[Long-term effect of extracorporeal shockwave lithotripsy on kidney. A preliminary study].
We studied 139 patients with upper urinary tract calculi who were treated by JT-ESWL-I and III type extra corporeal shock wave lithotripter (ESWL) for an average of 4 years and 11 months. These patients aged below 45 had no history or family history of hypertension. Hypertension was found in 1 patient (0.7%) and elevated diastolic pressure in 6 (4.3%). The recurrence rate of calculi was 5%. Before and after ESWL, Bun, Cr, B2-mG (of blood and urine), activity of blood plasma renin AT-II, -GT, NAG, mucoprotein of plasma, etc were also determined. The differences in their values were not significant. We concluded that if the indications for ESWL are strictly considered including patient selection and number of wave pulsation and energy, ESWL is still an ideal method of treatment.
