To accommodate the small size of the infant urethra, finer, more flexible tubes are often used for urinary catheterization in the pediatric intensive care units. These tubes have the ability to knot in the bladder, occasionally requiring surgical removal. ⋯ Review of the literature from 1975 to 2000 identified 19 cases of urethral catheter knotting in the pediatric bladder with two reports of prostatic urethral involvement. Herein, we describe the first reported instance of catheter knotting within the penile urethra and describe the surgical technique employed for its removal.

Practice Guideline Guideline
Adjuvant chemotherapy for deep muscle-invasive transitional cell bladder carcinoma - a practice guideline.
To examine the role of adjuvant chemotherapy in the treatment of patients with deep muscle-invasive transitional cell carcinoma (TCC) of the bladder who have undergone cystectomy. ⋯ As randomized trials have not proven a benefit in overall survival, adult patients with deep muscle-invasive TCC of the bladder should not be routinely offered adjuvant chemotherapy following cystectomy. Disease-free survival may be improved by adjuvant chemotherapy, but it is unclear whether this improvement compensates for the detrimental effects of chemotherapy. If a patient chooses adjuvant chemotherapy to improve disease-free survival they should be made aware of the lack of proven overall survival benefit, and a cisplatin-based combination chemotherapy regimen such as MVAC or CMV is recommended. RCTs of gemcitabine-cisplatin and dose-intensive MVAC plus G-CSF in the setting of metastatic TCC of the bladder provide indirect evidence that these regimens could offer equivalent benefit to MVAC and CMV but with less toxicity in patients with muscle-invasive disease. The use of these regimens in the adjuvant setting after cystectomy is currently being evaluated in a randomized trial (EORTC trial 30994).
