Single-Port Robotic-Assisted Excision of the Urachal Remnant in an Adult Female: A Case Report.

Urachal anomalies and their associated disease processes are quite rare in pediatric populations and even rarer in adults. Although often asymptomatic, patients with symptoms can be treated with a combination of surveillance, antibiotics, and sometimes surgical resection. In this case, we describe our experience using the single-port robotic approach for the excision of a symptomatic urachal remnant. The patient presented with a chief complaint of urinary frequency, dysuria, intermittent hematuria, and right flank pain. A CT scan of the abdomen and pelvis revealed a bladder wall thickening at the dome of the bladder measuring 2.6 x 3.6 x 1.5 cm with concerns for adenocarcinoma. The patient subsequently underwent a biopsy, which was benign. The patient's symptoms persisted, and she elected to undergo surgical resection. Postoperatively, her symptoms resolved, and she was satisfied with her treatment outcome. This case exemplifies the feasibility of the single-port robotic approach to urachal remnant excision, with further applicability to simple transabdominal robotic bladder surgery.
