عوارض سنگ شکنی برون اندامی (ESWL) دستگاه اد

ABSTRACT At present 80% of the stones that required surgical operation, successfully were managed by ESWL. Although this procedure is non-invasive, still it is not free of complications. The purpose of this study is to identify the possible complications and to find the ways to minimise problems. We made retrospective descriptive study of 1205 precedure cases of UT stones treated with ESWL during a 2 year period (1997 and 1998) in Razi hospital in Rasht. In each case, diagnosis of stone was made with IVP or sonography, and routine investigation and preparation were done (CBC, U.A, U.C, pregnancy test ete). ESWL was conducted in adult patients with narcotic analgesic and in children and few others with light anesthesia. ESWL apparatus used was Dorniers, MPL 9000, Maximum energy delivered was 24 KW, and in each session for renal stone 3000, in ureter and bladder stones 4000 shocks were applied. In total of 1205 cases, 1006 (83.5%) were renal calculi, 191(16%) were ureter calculi, and 8(0.5%) were bladder stones. complications noted were as follows: (A)- During procedure: 1- Pain 10%, 2- Nausea/ Vomiting 8% (B)- Early post operation:1- Macroscopic Hematuria 32% 2- Colicky pain 30% 3- UTI 807% 4- Urinary obstruction 21% In conclusion, ESWL due to its non-invasive character, as ambulatory procedure, more cost effective than open surgery and less complication, is the best treatment for the most cases of urinary stones.
