The role of ESWL in the treatment of calculi with anomalous kidneys

WOS: A1997WU39500008PubMed ID: 9129920Objective: To evaluate the efficacy of Extracorporeal shock wave lithotripsy (ESWL) in renal anomalies. Material and Methods: From 1991 to May 1995, 53 patients with calculi in anomalous kidneys presented to our clinic for treatment with ESWL. Average patient age was 39 years, a range of 6-66 years. These patients (32 male and 21 female) underwent ESWL treatments. ESWL was performed in 27 patients with urolithiasis in duplex system, 18 with horse-shoe kidneys, 4 with unilateral renal agenesis, 2 with pelvic ectopic kidneys, 1 with sigmoid kidney and 1 with L-shaped kidney. Results: Among patients who completed ESWL the rate free of stones was 60.4% and the rate of clinically insignificant residual fragments was 30.2%. No sign of stone disintegration was observed in 2 patients. They underwent open surgery. The shock waves per therapy varied between 811 and 18,101. Double-J stents were placed in 13 patients. Conclusion: Most patients with calculi in anomalous kidneys can be managed primarily with ESWL
