postinstrumentation

— If the circumstances warrant the use of specific catheter for a patient with additional pathology such as a false passage, BPH or post-TUR and wire-guided placement is preferred, using an IV catheter (angiocath) maintains the structural integrity of the catheter facilitating precise guidance.[ 4 ] A three-way irrigation catheter may be advanced over a wire in cases such as hemorrhagic cystitis, hemorrhagic prostatic urethra, and postinstrumentation.
