As the organ donation enlarges, it compresses on urethra. Symptoms include difficulty in passing urine, pain during passage of urine and infections due to stagnant urine. Medications are available in early stages like alpha blocker group of drugs. Later stages, surgery is advised. You can consult an urologist for it. All the blood tests given are within normal range.
