In 2019, the patient started PANCREATIN (CREON) (Oral) 3600 unit. On 28-Apr-2021, the patient received first dose of mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular) 1 dosage form. On 11-Apr-2021, the patient experienced FLANK PAIN (Flank pain). On 16-Apr-2021, the patient experienced RENAL MASS (Mass on right kidney), BLOOD URINE PRESENT (Blood in urine) and BACTERIAL TEST POSITIVE (bacteria urine identified). On 04-May-2021, the patient experienced RENAL CANCER (Kidney cancer) (seriousness criterion medically significant). On 07-May-2021, the patient experienced BLADDER SPASM (Urinary tract infection like symptoms which was bladder spasm). On 11-May-2021, the patient experienced URINARY TRACT INFECTION (urinary tract infection).
