What is obstructive uropathy?

Obstructive Uropathy Explained - Kidney Risk & Relief

"Blocked pipes bring big problems" means urinary tract blockages lead to health complications. Blockages in the urinary tract can cause discomfort, pain, and serious damage. Obstructive uropathy is a chronic or acute condition for all demographics and needs prompt medical care.

Definition of Obstructive Uropathy

Obstructive uropathy is a functional or structural hindrance or blockage in the urinary tract that stops normal urine flow. This condition of blocked urine flow leads to renal failure or dysfunction. It can occur in any area, such as from the cast and the renal tubules to the urethral meatus.

Obstructive uropathy affects both kidneys, impacting urinary output and serum creatinine. It follows a bimodal distribution pattern, with two peaks occurring in infants and the older population.
 

Cause of Obstructive Uropathy

Obstructive uropathy occurs when the urinary system is obstructed and fails to drain urine. This situation forces urine to back up and injures the kidneys. Here are a few causes of blockage: 

1. Kidney Stone: Kidney stones are carried down the ureters to the bladder from the kidney.  
2. Strictures: It is a tube narrowing, in the uterus or the bladder neck. A stricture limits urine flow, leading to obstructive uropathy.
3. Benign Prostatic Hyperplasia (BPH): BPH is a non-cancerous enlargement of the prostate gland and surrounding tissues in males. It constricts the urethra and creates urination difficulties.
4. Pregnancy: During pregnancy, the growing uterus puts pressure on the urinary tract or bladder. This pressure results in bladder emptying difficulties, frequent urination and kidney dysfunction.
5. Tumour: In case a tumour grows in the urinary tract, the surrounding area of the bladder, or the prostate for males, it can obstruct urine flow. Growing tumours also put pressure on the urethra or bladder and cause obstructive uropathy.  
6. Uterine Prolapse: It compresses the ureters and blocks the tube that transfers urine from the kidney to the bladder. This situation leads to obstructive urine flow and results in kidney swelling and failure.
   
    

Obstructive Uropathy Symptoms

Symptoms appear suddenly or slowly and may include:

• Severe flank pain
• Vomiting and nausea
• Fever
• Weight gain
• Frequent urination
• Urinal bleeding
• Dribbling of urine
• Urinary incontinence
• Weak urine stream
• Burning and foul-smelling during urination
   

Treatment of Obstructive Uropathy

Medications for obstructive uropathy use are as follows:

1. A drain or ureteral stent will be placed in the renal pelvis to relieve symptoms for a short time.
2. Use of nephrostomy tubes for draining urine through the back of the kidneys.   
3. Placement of a Foley catheter through the urethra into the bladder drains backed-up urine effectively.
4. Prescribe antibiotics to deal with urinary tract infections and reduce physical problems.
5. Medicines can help relax the prostate muscles for easier urination.
    

Obstructive uropathy is a chronic or acute condition that constrains normal urinary flow and leads to kidney problems. It occurs in the surrounding areas of renal tubules to the external urethral tube due to kidney stones, bladder stones, pregnancy, and the growth of tumour cells.

Urinary difficulties like bladder emptying problems, burning sensations during urination, and foul-smelling urine are major symptoms.
