Despite reviewing 39 eligible trials, few firm conclusions could be reached because of the multiple comparisons considered, the small size of individual trials, and their low quality. Whether or not to use a particular policy is usually a trade-off between the risks of morbidity (especially infection) and risks of recatheterisation.
Optical internal urethrotomy with and without catheter. A comparative study.
The role of postoperative catheter treatment after optical internal urethrotomy was studied in a prospective, consecutive, randomised series of 54 patients. Group one was treated without catheter and group two with catheter for one day. No significant difference in recurrence rate was found between the two groups studied by means of voiding interview, uroflowmetry and retrograde urethrography.
