Recently I have experienced 6 cases of foreign bodies in the urinary bladders in our clinic and I have collected 156 cases of foreign bodies in the bladders from the literature in Japan with our 6 cases until 1932 with the following results.
1. From a standpoint of age, it takes a large percentage of the cases between 21-30 (30%) and the proportion between man and woman is 3:1
2. Variety of the foreign bodies are as follow:
a) Candle and candle-like substances are 20.4%.
b) Rubber catheters are 14.2%.
c) Thin metal manufactured goods are 12.3%.
d) Roots and stems of plants are 10.5% and so on.
3. The courses of foreign bodies into the bladders are of two ways, one is from urethra (120 cases) and another not from urethra (33 cases).
4. Foreign bodies in the urinary bladder by masturbation show 46.6% and by the doctor's fault 10%.
5. Substances which were used for masturbation are as follows.
a) Candle and candle-like substances are 26 cases (44%).
b) Thin metal manufactured goods and plants are 11 cases (18.6%).
c) Rubber tubes are 4 cases (6.6%).
d) Chopsticks and pencils are 4 cases, (6.9%).
e) Clinical thermometer and glass-rods 3 cases (5.1%).
6. 10 patients in those cases did not complain of any trouble for a long time after they had introduced foreign bodies into the bladders.
7. In 79 cases formation of calculi with foreign bodies in the urinary bladders (82.3%) were found.
8. For diagnosis of foreign body in the urinary bladder cystoscopy is necessary and enough, it is interesting to take X-ray photograph and when the foreign body is negative by X-ray, then pnenmocytography must be tried ofter washing the bladder with “Umbrathor” about 10-20c.c.
9. Non-operative therapy is best and as a candle solvent (Xyrol) is convenient.
