Transurethral and suprapubic catheterization are easy and safe procedures provided that a few simple rules are followed. Primarily, a transurethral catheter is placed if there is no urethral injury or stricture. Local anaesthesia of the urethra up to the sphincter region and a well-stretched penis warrant an atraumatic insertion of the catheter into the bladder. The use of a thick catheter with a round tip or of a catheter with a bended tip under rectal guidance facilitate the insertion of the catheter in difficult conditions. Alternatively, a suprapubic catheterization can be performed provided that no contraindication such as history or suspicion of transitional cell carcinoma is present. Optimal interventional conditions using ultrasound-guidance are mandatory in patients after abdominal surgery and with hemorrhagic diathesis in view of a safe and straight-forward placement of the suprapubic catheterization. In case of persistent bleeding after insertion of a suprapubic catheter, the suprapubic catheter should be replaced by one with a balloon blocked and kept under tension for several minutes."}
