To compare the rate of stone free after one week in
patients of renal stones (1-2 cm) by PCNL
(Percutaneous Nephrolithotomy) versus ESWL
(extracorporeal shock wave lithotripsy)
This Randomized Controlled Trial was conducted
at Urology Department, Galway University Hospital,
Galway, Republic of Ireland from 1
st January 2018 to
31st December 2018. Total 104 patients were included.
The patients were divided into two groups. Group-A (52
cases) with ESWL, while Group-B (52 cases) with
PCNL. The patients were briefed about both the
techniques, their likely consequences in terms of
advantages and disadvantages. The procedure was
considered successful if the patient will be stone free.
Data were entered and analyzed in statistical software
Statistical Package for Social Sciences (SPSS) v25.0.
Data were stratified for age, gender and socio-economic
status to address the effect modifiers. A p-value ≤0.05
was considered as a level of significance.
One hundred and four patients fulfilling the
inclusion criteria were included in this study. Patients
were divided in two groups i.e. Group-A (ESWL) and
Group-B (PCNL). The mean age of patients in group-A
was 43.5±12.5 years and in group-B was 45.8±15.3
years. In group-A, stone free rate was 39(75.0%), while
48(92.3%) in group-B with a p-value of 0.017, which is
There is a difference of stone free rate at one week
after extracorporeal shock wave lithotripsy (ESWL)
versus Percutaneous Nephrolithotomy (PCNL) for renal
stones of 1-2 cm.
