The causes of soreness and bloating at the end of urination include prolonged holding of urine, urinary tract infections, urinary stones, prostatitis, etc., which need to be treated after clarifying the cause of the disease. 1. Prolonged holding back of urine will cause the pressure in the bladder to rise and urine reflux will occur, and urine reflux into the renal pelvis will be manifested as a feeling of soreness and distension in the lower back. 2. Infections of the urinary system are due to inflammation that irritates the mucous membrane of the urethra, which may produce a feeling of soreness after urination. 3. Urinary stones, such as ureteral stones or irritation of the ureteral epithelium, may cause spasms in the ureter after urination, resulting in a feeling of soreness and distention. 4. Prostatitis can cause congestion and edema of the prostate gland due to inflammation and stimulation of the prostate tissue, resulting in a feeling of soreness after urination. Due to the diversity of causes, it is recommended to go to the hospital to receive timely examination, clear the cause of the disease, and then actively treat to alleviate the discomfort.
