OBJECTIVES: The objectives of this pilot study were twofold. First, we aimed to elicit whether the "UW-LPHS test" definitively localizes pain from patients' loin pain hematuria syndrome to the ureter and thus proves our hypothesis. Second, we aimed to understand whether a positive UW-LPHS test predicts a successful outcome after renal autotransplant. MATERIALS AND METHODS: The UW-LPHS test is described in detail in this manuscript. Briefly, 0.5% bupivacaine is injected into the ureter of the affected side and kept there using a balloon catheter for 5 minutes. RESULTS: All six patients studied had complete pain relief at a mean follow-up of 9.2 months after renal autotransplant. All patients were successfully weaned from opioids and have returned to a normal lifestyle. CONCLUSIONS: The UW-LPHS test can be used to predict renal autotransplant outcomes and should be applied to all patients who are being considered for this operation.
