Trocar cystostomy is a well described technique for blad­der drainage. Numerous kits are available for this purpose. A drawback of these kits is the inability to place a self­retaining balloon catheter for drainage. Moreover, these catheters have a tendency to slip out before the track ma­tures. Since most of our patients live in the interior of the state, reinsertion of a suitable catheter for bladder drainage becomes difficult. The Campbell fenestrated trocar [1] makes it possible to place a Foley catheter in the bladder. Most hospitals and primary care clinics do not possess the Campbell trocar but have a regular metal trocar and canula which is used for drainage of hydroceles and other cystic masses at surgery. We describe a technique using the exist­ing trocar and canula along with an ordinary "drinking straw" sterilised by autoclaving or chemical (glutaralde­hyde) to place a Foley catheter in the bladder for long-term drainage.


Once the trocar with the canula is introduced into the bladder [Figure 1], the trocar is removed and the straw is passed through the canula into the bladder. The canula is then removed and a 12Fr. Foley catheter is passed through the lumen of the straw into the bladder. The balloon is inflated and the straw cut away with a scissors. The same principle can be used after percutaneous nephrolithotripsy to place a Foley catheter for drainage or tamponade. In this case, the straw is passed through the Amplatz sheath and later cut away once it is ascertained that the catheter is in the collecting system.

 Comparision with Other Methods

The techinque described does not suggest that the other methods of instituting bladder drainage are inferior. It serves to add to the surgical armamentarium in situations where due to non-availability of specific instruments, techniques using available equipment need to be devised. This technique has been used in this hospital for bladder drainage for some time and more recently after percutaneous procedures.
