ABSTRACT
This study aimed to measure renal stone using different modality [kidney, ureters and bladder [K.U.B], fluoroscopy and intravenous urography [I.VU]], to compare these three methods of measurements and to detect the variation of stones size after each lithotripsy shock for the same type of stones. A total of 26 patients males [19] and females [7] their age ranged between 18 and 70 years with renal stones, I.VU, K.U.B were done for all cases. In Al Nelain Medical Centre, The size of renal stone was measured in K.U.B and I.VU by using the Ruler exposure. Staghorn stones which were >4 cm needed >4 times of exposure to. Results: The findings were found to be that stone < 1 cm can be measured but does not disintegrated by lithotripsy and most of the stones that were > 1 cm were properly measured when using the fluoroscopy and were treated effectively after 2[nd] time of the shock waves. This study concluded that the surface area, site, number of stones after extracorporeal shock wave lithotripsy [ESWL] could be detected using K.U.B, I.VU and fluoroscopy, and could help in prospective selection of patients who will respond well to ESWL
