Single-port robotic-assisted pyeloplasty (SP-RP) has gained prominence as a minimally invasive approach for treating ureteropelvic junction obstruction (UPJO), particularly in younger patients where cosmetic outcomes and reduced postoperative discomfort are priorities. Moreover, the Supine Anterior Retroperitoneal Access (SARA) technique offers a novel and effective pathway for performing SP-RP. Critical topics include patient selection, with emphasis on symptomatic hydronephrosis, renal function assessment, and anatomical considerations. Detailed operative steps, from positioning to anastomosis, underscore the importance of minimizing intraoperative bleeding and ensuring tension-free suturing to reduce complications such as ureteral ischemia and stenosis. Postoperative management, including stent removal and follow-up imaging, is also addressed.
