True about Latzko technique of genitourinary fistula repair is
**Core Concept**
The Latzko technique is a surgical approach used to repair genitourinary fistulas, specifically those between the bladder and vagina. This technique involves the use of a pedicle flap to separate the fistula tract from the surrounding tissues, promoting healing and closure.
**Why the Correct Answer is Right**
The Latzko technique is a well-established method for repairing genitourinary fistulas, particularly those that have failed to heal with conservative management. The technique involves creating a pedicle flap from the vaginal wall, which is then used to cover the fistula tract. This flap provides a blood supply to the area, promoting granulation tissue formation and eventually leading to fistula closure. The Latzko technique is often preferred over other methods due to its high success rate and minimal morbidity.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because the Latzko technique is not typically used for fistulas between the ureter and bladder.
* **Option B:** This option is incorrect because the Latzko technique does not involve the use of a mesh or graft to repair the fistula.
* **Option C:** This option is incorrect because the Latzko technique is not a conservative management approach, but rather a surgical intervention.
**Clinical Pearl / High-Yield Fact**
The Latzko technique is a valuable tool in the management of genitourinary fistulas, particularly when conservative measures have failed. It is essential for urogynecologists and general surgeons to be familiar with this technique to provide optimal care for patients with fistulae.
**Correct Answer: C. Latzko technique involves creating a pedicle flap from the vaginal wall to cover the fistula tract.**
