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

Rationale: A. Urine is pale pink with no observable blood clots: Light hematuria may occur after lithotripsy, but absence of clots alone does not confirm that the stones were effectively fragmented or removed. B. Stone fragments are collected when straining the client's urine: The presence of stone fragments indicates that the lithotripsy successfully broke up the calculi, allowing them to pass or be collected. This directly demonstrates procedural effectiveness. C. Client denies urinary frequency, urgency, or dysuria: Relief of urinary symptoms may occur gradually and does not immediately confirm that the stones were effectively fragmented or removed. D. Serum creatinine and blood urea nitrogen (BUN) levels are within normal limits: Normal renal function is important, but it does not specifically indicate that the lithotripsy procedure successfully fragmented the stones.
