A novel insertion technique for urinary catheters in female dogs with the use of a guidewire

Abstract

Background Complicated transurethral urinary bladder catheterization in female dogs is a commonly encountered urologic problem, often causing inadvertent trauma to the lower urinary tract and breach in aseptic technique. Key Concepts A novel method for transurethral insertion of urinary catheters in female dogs is described. The main variation from current procedures involves the application of the Seldinger technique with the use of an introduction catheter that is specifically designed to feed into the urethra, and the use of a guidewire to replace the introducer with an indwelling balloon catheter. Significance The technique presented offers a step‑by‑step approach that could improve success in urinary catheter placement. This modification may facilitate catheter insertion, be less traumatic, and offer better control of asepsis, especially with challenging urethral catheterization. The technique also offers an easy method to replace the catheter. Application of the technique may reduce catheter‐associated urinary tract infections as it addresses certain infection‐related risk factors. Prospective validation studies are needed to support its advantages over current urinary catheter placement techniques.

Alternative non-oral nutrition in a rat model: a novel modified gastrostomy technique

“…After inserting a balloon catheter into the stomach, inflation of the balloon helps to prevent it from falling out from the gastric wall. In much out of the literature, most of the animal studies have reported about the use of Foley catheters as urocatheters [ 25 , 26 ]. In humans, Bendel et al reported the short-term safety and efficacy of a co-axial angioplasty balloon technique for percutaneous radiologic gastrostomy catheter placement in the human body [ 27 ].…”
