Abstract:
OBJECTIVE: To compare the outcome of Extracorporeal Shock Wave lithotripsy and litholapaxy in treating vesicle calculi. PATIENTS AND METHODS: The study included total of 100 patients divided into two equal groups of Extra corporeal shock wave lithotripsy (ESWL) and litholapaxy (LL). Study was conducted between December 2007 and November 2008.ESWL was done under analgesia only while Litholapaxy was done under general anasthesia after a single dose of pre-operative antibiotic. Chienese Lithotripter of spark gap technology was used to impact shock waves. 3500 shock wave were given in one session. Lithotripter (storz) was used for ESWL in all cases. Post ESWL and postoperatively patients underwent radiography and th ultrasonography as required at 4 day of follow up to asses stone clearance. RESULTS: The mean patient age in ESWL and LL group was 38 ±10 and 40± 10 years respectively. The male to female ratio and stone size were similar between the groups. In ESWL group 2% patients got fever,4% had LUTS, and 4% patients visited the emergency room (ER) with in 24 hours of session. In this group 36 patients visited ER, required Auxiliary procedures. While in LL group 6% patients developed fever,8% had LUTS, 6% patients visited the ER..34 patients were cleared in single procedure, 4 required repeat procedure and 10 presented with small retained particles, which ultimately required ESWL. Stone free rate after a single procedure was 76% in ESWL and 72% in LL group. Complication rate was 10% in ESWL group whereas it was 20% in LL group. ESWL is 25% cheaper than LL. CONCLUSIONS: ESWL is a better modality as compared to Litholapaxy for treating vesicle stones of 2cm or less in terms of efficacy, complications, stones clearance and cost effectiveness.
