Long-term follow-up after extracorporeal shock wave lithotripsy of large kidney stones.
In 76 patients (53 women and 23 men) aged 24-92 years, extracorporeal shock wave lithotripsy (ESWL) was performed between June 1986 and December 1988 as monotherapy for large kidney stones (diameter > 2.5 cm). There were 41 complete and 24 partial staghorn calculi. The patients were treated with the Dornier HM3 lithotripter under sedoanalgesia. Of the 60 patients with large stones whose last ESWL treatment had been at least 24 months earlier, only 15 ultimately came for this long-term control check-up. Reports on 15 other patients were received from their doctors stating that the patients were doing well, not having new stone episodes. These subjects had to be excluded from final evaluation since they did not fulfill all requirements. Thirty patients had either moved out of the area or were from distant locations and therefore unable to appear. Creatinine was normal and urinalyses negative in these 15 patients; 12/15 were stone-free. The ones who were not had small remnants in the lower pole calices which did no harm at all. One patient already had elevated pretreatment blood pressure; 6/14 with normal blood pressure before ESWL showed elevated values 30 or more months after the last ESWL. Radioisotope examinations with separate clearance tests demonstrated no real evidence of loss of kidney function on the treated in comparison with the untreated side. Sonographic findings on the longitudinal and transverse diameter of the treated and untreated kidneys with regard to the total number of shock waves did not show marked differences as they all remained below the 9% limit.
