Patients undergoing radical cystectomy in the Netherlands are registered in an online database. From January 1st, 2012, registration in the database is obligatory. In 2010 55 hospitals entered 535 patients, for the year 2011 this was 749 patients by 54 hospitals.
This section contains information for Urologic surgeons.
There are a variety of accepted treatments for primary or secondary ureteropelvic junction (UPJ) obstruction. Although open pyeloplasty remains the gold standard, several endoscopic and laparoscopic techniques are available as alternative treatment options.
These techniques include laparoscopic transperitoneal pyeloplasty, cutting balloon retrograde endopyelotomy, antegrade endoscopic endopyelotomy, retrograde endoscopic endopyelotomy, and retrograde balloon dilatation.
Open pyeloplasty is an invasive, dismembering treatment with a mean postoperative hospital stay of 6 days. Laparoscopic and endoscopic techniques are less invasive than open pyeloplasty, but they are associated with a long learning curve for the operator and a long operation time (mean, 246 minutes).
We devised a new method for treating UPJ obstruction using a detachable inflatable stent positioned via a cystoscopic transvesicular approach. The reason for developing a new method to treat UPJ obstruction was to try to help patients using a minimally invasive, straightforward, and fast procedure.
|The balloon is inflated with pure contrast agent via the pusher and remains in situ in the ureter to keep the previous treated stricture dilated while the expanded urothelium heals.
|The Overtoom balloon in conjunction with a JJ stent. In this case first place the JJ before inflating the balloon. This option provides additional drainage space, reducing the chance of renal colics due to debris or sludge in the catheters.
For a schematic overview of the intervention
|A video sequence of an ileal conduit treatment with Overtoom Balloon Catheters is shown under this link.|
Please check the Downloads tab for expert publications and instructions for use of the Overtoom Balloon.
A study into the results of the Overtoom catheter application is conducted at the St. Antonius Hospital in Utrecht (NL).
The Overtoom balloon concerns two major types of patients. Those with:
- Ureteropelvic junction obstruction (also called UPJ obstruction. Pelvic-ureteric junction obstruction. PUJO)
and those with
- Brickers bladder (also called Ileal conduit) problems. Read more on Bricker's ileal conduit.
An intervention according to the Overtoom procedure is significantly less invasive than the alternative treaments.
The treatment with the Overtoom balloon furthermore avoids several major complications which may occur after conventional surgery. Hence the maximum of minimal organ damage. Please consult your urologist prior to intervention and ask for information.
