Purpose
In patients with loin pain hematuria syndrome (LPHS), a response to percutaneous renal hilar blockade (RHB) and a multidisciplinary team (MDT) evaluation predicts patient’s potential renal auto-transplantation (RAT) success.
Methods
A pain assessment was performed using a 0–10 numeric pain rating scale prior to a percutaneous RHB under CT guidance. If the pain score was reduced > 50% immediately after the RHB, patients were evaluated for RAT by a MDT. Pre-operative and 1-year post-operative quality-of-life surveys were administered to each RAT patient.
Results
43 LPHS patients were referred for RHB. Of the 38 patients who received a RHB, 31 had > 50% reduction in pain scores. Pre- and post-RHB mean pain scores were 6/10 and 0.7/10, respectively, in patients who had > 50% reduction in pain. 22 of the patients who responded favorably then proceeded to RAT. Twelve patients had at least 1-year follow-up after RAT. All patients had a meaningful decrease in their pain. Mean pain score at 1 year was 0.8/10 for an 85% overall reduction in pain. 92% of patients experienced a ≥ 50% reduction in pain at 1 year. Mean Beck Depression Inventory (BDI) score (0–66) 1 year after RAT decreased from 25.2 pre-op (moderate depression) to 12.8 post-op (minimal depression).
Conclusions
A MDT approach utilizing a RHB should be considered as a tool to select appropriate LPHS patients for RAT to achieve long-term success in reducing chronic pain and depression while increasing quality of life.
