Five years experience in the management of steinstrasse post shock wave lithotripsy

Abstract EN

To identify the incidence rate of Steinstrasse post shock wave lithotripsy, to evaluate the efficacy of shock wave lithotripsy using Dorniers Doli U / 50 Lithotripter in treating the Steinstrasse and to confirm that auxiliary procedures are not always necessary prior to shock wave lithotripsy.

Between October 2001 and July 2007, 1647 patients with 2241 renal stones were treated.

63 patients who developed Steinstrasse were included in this study.

Steinstrasses were classified according to the location and the size of the fragments using Coptcoat classification.

Patients’ data including the complications, management and Steinstrasse clearance were reviewed.

Steinstrasse were detected in 63 of 2241 (2.8 %) renal stones.

Of the 63 Steinstrasse patients, 61 (96.8 %) patients were presented with no obstructive complications ; 34 patients with type I were conservatively treated and required no shock wave lithotripsy, while type II and III Steinstrasse required shock wave lithotripsy therapy.

The incidence rate of Steinstrasse post shock wave lithotripsy therapy procedure was low.

Shock wave lithotripsy therapy was an effective method treating these Steinstrasse.

This study confirms that the use of prophylactic auxiliary procedure prior to shock wave lithotripsy therapy was unnecessary in the majority of the cases.
