In simple words: The doctor examines your bladder and the tube that carries urine from your kidney to your bladder using a small camera. If there's a blockage where the kidney and tube connect, they'll use tools like a tiny balloon, laser, or electric current to open it up.

This code represents a procedure where a cystourethroscopy is performed, followed by the insertion of a ureteroscope up to the ureteropelvic junction (UPJ). At the UPJ, the physician treats a stricture using methods such as balloon dilation, laser, electrocautery, or incision.

Example 1: A patient presents with flank pain and hydronephrosis. Imaging reveals a UPJ obstruction. The physician performs a cystourethroscopy with ureteroscopy and balloon dilation of the UPJ stricture., A patient with recurrent UTIs is found to have a UPJ stricture. The physician performs a cystourethroscopy with ureteroscopy and laser incision of the stricture., A child with a congenital UPJ obstruction undergoes cystourethroscopy with ureteroscopy and electrocautery of the stricture to improve urine flow.

Documentation should include details of the cystourethroscopy and ureteroscopy, the method used to treat the UPJ stricture (e.g., balloon dilation, laser), the location and size of the stricture, and any complications encountered.
