6) The physician made an incision in the left ureter through the abdominal wall for examination of the ureter and insertion of a catheter for drainage.

7) The physician examined the patient's right and left renal and ureteral structures with an endoscope, which passed through an established opening between the skin and the ureter (ureterostomy). He also inserted a catheter into the ureter.

8) The physician revised a surgical opening between the skin and the right ureter.

9) The physician injected contrast agent through an opening between the skin and the left ureter (ureterostomy) for ureterography (study of renal collecting system).

10) The physician made an incision in the left ureter (ureterotomy) to insert a catheter (stent) into the ureter.

11) The physician performed a transurethral resection of a postoperative bladder neck contracture using a resectoscope.

12) The physician inserted a special instrument through the cystourethroscope to fragment a calculus in the ureter using electrohydraulics.
