Ask Dr. Z

At the risk of sounding stupid, I just have to ask because I'm still not grasping the difference between the twp separate sets of stent codes when they are not clearly spelled out in the report (that I can tell). How do you know which this is, 50695 or 50433? My guess is 50433? "A 5 French coaxial introducer was placed the dilated left renal pelvis using micropuncture technique. A nephrostogam was done. Antegrade ureteral stent placement: A 0.035 wire successfully advance into the bladder . A 5 French Angiocath then was advanced over the guide wire in the bladder. The glidewire was exchanged with super stiff guidewire. The needle tract was dilated to 9 French . A 6 French x 22 cm was inserted over stiff guidewire under fluoro into the bladder. The guide was pulled back out of the upper end of the stent but was kept in the renal pelvis. An 8.5 French nephrostomy catheter inserted into the renal pelvis and the stiff guide wire removed. The nephrostomy catheter was secured on the skin with adhesive tape. The final image showed a good position of the stent and nephrostomy catheter."
