The results of percutaneous pyelolysis in 28 patients are presented. There were 18 successful and 10 unsuccessful cases. The indications for the procedure are defined in the light of this analysis.
One hundred and sixteen patients with detrusor instability, detrusor hyper-reflexia or bladder hypersensitivity who had failed to respond to standard conservative methods of management were treated by transvesical infiltration of the pelvic plexuses with phenol. A satisfactory response was obtained in detrusor hyper-reflexia (82%), in detrusor instability in patients over 55 years of age (69%) and in idiopathic bladder hypersensitivity (68%). The response rate was much less satisfactory in detrusor instability in patients less than 55 years of age (14%) and when there was a definable cause for bladder hypersensitivity (0%).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
