Ureteral stenting and nephrostomy help restore urine flow through blocked ureters and return the kidney to normal function. Ureters are long, narrow tubes that carry urine from the kidneys to the bladder. They can become obstructed – and urine flow blocked – as a result of various conditions.

If the malignant obstruction precludes a stent placement, then percutaneous nephrostomy tube is a safe alternative. The findings of our review can help clinicians in using a personalized approach to choose either option in malignant ureteral obstruction.

Nephroureteral Tube/Stent (PCNU) - tube through skin often with pigtail in the renal pelvis but ending in the bladder. A “retrograde nephroureteral stent” instead uses the same tube as a nephrostomy tube for a patient with an ileal conduit but the tube passes through the urostomy ending in the renal pelvis.

Nephroureteral stents including antegrade, retrograde, or internal (double-J) stents are routinely placed by interventional radiologists. The purpose of this review is to provide a detailed and comprehensive description of indications, ...

There are few studies comparing the efficacy of ureteral double J stent (DJS) vs a percutaneous nephrostomy tube (PCN) in the setting of obstructive ureteral stones.

Jun 17, 2016 · A nephroureteral stent/nephroureterostomy enters the collecting system via a flank approach (like a PCN) with a locking loop in the renal pelvis, and extends down the ureter terminating in the bladder, allowing both internal and external drainage (Fig. 53.1B).

Jan 26, 2018 · Ureteric stents coiled in the renal pelvis to prevent moving out of place and dislodgement. Stents protrude through the ileal conduit. There are absolute indications for ureteral stent placement.

Mar 23, 2021 · In many centres, the two main treatment options include percutaneous nephrostomy (PCN) and retrograde ureteral stenting (RUS). The purpose of this study if to compare the efficacy and safety...

Sep 1, 2012 · In this study, we compared between the efficacy and complications of percutaneous nephrostomy (PCN) tubes and those of internal ureteral stents (e.g., double-J stents) used for relieving ureteral obstructions. A retrospective chart review was performed.

Conclusion: Percutaneous nephrostomy is a safe and better method of temporary urinary diversion than double J stenting for management of obstructive uropathy with lower incidence of complications. Key Words: Double J stenting, Percutaneous nephrostomy, Obstructive uropathy, Complications rate.
