Voiding cystourethrography in boys. Does the presence of the catheter during voiding alter the evaluation of the urethra?
Our study shows that a urethral catheter does not alter the diagnosis of abnormalities of the posterior urethra but may hamper the observation of normal structures or abnormalities of the anterior urethra.
Our study shows that both a partial and a total fundoplication are effective in controlling the symptoms of GERD in patients with defective peristalsis. Dysphagia improves significantly after total fundoplication but not after partial fundoplication. Although both operations brought acid reflux to within normal limits, the effect was more pronounced with total fundoplication. Total, but not partial, fundoplication produced a significant increase in amplitude of esophageal peristalsis, which may explain the subjective improvement during deglutition. Therefore, fundoplication should be the treatment of choice in patients with GERD and defective peristalsis.
