Feasibility of a single session retrograde endoscopic laser lithotripsy of two large stones located in a bifid urinary tract. Presentation of a rare case
A 76 year-old male presented with urosepsis and acute renal injury secondary to obstruction by a 13 mm stone located in the common segment of a bifid left ureter. A second 10 mm stone was detected in the mid calyx of the lower moiety of the kidney. Drainage of both moieties with two double-J stents was initially performed. Following recovery from urosepsis a retrograde endoscopic semirigid and flexible laser lithotripsy of the distal and proximal stone respectively was performed resulting in stone clearance. Although retrograde ureterolithotripsy has been presented in the past, to the best of the authors’ knowledge, this is the first description of flexible retrograde intrarenal lithotripsy performed through a bifid ureter.
