A pyelo-ureteral stent is provided that combines the benefits of a stent having a lumen with the benefits of a lumen-less stent. In one example, the stent may be implanted in a patient for use during and after a pyeloplasty procedure. The provided stent includes a flexible tube having two separate lumens. Each lumen terminates prior to the stent's closed distal end, which enables a lumen-less ureteric limb at the stent's closed distal end. The lumen-less ureteric limb may have a smaller diameter than the rest of the stent, and may be positioned in a patient's ureter to bridge the pyeloplasty repair, thereby providing the benefits of a lumen-less stent. The flexible tube may be formed with at least one perforated coil for the drainage of urine and/or blood. The stent may be removed from the patient without the use of a cystoscopic procedure.
A pyelo-ureteral stent comprising:
A method of treating a patient with a pyelo-ureteral stent including a flexible tube including a closed distal end, the flexible tube formed to include a perforated perinephric coil and a perforated renal coil, wherein the perforated renal coil is closer to the closed distal end than the perforated perinephric coil, wherein the flexible tube includes a first lumen extending from a first open proximal end and terminating between the perforated perinephric coil and the perforated renal coil, wherein the flexible tube includes a second lumen extending from a second open proximal end and terminating between the perforated renal coil and the closed distal end such that the second lumen terminates before the closed distal end, and wherein the perforated perinephric coil and the perforated renal coil are disposed between the closed distal end and a junction of the first lumen and the second lumen, the method comprising:
