Ointment Fistulography: Introducing a Novel Technique for Single or Multiple Urethrocutaneous Fistula Diagnosis After Hypospadias Surgery

Abstract

This technique shows even tiny and multiple fistulas not detectable on physical examinations. We have used this technique in our clinic and have not missed any fistulas. The diameter of the protruded ointment in reverse fistulography is an indicator of the distal urethral diameter. Therefore, in case of narrow ointment diameter, distal urethral strictures should be suspected as correction of distal obstruction is an important determinant in the success rate of fistula repair surgery. CONCLUSION: We suggest this diagnostic technique as a safe, inexpensive, easy, office-based, feasible, and reproducible method. Negative urine culture is not required for this examination. Also, there is no need to insert contrast media as in retrograde urethrography or induce anesthesia as in cystoscopy. We believe this simple technique help urologists around the world to diagnose this common complication of hypospadias surgery without the need for special equipment.
