oncourology. Currently, transurethral resection of urinary bladder (TUR-V) remains the gold
standard in the endourologic treatment of UBT. In the last decade many alternative endourologic
techniques have been proposed for the treatment of UBT.
Aim of the study. Comparative assessment of the efficacy of transurethral En Bloc resection of
urinary bladder tumors.
Materials and methods. In the period between 08.2017 β 12.2017, 25 patients with average age
of 57 years underwent endourological treatment of UBT at the Department of Urology and
Surgical Nephrology, Nicolae Testemitanu State University of Medicine and Pharmacy. Patients
were divided into two treatment groups: first group - transurethral En Bloc resection of UBT (8
patients), second group β TUR-V of UBT (17 patients). All patients were evaluated after 3
months by cystoscopy whit narrow band imaging (NBI).
Results. Average duration of intervention: 39 min vs 33 min. The rate of transitional haematuria
and postoperative infections was similar. During NBI cystoscopy tumor recurrence was
determined in 3 cases in TUR-V group, and no recurrences in En Bloc resection group. In the En
Bloc resection group additional tumors with different localization were found during NBI
cystoscopy.
Conclusions. Transurethral En Bloc resection of UBT is an effective method in the treatment of
UBT. Results of treatment using En Bloc resection are better that conventional TUR-V of
bladder tumor. Another advantage of transurethral En Bloc resection of UBT is a better staging
of tumor process due to the resection of all urinary bladder wall layers which is very important to
determine postoperative tactics
