結核膀胱のレ線学的研究 第1篇:静態時膀胱,特にFreudenberg 現象に就て

Abstract

The f phenomenon proposed by the author referring to the cystogram of tuberculous bladder, viz. a vesical area measure planimetrically appearing smaller on the side of an involved kidney than that of a normal kidney, was studied in 121 cases of tuberculous bladder resulting from unilateral renal tuberculosis. 1) A normal bladder seldom showed a completely identical picture on the right side and on the left side, but its right area appeared slightly wider than the left. 2) The f phenomenon in cases of tuberculous bladder occurred more frequently and more clearly as an irrigated medium increased in amount, while in cases of normal bladder the difference of area between the right side and the left side was hardly recognized as an injected medium increased in amount. 3) It was to be noted that the f phenomenon appeared far more frequently (55.7 %) than the so-called Freudenberg's phenomenon (35.2 %), which is characterized by an inclined outline of the cystogram and a reduction of the longest perpendicular drawn from the bladder edge to the median line on the involved renal side. 4) The f phenomenon was observed more frequently o n the left side (68.7 %) than on the right side (40 %) and most often in cases of 200300 cc vesical capacity (67 %). In connection with the invated grade of renal tuberculosis it occurred most frequently in the moderately advanced stage (68 %), then in the end-stage (55 %), and only occasionally in the early stage (27 %). 5) There were f ound only 8 cases (9 %) presenting the ureterovesical backflow on the side of affected kidney, so far less frequently than the f phenomenon, and in 6 of these cases with ureterovesical backflow the f phenomenon occurred also simultaneously.
