Double J stent migration in the contralateral ureter during robotassisted pyeloplasty: an unique complication

The placement of double-J (DJ) stent in the urinary tract is a part of urologic practice for many indications. However, this may cause many complications ranging from stent-related irritative lower urinary tract symptoms (LUTS) to advanced renal failure. Although complications such as encrustations, proximal, and distal migrations within the pelvicaliceal system (PCS) are reported frequently in the literature, stent displacement into the contralateral ureter is rare and not previously described at our knowledge
