Audit of Extracorporeal Shockwave Lithotripsy in 210 Sudanese Patients at Gezera Hospital for Renal Diseases & Surgery (GHRD&S) Sudan

Abstract

Background: Extracorporeal Shock Wave Lithotripsy (ESWL) was the breakthrough
in urolithiasis management in the 20th century.
Objectives: to audit the outcome of ESWL and evaluate its cost effectiveness on the
treatment of stone disease in Gezira Hospital for Renal Disease and Surgery
(GHRD&S), Sudan
Methods: This is a prospective study of 210 patients. ESWL was performed with SLX
MX STORZ machine. The number of shocks administered, and the degree of energy
were supervised with maximum allowance of 2500-3000 shocks and 5-7 energy in
kidney and/or 3000-3500 shock 7-8 energy level for ureteral stone with modification
when it was indicated
Results: Out of 210 patients; 28, 12, 28 and 2 patients had upper, mid, lower ureteric
and vesical stones respectively. Where as 140 patients had renal stones. The success rate
of fragmentation of the stones with ESWL was 97.1% for the renal, 92 % for the upper
and lower ureter and 83.3% for mid ureteric stones. Vesical stones were not amenable for fragmentation in this study. The overall success rate was 95%. The complications were haematuria in one patient, pain and steinstrasse in two patients. There were no cases of post ESWL renal failure, hypertension and/or residual calculi.
Conclusion: This modality of treatment was found to be less costly, acceptable with short hospital stay and short work absence.
