OBJECTIVES:

To determine the incidence of bladder perforation detected during transurethral resection of the bladder due to urothelial cancer and its association with risk factors, diagnosis, treatment, and prevention to reduce complications that modify patient outcome, increasing the risk for recurrence, progression, and metastasis.

MATERIALS AND METHODS:

A retrospective and prospective study was conducted on patients that underwent transurethral resection of the bladder due to non-muscle-invasive urothelial cancer at the Urology Service of the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán, within the time frame of 1987 to February 2017. Cases of bladder perforation detected during the procedure were described, and the demographic and clinical variables were evaluated.

RESULTS:

Of the 556 patients that underwent transurethral resection of the bladder, 7 had detected bladder perforation: 4 were cases of extraperitoneal perforation and 3 were intraperitoneal. One patient with extraperitoneal perforation presented with extravesical recurrence that was treated conservatively.

CONCLUSIONS:

The incidence of bladder perforations found in our study was low. It was associated with age, tumor grade, and number of resected tumors, but not with BMI. Unlike descriptions in the literature, extravesical recurrence was not associated with intraperitoneal perforation. The urologist should be aware of the complications of the procedure and treat them opportunely.
