Q62.11

Clinical Causes: Congenital malformation during fetal development causing abnormal narrowing or blockage Genetic factors passed down from parents that affect urinary tract development Rarely, associated syndromes or other congenital anomalies impacting urinary structures

Key Symptoms: Frequent urinary tract infections Flank pain or discomfort on one side of the body Reduced or absent urine output from the affected kidney Persistent abdominal or back pain Nausea or vomiting in more severe cases A palpable mass in the abdomen in some instances In some cases, no symptoms are present until complications occur

Diagnosis Path: Diagnosis typically involves a combination of imaging studies and clinical evaluation, including: - Ultrasound: To visualize the kidneys and detect dilation or swelling - Intravenous pyelogram (IVP): X-ray imaging after contrast dye to observe urine flow - Magnetic Resonance Urography (MRU): For detailed images of the urinary tract - Renal function tests: To assess how well the kidneys are working These methods help determine the presence, location, and severity of the obstruction.

Treatment Protocols: Treatment options depend on the severity of the occlusion and the degree of kidney impairment: - Observation: Small, asymptomatic obstructions may be monitored regularly - Surgical intervention: Procedures such as pyeloplasty, which involves removing the narrowed segment and reconnecting the healthy portions of the ureter and renal pelvis - Endoscopic procedures: Minimally invasive techniques to dilate or remove the blockage in suitable cases - Postoperative care includes regular follow-up imaging to verify the success of treatment and ensure there is no recurrence Early detection and appropriate management are essential to prevent long-term kidney damage.
