A radiological approach to the through and through technique for percutaneous passage of ureteric strictures.
Some ureteric strictures are so tight that they are difficult to traverse with balloon catheters or internal stents. We present five such cases, which were traversed using a modified through and through technique with a hydrophilic coated guide-wire. The reasons for the difficulty are discussed, and the merits of the modified technique compared with conventional techniques are described.
