Retroperitoneal robot-assisted laparoscopic nephroureterectomy using the da Vinci Xi and SP systems: Initial experiences in cadaveric models.
Article in Investigative and clinical urology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo investigate the feasibility and optimal port placements of robot-assisted laparoscopic nephroureterectomy (RANU) via the retroperitoneal approach in the lateral decubitus and supine positions using the da Vinci Xi (DVXi) and da Vinci SP (DVSP) systems. MATERIALS AND
methodsWe performed lateral decubitus extraperitoneal RANU on the right side and supine extraperitoneal RANU on the left side using the DVXi and DVSP systems without repositioning in two fresh cadavers. In addition, paracaval and pelvic lymphadenectomies were performed simultaneously during both surgical procedures. The operative time of each procedure was calculated, and the technical details associated with these procedures were evaluated.
resultsLateral decubitus and supine extraperitoneal RANU using the DVXi and DVSP systems were achieved without repositioning. The surgeon console time ranged from 89 to 178 minutes, and no major technical complications were observed. However, carbon dioxide insufflation into the abdominal cavity was observed owing to a peritoneal breach during the creation of the surgical workspace, particularly in the supine position. Compared with the DVXi system, the DVSP system was more suitable for RANU using the retroperitoneal approach, except for renal handling.
conclusionsThe DVXi and DVSP systems are feasible for performing lateral decubitus and supine extraperitoneal RANU without patient repositioning. The lateral decubitus position may be better than the supine position, and the DVSP system is more suitable for retroperitoneal RANU than the DVXi system. Nevertheless, further studies should be performed in clinical settings to validate our results.
