Long-term urinary tract effect of ileal conduit after radical cystectomy compared with bladder preservation: a nationwide, population-based cohort study with propensity score-matching analysis.

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
objectiveIleal conduit urinary diversion (ICUD) is the most common procedure after radical cystectomy. Although complications have been reported, few patients with ICUD and bladder preservation controls have been available for long-term follow-up. This study compared the long-term effect of structural changes after cystectomy with ICUD to that in bladder preservation controls.
designA retrospective nationwide cohort study.
settingData retrieved from the Taiwan National Health Insurance Research Database.
participantsThe National Health Insurance database was explored for patients diagnosed with bladder cancer between 1997 and 2006. Only cancer-free patients without chemotherapy and other types of urinary diversion who lived for >5 years were included in the analysis. OUTCOME MEASURES: Patient characteristics, comorbidity and postoperative urinary tract disease were statistically analysed and compared. Cox proportional hazards model was used to evaluate the incidence rates of outcomes after adjustment for covariates. Propensity scores analysis was used to balance the clinical parameters between groups. The primary outcomes were postoperative new-onset urinary tract disease such as urinary tract infection (UTI), UTI with septicaemia and chronic kidney disease (CKD), or calculus of kidney and ureter.
resultsThere were 11 185 patients included in our cohort, among which 703 (6.3%) and 10 482 (93.7%) patients received ICUD and bladder preservation procedure, respectively. Compared with patients who only underwent a bladder preservation procedure, those who had undergone ICUD after cystectomy were independently associated with postoperative de novo urinary tract disease. Propensity score analysis (1:4) was also performed. ICUD contributed to significantly higher new-onset UTI, UTI with sepsis and CKD (HR=1.30, 3.16, 1.35, respectively) compared with bladder preservation procedure after adjustment for age, gender and comorbidities.
conclusionICUD after radical cystectomy was associated with a higher incidence of UTI, UTI with septicaemia and CKD during long-term follow-up than the incidences following a bladder preservation procedure.
