Insights
Intravesical detrusorrhaphy, a modified ureteral reimplantation, effectively treats vesicoureteral reflux (VUR) and obstructive megaureter (OM). This technique shows high success rates and avoids postoperative urinary retention in bilateral cases.
Area of Science:
- Pediatric Urology
- Surgical Techniques
- Urology
Background:
- Vesicoureteral reflux (VUR) and obstructive megaureter (OM) are common pediatric urological conditions.
- Traditional ureteral reimplantation techniques can have associated complications.
Purpose of the Study:
- To describe the surgical procedure of intravesical detrusorrhaphy.
- To report initial clinical experience with this modified ureteral reimplantation technique.
Main Methods:
- An open intravesical approach was used for intravesical detrusorrhaphy.
- The technique involves creating a submucosal tunnel by repairing the detrusor underneath the mobilized ureter.
- The ureteral orifice is anastomosed to its orthotopic position.
Main Results:
- The study included 55 children with VUR and 13 with OM.
- Success rates for VUR resolution were 91.1% (68/72 ureters).
- Improvement rates for OM were 84.6% (11/13 patients, 12/14 ureters).
- No postoperative urinary retention occurred in bilateral cases.
Conclusions:
- Intravesical detrusorrhaphy is a safe and effective modified ureteral reimplantation technique.
- It successfully recreates the neo-ureteric orifice in the orthotopic position.
- The procedure is well-tolerated, with no reported urinary retention in bilateral procedures.
Purpose:
To describe the surgical procedure of intravesical detrusorrhaphy, a modified technique of ureteral reimplantation, and report our initial experience.
Methods:
From October 2007 to March 2012, 55 children with vesicoureteral reflux (VUR) and 13 children with obstructive megaureter (OM) underwent intravesical detrusorrhaphy. All surgical procedures were performed via an open intravesical approach. The ureter was mobilized, and the bladder mucosa was separated from the detrusor in a cephalad direction. The separated detrusor was incised vertically and repaired underneath the mobilized ureter to create the submucosal tunnel. The ureteral orifice was anastomosed to its orthotopic position.
Results:
Of 31 patients treated with bilateral intravesical detrusorrhaphy, no patient had postoperative urinary retention. Follow-up voiding cystourethrography was performed in 45 patients with 72 reimplanted ureters. VUR was resolved in 41 patients (91.1%) with 68 ureters (94.4%). Among 13 patients with 14 ureters treated for OM, hydroureteronephorosis improved in 11 patients (84.6%) with 12 ureters (85.7%).
Conclusions:
Intravesical detrusorrhaphy is modified technique of ureteral reimplantation, which recreates the neo-ureteric orifice in the orthotopic position and does not produce postoperative urinary retention in bilateral cases. Intravesical detrusorrhaphy is safe and effective in treating patients with VUR or OM.
