For one day the perioperative antibiotic medications are ciprofloxacin 500 mg p.o. 1-0-1. The antibiotic prophylaxis can help the patient to deal with the urinary tract infection. Additionally, this can help to reduce the recurrent urinary tract infection, fever, and urethral strictures.

Preoperative Preparations

The patient needs to stay in a lithotomy position. Disinfect the lower abdomen, sterile draping, perineum, and external genitalia. General anesthesia or spinal anesthesia is given for internal urethrotomy.

Direct-Vision Internal Urethrotomy

Direct-vision urethrotomy is the transurethral incision of the stricture. A cold knife is used and an alternative option to cut the structure is with a laser fiber. To minimize scar contraction, it is important to reach healthy tissues.

Postoperative Management after Internal Urethrotomy

  • Control micturition with the urinary flow and residual urine
  • Perioperative antibiotic treatment
  • A transurethral catheter for 2 to 7 days, depending on urethrotomy length. Long-term catheterization for up to 6 weeks. Recurrent urethral obturation helps in stopping recurrent urethral stricture

Complications of Internal Urethrotomy
