INCIDENCE OF BLADDER PERFORATION AFTER ENDOSCOPIC TREATMENT FOR SUPERFICIAL BLADDER TUMORS

ABSTRACT
Purpose: In this descriptive study we evaluated the frequency of bladder perforation after transurethral resection of superficial bladder tumor in institute of kidney disease hayatabad Peshawar.
MATTERIAL AND METHODS: The Transurethral resection done on 2000 patients presented with superficial bladder tumor from July 2008 to July 2012.
RESULTS: The prospective study was carried out by 2000 patients. Among 2000 patients male and female distribution was 1600 (80%) and 400(20%) respectively. The average age of the patients was 65.6 +10 years (30 to 80) that were endoscopically treated. The average size of the bladder tumor on cystoscopic evaluation was 26+10mm in diameter. The bladder perforations were more common in female might be due to their thin bladder wall. The only statistically significant difference between patients with and without extravasations was in patient age and sex, tumor size, localization, number of foci, tumor grade and stage. The perforations were mostly related with a tumors located at the dome of the bladder in 4 cases (5%). The perforations were mostly extra peritoneal and conservatively treated with intravesical
catheter for 10 days.
Conclusions: The extravasation of urine (asymptomatic perforation) after transurethral bladder tumor resection may occur much more frequently than expected.
