Ureteral Stents Versus Percutaneous Nephrostomy for Initial Urinary Drainage

Ureteral Stents Versus Percutaneous Nephrostomy for Initial Urinary Drainage in Children With Obstructive Anuria and Acute Renal Failure Due to Ureteral Calculi: a Prospective, Randomized Study

To compare percutaneous nephrostomy (PCN) versus double J stent (JJ) as an initial urinary drainage in children

To compare percutaneous nephrostomy (PCN) versus double J stent (JJ) as an initial urinary drainage in children with obstructive calcular anuria and acute renal failure due to ureteric calculi to identify selection criteria for initial urinary drainage method to improve drainage, to decrease complications and to facilitate subsequent definitive clearance of stones as this comparison is lacking in literature

Inclusion Criteria:

• children ≤12 years old presenting with Obstructive Anuria and Acute Renal Failure due to bilateral ureteric stones

Exclusion Criteria:

• Patients with grade 0-1 hydronephrosis
• fever, pyonephrosis or sepsis.
• any contraindication to both methods of drainage (urinary diversion, urethral stricture or uncontrolled coagulopathy).
