Predictors for Retrograde Ureteral Stenting Failure as an Initial Drainage Method for Emergent Complicated Acute Calculus Obstructive Uropathy
ObjectiveTo define predictors for initial retrograde ureteral stenting (RUS) failure with the need for the percutaneous nephrostomy (PCN) insertion as a drainage method in patients with complicated acute calculus obstructive uropathy. MethodsWe undertook a retrospective evaluation of...

| description | ObjectiveTo define predictors for initial retrograde ureteral stenting (RUS) failure with the need for the percutaneous nephrostomy (PCN) insertion as a drainage method in patients with complicated acute calculus obstructive uropathy.
MethodsWe undertook a retrospective evaluation of patients who presented with complicated obstructive calculus uropathy (acute renal failure or obstructive pyelonephritis) between January 2016 and January 2020. Patients in whom there was failure to visualize ipsilateral ureteric orifice and those with extrinsic ureteral obstruction were excluded. Patient demographics and radiological data including stone site, hydronephrosis grade, maximum transverse stone diameter, periureteral density (PUD) and pericalcular ureteric thickness (P-CUT) at the maximum transverse stone diameter were assessed using non-contrast computed tomography at the time of admission.
ResultsThe study included 256 patients who were managed initially by RUS trial. Of them, 48 (18.8 %) had RUS failure. The presence of acute pyelonephritis, increased maximum transverse stone diameter ≥ 9.5 mm, P-CUT ≥ 7.5 mm, and PUD at stone level ≥ 17.5 HU were risk factors associated with RUS failure (P = 0.007, 0.002, < 0.001, and < 0.001, respectively).
ConclusionInitial radiological stone and ureteric characteristics, in addition to the clinical diagnosis of obstructive pyelonephritis, can be used to determine PCN insertion as the preferred option over RUS for urinary drainage. |
