Stone clearance and fragmentation after ESWL in operated and non operated patients

ABSTRACT

A comparative study was conducted in 78 renal stone patients to evaluate the efficacy of ESWL in operated and non operated cases. The operated group consisted of 38 patients whereas non operated group comprised of 40 patients. After ESWL stone fragmentation was 80%, 90% and 96% in the operated group at one, two and three months respectively. In the non operated group stone fragmentation was 86% at one month and 100% at two and three months. In the operated group stone clearance was 8%, 18%,49% at one, two and three months. In the non operated group stone clearance was 7% at one month, 38% at two months and 53% at three months after ESWL. No significant difference in stone fragmentation between the operated and non operated group was found up to three months. The stone clearance was also similar at one month but was significantly lower at two months and again similar at three months in the operated group as compared to the non operated group
