Urinary tract stones are very common among the adult population, affecting between 8% and 12% of people in Cuba, making them the third most common urological disease after infections and prostate disease. We present the case of a 59-year-old male patient with a four-year history of aching left lumboabdominal pain and hematuria. Imaging studies (renal ultrasound and plain and contrast-enhanced renal computed tomography) revealed a 13 mm stone located at the urethra-pelvic junction of a trifid pelvis of the left kidney, with moderate pyelocaliectasia. It was concluded that the stone was a congenital anomaly of the renal pelvis, based on its shape in a trifid pelvis. A left percutaneous nephrolithotomy was performed using minimally invasive surgery. The patient made a satisfactory outcome and was discharged four days after the procedure
