1 · What the graph read from it

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.

2 · The registry

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

backgroundPostoperative retraction is a significant limitation of traditional penile lengthening procedures that rely solely on suspensory ligament release. This retraction can lead to dissatisfaction among patients seeking enhancement. To address this issue, a novel two-step lengthening technique has been developed, which combines suspensory ligament release with an autologous dermal-fat graft and reinforcement using spermatic cord-associated fat.

objectiveTo evaluate the efficacy and safety of this innovative two-step lengthening technique in reducing postoperative retraction and improving overall patient outcomes in penile augmentation surgery. MATERIALS AND

methodsBetween September 2024 and March 2025, thirty-one adult male patients underwent suspensory ligament release via a reversed V-shaped suprapubic incision. The resulting retropubic space was filled using an autologous dermal-fat graft harvested from the lateral abdomen, customized to the assessed cavity volume. Transposed spermatic cord-associated fat pads were anchored to the base of the corpora cavernosa to reinforce the scaffold. Patients were followed up at 3, 6, and 12 months postoperatively. Penile length (flaccid and erect), complication rates, and patient satisfaction were assessed.

resultsAll wounds achieved primary closure with no major complications. Mean flaccid penile length increased from 5.23 ± 0.58 cm preoperatively to 6.89 ± 0.47 cm postoperatively (p < 0.001), and mean erect length increased from 7.78 ± 0.63 to 9.73 ± 0.71 cm (p < 0.001). No significant length loss was observed during the 12-month follow-up. Patient satisfaction levels were notably high, with 93.3% reporting satisfied or very satisfied.

conclusionThis vascularized, multilayer autologous scaffold approach effectively stabilizes length gains following suspensory ligament release. It represents a promising and safe strategy to minimize postoperative retraction and enhance long-term outcomes in penile augmentation surgery.
