I recently had a CT scan due to right flank pain and recurrent uti. I wondered if the portion under the contracts referencing a suspicious unidentified mass could be explained. Does this mean the kidney stone could not be identified on that portion of the test but it was identified without contrast or is this two separate items. A kidney stone and a suspicious mass.

Also do you see any other concerns. I am a 52 year old woman.

Dr. XXXXXXX 1/16/2014

I am scheduled for a cysto on February 13, 2015.
I had this done XXXXXXX of last year with a scope and biopsy of the kidneys and bladder.
I did not really understand the pathology report of the kidneys.
I have included the report. It does not seem to be definitive for a problem with the kidneys.
The final determination was carcinoma in siti of the bladder.
No stints were put in the ureters.

I had another cysto in october 2014 of just the bladder and a cytology of the fluids from the ureters.
The pathology determined carcinoma in siti of the bladder still present and atypical cells from the
ureters.
My question is about the cysto scheduled February 13th.
Will you be scoping the bladder and kidneys or just the bladder.

I am hoping that a biopsy of the bladder and a cytology of the fluids from the
ureters is all that is necessary to determine everything we need to know at this time.

I really do not want to have any stints put in.
That is my concern.

Thank you

I have been having brown colour urine and did an ultrasound. The impression reads as " right kidney shows mild fulness of pelvicalyceal system and dilated upper ureter echogenic calculus measuring 5.2mm is noted in the upper ureter 3cm distal to renal pelvis. Diffuse faty liver is noted"



Is it a tumour

Had a bladder infection - after 30 years. Infection went away, but still some discomfort. Had CT Abd/Pelvis w/contrast. There is prominence of the renal pelvis bilaterally, consistent with developmental extrarenal pelves, greater on the left. No ureteral dilation or stones. A component of mild chronic UPJ obstruction cannot be excluded. What does this mean ? I am scared !

I am a 62 year old male, i have had an ongoing UTI with a brief period of gross hematuria. A recent MRI shows an abnormal enhancement of the right collecting system especially involving the upper and lower pole calyces.in addition there is an abnormal thickening of the right renal pelvis and proximal ureter. The suspicion is for either infiltrating transitional carcinoma or an inflammatory etiology. Other than frequent urination, no pain, no fever, no weight loss, just stress while i am waiting to clear the e-coli infection so that internal testing can proceed and diagnose the problem. I have a history of frequent stones and presently have 2 in my right kidney What is the likelyhood of a positive outcome

doctor1 MD

INDINGS: The right kidney measures 12.7 cm in length. There is moderate hydronephrosis, with moderate pelviectasis and mild caliectasis. This does not change after the patient voided. No nephric calculi. The left kidney measures 12.1 cm in length. There is mild pelvi-caliectasis and hydronephrosis. This does not change following patient voiding. No nephric calculi. Both ureteral jets were identified. Prevoid bladder volume: 441.7ml. Postvoid bladder volume: 69.7ml. Impression IMPRESSION: Moderate hydronephrosis on the right and mild hydronephrosis on the left that does not change with voiding consideration may be given to dedicated CT scan of the kidneys with contrast to determine if a portion of the hydronephrosis/pelviectasis is secondary to an extrarenal pelvis or true mild/moderate hydronephrosis.
