Urethrotomy
Urethrotomy is a medical procedure used to treat urethral stricture, a condition where the urethra becomes narrowed, causing difficulty in urination. This procedure involves the surgical incision of the urethra to relieve the obstruction.
Indications[edit]
Urethrotomy is typically indicated for patients with:
- Recurrent urethral strictures
- Strictures that are not amenable to urethral dilation
- Strictures causing significant urinary symptoms or complications
Procedure[edit]
The procedure is usually performed under general anesthesia or spinal anesthesia. A specialized instrument called a urethrotome is inserted into the urethra. The urethrotome has a blade or laser at its tip, which is used to make an incision in the stricture, thereby widening the urethral passage.
Types of Urethrotomy[edit]
There are two main types of urethrotomy:
- **Cold knife urethrotomy**: Utilizes a cold knife to make the incision.
- **Laser urethrotomy**: Uses a laser to cut through the stricture.
Postoperative Care[edit]
After the procedure, a urinary catheter is usually placed to keep the urethra open and allow for healing. The catheter is typically left in place for a few days to a week. Patients are advised to drink plenty of fluids and may be prescribed antibiotics to prevent infection.
Complications[edit]
Potential complications of urethrotomy include:
- Recurrence of the stricture
- Urinary tract infection
- Bleeding
- Urinary incontinence
- Erectile dysfunction
Alternatives[edit]
Alternative treatments for urethral stricture include:
Prognosis[edit]
The success rate of urethrotomy varies, with some patients experiencing long-term relief and others requiring additional procedures. The likelihood of recurrence depends on factors such as the length and location of the stricture, as well as the patient's overall health.
