Abstract
Aim
To analyze the clinical, imaging, and surgical factors that are associated with failed double-J stent placement in patients with obstructive uropathy due to cancer.
Materials and methods
An analytic, cross-sectional study was conducted. The variables analyzed were: age, sex, oncologic diagnosis, clinical stage, diagnostic time course, treatment received, preoperative laboratory studies (Hb, leuc, Cr, BUN, urea), imaging studies (US or CAT), and the surgical attempt to place the double-J stent. A comparative analysis was done between the failed and successful placement groups. Statistical analysis was carried out using the Mann-Whitney U test and the chi-square test, and finally, the odds ratio with a 95% confidence interval was employed.
Results
Of the 48 patients, 27 had failed double-J stent placement and 21 had successful placement. Risk factors for failed placement were elevated preoperative levels of urea ≥ 40 mg/dL (OR: 16.67, CI: 2.66-134.92 [P = .0001]), creatinine ≥ 2 mg/dL (OR:7.27, CI:1.41-42.25 [P = .004]), and BUN ≥ 40 mg/dL (OR:4.00, CI: 0.93-18.06 [P = .031]) and a low Hb level ≤ 9 mg/dL (OR:6.32, CI:1.37-21.55 [P = .005]), as well as a deformed trigone (OR:3.29, IC:1.18-9.19 [P = .002]).
Conclusions
Elevated preoperative levels of creatinine, urea, and BUN, and a deformed bladder trigone are markers for failed double-J stent placement.
期刊介绍:
Revista Mexicana de Urología (RMU) [Mexican Journal of Urology] (ISSN: 0185-4542 / ISSN electronic: 2007-4085) is bimonthly publication that disseminates research by academicians and professionals of the international medical community interested in urological subjects, in the format of original articles, clinical cases, review articles brief communications and letters to the editor. Owing to its nature, it is publication with international scope that disseminates contributions in Spanish and English that are rigorously reviewed by peers under the double blind modality. Neither journalistic documents nor those that lack rigorous medical or scientific support are suitable for publication.
