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.\r\nHowever, this may cause many complications ranging from stent-related irritative lower urinary tract\r\nsymptoms (LUTS) to advanced renal failure. Although complications such as encrustations, proximal, and distal\r\nmigrations within the pelvicaliceal system (PCS) are reported frequently in the literature, stent displacement\r\ninto the contralateral ureter is rare and not previously described at our knowledge
