Keywords:
lithiasis, extracorporeal shock wave lithotripsy, pediatric hospitals.Abstract
Introduction: In recent years, an increase in urinary lithiasis has been observed in all ages. Extracorporeal shock wave lithotripsy is the first line treatment in children.
Objectives: To describe the results for the treatment of urinary lithiasis in pediatric patients.
Methods: A retrospective, descriptive and longitudinal study was conducted in 37 patients of the Hospital Pediátrico Docente Centro Habana with diagnosis of urinary lithiasis treated by extracorporeal lithotripsy from January 2016 to December 2019.
Results: Male sex was predominant. The mean age was 14.08 years (range 3-19 years). They had a history of 17 previous surgeries for lithiasis and endourological procedures predominated (41.2%). Lithiasis of 10 to 20 mm (86.5%), renal location (54.1%) and lithiasis with a density of less than 400 HU (48.6 %) were more common. Previous urinary diversion (JJ catheter in 27.0%) was required in 37.8% of the patients. 32.4% presented complications, the most frequent being the lithiasic street (21.6%). Additional interventions were required in 16.2%. Retreatment was necessary in 8.1% of the cases. The 70.3% were free of lithiasis at one month, with a success rate at three months of 91.9%.Complications predominated, Grade III-b (50.0%), according to Clavien-Dindo.
Conclusions: The application of extracorporeal lithotripsy has had satisfactory results in the Pediatric Teaching Hospital Centro Habana. It is effective, safe and should be considered as the first treatment alternative in pediatric patients.
