摘要:

SUMMARY1The results of immediate Wilson Hey prostatectomy in 150 cases of acute retention are reported.2An overall mortality rate of 10 per cent. is considered satisfactory in this unselected group of patients.3Infection remains the chief cause of death, and suggestions are made to reduce it in this type of case.4It is preferable that operation should be performed before acute and particularly before chronic retention develops. The vast improvement in technique and results of operation in recent years should convince the general practitioner and the public of the necessity for early advice and treatment. In this way only can the mortality and morbidity of prostatectomy be reduced.

摘要:

SUMMARYFive hundred urinary calculi have been examined for direct or indirect evidence of radial striation. Such evidence is found in 42 per cent. of the calculi. Radial striation is limited to areas composed of calcium oxalate monohydrate, uric acid, or calcium acid phosphate dihydrate. It does not occur in areas of mixed composition. Radial striation is always associated with concentric lamination, but the reverse is not the case.Radial striation is shown by X‐ray diffraction techniques to be a consequence of the arrangement of the minute crystals which form the calculus; all the crystals tend to have a particular crystallographic direction radially placed in the calculus. In the case of calculi composed of calcium oxalate monohydrate the particular direction is thebcrystallographic axis; in the case of calculi composed of calcium acid phosphate dihydrate it is theacrystallographic axis.The pathogenesis of radially striated calculi is developed from information on related concretions. The mucinous layer present on calculi is regarded as necessary for the development of this type of calculus: it allows diffusion of ionic groups but prevents disturbances in the process of crystallisation and so permits oriented growth to occur. The mucinous layer is continuously incorporated into the calculus as its “organic matr

摘要:

SUMMARYExperimental vesicular calculi were produced in albino rats by feeding the animals on a diet deficient in vitamin A. The distribution of mineral salts in these calculi was studied by microradiography. The nature of the mineral salts was determined by X‐ray diffraction methods. Calculi with a layered deposition of the mineral salts gave an X‐ray diffraction pattern characteristic of hydroxylapatite. Such layered calculi are found both among experimental and spontaneous calculi. Their genesis is briefly discus
