These situations include patients with a very large median lobe of the prostate, a transplanted kidney, a cross-trigonal ureteral reimplantation, tumors/ stones obstructing the lumen of the ureteral orifice, and a distal ureteral stricture. We will present a technique that makes ureteral catheterization efficient and easier to perform. METHODS Use a 5 Fr. Open-ended ureteral catheter and an angled tip glidewire (hydrophilic guidewire with an angled tip). Insert the open-ended catheter into the scope and insert the glidewire sticking out of the inserted end. We can adjust the length, and thus curvature, of the glidewire sticking out of the inserted end. Use the Kelly clamp or mosquito clamp at the distal end of the catheter to fix the catheter to the glidewire inside. In order to steer the angled tip inside the bladder, we just need to gently rotate the clamp from the outside. The angled tip glidewire inside the bladder is soft and flexible. It can get into a challenging ureteral orifice easier than a regular open-ended catheter. We then advance both the catheter and the glidewire up the ureter. The catheter is fixed to the glidewire by the clamp. RESULTS We have used this technique to catheterize multiple patients with a transplanted kidney, cross-trigonal ureteral implantation, and with very large prostates. Once the catheter gets inside the ureteral orifice and into the ureter, we can easily release the clamp to advance the glidewire® quickly. CONCLUSIONS This technique is simple and more effective than traditional techniques – for example, using an Alberran deflecting bridge or an angled tip angiographic catheter. The Alberran deflecting bridge may also catch organs such as the prostate and cause bleeding. On the other hand, the angled tip angiographic catheter, although also curved, is static – meaning the surgeon has no flexibility in adjusting the curvature of the catheter. The advantage of using a glidewire® as opposed to simply using an open-ended catheter is that the curvature can easily be manipulated and that the wire is flexible enough to fit into tortuous paths such as a J-hook ureter. © 2016FiguresReferencesRelatedDetails Volume 195Issue 4SApril 2016Page: e774 Advertisement Copyright & Permissions© 2016MetricsAuthor Information Cu Phan More articles by this author Stephanie Y.
