Hi welcome to HCM...
You are complaining of dribbling of urine so it could be
urinary incontinence ...
Is there urgency for urination. ???
Pain while urination ???
Spinal trauma history ???prostate history ??
Etc.....
These above history needed to reach up to diagnosis ..
I would like you to investigate with ....
1.Urine routine and microscopic examination
2.Urine protein estimation
3.Prostate palpation per rectum and PSA
4.Urodynamic investigation
5.USG with post voidal residual urine
These investigation will helpful in identifying cystitis , UTI infections , BPH , stenosis etc..
If needed
cystoscopy and cystometry like investigation done ...
Depend on cause treatment guided ....
For prostate ex..
tamsulosin needed ..
If you not at all urinating and only urination by drop by drop than
urethral stenosis has to be ruled out by Uethroscopy ....
Advise : urosurgeon consultation...
Take care.
