[Operative treatment of vesico-vaginal fistulae]. / Die operative Behandlung von Blasenscheidenfisteln.

During a period of 16 years, 40 cases of vesico-vaginal fistulae were treated. In 21 of the cases a fistula closing operation could be carried out, 8 vaginally and 13 suprapubically. Out of the 40 cases 19 were cured. In most cases the fistula was approached abdominally and closed by a single-layer method, leaving the vaginal defect open for drainage. This method was suitable for all types of vesico-vaginal fistulae, independent of their size and location but especially suitable for fistulae occurring after irradiation where severe tissue changes had occurred. Urinary diversion is often the only way of helping these patients and the indications for the various types of diversion are discussed.

[Computed tomography as an aid in the differential diagnosis of radiolucent stones and tumors of the upper urinary tract]. / Die Computertomographie als Hilfsmittel bei der Differentialdiagnose nichtschattengebender Konkremente und Tumoren der oberen Harnwege.

The difficult differential diagnosis of urothelial tumors and nonopaque calculi of the upper urinary tract has been considerably improved by the introduction of computed tomography (CT) in urological diagnosis. Nonopaque calculi although urographically not visible can be determined by CT. Usually urothelial tumors can be traced by CT without invasive methods. In case of doubt in addition to the primary scan a so called flow-study, after application of contrast medium, will furnish additional information. The diagnostic facilities provided by CT are illustrated in 18 cases.

[A comparison of different methods of measuring bleeding time (author's transl)]. / Vergleichende Untersuchungen zur Bestimmung der Blutungszeit

Two methods of determining bleeding time (Ivy's and Duke's) were compared using a standardized method. Skin cuts were made with either a disposable scalpel or a precision plunger. Ivy's method gave results which were markedly superior to those with Duke's. It was, furthermore, shown that reproducibility of two successive determinations in the same person largely depended on the experience of the investigator. Best results were obtained using the precision plunger and automatic collection of blood. But even when these were used, there were frequent deviations of more than 20% in duplicate samples.
