Please help with following procedure.
2. Bilateral ureteral catheterization for ureteral urine cytology, right and left.
3. Bilateral retrograde pyelography.
DESCRIPTION OF PROCEDURE:
After the induction of general endotracheal anesthesia, the patient was placed in a lithotomy position, where she was prepped and draped in a sterile fashion. The C-arm was employed. Cystoscopy revealed no
intravesical pathology. The patient was given Lasix. A whistle-tip catheter was passed into the right ureteral orifice and a hydronephrotic drip produced approximately 10 mL of urine. This was sent for right ureteral cytology. The whistle-tip catheter was then flushed and passed into the left ureteral orifice. The hydronephrotic drip produced another 5 to 10 mL of urine, which was sent for urinary cytology. A cone-tip catheter was then passed into the right ureteral orifice and contrast injected in a retrograde fashion. This revealed no filling defect. A similar procedure was performed on the left side and again there was no significant filling defect. These normal bilateral retrograde pyelography studies prove that the minimal abnormality on CT scan was a variant of normal. The bladder was drained. All instruments were removed from the patient. The patient was aroused from anesthesia, extubated, placed on a gurney supine and taken to the recovery room in stable condition.
