I wouldn't say this was matter of poor surgery exactly. If all the proper procedures were followed and they made sure the urethra was clear by flushing it then most likely this is one of those rare instances where grit and sludge clogged the urethra and blocked the urines exit. He should have had a urinary catheter in place although two days later they might have tried removing it to see if he could urinate on his own. My main question is who was monitoring him as he should have had his urinary output checked as well as bladder size monitored hourly to every 2 hours. Something should have indicated that he was in trouble. Granted if this wasn't a 24 hour hospital then it may have occurred overnight. He had to be pretty painful before it ruptured. Of course the bladder was weakened after the surgery. Some questions may never be answered but you are very lucky he was in the hospital when this happened as the majority of these cases do not survive.

I sure hope that he recovers. Make sure once the type of stone is determined to keep him strictly on a special diet and medications and be super alert to urinary symptoms as if he blocked once it is likely he could do it again. Then there may be another surgery you might need to consider to make the opening larger for grit, crystals, and sludge to pass minimizing blocking.
