While assessing a client following lithotripsy with stent insertion, which data indicates to the nurse that the procedure was successful?

A. This directly indicates that the lithotripsy procedure was successful in breaking down the stone into smaller fragments that can be passed through the urinary tract. B. While the absence of these symptoms is a positive sign, it does not directly confirm the success of the lithotripsy procedure. These symptoms can be present even if the stone has been broken down. C. Pale pink urine is expected after lithotripsy due to minor bleeding. The absence of blood clots is also a good sign, but it doesn't definitively confirm the procedure's success. D. Serum creatinine and blood urea nitrogen (BUN) levels are within normal limits. These lab values are important indicators of kidney function but do not directly relate to the success of the lithotripsy procedure itself.
