    ABSTRACT: Loin pain haematuria syndrome (LPHS) is a severe renal pain condition of uncertain origin and often resistant to treatment. Nephrectomy and renal autotrasplantation have occasionally been performed in very severe cases. Its pathogenesis is controversial. A 40-year-old hypertensive lady was diagnosed with LPHS after repeated diagnostic imaging procedures had ruled out any renal, abdominal or spinal conditions to justify pain. Notwithstanding treatment with three drugs, she had frequent hypertensive crises during which the loin pain was dramatically exacerbated. Vascular causes of the pain and hypertension were investigated and excluded. Her renal function was normal. The patient was referred to a multidisciplinary pain clinic, but had no significant improvement in her pain symptoms despite the use of non-steroidal anti-inflammatory drugs, adjuvant antidepressants and opioid-like agents. The pain and the discomfort were so severe that her quality of life was very poor, and her social and professional activities were compromised. Nephrectomy and renal autotransplantation have occasionally been performed in these cases. Since visceral pain signals flow through afferent sympathetic fibres, we felt that percutaneous catheter-based radiofrequency ablation of the renal sympathetic nerve fibres (recently introduced for the treatment of drug-resistant hypertension) could be valuable for pain relief. We treated the patient with radiofrequency ablation (Medtronic Symplicity Catheter) applied only to the right renal artery. After a 6-month follow-up, the patient is pain free and normotensive with all drugs withdrawn. She has experienced no hypertensive crises in the meantime. This observation suggests that percutaneous sympathetic denervation could prove to be an effective mini-invasive strategy for the treatment of chronic renal pain, and LPHS in particular.

    ABSTRACT: Abstract Objectives: To assess the role of laparoscopic renal denervation as a surgical option in loin pain-haematuria syndrome (LPHS), refractory to conservative treatment. Material and methods: Nine patients between 2000 and 2010 with a diagnosis of LPHS following extensive investigations. The data collection from medical records and electronic databases included demographic details, details of surgical procedures, perioperative outcomes, pain recurrences and ongoing analgesia requirements. A telephone follow-up was conducted after at least one year after the procedure for each patient using the Pain Impact Questionnaire (PIQ-6TM) to assess impact of pain on their quality of life. Results: Nine patients (nine women; median age 37 years) underwent 11 laparoscopic denervations. The median follow-up was 28 months. The median operative time was 150 min. There were no significant postoperative complications. In four patients (44%) laparoscopic denervation procedures were curative (median follow-up 70.5 months). The analgesic requirement was significantly reduced in 22% of patients. Telephone follow-up confirmed that 66.66% of the patients had better quality of life after the procedure. Conclusions: Laparoscopic renal denervation is a feasible and safe alternative to open procedures in patients with refractory LPHS, producing good outcomes in terms of pain-free rates and quality of life impact.

    ABSTRACT: There is increasing international attention in efforts to integrate palliative care principles, including pain and symptom management, into the care of patients with advanced chronic kidney disease (CKD). The purpose of this scoping review was to determine the extent, range, and nature of research activity around pain in CKD with the goal of (i) identifying gaps in current research knowledge; (ii) guiding future research; and (iii) creating a rich database of literature to serve as a foundation of more detailed reviews in areas where the data are sufficient. This review will specifically address the epidemiology of pain in CKD, analgesic use, pharmacokinetic data of analgesics, and the management of pain in CKD. It will also capture the aspects that pertain to specific pain syndromes in CKD such as peripheral neuropathy, carpal tunnel syndrome, joint pain, and autosomal dominant polycystic kidney disease.
