In simple words: The doctor uses a thin, flexible tube with a camera (cystoscope) to examine the bladder and urethra. If a narrowing (stricture) is found in the kidney's drainage tubes, the doctor uses tools to widen it.

Cystourethroscopy involves the inspection of the bladder, urethra, prostatic urethra, and ureteric openings using a cystoscope.The procedure includes inserting the catheter tip into and through the ureter up to the intrarenal structures to treat an intrarenal stricture using methods such as balloon dilation, laser, electrocautery, or incision.The scope and instruments are removed after the procedure, and the bladder is drained.

Example 1: A patient presents with symptoms of hydronephrosis and a history of recurrent urinary tract infections. Cystourethroscopy reveals a stricture in the left ureter, which is treated with balloon dilation., A patient undergoes a nephrostomy tube placement, and during follow-up, a stricture is identified during cystourethroscopy and treated with laser ablation., A patient with a known history of ureteral stricture from previous surgery undergoes a cystourethroscopy, and the stricture is managed with electrocautery.

* Preoperative diagnosis and indication for the procedure.* Detailed operative report describing the findings and techniques used, including the type of stricture and method of treatment.* Anesthesia record.* Pathology report (if any tissue was removed).* Postoperative management and follow-up plan.
