Efficacy of micro pcnl for renal stones in pediatric age group

Abstract

Background: Renal calculi is mineral deposit in the renal calyces and pelvis that are found free or attached to the renal papillae. Management of kidney stone disease in pediatric population is a challenging condition in urology practice. While the incidence of kidney stone is increasing in those group, technological innovations have contributed to the development of minimally invasive treatment of urinary stone disease such as mini-percutaneous nephrolithotomy (mini-PCNL), micro-PCNL, ultra mini-PCNL. Aim: To find the frequency of stone clearance and post op hematoma after micro PCNL in pediatric patients with renal stones. Place and duration of study: Department of Urology, Shaikh Zayed Hospital, Lahore from 25-01-2020 to 25-07-2020. Methodology: After approval from the hospital ethical committee, 60 all the children of 18 years presenting in Department of Urology fulfilling the inclusion criteria were included. An informed consent was obtained from patients. Before performing micro PCNL renal stone was confirmed on CT-Scan KUB plain. After proper selection of the patients, they were prepared for surgery. After preparation patients were put on list for micro-PCNL. Surgery was performed. Post operatively CT-Scan KUB plain was performed to see the stone clearance four weeks after surgery. Post hematoma was noted according to Clavien Grading Scoring. Results: Out of 60 patients, 19(31.7%) were in group ≤10 years of age whereas 41(68.3%) in were in group 11-18 years of age, mean age was calculated as 12.90±3.16 years. There were 44(73.3%) were male whereas 16(26.7%) were females. Frequency of stone clearance was 56(93.33%) and post op hematuria was 4(6.66%) after micro PCNL in pediatric patients with renal stones. Conclusion: We found that, after Micro PCNL in pediatric patients with renal stones there were good stone clearance rate and less hematuria. So micro PCNL is good technique for stone clearance and less complications occurred. Keywords: Urinary tract stone, PCNL, Renal Calculi.
