extracorporeal shock wave lithotripsy in pediatric renal stones(efficacy and safety)

In situ ESWL gives remarkably good results in children due to the friability of newly formed stones, as well as, the compliance of the urinary tract. The great majority of upper urinary tract calculi that are not spontaneously eliminated have to be fragmented by ESWL. Although, concerns about the potential long-term renal damage associated with ESWL in children have delayed the acceptance ofESWL into pediatric practice. Despite these concerns, many authors have reported their experience of using ESWL for treating urolithiasis in children Our study included 20 patients aging 2 - 14 years old with renal stones. The study was done in the Urology Department, ESWL unit, Zagazig University hospitals from November, 2004 to November, 2005. Patients included in the study had Normal kidney functions and Stone size is 0.5 to 2 ern. All the patients were subjected to: 1- Full history taking and thorough physical examination. 2- Laboratory investigations: Urine analysis, culture and sensitivity, renal function tests and coagulation profile. 3- Plain UT, Abdominal ultra-sound, IVP and Renogram. Radionuclide studies were performed within one week pre ESvVL and 3 months post ES WL. ESWL was performed using Dornier lithotripter. We used 1500 - 4000 shock waves/session and the voltage was 12 K v and was increased gradually to a maximum mean power of 15 Kv \
