Outcomes of Intradetrusor OnabotulinumtoxinA Injection in Adults with Congenital Spinal Dysraphism in Tertiary Transitional Urology Clinic.

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
purposePublished data regarding intradetrusor injection of onabotulinumtoxinA in adults with congenital spinal dysraphism are scarce. In this study, we retrospectively investigated the outcomes of intradetrusor injection of onabotulinumtoxinA in this setting. MATERIALS AND
methodsBilling codes were used to identify 149 patients who underwent onabotulinumtoxinA injection between 2012-2016 at our tertiary transitional urology clinic. Charts were then reviewed to identify patients with congenital spinal dysraphism.
resultsA total of 18 patients with the mean age of 20.76 (±3.03) years at the time of 1st onabotulinumtoxinA injection were identified. All patients had urinary incontinence. Urinary incontinence improved by injection of 200 or 300 U of onabotulinumtoxinA in 81.2% of patients and 63.6% of them became dry (p= 0.023). Mean glomerular filtration rate before and 13.3 (±9) months after treatment was 100.2 (±17.2) and 120.1 (±16.6) mL/min/1.73 m2 respectively (p= 0.41). Baseline hydronephrosis improved in 3 of 4 patients. Repeat urodynamic study after injection was done in 11 patients who did not clinically improve or who had loss of bladder compliance at baseline (29.3 Vs. 67.2 ml/cmH2O). Mean maximum cystometric capacity before and after injection was 310.1 and 380.2 mL (p= 0.045). Mean bladder compliance before and after treatment was 29.2 and 28.7 ml/cmH2O respectively (p= 0.48) in this high risk group.
conclusionsIntradetrusor onabotulinumtoxinA injection may improve refractory urinary incontinence in selected adults with spinal dysraphism. However, despite improvement in maximum cystometric capacity, bladder compliance does not improve following therapy in patients who had loss of compliance at baseline.
