Effectiveness of Antegrade Access in Bladder Tumors With Inaccessible Urethra

Inaccessible urethra with no retrograde endoscopic access due to multiple/diffuse strictures or multiple urethrocutaneous fistulas with acute urinary retention due to posturethral instrumentation (transurethral resection of bladder tumor [TURBT], or TURBT with transurethral resection of the prostate [TURP]), is a rare entity. Management of such a case with a bladder tumor for TURBT/surveillance cystoscopy poses a great challenge. The authors present 12 cases of bladder tumor with inaccessible urethra, 10 cases due to multiple strictures (post-TURBT and/or TURP), and 2 cases due to urethrocutaneous fistulas (post-TURBT), who presented to our emergency department with acute urinary retention. Emergent suprapubic catheterization was used as a temporary treatment method.Key words: Suprapubic cystostomy, Inaccessible urethra, Bladder tumors, Tract seedlingBladder tumors are the most common neoplasm of the lower urinary tract, comprising 6% of all malignancies in men and 2% of those in women.¹ A majority of patients present with gross painless hematuria, usually as the sole presenting symptom.² Bladder carcinoma is unique among human neoplasms in that many of its etiologic factors are known; the urologist should be aware of the possible occupational exposures to urothelial carcinogens.³ Initial symptoms of urothelial carcinoma of the bladder (UCB) include microhematuria, painless macrohematuria, and/or irritative voiding symptoms, and require further investigation. Carcinoma in situ of the bladder causes irritative lower urinary tract symptoms (LUTS) more often than does papillary UCB. Histopathologic evaluation is necessary to assess stage and grade with sufficient certainty after the appearance of bladder tumors.⁴ Bladder tumors spread by implantation in abdominal wounds, denuded epithelium, resected prostatic fossa, or traumatized urethra⁵; implantation occurs most often with high-grade tumors.
