A Urological Twist: Literature Review, An Australian Experience and Management Algorithm for Knotted Ureteric Stents

Özet

Knotted ureteric stents remain a rare complication, with only 34 cases reported to date. They require prompt recognition and skilful managementto avoid ureteric injury. Knots more often occur at the proximal end of stents, have a male preponderance, are associated with multi-length stentsand relate to the J-coil configuration, which is affected by the renal pelvis anatomy, hydroureter and presence of urolithiasis. We present ourexperience of a knotted stent managed using holmium:yttrium aluminium garnet laser and traction. We also provide an updated literature reviewand recommend a treatment algorithm for this rare but important complication
