title: Detection of source of haematuria after extracorporeal shock wave lithotripsy (ESWL) by automated measurement of urinary red cell volume.
abstract: Midstream urine samples taken from 35 patients with secondary haematuria due to nephrolithiasis and 31 patients with haematuria after ESWL were compared using a red cell analyser (RCA) to differentiate the source of haematuria. Urine samples obtained from both groups were examined by RCA for urinary red cell mean corpuscular volume (UMCV) and urinary red cell volume distribution curves (RCVDC). To rule out the influence of blood MCV (BMCV), BMCVs were determined separately and the ratio of UMCV/BMCV (R) was calculated. Although our findings showed no difference between haematurias after ESWL and nephrolithiasis, we cannot exclude a direct effect of shock waves on renal tissue.
