Endoscopic resection of bladder urothelial neoplasm in a child: a case report

Abstract

Bladder tumour, especially urothelial neoplasm, is a very rare condition in paediatric age. That is why true and accurate information on biological grade of malignancy and, correspondingly, the surgical management is absent. However, the majority of physicians take the view that this type of tumour has a low grade of malignization and recurrence, even after the endoscopic excision of neoplasm in paediatric patients. Purpose - to describe a clinical case of surgical management of the bladder urothelial neoplasm in a child by means of minimally invasive equipment. Clinical case. Endoscopic methods of surgical treatment are widely used in paediatric patients with the urinary tract conditions in our clinic. The transcutaneous surgical treatment of bladder conditions has been employed in paediatric patients since 2010. For example, it was used for the removal of ureterolith impacted in the bladder neck and foreign bodies of the bladder, as well as the bladder urothelial neoplasm excision. We also tried to use it for visualisation of the posterior urethra rupture length through a cystoscope, which was put into the epicystostomic hole of the posterior urethra together with the simultaneous urethroscopy (for the purpose of the directed illumination during the urethroscopy). However, due to the long length of the posttraumatic urethrostenosis, it was impossible to achieve the illumination and catheterisation of the urethra during the urethroscopy in the site of damage. The clinical case of the minimally invasive resection of the bladder urothelial neoplasm in a child is presented in the article. Minimally invasive techniques give the opportunity to perform even the radical operations with the perfect cosmetic result and minimal injury that is very important in the paediatric patients. The research was carried out in accordance with the principles of the Helsinki Declaration. The informed consent of the patient was obtained for conducting the studies. No conflict of interests was declared by the authors. Key words: bladder neoplasm, transcutaneous cystoscopy, neuromuscular bladder dysfunction, children.
