sative factor in appendicitis is suggested. 
URETERAL OBSTRUCTION 
By Dr. Jose Eduque 
Several cases of ureteral obstruction were reported. The 
diagnosis was made by Roentgen-ray photographs. Recoveries 
followed operation. The occurrence of this condition is com- 
moner than may be supposed, and is characterized by acute 
attacks of pain which may be relieved when the patient is kept 
in bed for a few hours. Skiagrams illustrating the cases were 
exhibited by Dr. Ricardo Fernandez.
