Unlabelled: This study compares ultrasonographic prediction of prostatic volume and surgical exerese. A total of 200 prostates have been measured by the same echographist, operated upon by the same surgeon, and stratified for histology, surgical technique and weight. Adopting the general formula: Surgical volume = D1 x D2 x D3/x the surgical volume is calculated by a simplified and complete definition for a denominator giving the most accurate prediction., Conclusions: a. the glands of more than 60 cc could be calculated by the classical formula of ellipsoid pi x D1 x D2 x D3/6, simplified to D1 x D2 x D3/2, with a 21% standard deviation error from the surgical volume; b. medium-sized prostates (20-60 cc) could be calculated by the formula: D1 x D2 x D3/3 with a 21% standard deviation; c. prostates smaller than 20 cc, a series which included all reoperations for remnants or recurrence, could be calculated with the same proposed formula with a 22% standard deviation, while the classical ellipsoid formula led to a 56% standard deviation error. No mathematical formula based only on three prostatic diameters is reliable to assess true parenchymal weight.

This technique has been applied to 224 female patients over 9 years with a mean follow-up to the last control of 2 years 3 months. The sub-urethral fold of the fascia, the inferior and infero-lateral aspects of the urethra are dissected, the length and the width of the tube are restored by direct resuture, the sub-urethral fascia is doubled by overlapping. No suspension nor foreign tissue. Genito-urinary ptosis is treated by the same time. Application to stress incontinence, diverticulae, abscesses, periurethritis and a few cases of non malignant pathology. In stress incontinence, selected by suprapubic expression test, full success in 76.3%, primary failure in 5.4% and imperfect result with no permanent or necessary padding in 18.2%. In these imperfect results and failures as well as in periurethral pathology the importance of relapsing inferior of the low tract suggests that sexual infections be more investigated and that mechanical causes of infection, such as reflux be more operated on. On the 224 cases, 1 fistula and 1 urethral avulsion, in particular conditions which do not affect the general principle. No fistula in 12 cases of urethral diverticulae and abscesses. The suprapubic expression test in simple and valuable in selecting before and testing after operation the static mechanical incontinence.

Ingested asbestos is mainly excreted in the urine. Marked impregnation of bladder neck in a patient working in an asbestos factory was diagnosed initially as a tuberculosis lesion on the granulomatous histologic appearance. Asbestos fibers were counted by electron microscopy. This appears to be the first case of this type reported and possible causal relations and histopathologic findings are discussed. Also reported is a patient with prostatic cancer, and chronic pulmonary asbestosis, treated by adenomectomy using an upper approach 15 years previously. The cancer was of the prostate transitional cell type. A causal relation could not be proved but other such cases should be investigated, to determine a possible link between the lesion and industrial fibers.
