The "UW-LPHS Test": A New Test to Predict the Outcome of Renal Autotransplant for Loin Pain Hematuria Syndrome.

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.
