Balloon dilation, ureteral stricture, including imaging guidance (eg, ultrasound and/or fluoroscopy) and all associated radiological supervision and interpretation (List separately in addition to code for primary procedure)

Balloon dilation of a ureteral stricture is a minimally invasive procedure aimed at widening narrowed segments of the ureter, which can obstruct the flow of urine. The ureter is a tube that carries urine from the kidneys to the bladder, and strictures can occur due to various factors, including tumors or fibrosis, leading to significant complications if left untreated. The procedure can be performed using two primary approaches: through a percutaneously placed catheter or via the bladder using a ureteroscope. In both methods, radiologic guidance, such as ultrasound or fluoroscopy, is essential to accurately position the balloon over the stricture, ensuring effective dilation. During the procedure, if a percutaneous approach is utilized, a trocar or Chiba needle is inserted under imaging guidance to access the renal pelvis, allowing for urine aspiration to confirm the correct location and relieve any pressure in the urinary system. A guidewire is then threaded to the stricture, followed by the placement of a balloon catheter over the guidewire. The balloon is inflated to dilate the stricture, and a stent may be placed afterward to maintain ureteral patency. If the ureteroscope approach is chosen, the balloon catheter is directly introduced through the cystoscope, and similar steps are followed to ensure the stricture is adequately treated. The procedure is comprehensive, including all necessary imaging guidance and radiological supervision, which are integral to the successful outcome of the balloon dilation of a ureteral stricture.
