Key words : Extracorporeal Shock Wave Lithotripsy, urolithiasis patients,
Songklanagarind Hospital
Objective : To determine 1) number and details of urolithiasis patients such as stone site, age, gender, method of payment, financial support by Social Welfare Section and by Songklanagarind Hospital Foundation, and 2) Extracorporeal Shock Wave Lithotripsy (ESWL) in comparison with
open surgery and ureterorenoscopy (URS).
Methods : A retrospective study was conducted in urolithiasis patients who had undergone
open surgery or URS in Songklanagarind Hospital between January 1993 and December 1999, and patients who had undergone ESWL between January 1996 and December 1999. The data collected were age, gender, domicile, stone sites, and the payment status for ESWL service. The use of Extra-corporeal Shock Wave Lithotripsy was studied by comparing the number of patients before and after
the availability of ESWL, together with comparing the service fees of ESWL, open surgery and URS.
Results : In the study period there were 4,166 patients; 33.9 percent were new patients. Sixty
one percent of this group were males and 39 percent were females. Renal calculi were most common (80.5%). Most of the patients (26%) were in the age range of 40 to 50 years old. Half of the patients had their expenses reimbursed from the government. 25.4% were from Songkhla province. After the availability of ESWL, it was observed that the number of patients increased by 89%, and the number
of patients undergoing open surgery decreased by 15.5% while the number of patients undergoing
URS increased by 260.5%. The fee for the first to the fifth ESWL visit was 20,000 Baht and 5,000
Baht for each ESWLvisit from the sixth visit on. The average fee for open surgery for a patient stay-ing in an ordinary room was 8,924 Baht, and 21,180 Baht for a private room, whereas the fee for URS for a patient staying in an ordinary room was approximately 9,500 Baht.
Conclusion : In the study period, Songklanagarind Hospital rendered its ESWL service to patients in the 14 southern provinces. ESWL reduced the number of open surgeries and incurred approximately the same service fees.
