title: A radiological approach to the through and through technique for percutaneous passage of ureteric strictures.
abstract: 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.
