To review the available literature on lingual mucosa graft (LMG) ureteroplasty and gain a better understanding of the safety, success rates and complications of LMG ureteroplasty for management of ureteric strictures.

A systematic literature review was performed based on the protocol, utilising searches in PubMed, MEDLINE, and EMBASE databases. All results were screened in detail, and a comprehensive full-text review was carried out on all relevant articles (Figure 1).

Of the 502 initially identified articles, 8 met inclusion criteria, reporting a total of 117 LMG ureteroplasties. 68 cases were carried out laparoscopically, and 49 cases were carried out using the robot-assisted approach (Figure 2). The overall successful outcome reported was 113 out of 117 (96.6%) cases, where 67 out of 68 (98.5%) and 46 out of 49 (93.9%) were performed via laparoscopic and robotic-assisted approaches, respectively. The complication rate was 23 out of 117 (19.7%) cases, with a less than 1% (1/117) rate of severe complications (Clavien-Dindo≥ III). Peri-operative data and outcomes are summarised in Figure 3.

Lingual mucosa graft ureteroplasty demonstrated a high success rate for the management of ureteric strictures, with a high safety profile in both robotic and laparoscopic approaches. However, future prospective studies with a larger patient cohort, encompassing varying ureteric stricture lengths and extended follow-up periods, are warranted to validate these findings further.
