Patient's question:
One month ago, sudden pain in the periumbilical and waist areas was diagnosed as kidney stones.Doctor's answer:
Kidney stones, three extracorporeal shock wave lithotripsy (ESWL) procedures performed, still not passed. Consider the following possibilities:1. The stone is large in size, or the stone composition is not sensitive to ESWL, resulting in poor treatment efficacy.
2. The stone has been retained for an extended period, surrounded by inflammatory granulation tissue, making it difficult to pass even after fragmentation.
Advice:
1. No ultrasound data provided; the specific condition is unclear.
2. Since the stone was not passed after three ESWL procedures, further ESWL is no longer recommended. If the stone is located above L4 with hydronephrosis, percutaneous nephrolithotomy (PCNL) is recommended. For stones in the lower ureter, ureteroscopic lithotripsy is advised.
3. Hydronephrosis poses a risk; long-term retention can lead to thinning of the renal cortex and impaired renal function. Active treatment is necessary.
