Management of Catheter-Related Bladder Discomfort in Patients Who Underwent Elective Surgery.

Objective: Despite the various treatment and prevention options for catheter-related bladder discomfort (CRBD), many uncertainties persist in clinical practice. To systematically review the literature on the management of CRBD in patients who underwent surgery. Materials and Methods: Eligible, randomized controlled trials were identified from electronic databases (Cochrane Central Register of Controlled Trials, Medline, and EMBASE) without language restrictions. Selection criteria, methodological rigor, and risk of bias were evaluated by two independent reviewers using Cochrane Collaboration's tools. Results: A total of 1441 patients from 14 articles published between 2005 and 2014 were included. Data heterogeneity precluded meta-analysis; therefore, data were synthesized narratively. Compared with nonurological surgery, CRBD is frequent and occurred immediately after urological surgery, especially after transurethral resection of the bladder tumor (TURBT). Data from included studies suggested that muscarinic antagonists, anesthetics, antiepileptics, and analgesics were associated with significant improvement in symptoms and reducing the incidence of CRBD, compared with placebo. Anticholinergic agents and antiepileptics (gabapentin and pregabalin) administered 1 hour before surgery reduced the incidence and severity of CRBD in the immediate postoperative period. Tramadol and ketamine are centrally acting opioid analgesics with antimuscarinic actions, which effectively prevent CRBD when administered intravenously. Paracetamol administered was also effective for the management of CRBD. Additionally, we perceived that TURBT is the surgical procedure that is the most refractory to treatment. Conclusions: Muscarinic antagonists, anesthetics, antiepileptics, and paracetamol appear to achieve the greatest improvement in the clinical symptoms and a significant reduction in the incidence of CRBD compared with placebo. Although these studies observed a high incidence of intervention-related side effects, in general, patients tolerated these treatments well.
