Transurethral resection of prostate (TURP) is the most common operation performed for obstruction secondary to prostatic enlargement. Though considered as a safe procedure, occasionally life-threatening complications may be seen. Intravesical explosion, secondary to ignition by diathermy of the accumulated mixture of hydrogen, hydrocarbons and higher concentration of oxygen, is a rarely reported complication (only 38 cases reported until). We are reporting a 60-year-old man suffering from benign prostatic hyperplasia in whom during TURP bladder explosion occurred which was suspected early and immediately explored and repaired leading to a favourable outcome.
