RESUMO
Objective: To compare the outcome of percutaneous nephrolithotomy [PCNL] in terms of operative time, hospital stay, stone clearance, and postoperative complications in adult versus paediatric patients
Study Design: Descriptive case series
Place and Duration of Study: Shifa International Hospital, Islamabad, from January 2010 to December 2013
Methodology: A retrospective analysis of 155 patients who underwent PCNL from January 2010 to December 2013. The patients were divided into 2 groups: patients aged ? 12 years were included in paedriatic group [A] while patients aged > 12 years were included in adult group [B]. The patients were analyzed for age, gender, stone size, operative time, stone clearance, hospital stay, and peroperative and postoperative complications. Data was collected by chart review on specified proforma
Results: One hundred and twenty-nine [129] patients including 44 [34.10%] females and 85 [65.89%] males with a mean age of 45.00 +/- 1.44 years were adults. Twenty-six palrents with mean age of 9.21 +/- 5.70 years, 17 [65.4%] males and 9 [34.6%] females, were included in the paedriatic group. Mean stone size was 2.12 +/- 1.01 cm in paedriatic group compared to 2.52 +/- 0.77 cm in adult group [p = 0.023]. Mean operative time in paedriatic group was 158.8 +/- 39.63 minutes compared to 119.34 +/- 37.06 minutes in adult group [p < 0.001]. Mean hospital stay in paedriatic group was 2.76 +/- 1.14 days compared to 3.12 +/- 1.27 days in adult group [p=0.1881]. Peroperative stone clearance was in paedriatic group was 93.28 +/- 9.23% compared to 90.81 +/- 12.23% in adult groups [p = 0.331]. One patient in the adult group developed urosepsis
Conclusion: There was no significant difference in outcome of percutaneous nephrolithotomy in terms of hospital stay, stone clearance, and postoperative complications in adult versus paediatric patients. Operative time was significantly shorter in adult cases compared to paedriatic cases
