Percutaneous peritoneal dialysis catheterization with visualization of rectovesical/rectouterine pouch under ultrasound guidance: a retrospective study of 507 patients.

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
backgroundThe success of urgent-start peritoneal dialysis (USPD) relies on well-functioning catheters and safe, minimally invasive catheterization methods with minimal complications. However, there are currently no large-scale trials demonstrating the significant superiority of any peritoneal dialysis (PD) catheterization technique.
methodsWe conducted a retrospective analysis of 507 patients who underwent “percutaneous peritoneal dialysis catheterization with visualization of rectovesical/rectouterine pouch (RP) under ultrasound guidance (we named ‘PDCVRU method’)” from September 2018 to February 2024. The outcomes of follow-up at 1 month and 1 year were observed.
resultsIn this study, all patients received USPD within 48 h except one with technical failure. Of 506 patients with successful catheterization, 377 patients started low-volume manual fluid-exchange PD, which was gradually titrated to the standard peritoneal fluid volume used in continuous ambulatory peritoneal dialysis (CAPD); these patients comprised the CAPD group. The remaining 129 patients initiated low-volume tidal automated peritoneal dialysis (APD) with progressive titration to standard peritoneal fluid volume and were designated as the APD group. The overall success rate of catheterization was 99.8%, with no significant surgical bleeding, bladder injury, or intestinal perforation. At 1-month follow-up, there were 2 cases (0.4%) of peritonitis, 1 case (0.2%) of tunnel infection, 4 cases (0.8%) of transient leakage, and 11 cases (2.0%) of catheter malfunction. No significant differences were observed in the incidence of complications or catheter survival rate between the APD group and the CAPD group during the first month. At 1-year, data from 465 patients were available for analysis. There were 20 patients (4.3%) with catheter malfunction, 9 cases (1.9%) of exit or tunnel infections, 35 cases (7.5%) of peritonitis. The 1-year catheter-related survival rate was 95.8%.
conclusionsThe ‘PDCVRU method’ applied in this study has been proven to be a safe and effective catheterization technique suitable for independent performance by nephrologists, offering significant advantages for USPD. CLINICAL TRIAL NUMBER: Not applicable.
