Cystourethrography voiding

Posterior urethral stenoses can be studied with voiding cystourethrography and voiding cystoure-throsonography and may be divided into vesical neck obstructive syndrome and post-prostatectomy stenosis.

Stenoses due to pelvic fracturing, on the other hand, affect almost exclusively the membranous urethra. They can be easily investigated with retrograde urethrography and voiding cystourethrography, but are difficult to explore with sonourethrography. 

Fistulae developing in the posterior urethra are better detected using voiding cystourethrography. CT is used for monitoring and identifying the extent of the periurethral and periprostatic fluid collections.

After voiding cystourethrography (VCU), iodin-ated contrast medium is aspirated, and the bladder is slowly drained by the catheter. Electrocoagulation of the valves is performed during the following hours. Because the bladder catheter cannot be left inside the bladder for an extended period, and because there is severe alteration of the bladder contractility, renal diversion is frequently required during the first few months of life (bilateral neph-...

It is accepted that evaluation of the child with wetting with a history of infection is indicated because some 30%-50% of children who present with UTI will have VUR demonstrated on voiding cystourethrography (VCU). However, no clear guidelines have been established for the evaluation of wetting children with sterile urine demonstrated at the time of admission or without a history of UTI. In a study on children with enuresis, Sujka et al. (1991) demonstrated that no one symptom or combination of symptoms segregated these patients likely to have VUR 16% of their 83 patients with sterile urine and no history of infection had VUR out of those, 16 showed reflux nephropathy as well. They concluded that one of six children who present with enuresis and sterile urine will have VUR.
