The value of 64 slice spiral CT urography in the diagnosis of urinary system congenital malformation

Objective To investigate the value of 64 slice spiral CT urography( CTU) in the diagnosis of urinary system congenital malformation. Methods Thirty-four patients who had urinary system congenital malformation which were confirmed by cystoscope and operation were examined with CTU,combined with the staging scan,the statistical analysis of the urinary system malformations were completed. Results Of the 34 patients,renal agenesis was found in 2 cases,renal dysplasia in 6 cases,renal fusion malformation( horseshoe kidney) in 4 cases; duplication of renal pelvis and ureter in 7 cases,congenital ureteral stenosis in 8 cases,abnormal ureteral orifice in 4 cases; bladder diverticulum in 2 cases; congenital bladder fistula of rectum in 1 cases; compared with the results of operation,the diagnosis rate was 100%. Conclusion CTU for the diagnosis and classification of urinary system congenital malformation is of great clinical significance,and provides a guidance for clinical operation.
