Angiotensin converting enzyme inhibitors are thought to be beneficial, as they reduce intraglomerular pressure and, presumably, reduce renal tubular congestion with RBCs.Possible treatment regimens

General
Angiotensin inhibition
Reduce the risk of nephrolithiasis

Pain control
Opioid therapy
Inpatient therapy
Intravenous opioid regimen
Antiemetic drugs
Pruritus management
Maintenance therapy between pain exacerbations

Invasive therapy
Implantable drug delivery system
Surgical renal denervation
Renal autotransplantation
Nephrectomy (NOT recommended)
Other invasive therapies (but not proven effective)
Pulse radio frequency
Celiac plexus block
Intraureteric capsaicin infusionSurgery (autotransplantation) is thought by some to be of benefit in selected individuals and advocated in some centres, but usually considered the last resort.Physicians discourage surgery, as LPHS symptoms often re-occur after autotransplantation. Epidemiology
LPHS is listed as a rare disease in the US National Institute of Health Rare Diseases database. While exact numbers worldwide are not available, the primary LPHS research clinic located in Ohio has over 200 patients. In addition, several hundred other patients have been reported in one study as of 2006. The prevalence of LPHS is estimated  at about 0.012 percent, which qualifies LPHS as a rare disease (prevalence less than 0.07 percent) according to the Rare Diseases Act of 2002. Those affected are usually young, with an average age of 31 years, and 70% to 80% are women. See also

Diagnosis
Stenoses of the vascular type are often associated with unusual blood sounds resulting from turbulent flow over the narrowed blood vessel. This sound can be made audible by a stethoscope, but diagnosis is generally made or confirmed with some form of medical imaging. See also
