Holding urine for too long can cause the bladder to burst
Severe urinary retention and the resulting buildup of intravesical pressure can indeed cause the urinary bladder to rupture, a condition documented across multiple clinical case reports.
The retrieved papers provide multiple clinical case reports and discussions confirming that severe urinary retention and bladder over-distension can lead to spontaneous bladder rupture due to increased intravesical pressure. There are no papers contradicting this physiological phenomenon.

Documents a case where urinary retention from a urethral stricture led to spontaneous bladder rupture.
