Technical Aspects of Laser en Bloc Resection of the Bladder Tumor for Non-Muscle-Invasive Bladder Cancer

Abstract

In recent decades bladder cancer has become one of the most topical problems of modern healthcare due to its widespread distribution. This makes it necessary to investigate new effective methods of surgical treatment.Objective: Assessment of the effectiveness of en bloc resection of the bladder with tumor by analyzing scientific publications on this matter.Materials and methods: We have analyzed current articles related to this topic on the databases Pubmed and Google Scholar. The search was performed using the keywords «Bladder Tumor», «En bloc resection of the bladder wall», «non-muscle-invasive bladder cancer».Results: Most studies confirm the advantages of laser en bloc resection over other methods in terms of such parameters as the frequency of recurrence, macrohematuria, and the quality of morphological material.Conclusions: Laser en bloc resection of a bladder tumor without invasion of the muscle layer is a safe and effective operation that has a number of advantages over classical transurethral resection, namely: no obturator syndrome, high-quality material for pathomorphological research, low recurrence rate.
