A ureteral bypass device (10) and procedure suitable for performing internal urinary diversions within patients, including patients such as humans and veterinary animals (cats and dogs). The device (10) includes a nephrostomy catheter (12) having a proximal end (24), an oppositely-disposed distal end (18), and means for securing the distal end (18) within the renal pelvis of a kidney of a patient, a cystostomy catheter (14) having a proximal end (24), an oppositelydisposed distal end (20), and means for securing the distal end (20) of the cystostomy catheter (14) within the urinary bladder of the patient, and an adaptor (16) fluidically connected to the proximal ends (24) of the nephrostomy and cystostomy catheters (12,14) so as to fluidically connect the nephrostomy and cystostomy catheters (12,14) together through the adaptor (16). If implanted subcutaneously, the adaptor (16) may include an entry site (30) that has a selfsealing septum that can be accessed with a needle while the device (10) remains implanted and secured under the skin to subcutaneous tissue. |
