Nephrostomy tube and Drainage pouch
Treatment often depends on the nature of the blockage. First efforts involve draining urine from the kidney(s). This can be done with:
- A ureteral stent: a thin, hollow plastic tube is placed between the kidney and bladder, holding the ureter open to allow urine to drain.
- Nephrostomy: a catheter is placed (guided by X-ray or ultrasound) through the skin into the kidney to drain urine.
- After relief of the blockage, laparoscopic or open surgery may be performed to permanently relieve the blockage.
