This systematic review assessed laparoscopic and robot-assisted management of symptomatic calyceal diverticula. Nine studies were included in a qualitative synthesis. Across studies, no Clavien-Dindo Grade III–IV complications were reported; flank-pain recurrence ranged from 0% to 28.5%, and diverticulum recurrence from 0% to 33.3%. None of the patients with either recurrence required reoperation. The authors considered these approaches feasible, with favorable outcomes in selected patients, including those with complex anatomy or prior failed endourological treatment, while noting that the evidence base is limited.
Key findings
- Nine studies were included in the qualitative synthesis.
- No Clavien-Dindo Grade III–IV complications were reported in any of the nine studies.
- Flank-pain recurrence ranged from 0% to 28.5%, and diverticulum recurrence from 0% to 33.3%.
- None of the patients with flank-pain or diverticulum recurrence required reoperation.
Why it matters
The review summarizes outcomes for surgical approaches that may be considered when symptomatic diverticula have complex anatomy or endourological treatment has failed. The reported absence of severe complications and lack of reoperations after recurrence are relevant when weighing these options, but the wide outcome ranges and limited evidence mean results should be interpreted cautiously.
What to keep in mind
The review included only nine studies, and the authors state that the available evidence remains limited.
