    Notizen: Abstract We examined 50 asymptomatic patients 6–60 months after percutaneous nephrolithotomy (PCNL) by high-resolution sonography and additional colour-coded sonography and compared our results with the preoperative sonograms and the operative records. No lesions of larger vessels were detected, either arteriovenous fistulate or pseudoaneurysms. Avascular band-shaped hyperechoic parenchymal stripes were found in 17 of 50 patients (35%). As these did not appear in the preoperative sonograms, and as the stripes were in the same orientation as the neprrostomy canal, we believe them to be scar tissue.

    Blood pressure changes after extracorporeal shock wave nephrolithotripsy: prediction by intrarenal resistive index (1996)

    Notizen: Abstract In order to identify a high-risk group for the development of arterial hypertension after extracorporeal shock wave nephrolithotripsy (ESWL), we correlated the increase in renovascular resistance induced by ESWL in 79 normotensive patients with changes in arterial blood pressure occurring 20 (+-3) months after therapy. Renal vascular resistance was measured as resistive index (RI) by duplex Doppler sonography in both kidneys. Mean RI before treatment was 0.620±0.035 (SD). After treatment, we observed a significant and age-dependent increase in the RI in the treated kidney to 0.673 ± 0.06. Of the patients with a post-ESWL RI〉 0.690, 39% developed hypertension. Posttherapy RI values surpassing 0.690 showed a 0.8 sensitivity and a 0.7 specificity in predicting arterial hypertension. Intrarenal Doppler ultrasound (US) is useful to find the high-risk group for arterial hypertension after ESWL.
