Safety and Efficacy of Percutaneous Nephrolithotomy in The Treatment of Renal Stones in Children

Abstract

Abstract Background the incidence of urinary stone disease has been increased due to the change in dietary habits, lifestyle factors and obesity. The prevalence of urinary stone disease was reported as 11.1% in the adult population, while the prevalence in children varies with age, it is approximately 2-3%. Open surgery was the only surgical treatment option in the past, now most pediatric urinary stones can be treated effectively by other procedures as extracorporial shock wave lithotripsy (ESWL), percutaneous nephrolithotomy (PCNL), retrograde intrarenal surgery (RIRS) and laparoscopy. Aim of the Study to assess the safety and efficacy of percutaneous nephrolithotomy in the treatment of renal stones more than 15 mm in children aged 2-14 years old. Patients and Methods our study included 40 patients (28 males and 12 females) with a mean age (8.35 ± 3.69) with a range (2 to 14 years) managed by PCNL in 2 groups: Group A (Preschool age group): included 18 patients, 12 males (67%) and 6 females (33%) aged (2-6 years) managed by mini PCNL.Group B (School age group): included 22 patients, 16 male (73%) and 6 females (27%) aged (7-14 years) managed by standard PCNL. Results Success rate was nearly similar in both groups, it was 88.9% in group A and 95.5% in group B. Regarding the mean operative time it was 72.22 ± 12.63 in group A and 70.00 ± 15.74 in group B. Regarding the intraoperative blood loss it was more significant in group B with the mean intraoperative blood loss as 76.67 ± 15.34 in group A and 116.36 ± 22.79 in group B. Postoperative pain was more in group B than in group A, so 6 patients (33.3%) postoperative weak opiate analgesia in group A for less than 24 hours, while 16 patients (72.7%) needed postoperative weak opiate analgesia in group B. Hospital stay was 2.44 ± 0.51 in group A and 2.91 ± 1.02 in group B. Conclusion PCNL is a safe and effective procedure for management of renal stones in children, with accepted stone clearance rates and postoperative morbidity in addition to short hospital stay.
