Extracorporeal shock wave lithotripsy for bilateral renal stones: A case report with serious complications that could be avoided

Abstract

22-year-old male patient with irrelevant medical history presented with bilateral renal stones; multiple stones in right renal pelvis measured 10, 11, and 11mm and another one on the left side measured 12mm. Extra corporeal shock wave lithotripsy (ESWL) was done first on the left side, but after 400 shocks and total energy of 20 Storez Medical Lithotripsy Index only, the stone wasn't visible. Then, the operator switched to the right side and a he completed the session. A day after, the patient presented with bilateral renal colic, gradual rising of renal function and imaging showed bilateral steinstrasse with bilateral hydroureteronephrosis. Patient was managed with insertion of bilateral ureteric stents and had another session of ESWL on the right side. We concluded that bilateral simultaneous ESWL for bilateral renal stones doesn't affect the renal function on the long-term outcome, but still carries the risk of bilateral obstruction and acute renal injury.
