Long-term outcomes from a multi-institutional experience with prefabricated composite gracilis-buccal mucosal flap for reconstruction of devastated urethras.

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
purposePatients with devastated bulbar urethras have limited surgical options to restore normal upright voiding. We investigated the long-term feasibility of using two independently vascularized urethral hemi-plates lined with buccal mucosal graft (BMG) to treat these patients.
methodsA multi-institutional retrospective review was conducted for patients that underwent this staged repair. In stage-1, the affected urethra is dissected and removed or prepared for a dorsal inlay augmentation. Two BMG segments are harvested; one graft is quilted on corpora cavernosa and urethra, creating an augmented perineal urethrostomy, and the other is quilted on the exposed distal gracilis muscle. Stage-2 utilizes the gracilis-BMG composite to recreate ventral bulbar urethra. The primary outcome measure was stricture recurrence. Secondary outcome measures included patient-reported outcome measures (PROMs).
resultsFive patients with mean age of 50 years (45-56) underwent staged repairs at two institutions between 7/2014 and 4/2016. All patients presented with suprapubic tubes and underwent at least one prior failed repair (1-9). Mean stricture length was 7.2 cm (5-9). Mean time between stage-1 and stage-2 repairs was 6.2 weeks (1-10). At a mean follow-up of 61 months (39-87), there were no recurrences. The mean uroflow was 20 cc/s (9-42) with a mean PVR of 59 cc (0-157). Four patients completed post-operative surveys; all reported at least a moderate improvement in their condition on Global Response Assessment (GRA), and a mean IPSS of 7.3 (0-26).
conclusionsOur bi-institutional case series demonstrates that this technique is a feasible option for devastated urethras with long-term durability.
