CPT® Code 52334

CPT® Code 52334 refers to a specific medical procedure known as cystourethroscopy with the insertion of a ureteral guide wire to establish a percutaneous nephrostomy through a retrograde approach. This procedure is performed to create a nephrostomy, which is a surgical opening that allows for drainage of urine directly from the kidney. The process begins with the cleansing of the urethra using an antiseptic solution to minimize the risk of infection. A cystoscope, which can be either rigid or flexible, is then inserted through the urethra into the bladder. To enhance visualization of the bladder wall, sterile saline may be introduced into the bladder. After inspecting the bladder, the next step involves catheterizing the ureter, which is the duct that carries urine from the kidney to the bladder. A guidewire is then introduced through the cystoscope and carefully advanced into the ureter, reaching the renal pelvis or the desired calyx of the kidney. Following this, a nephrostomy catheter is advanced over the guidewire into the renal pelvis and positioned in the appropriate calyx. Once the guidewire is removed, leaving the nephrostomy catheter in place, a sheathed needle is advanced through the catheter and into the calyx until it exits the skin. The nephrostomy tract is then dilated over the needle to accommodate the nephrostomy tube, which is subsequently placed and secured with sutures. Finally, all surgical instruments, including the needle and cystoscope, are removed, completing the procedure.
