First Report of Laparoscopic Radical Nephroureterectomy Following Extraperitoneal Tubeless Umbilical Cutaneous Ureterostomy.

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
Introduction: Extraperitoneal tubeless umbilical cutaneous ureterostomy is a useful urinary diversion technique for patients with shortened ureters or high risk of upper urinary tract recurrence. However, radical nephroureterectomy following this diversion has not been previously reported. Case Presentation: A 67-year-old man underwent radical cystoprostatourethrectomy with extraperitoneal tubeless umbilical cutaneous ureterostomy for high-risk urothelial carcinoma with bilateral ureteral shortening. Twenty-four months later, left-sided upper tract urothelial carcinoma was diagnosed, and laparoscopic left radical nephroureterectomy was performed. Although dense adhesions necessitated partial small-bowel resection, complete nephroureterectomy was achieved without major complications. Conclusion: To the best of our knowledge, this is the first report of radical nephroureterectomy performed after umbilical cutaneous ureterostomy. This urinary diversion may represent a reasonable option for selected patients at high risk of upper urinary tract recurrence.
