Hello and welcome to HCM.
As an
Urologist, i can understand your anxiety.
You should write your age,sex,tests done so far and any treatment taken.
Urinary block after stone treatment,is due to stone fragments or
blood clots.
It can also be due to complications of the surgery,like,injury to urinary tube.

Tests to do are:urine routine,culture,blood routine,
creatinine,RBS,LFT,and uric acid. Then do an
ultrasound scan-KUB.According to reports,treatment can be advised. Dr.Matthew J. Mangat.
