Mesane stones are more common in men over the age of 50 and make up 5% of all urine system stones. Mesane stones are often identified accidentally during the investigation of patients with obstructive symptoms, and usually the patient’s complaints are scary and hematurial. Gigantic mesh stones can also cause hydronephrosis. Therefore, it is necessary to evaluate the upper urinary system with appropriate imaging methods and to work on kidney function tests.             A 72-year-old male patient applied to our clinic with a complaint of difficulty urinating and bleeding. Urinary system ultrasound (USG) has been detected by grade 2-3 dilatation in the bilateral kidney collection system. Uncontrasted stones of 9.1x6.7x6 cm that filled the urine were observed in the computer tomography of all the abdomen thin cut. The prostate size was 200 cc. 6 of the patient. On the day, an open systolithotomy operation was performed. A stone of 10x7x6 cm, weighing 270 grams, was extracted from the patient.             As in our case, it is rare that urethra stones make acute kidney dilatation, and in literature this publication is limited. Patofysiologically, it is believed that the urethra stones press on the bilateral producer orphis and that chronic irritation creates obstruction in the orphis by increasing the thickness of the urethra wall.                  As a result, mesh stones come to us with a variety of symptoms and clinics. As in our case, in cases with reduction in urine output and kidney dilatation, urine stones should be taken into account.  Bladder stones are more common in men over 50 years of age, but constitute 5% of all urinary system stones. Bladder stones are often detected incidentally during the investigation of patients with obstructive symptoms, and the complaints of patients are usually dysuria and hematuria (8). Also giant bladder stones can lead to hydronephrosis. Therefore, it is necessary to evaluate the upper urinary tract with appropriate imaging methods and to study renal function tests.             A 72-year-old male patient was admitted to our outpatient clinic with complaints of strain and bleeding. Urinary system ultrasonography (USG) showed bilateral dilatation of bilateral kidney collection system. Computed tomography of the abdomen revealed a 9,1x6,7x6 cm stone that filled the bladder. The prostate size was 200 cc. On the 6th day of his hospitalization, open cystolithotomy was performed. 10x7x6 cm, 270 g weight stone was extracted from the patient.             Acute renal dilatation of the bladder stones as in our case is rare and the literature is limited in this literature. Pathophysiologically, it is thought that bladder stones compress the bilateral ureter orifices and chronic irritation increases the bladder wall thickness and causes obstruction in the orifices.                  As a result, bladder stones present with various symptoms and clinical features. In our case, bladder stones should be considered in cases with reduced urine output and renal dilatation.
