Brief Answer:
Such finding is not critical and can also be a part of normal study

Detailed Answer:
Hi XXXXXXX,
Thanks for writing in to us.

I have read through your query in detail.
Let me start my answer with a small description of the kidneys, ureter and urinary bladder.

The collecting system of the kidney is made of renal calyces and pelvis. This collects the urine formed in kidney and transports it through the ureter (tubes connecting kidneys and urinary bladder) to the urinary bladder. The pelvicalyceal system is the mouth of the kidney where it connects with the upper end of the ureter.

I guess that you have got ultrasound scan done and it shows mild fullness of the pelvicalyceal system in the right kidney, that is a term applied to increase in diameter of the collecting system in your right kidney.

It is not a critical situation and please do not worry if you do not have any urinary symptoms. Since it is mentioned as mild fullness and no kidney stones have been found, therefore
(i) It can be that your bladder was completely full at the of ultrasound scan
(ii) Your kidney pelvicalyceal system is appearing full by itself (extrarenal pelvis) and is an extension of normal appearance.
(iii) Rarely an infection of urinary system and kidneys (recent or old) can cause such a finding but this is likely only if you have symptoms like pain in the region of kidney and problems like burning urination or discoloration of urine or any kidney infections in the past.
(iv) Stones in kidney or ureter can also cause fullness of pelvicalyceal system and since you do not have any stone therefore this does not apply to you.

It is important to know if your scan was repeated after passing urine ans still there was persistent mild fullness of the pelvicalyceal system on right side.

Hope this answers your question. Please feel free to correct any oversight in my interpretation of your problems and discuss them in detail as per your requirements.

Hope your query is answered.

Brief Answer:
Rare possibility of a recently passed out stone can explain both findings

Detailed Answer:
Hi XXXXXXX,
Thanks for writing back with an update.

As there is blood cells in your urinalysis therefore the rare possibility of having passed out a recent stone can explain both the above findings. What might have happened is that the stone has passed from the kidneys and through the ureter in to the urinary bladder. This can lead to a small injury in the sensitive lining of the ureter causing the slight bleeding. Please discuss this in detail with the urologist and also get other investigations done if blood in urine persists.

Please drink lots of water and fresh juices and visit the washroom as required. Do not hold urine for long periods.

Hope your query is answered.
