Abstract
Dynamics of the bladder and urethra were studied utilizing rentogenological methods in resistant and/or recurrent urinary tract infection in female patients combined with some clinical studies. Those patients could be divided into two group 1) deformed bladder and/or urethra group: 2) non-deformed group. In non-deformed group the bladder made a funnel shape pointing the head to the urethra and contracted itself co-ordinately on urination. In deformed group the bladder contracted uneqally forming a linear solid line in the bottom of the bladder following residual urine. Those changes were found in 11 patients out of 24 and 8 of which were received gynecological operations. The fact strongly suggested a relationship between the urinary tract infections and deformities in those organs due to gynecological operations. The deformed group showed strong resistance against many kinds of chemotherapies. In strong resistant and/or recurrent pyelonephritis cases, considerable degree of renal ptosis were observed in 25%, nephropexy was seemed to be useful operative procedures in those patients.
