“…The length of the appendix is finite, replacing approximately 3-cm ureteral defects on average, and usually it fails to bridge long-segment strictures or a defect is left-sided. 49 Adequate mobilization of the right colon and cecum can achieve tension-free anastomosis between the appendix and the proximal, mid or distal ureter of the right side. Richter et al presented the longest follow ups of 4, 7 and 15 years for three children, respectively, confirming that the appendiceal replacement can transport urine satisfactorily and maintain good renal function in select patients.…”

Long ureteral defects have remained a challenge to urologists for a long time. Bowel interposition, including ileal ureter, appendiceal interposition and reconfigured colon substitution, has gained wide acceptance, even though it is a complicated procedure and associated with some potential complications. Mucus obstruction and metabolic disorders are common complications of intestinal substitution. To circumvent these troubles, modified techniques, such as tapering the bowel graft, intestinal onlay flap and the Yang-Monti procedure, are used. In particular, Yang-Monti ileal ureter replacement is a highly effective option for ureteral reconstruction, and the incidence of complications would be significantly reduced in select patients. After being combined with the Boari flap or psoas hitch technique, the length of intestinal segment used can also be significantly reduced. Most recent long-term results suggest that ileal ureter replacement with antireflux anastomosis seems to be remarkably free of complications, and we highly praise the distal nipple valve technique. Appendiceal interposition is available for patients with normal appendix, and usually this procedure is limited to reconstructing the right ureter. Appendiceal onlay ureteroplasty has emerged as a feasible and effective option to manage patients with complex proximal and midureteral strictures of the right side. The colon is rarely used for ureteral reconstruction because of its large caliber and mucous surface area. However, a reconfigured colon segment is a good substitute to reconstruct long-segment ureteral defects, and longterm follow up confirmed minimal complications and improved renal function. This review provides a comprehensive perspective on complex ureteral reconstruction and replacement using intestinal segments, in particular, ileal ureter replacement.

“…Use of the appendix as a ureteral substitute or as an onlay flap has also been described for complex right mid or upper ureteral stricture repair, initially in the open (42–44) or laparoscopic (45, 46) settings. Recently, Yarlagadda et al published a case report of robotic appendiceal interposition for right-sided ureteral stricture disease (47). In this case, a 5 cm obliterative ureteral stricture secondary to recurrent ureterolithiasis and pyelonephritis was repaired with interposition of the appendix between the proximal and distal healthy ureter.…”

Robot-assisted laparoscopic (RAL) surgery is a safe, minimally invasive technique that has become more widely used in pediatric urology over recent decades. With several advantages over standard laparoscopy, robotic surgery is particularly well-suited to reconstructive surgery involving delicate structures like the ureter. A robotic approach provides excellent access to and visualization of the ureter at all levels. Common applications include upper ureteral reconstruction (e.g., pyeloplasty, ureteropelvic junction polypectomy, ureterocalicostomy, and high uretero-ureterostomy in duplex systems), mid-ureteral reconstruction (e.g., mid uretero-ureterostomy for stricture or polyp), and lower ureteral reconstruction (e.g., ureteral reimplantation and lower ureter-ureterostomy in duplex systems). Herein, we describe each of these robotic procedures in detail.
