Ureteral Obstruction

Ureteral obstruction occurs when the tubes that carry urine from the kidneys to the bladder become blocked or narrowed. This can happen due to kidney stones, blood clots, tumors, or scar tissue. The blockage prevents normal urine flow, leading to pain, swelling, urinary problems, and potential kidney damage if untreated. Symptoms may include discomfort in the back or side, frequent urination, or nausea. Treatment depends on the cause and severity, ranging from medications to procedures that remove or bypass the blockage, helping restore normal urine flow and protect kidney function.
