What did you CMG, cystoscopy, uroflometry show?
Your liver enzyme rise is unrelated to increased frequency of urination. There are various investigations which needs to be done to assess the cause of the increased night time frequency;
1) Cystoscopy; a small capacity bladder can be visualized by a camera. The other cause is bladder neck obstruction. A median lobe enlargement of the prostate is sometimes inadequately assessed by the digital rectal examination and ultrasound and cystoscopy can tell if this is responsible for the frequency.
2) Uroflometry tells about the total bladder capacity, peak urine flow, average flow and total voiding time etc, which can point to the cause of your symptoms.
3) Cystometrogram (CMG); this tells about the pelvic floor muscles, sphincters of bladder and bladder muscles.
4) Urine culture; a mild grade urinary tract infection can give night time increased frequency.
Please feel free for your follow up questions.
I would go for CMG and uroflometry first as they are non invasive tests. If they do not reveal anything, than only, I would proceed for the cystoscopy. Urine culture is always an essential investigation.
