OBJECTIVE: To describe surgical techniques and peri-operative outcomes with secondary robotic pyeloplasty (RP), and compare them to those of primary RP. METHODS: We retrospectively reviewed our multi-institutional, collaborative of reconstructive robotic ureteral surgery (CORRUS) database for all consecutive patients who underwent RP between April 2012 and September 2019. Patients were grouped according to whether they underwent a primary or secondary pyeloplasty (performed for a recurrent stricture after previously failed pyeloplasty). Perioperative outcomes and surgical techniques were compared using nonparametric independent sample median tests and chi-square tests; P <.05 was considered significant. RESULTS: Of 158 patients, 28 (17.7%) and 130 (82.3%) underwent secondary and primary RP, respectively. Secondary RP, compared to primary RP, was associated with a higher median estimated blood loss (100.0 vs 50.0 milliliters, respectively; P <.01) and longer operative time (188.0 vs 136.0 minutes, respectively; P =.02). There was no difference in major (Clavien >2) complications (P =.29). At a median follow-up of 21.1 (IQR: 11.8-34.7) months, there was no difference in success between secondary and primary RP groups (85.7% vs 92.3%, respectively; P =.44). Buccal mucosa graft onlay ureteroplasty was performed more commonly (35.7% vs 0.0%, respectively, P <.01) and near-infrared fluorescence imaging with indocyanine green was utilized more frequently (67.9% vs 40.8%, respectively; P <.01) for secondary vs primary repair. CONCLUSION: Although performing secondary RP is technically challenging, it is a safe and effective method for recurrent ureteropelvic junction obstruction after a previously failed pyeloplasty. Buccal mucosa graft onlay ureteroplasty and utilization of near-infrared fluorescence with indocyanine green may be particularly useful in the re-operative setting.
