[Show abstract][Hide abstract] ABSTRACT: On occasion, difficulty will be encountered removing an indwelling urethral catheter. This may be as a consequence of failure of the catheter balloon to deflate. This article reviews the published data on managing the non-deflating Foley catheter balloon, and suggests an evidence-based sequence of interventions to deflate the catheter balloon.

[Show abstract][Hide abstract] ABSTRACT: A cohort of 113 patients underwent prospective evaluation with a panel of seven microsatellites, on chromosomes 9, 13 and 17. Thirty-seven patients had histologically confirmed bladder tumors, 53 patients had a history of previous transitional cell carcinoma of the bladder (TCC) but normal cystoscopies (control Group 1), and 23 patients had no previous history of TCC and normal cystoscopies (control Group 2). Urinary DNA was considered to show a deletion if an allele was reduced by more than 50%, and this was considered diagnostic of bladder carcinoma. The sensitivity of the method was 50%, positive predictive value was 80%, and specificity was 93%. Reducing the threshold for defining allelic loss increases sensitivity, but reduces specificity. The concentration of urinary DNA in the sample did not influence detection rate. The grade and stage of the bladder tumor did not influence the likelihood of detection. This method detects bladder carcinoma with high specificity, and increasing the number of microsatellites used should increase sensitivity.
