Brief Summary
The goal of this study is to check if the study device, the Akyva System, is safe to use and to find out if it has any possible side effects. Researchers will see if the study device can help you urin...
Eligibility Criteria
Inclusion
- Are male or female, as assigned at birth, aged ≥ 22 years of age.
- Presents lower urinary tract (LUT) symptoms that have been ongoing for at least the past 90 days prior to consent.
- Is currently performing clean intermittent catheterization (CIC) for urinary retention at a rate of ≥3 catheterizations per day, as reflected in a 3-day self-catheterization record taken within 180 days prior to consent or a 7-day self-catheterization record collected between day of consent and before the implant procedure.
- Have a post-void residual (PVR) volume ≥ 300 mL as evaluated at least twice within 180 days prior to screening or during screening. NOTE: Individuals unable to void any volume without catheter assistance, i.e. complete retention, are considered to have a PVR equivalent to pre-catheterization volume.
- Have prior history of recurrent urinary tract infection (UTI) with at least two episodes of infection in the past 180 days or currently managing recurrent UTIs with antibiotic medication (e.g. Hiprex).
- Urodynamic measurements consistent with detrusor underactivity. NOTE: Urodynamics performed within the last 365 days prior to consent are acceptable. (1) Bladder contractility index (BCI) \< 100 (in Males) (2) Qmax \< 15 mL/s and PdetQmax \< 20 cmH2O (in Males or Females).
- Are medically fit to withstand abdominal-pelvic surgery under general anesthesia, as evaluated by standard-of-care pre-operative surgical clearance.
- Females of childbearing potential must agree to the use of contraception for the duration of the study
- Are able to understand the risks associated with the study, are willing and able to provide written informed consent prior to any study-related activity, willing and capable of participating in all follow up assessments and willing to undergo all study assessments as described at an approved clinical investigator site.
Exclusion
- Have or are scheduled for implant of any active implantable medical device (e.g., pacemaker or intrathecal or infusion pump) or have metallic implants/fragments in the abdomen or pelvis (e.g., piercings or hip replacement). Individuals with fully explanted sacral neuromodulation (SNM) or other implantable medical devices may participate. Individuals with implanted and inactive SNM devices may participate.
- Have a documented allergy to tissue contacting Akyva System materials: tecothane, titanium, silicone, epoxy, stainless steel, nickel/cobalt/chromium/molybdenum, polyether ether ketone (PEEK), platinum, iridium, polymethylpentene (TPX), polycarbonate, polyester.
- In the opinion of the Investigator(s), participants who need or are likely to need magnetic resonance imaging (MRI) as part of their routine care for the duration of the study. If MRI is clinically indicated, during or after the study, explant of the Akyva System may be required
- Have hypersensitivity reaction (Types I-IV) to iodine-containing radiographic contrast dyes, or any documented prior severe allergy resulting in anaphylaxis/intubation.
- Have active infection requiring treatment with antibiotics at Screening, unless cleared before Akyva System Surgical Implant (Visit 2).
- Have any history of prior major pelvic or abdominal surgery that would, in the opinion of the Surgical Co-Investigator, increase the risk of injury to abdominal or pelvic organs during the implant procedure.
- Have any history of genitourinary reconstruction surgery or is considering genitourinary reconstruction surgery within the next 24 months.
- Have a significant clinical finding that would, in the opinion of the Surgical Co-Investigator, increase the risk associated with the implant procedure (e.g. ascites, severe inflammatory disease, bleeding or clotting disorder, other interfering devices etc.).
- Have suboptimally controlled Type I or Type II diabetes, as defined by an HbA1C ≥ 7.0%. NOTE: HbA1C results reported within the last 60 days prior to consent are acceptable.
- Have documented renal dysfunction, defined as an estimated glomerular filtration rate (eGFR) ≤ 50 mL/min/1.73 m² or evidence of hydronephrosis on renal ultrasound or CT urogram. NOTE: Renal function panel and renal ultrasound or CT urograms performed within the last 365 days prior to consent are acceptable.
- Have any history of dialysis or kidney transplant.
- Have a history of kidney or bladder stones within the last 10 years.
- Have any history of bladder cancer.
- Have any history of pelvic cancer diagnosis (e.g. uterine, ovarian, rectal), unless disease-free for ≥ 2 years measured from the day of consent.
- Have any history of radiation cystitis.
- Have locally advanced malignancy or metastatic disease within the past five (5) years from the day of consent, with the exception of adequately treated or cured malignancy with no evidence of disease.
- Have had botulinum toxin injection in the bladder or pelvic floor in the past 6 months measured from the day of consent.
- Have any history of bladder-involved fistula or bladder diverticulum.
- Have any history of major bladder reconstructive surgeries.
- Have a bladder compliance \< 20 mL/cmH2O measured during urodynamic study. NOTE: Urodynamic performed within the last 365 days prior to consent are acceptable.
- Have a current underlying diagnosis of neurogenic bladder.
- Have any history of an overactive bladder or LUT symptoms suggestive of an overactive bladder.
- Have an iatrogenic cause of UAB symptoms in the opinion of the PI.
- Currently using an indwelling (e.g. Foley) catheter for bladder emptying, with an exception for nighttime-only use.
- Females who have had any prior abdominal sacrocolpopexy procedure for pelvic organ prolapse.
- Males with history of elevated PSA or prostate cancer undergoing further evaluation or treatment.
- Participants who are unable to discontinue anticoagulant therapy for the implant procedure.
- Females of childbearing potential who are pregnant, not using medical birth control or who are planning to become pregnant during the anticipated study period.
- Predicted life expectancy of less than one year from the day of consent.
- Have any history of diagnosis of bladder outlet obstruction secondary to bladder neck stenosis, BPH or urethral stricture disease. Participants with prior surgical treatment of BPH with no clinical evidence of obstruction and do not require routine MRI may be included
- Any condition that, in the Investigator's opinion, would preclude participation in the study (e.g., have a medical condition that may interfere with interpretation of study results, inability to adhere to the visit schedule, poor cognitive abilities, poor compliance with treatment regimen, or poor dexterity to use the system etc.).
- Previously (within 5.5x the terminal half-life (drug trial) or 8 weeks (device trial) of the screening visit) or currently enrolled in another investigational drug or device trial.
- Vulnerable persons such as prisoners, mentally-disabled or cognitively impaired, homeless or economically disadvantaged, nursing home patients, or others requiring legally authorized representatives.
- Participants that work in an environment with exposures to high levels of electromagnetic interference such as working with high powered electrical equipment.
