The advent of the single-port robotic platform enables a retroperitoneal approach while preserving the advantages of robotic reconstruction. We report early outcomes of single-port robot-assisted BMG ureteroplasty and pyeloplasty from a single-center experience.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>We retrospectively reviewed 16 consecutive patients who underwent single-port robot-assisted ureteroplasty or pyeloplasty with BMG between September 2020 and June 2025, performed by a single surgeon. Indications included complex ureteral strictures or redo pyeloplasty. The primary outcome was clinical success, defined as freedom from ureteral stenting and\/or percutaneous nephrostomy at 90 days. Perioperative outcomes, complications, and short-term follow-up were analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The cohort had a mean age of 45 \u00b1 14.9 years and a median stricture length of 3 cm (interquartile range [IQR]: 2\u20133). Most procedures were performed via a retroperitoneal low anterior access (75%). Reconstructive procedures included ureteroplasty (50%), pyeloplasty (43.8%), and combined reconstruction (6.3%). Median operative time was 183 minutes (IQR: 150\u2013215), with minimal blood loss and a median length of stay of 11 hours (IQR: 8\u201329). At 90 days, 87.5% of patients were stent-free and 93.7% were nephrostomy-free. Thirty-day complications occurred in 25% of patients, predominantly Clavien\u2013Dindo grade IIIa. The median follow-up was 14.5 months (IQR: 4.8\u201318.5).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Single-port robot-assisted BMG ureteroplasty and pyeloplasty are feasible and effective for complex ureteral and UPJ strictures, including redo cases. This approach offers acceptable perioperative morbidity, favorable short-term functional outcomes, and a high rate of outpatient management using a retroperitoneal approach.
