[Follow-up after radical prostatectomy in prostatic cancer. CT: normal findings].

We retrospectively reviewed the CT findings of 18 patients submitted to radical prostatectomy for prostate cancer. CT follow-up studies showed the bladder base in retropubic location in all 18 patients. Two patients had local recurrences, while no evidence of local recurrence was found in 16 patients. The following CT findings were observed in the latter group: a) bladder to rectum adhesion in 2 cases (13%); b) a complete transverse bar of soft tissue density between bladder and rectum in 9 cases (57%); c) an incomplete rectovesical bar in 6 cases (40%). The transverse bar was already apparent on the first pelvic CT scan performed within two weeks in 3 cases for surgical complications. In two local recurrences some dense tissue was demonstrated distorting rectovesical lateral triangle fat. To conclude, since a complete or incomplete horizontal bar of soft tissue structures is usually depicted in the rectovesical space, these structures should not be misdiagnosed as local tumor recurrences.

[Cystectomy and internal urinary diversion in bladder neoplasm. Role of CT in the follow-up].

Fifty-seven patients, with prior cystectomy and continent urinary diversion for transitional cell carcinoma of the bladder, were evaluated with CT. Forty-two of them presented ureterosigmoidostomy and 15 orthotopic ileal bladder. The CT appearance of the normal post-cystectomy pelvis is emphasized. Both early and late surgical and neoplastic complications were detected. Early surgical complications, including urinary fistulae, urinomas, seromas, lymphoceles, and abscesses, were diagnosed over a 6-month postoperative period. Late surgical complications included hydroureteronephrosis, calculosis, and pyelonephritis. Hydroureteronephrosis, due to stenosis of the ureteral anastomosis, was the most frequent complication. All such neoplastic complications as local recurrence, lymphnode distant metastases, were identified. In 83% of cases they were observed over a 2-year postoperative period. Distant metastases in the upper abdomen were never detected. The authors' experience suggests the following as the optimal follow-up: a) CT examination over a 6-month postoperative period; b) yearly CT examinations and urography over 4 postoperative years; c) yearly US examination over the first 2 years after surgery, to depict renal pelvis dilatation. Skeletal scintigraphy is often necessary to detect metastatic bone lesions. It should be performed no later than 2 years after cystectomy.

[Maximal mid-exiratory flow (MMEF) in the evolution of the respiratory functional patter of silicosis. (author's transl)].

A follow up study of VC, FEV and MMEF was performed by the authors in forty silicotic patients, mainly in order to find out if MMEF were more sensitive than VC and FEV 1 IN detecting respiratory function impairment in the follow up of silicosis. In patients with moderate bronchial obstruction, a statistically significant difference was found between themean values of MMEF measured in two different instances: such a finding suggests a greater MMEF reduction in the early stages of silicosis. In 22 subjects with moderate respiratory function impairment (VC and FEV1 less than or equal 40% predicted values), MMEF was found to be, percentually, more decreased than FEV1: the difference was statistically significant. It is therefore concluded that MMEF changes in the follow up examination of silicosis are more sensitive than other functional indexes.
