Ten of 42 patients with cystinuria admitted for extracorporeal shock wave lithotripsy (ESWL) treatment had ureterolithiasis. Of these, 3 had bilateral stones, 2 had only 1 functioning kidney, and 2 had stones in both the kidney and ureter on the same side. Only 1 patient was on medical treatment at the time of referral. After initiation of medical treatment for cystinuria, 2 patients were discharged without further intervention, 1 was discharged after placement of a ureteric stent and 10 were treated with ESWL. After an average of 1.5 ESWL treatment sessions per ureter, 8 patients became stone-free and in the remaining 2, ureteroscopy was required to complete the treatment. Problems associated with the ESWL treatment of cystine stones are discussed. It was concluded that ESWL is the treatment of choice for ureterolithiasis in patients with cystinuria because it is effective and is the least invasive procedure even in patients with cystinuria.
