of PSADTZ, percentFPSA, TZV and age promote a high accuracy for PCa detection.

RESUMEN

We describe a modification of the cadaveric prolapse repair and sling - CaPS technique that uses the sling surgery principles to correct grade IV cystocele. In this modification, the central and paravaginal defects reconstitution are performed using cadaveric fascia lata fixed over rectus abdominis muscle, eliminating the need of pubic fixation by screws, as proposed by the original technique. The modification described, besides presenting the benefits of CaPS, i.e., not using impaired tissues to reconstruct vesical support, and lower risks of perineal hypercorrection, also reduces the probability of complications of bone fixation
